Top 5 Most Reliable Electric Cars For 2018

Bolt EV arrives in UAE

NOV 10 2018 BY JIM GORZELANY 83

We all know electric cars are more reliable than gas, but which are the most reliable of the electric bunch?

You may find it to be the proverbial brave new world if you’re in the market for your first electric vehicle. Though the concept of driving an auto that plugs into a wall socket might seem futuristic, the underlying technology has been around since the mid 19th Century. Advancements in battery technology enable the latest EVs to run for as many as 300 miles or more on a charge.

But as with any automotive purchase, EV shoppers may foster concerns about a given model’s long-term reliability. At least theoretically, electric cars should prove to be less problematic than their gasoline-powered counterparts. Electric motors are inherently less complex pieces of machinery than are gasoline engines. EV transmissions utilize only a single forward gear instead of as many as 10 in a conventional automatic transmission. Plus, EVs require less maintenance by sidestepping over two dozen components – including spark plugs, drive belts, the oil pump, and water pump, among others – that would at some point need replacing.

On the downside, a vehicle’s battery pack will eventually degrade. Having the battery swapped out can be an expensive affair; a replacement battery for the Nissan Leaf reportedly costs $5,500. Fortunately, federal law mandates automakers guarantee their EV batteries for at least 8 years or 100,000 miles.

For its part, Consumer Reports says EV reliability has been stellar thus far. Among newer models, CR says the Chevrolet Bolt EV is expected to be “very reliable” after just debuting for the 2017 model year. What’s more, CR says if they’re properly maintained any EV can easily keep running for 200,000 miles or more.

However, as we all know, some cars ultimately prove to be more trouble than others over the long haul. Unfortunately, finding information on a given EV’s long-term reliability can be difficult. Ratings from the two main sources we consulted, Consumer Reports and JD Power, tend to be limited to the segment’s most popular models. That’s due to a lack of owner-survey feedback on EVs having relatively miniscule sales, especially those that aren’t offered nationwide.

We’re featuring the five nationally available electric cars from the 2018 model year that our sources project will be the most dependable over time.

5. BMW i3

The battery-powered version of the futuristically styled BMW i3 gets a 3 out of 5 rating for reliability from Consumer Reports and a 3.5 out of 5 score from JD Power. (There’s also a “range extender” version of the i3 that adds a small gas engine, and is considered more of a plug-in hybrid than a pure EV.) CR ranks the i3 as being above average in all aspects of mechanical durability, from powertrain to in-car electronics, based on owner surveys from the past three model years. MSRP (including destination charges): $45,445.

4. TESLA MODEL 3

A recent entry among EVs, Consumer Reports projects the sleekly styled Tesla Model 3 will be acceptably reliable, giving it a 3/5 rating. While there’s no details as yet regarding potential problem spots due to a lack of owner feedback, CR gives the car an average score here based on admirable owner reports for the automaker’s Model S. It’s not yet rated by JD Power, however. MSRP: $50,200.

3. NISSAN LEAF

The Nissan Leaf has been on sale since the 2011 model year, and has been one of the segment’s top sellers, which makes data about its past performance more plentiful than with most newer electric vehicles. Consumer Reports rates it 4/5 for reliability, with JD Power giving it an average 3/5 score. CR rates it highly in just about every mechanical category except for the Leaf’s climate control system. MSRP: $30,885.

2. TESLA MODEL S

Available since the 2012 model year, past-performance information on the flagship Tesla Model S sedan should be solidly set. Consumer Reports rates it 4/5 for reliability based on owner surveys from the last six years. Curiously, JD Power has yet to issue a dependability rating for brand’s biggest seller. CR gives it above average marks for reliability in virtually all categories, including for its complex tablet-based dashboard electronics. MSRP: $75,700.

1. CHEVROLET BOLT EV

More or less tied with the above Model S in this regard, Consumer Reports says the Chevrolet Bolt EV is the brand’s top-rated vehicle. It’s CR-rated at 4/5 for reliability, which is unusually high for a recently introduced model. Scoring highly in most mechanical aspects, the only below-average score is with its in-car electronics. For its part, J.D. Power gives the 2018 Bolt a predicted reliability rating of three out of five, which is average among all cars. MSRP: $37,495.

Great example of how EVs are more reliable, given the Bolt EV is GMs best vehicle for reliability. Surprised to see i3 on the list, it looks like it has improved a lot.

Alex

I don’t know how consumer reports classify reliability. Looking at rankings, there are a few ICE cars with rated with a 5.

Viking79

A while back CR mentioned that Bolt EV was GMs most reliable car, but I don’t subscribe anymore so don’t know if they still say that.

Dudamus

Thats excellent news.

TCannon

I’ve subscribed to CR for decades. They poll their subscribers about their purchases and they ask detailed questions about repairs needed, whether they’re asking about a car or a refrigerator.

Al D

Quite a few ICE vehicles are more reliable than any if these EV’s. This year’s Leaf is expected to be the only EV with a very reliable rating. However, I expect some problems to emerge as Nissan extends the Leaf’s range in the coming years, making it heavier.

Nick

How is it a great example? JD power has either not rated them or rated them 3/5, I.e. average.
The article mixes theoretically reliable with actually reliable when there isn’t sufficient available data to make a conclusion.

WARREN

Surprised JD Power’s gave the i3 the higher rating than the Bolt, yet the i3 is last on this list and Bolt first, based solely on CR ratings. I would venture to guess the JD surveys are just as accurate and detailed as CRs. At worst, a draw.

3laine

JD Power is garbage. A quote from their VP of Global Research:

“The Mini brand was last [in DEPENDABILITY], falling from 32nd out of 36 in 2010, because of a number of problems with the Cooper. The biggest problem areas were interior controls and seats which owners find “difficult to operate,” rather than mechanical quality.”

So, interior controls that are “difficult to operate” lower the result in a DEPENDABILITY study?

Complete nonsense.

MamaBear
Ummm, the article DOES place the Bolt first. They just started with #5/i3 and worked backwards, ending with #1, the Bolt. I have had the Bolt and now the S. The Bolt was a damn good car. I did however have some battery/charger issues so I sold it and got the S. Totally different animals. You get what you pay for. The S is beyond amazing – but considerably more. That said, the Bolt is a solid choice. My father has the 3- super impressive fun car with great mileage. My son had the i3 which we loved until it was involved in a hit and run accident. It’s battery is small, but it was a fun car- although bad in the snow and had two sizes of tires which makes traveling to rural areas less likely to carry a replacement if needed. My vote, in order: S, 3, Bolt and it ends there due to battery size. Unfortunately, there are huge price differences- but the software factor also makes a huge difference and makes planning a road trip to be a breeze in a Tesla. Also, super charges make long trips more time comparable to ICE cars gassing up… Read more »
Get Real

Now that I have driven my LR, rear motor Model 3 for a week I fully agree with everything MamaBear wrote.
My Bolt EV is a nice hot hatch type electric car with excellent range but the Model 3 makes it seem like a toy wind-up car in comparison.

The Model 3 feels like its carved from a solid piece of of aluminum billet. It drives and handles like its on rails with an instant thruster attached.

The Bolt’s torsion beam rear suspension hinders its handling and as a high powered FWD it gets noticeable torque steer under maximum power whereas the Model 3 has incredibly smooth and tight handling and acceleration.

Al D

According to Consumer Reports, the Bolt is expected to have just average reliability. There are several GM vehicles that are rated much better than average. Of course, once the bugs are out, the Bolt could provide top reliability if GM uses very durable components other than the battery and motors.

William

Best to check Nissans NEW price increase, in the cost of new batteries, as “a replacement battery for the Nissan Leaf reportedly costs $5,500.”

It has been reported, that a significant price increase, in the Leaf 24 kWh replacement battery, has at least a few Nissan Leaf (mynissanleaf) loyal fans considering abandoning permanently, the Nissan Leaf EV ship.

$ 8,500. is a substantial cost increase.

Scott

Or you could get a lightly used pack for $3k from the salvage yard.

TCannon

Or you can buy an EV with a battery conditioning system that keeps it at optimal temperature for a much longer life without degradation.

William

That just makes way too much sense!🤣🍃😂

Martin Lacey

Transportevolved recently broke this story.

Dudamus

The problem might be since 04/2013 the batteries are lasting way longer than even Nissan imagined.

jim stack

LEAF batteries have NOT been lasting in HOT Greater Phoenix, Georgia and SoCal. Anyplace it gets HOT. Their new lizard batteries have not been any better. If they call that reliable CR better get back to basics. A replacement is over $7K now and it will also degrade in the HEAT. Bigger capacity battery packs are even more expensive.

Dudamus

And the great news is that most LEAFs are lasting 120,000 to 240,000 miles. Great batteries since 04/2013, Outstanding cars. Just make sure the range suites your needs. IF you use the cars 20-80% charge they will last a long long time and the heat doesn’t matter.

Rick

Model S in second spot, I have to agree… it never let me down unlike an ICE car I owned a while ago.

Threader

Might not of been your experience with the S but door handles that cease to function and cost $750 + to replace. Give me an old fashion mechanically actuated door handle with my EV please. M3 should be in second spot no the S.

earl colby pottinger

Should they not be under warranty?

Bill Howland

Last I heard, if out of warranty, the door actuators (which will constantly fail in cold locales), are $1200 per door. First in Germany, and later in the states – private people have machined Stainless Steel racking parts which solve the problem. Tesla continues to replace the troublesome rack with the same troublesome rack.

This is why many “S” owners have been DIY’ers, as some articles here in the past have showcased.

Jazz

Should be number 1 and Model 3 in second place. I love my Model 3 and it’s performed like a champ.

ModernMarvelFan

Based on this, every traditional automakers that are known to have worse than average quality should switch to EVs… (FCA, Ford, GM, Mercedes, BMW, Volvo, Jaguar should do it fast just for reliability reason).

Antonio Briz Ena

Bolt stop sellimg in Europe. So not realible at all.

Threader

Your confusing “availability” with reliability

Guillaumef

You’re confusing “your” with “you’re”…

“You’re going to lose your dog if you don’t fix that loose collar.”
Those are two of the errors that drive me craziest. There, their and they’re are close behind.
My writing is not even close to perfect, but I try to avoid the easy to notice errors.

Jp

“Than” and “then” is a biggy too !!

Counterpoint

According to True Delta, which gives real world crowdsourced driving data, the Leaf has exceptional reliability, the Bolt has above average reliability, the i3 is pretty bad, and all Teslas are awful.

And if you compare best selling plug-in hybrids, the Prius Prime has exceptional reliability and the Volt is roughly average (1st gen above average, 2nd gen below average)

I can’t wait until either Toyota comes out with a compelling full electric car or Tesla improves its reliability enough that their cars are consistently more reliable than average

Raymond Ramirez

You have a very short EV memory. Toyota did produce the RAV4-EV TWICE. The second time it used Tesla’s power train and battery, such that the DIC displayed “Powered by Tesla” when powered up. You can search anywhere on the web and at past InsideEVs articles that described both RAV4-Ev versions. It does appear in the older EV tables. So if Toyota dropped their own EVs, they have no future plans except the Mirai Fool Cell model, which is an EV by InsideEVs standards.

Prsnep

“So if Toyota dropped their own EVs, they have no future plans except the Mirai Fool Cell…”

Your logic was on thin ice simply because you wanted to write “fool cell” because that makes you sooooo clever. GM killed the electric car and here they are with the Bolt. If you remember, it was selling in significant volume much before the Model 3. Toyota didn’t think they could make reliable electric cars 10 years ago. A lot has changed in that time. And so has Toyota’s view on electric cars.

earl colby pottinger

Have you tried using the website? I just did, it give Tesla very bad ratings but then when you try to follow the links that report the problems you get NO PAGE FOUND.

So the website give Tesla bad rating but cannot tell you what is so bad about the cars. This is not what I expect of a ratings site.

earl colby pottinger

What is this? 5 views and then I am kicked out as a non-member? Talk about a site I can not use.

Pushmi-Pullyu

“According to True Delta, which gives real world crowdsourced driving data, the Leaf has exceptional reliability, the Bolt has above average reliability, the i3 is pretty bad, and all Teslas are awful.”

This directly tracks with cheaper cars being more “reliable” simply because they have fewer parts, fewer luxury touches, and fewer things in them which can break or malfunction. Likewise, my old typewriter was more “reliable” than any desktop computer I’ve ever owned, but that certainly doesn’t mean that I want to go back to using the typewriter!

I suppose there is an argument to be made for a “no frills” car having fewer things in them that can go wrong, but to compare reliability across the board instead of within a price range, seems at the very least misleading, if not outright pointless.

Bill Howland

Where I disagree with the author is in such statements as “We all Know electric cars are more reliable”.

If you are talking about my current dinky ‘stable of cars’, a 2014 Caddy GEN 1 ELR, and an early 2017 BOLT ev, then I could agree with that statement, as those cars have both been quite reliable – especially with the powertrains. Little gremlins with the ancillary gadgets have crept in however.

While they’ve both been overall reliable, the VERY COMPLICATED ELR has overall been somewhat more reliable than the VERY SIMPLE BOLT ev (with only 2 options – heated seats and heated steering wheel).

To paint ‘all electric cars’ with such a broad brush is inaccurate – even if judged by the comments here, since some ICE only vehicles beat the electrics.

Simplicity has never had much relation to reliability. YOU’D THINK “We would all know” that.

MamaBear

“Spoken” like a real luddite…

Dudamus

From what I see on facebook post and Ev forums I woluld agree with True delta. The LEAF has exceptional outstanding reliability. Much better than the Prius;s. Corrollas, Camrys, CRVs we have owned in the past. If the limited range suites your needs it will be the last car you will ever need in your lifetime. Try to make sure you get a LEAF with twice the range of your commute and it will go forever. jut avoid the pre 04/2013 models unless they have the lizard replacement batteries. The lizards are outstanding and almost totally heat immune.

But the LEAF is a family car for around town so it really shouldn’t be compared with some of the other cars.

Dudamus

From what I see on facebook it seems true delta has an accurate representation of those hybrids you mentioned too. Elon needs to make More BETTER cars.

MamaBear

Hybrid is code for half pregnant. You still have ICE issues! Still, it’s a step in the right direction. Once you go EV, you won’t go back!

Chris O

” a replacement battery for the Nissan Leaf reportedly costs $5,500″…. yeah scratch that, according to Transport Evolved Nissan silently bumped that up to $8,500. Apparently to do with the old chemistry being discontinued. So now you have a battery pack that wears out relatively quickly due to absence of active cooling that will most likely cost a lot more to replace than the car is worth in most cases, so maybe Leaf should be scratched from the reliability list all together.

Miggy

The Model 3 is now the Best Selling EV in the World for 2018 YTD.
http://ev-sales.blogspot.com/search/label/World

theflew

Just not as reliable as others on the list.

Xavierstark

Like the leaf?

They are joking about that.

We all know how battery degradation works on all of that list cars.

Raymond Ramirez

That just as good as posting that the cheapest McDonald is the best selling hamburger in the world. Most sold isn’t the best quality.

Will

How can a car that is only one year old be judged on reliability? I think it should only include cars more than three years old and only include items that prevent operating the vehicle like power train or environmental controls. Entertainment systems and other accessories should not be part of the rating. This would mean, correctly I think, that the only models we have real reliability data at all are the Leaf and Model S. The Leaf should score low because of now predictable battery problems and the S higher but not high because of few issues that prevent operations, like the door handels. Everything else is fit and finish and has nothing to do with reliability of the car.

Counterpoint

It’s interesting you mention that, because everywhere I’ve looked the Leaf rates as highly reliable and older Model S cars as very unreliable. While you’re probably right that the Leaf problems, while rare, tend to be battery-related (and thus serious) while Model S problems are more about door handles and fit and finish issues; there seem to be an awful lot more problems with the Model S by a strictly numerical standpoint. And that is something that will hopefully change as Tesla improves its manufacturing processes.

Pushmi-Pullyu

The problem with that argument is that in general, luxury or “premium” cars as a class are going to rate badly on “reliability,” simply because they have more parts, and more things that can break or malfunction. Yeah, the Model S and Model X, on average, need service more often than a low-priced car like a Leaf or a Honda Civic/ Accord or a Toyota Corolla, but if you were to compare Tesla cars to their peers, Mercedes-Benzes and Audis and BMWs and the like, then you’d see they are much closer to average reliability for comparable cars.

If you want to get a no-frills, bare-bones car because it’s more “reliable”, then by all means buy one. But generally, people make their car buying decisions on a lot of factors, of which reliability is only one.

If reliability was the be-all-and-end-all of what’s important in a car, then the Tesla Model S wouldn’t score #1, year after year, on Consumer Reports‘ customer satisfaction survey. And the Model X wouldn’t score in the top 10, either.

Bill Howland
To some of us, reliability *IS* important. Especially those of us who have to PAY for EV’s, something which will never be your concern since you’ll never purchase an EV of any kind. And while Ive been unfairly disparaged for cataloging problems with my 2011 Tesla Roadster, I find it JUST MORE THAN A LITTLE INTERESTING, that when you go to Drive Electric events or my Canadian Car Club (since I’m in a border state), there are almost no Roadsters being showcased. I suppose somewhere there are still several (probably more overseas than in the states ironically), but the Canadian car club, initially having over 1/2 Roadsters and the rest Leafs and Volts now to my knowledge doesn’t have a SINGLE ROADSTER. I made the calculation in my case that, being a full year out of warranty, the car was getting VERY EXPENSIVE to service, and ongoing repair costs would be much more than double what they had been due to the last year’s expenses – due to the slowly deteriorating Power Equipment Module which happens on all Roadsters no matter how lightly driven or charged. The obvious answer is EVERY OTHER Roadster owner quietly did their own cost/benefit analysis.… Read more »

“…those of us who have to PAY for EV’s, something which will never be your concern since you’ll never purchase an EV of any kind.”

Bite me.

Your constant implicit bragging about how rich you are and how many EVs you’ve been able to buy, and your constant attempts to belittle my opinions simply because my interest in EVs is a vicarious one… that’s getting pretty old, Bill. I utterly disagree with your attitude that you are a more important person, and that your opinions are worth more, simply because you’re rich. In fact, the sense of entitlement you constantly express here is obnoxious, and a not-so-subtle case of class warfare. That sort of class warfare is one of the biggest contributors to the growing tribalism in this country.

(continued…)

Pushmi-Pullyu

(…continued)

I’m not reporting merely my personal opinions, but the consensus of opinions expressed by actual Tesla car owners, on the Tesla Motors Club forum and elsewhere. Comparisons by Tesla owners on their annual maintenance costs as compared to gasmobiles in the same price range generally favor Tesla cars. Not always; as I recall there is one brand of gasmobile which consistently ranks lower in yearly costs than Teslae. (Can’t remember which one; is it BMW?)

Your attempts to refute the common wisdom that simplicity coincides with lower maintenance, is downright stupid. Sure, there’s not a 100% correlation there, but the correlation is pretty strong. When it comes to having more dollars than sense, you’re a textbook example.

Pushmi-Pullyu

“….when you go to Drive Electric events or my Canadian Car Club (since I’m in a border state), there are almost no Roadsters being showcased.”

This is typical of your inability to exercise critical thinking, Bill.

It’s pretty obvious that a car of which only ~2450 units were sold, isn’t going to be seen at car meets very often. It’s also pretty obvious that most Roadster owners are not going to want to drive their car long distances, since the Roadster can’t use a DC fast charger, unless the owner gets an aftermarket 3rd-party upgrade. Not even CCS or CHAdeMO, let alone Tesla Superchargers!

The Roadster was aimed at those who wanted an electric “supercar” for an occasional drive for pleasure and/or as a “crowd pleaser”. It wasn’t intended to be a daily driver, nor for driving long distances.

If you had both feet planted in the real world, Bill, you wouldn’t need to have any of this explained to you.

Bill Howland

You are a real embarrassment to the EV owners here, and you constantly violate terms-of-service here.

Other than playing the sycophant to the editors here, why they allow someone who is so unbelievably nasty a person, and who has absolutely nothing to do with electric vehicles other than ride in the rear seat of them maybe once a year is beyond me.

Spider-Dan

I don’t think the Leaf battery degradation issues would strictly fall into the category of “reliability” (unless you’re talking about batteries that degraded to the point of warranty replacement). In my eyes, the loss of a certain amount of range over time is kind of baked into buying a BEV without thermal management, not unlike a sportscar that comes with soft, sticky tires that only last 5000 miles.

Pushmi-Pullyu

An EV’s battery pack is expected to last the lifetime of the car. Tires are not. Your analogy is inappropriate.

The relatively common failure of Leaf battery packs are most certainly a big problem in the reliability department. Not all “reliability” problems are equally important, by a long shot. If one of your Model S door handles quits auto-presenting, you likely can still use the car without any restrictions.

Not so if the Leaf’s battery pack loses so much capacity that it no longer has the range to get you where you’re going.

bro1999

Hey, look at that. The clown car Bolt beats out the competition in another category. 😀

ziv

Mea culpa. But I am only one of many who noted the Bolt’s clown car looks. I don’t think I ever said it WAS a clown car, just that that it looked like one.
I might have also said that it fell out of the ugly tree and hit every ugly branch on the way down. Or that GM hit it with the ugly stick repeatedly.
😉

REXisKing

Looks just like a mini-SUV, one of the best selling categories in US auto sales.
So, if the Bolt is ugly all SUVs are too.

Neil Smith

I would like to see a smaller , cheaper , “city car” version of the EV in mass production for American cities . Something like an electric Smart Car or Fit for about $15,000 .

Prsnep

Won’t happen for at least another 5 years.

Xavierstark

Keep dreaming….

marshall

The statement that there is no water pump that may need replacement is incorrect. Plus, one may need to replace the radiator if it gets damaged, replace radiator hoses and replace the coolant as need or listed in the scheduled maintenance.

u_serious?

Why don’t you wait for 5 years ti do a reliability review. This 1-2 year reliability is just plain Bull$h1t.

Mike

Gotta start somewhere.

Pushmi-Pullyu

I agree. Doing a reliability “comparison” based on a guess as to what a new car’s reliability is going to be nothing but a guess. Reliability ratings should be based on actual surveys of the actual experience of real-world drivers, and only after a year or more has passed since they started driving the car..

In fact, subscribers of Consumer Reports can see that CR’s customer surveys of car owners often contradict what CR’s own auto reviewers guessed about what a new car’s reliability was going to be.

Planned obsolescence

We can talk about reliability after at least ten years of use. It’s not a long time ago that things were manufactured to last a lifetime, now people are amazed when their plastic fantastic product lasts for two years.

Alex

A bit strange to rate best 5 when there are only about 10 EV models in US…

Simone Rambaldi

the Renault Zoe is missing and is by far the most reliable electric car in production

Antonio Briz Ena

Near three years waiting hired battery replacement in my Fluence ZE. 10kwh capacity now. I supose Zoe finish the same. So Renault EVs go to scrap with 5 or 6 years. Thats not reliable at all.

Re-Volted

Sorry but this rating is of nationally available in the US and mostly on initial quality.

Vegan001

It would be at least surprising for EVs not to be more reliable than ICEs. They don’t have thousands of parts that can easily break and are very expensive. Besides the vibrations made by the ICE affect, over time, the quality of the interior, making it noisy.

Pushmi-Pullyu

It’s good to see some discussion of the comparative reliability of the leading EVs, but I’m disappointed to see InsideEVs treat JD Power as an authority. JD Power’s awards are “pay to play”, and their ratings may have more to do with who pays them how much, rather than what cars are actually best.

https://www.consumerreports.org/consumerist/can-you-trust-those-awards-you-see-in-auto-ads/

Dudamus

Shocking survey. So a couple cars have expected Reliability. Thats good. It would help if consumers reviewed other consumer ratings like True Delta dot com and Kelly Blue Book etc. I see several brands being towed more often than others and none of those are Nissan LEAFs. Just saying. I hope all the manufacturers are standing behind their warranties. I’m glad the new Model 3 has a battery degradation warranty. Great news. There are a lot of unhappy Model S and X owners trying to figure out to “defect” their batteries so they can get a new one.

marshall

Which EV has no water pump? I thought they all needed a water pump and radiator to keep the high voltage system parts such as the inverter and traction battery, for those with liquid cooling, from getting too hot.

viriato

Model 3 reliable, with all the issues suffered since it was launched…. lol.

This demostrates, the useless that many of this reports are, when they are made using subjetive answers from users. The reliability can’t be measured by owners, because sometimes the level of fidelity (even devotion) to a maker or model, or the perception of the real dimension of the problems under its point of view, disturbs the reality.

I like the way that german ADAC does its report, based on real road assistances among a year, in a number of millions, considering only cars with relevant registrations and dividing the cars by year of registration. They count how many cars of certain model suffered a problem while were driving, what problem, year and that’s a reliable report about reliability.

The rest, based in surveys, with ridiculous set of data collected and skewed answers are irrelevant for me.

MoMac

It is just the “PREDICTED reliability”, from months ago.

They don’t have sufficient data to give it an actual reliability rating yet.
There are likely other EVs that CR doesn’t have reliability data for and have the same average predicted reliability.

MoMac

I don’t get it. The headline is “Top 5 Most Reliable Electric Cars For 2018”, so I assume the article is referring to the 2018 model year for the cars.
Yet I found an article from the NY Post, dated October 24, 2018 with the headline “Tesla Model S drops sharply in reliability survey.”

The first line states “Tesla’s high-end Model S sedan lost its “recommended” rating and the electric-car maker slid overall by six spots to almost the bottom in Consumer Reports magazine’s annual reliability survey.”

One can find the article be searching for “NY Post Model S reliability”, and there are similar articles from different sources.

So if this is for the 2018 model year, I believe putting the Model S in second place is way way off. I understand that the Model S use to above average CR reliability rating in 2017 and maybe 2016, but not anymore.

And to be clear, regarding the Model 3, it is just a PROJECTED reliability, that they started with a number of months ago. They are still waiting for the data to come in.

Xavierstark

Same on the leaf.
Are you happy now?

Al D

“We all know electric cars are more reliable than gas…”

Actually, they aren’t, at least not yet. There is no EV with a reliability rating topping that of the best Japanese ICE vehicles, including hybrids. According to the unbiased Consumer Reports, not the biased JD Power, the Leaf is more reliable than any Tesla. The BMW i3 is expected to score just average. Ditto for the Bolt.

BillT

To me (and especially) my wife reliably starting and running is the most important part of overall vehicle reliability. BEVs should have an edge over ICE vehicles there. Flat tires now become a bigger stranding risk and I am glad to see GM and Michelin put some effort into solving that issue with the self-sealing tire on the Bolt. Hopefully more effort will be put into solving the tire reliability issue.

wavelet

It’s completely ludicrous to give any kind of reliability score for any car that hasn’t has 10000s of cars at the very least on the roads for at least 5 years. For EVs, that have a single very expensive component (battery pack), that should really be 10 years — aging tests done by the manufacturers can never completely replicate the eventual real-world behavior. (*)
Many issues take a long time (calendar- or mileage-wise) to show up.

All one can really conclude from these “reliability ratings” is that Consumer Reports and JD Power should be ignored.

(*)The fact that this component might still be under warranty is irrelevant — it’s still a hassle to replace and utility degrades long before the warranty threshold is reached.
