Tesla Issues Recall For Certain Charging Adapters Due To Overheating / Potential For Fire


Tesla Motors has issued a voluntary recall of 7,000 charging adapters.

The recall comes after two Tesla owners reported overheating of the affected adapters back in November.

According to Bloomberg:

“Two customers reported overheating in November, according to an e-mail the company sent to customers Tuesday. No damage besides the melted plastic was reported, and Tesla said it has notified U.S. regulators of its voluntary recall. The accessories were manufactured by an outside supplier and haven’t been sold for at least six months, according to Tesla.”

Both cases involved the NEMA 14-30 adapter, which is typically used to charge a Tesla via a clothes dryer plug in the U.S. Tesla says international owners are not affected by this recall.

The NEMA 14-30, as well as the NEMA 10-30 and NEMA 6-50 adapters are all being recalled. replacements adapters are being designed now and will ship out in a few weeks (14-30) to a few months (10-30 and 6-50). In the menatime, Tesla urges owners not to use the affected 14-30 adapters, but says the other two affected adapters may continue to be used.

Tesla issued this statement on the matter:

NEMA 14-30, 10-30, 6-50 ADAPTER RECALL

Because safety is our top priority at Tesla, we want to inform you of an action we’re voluntarily taking to recall a small number of charging adapters.

This recall does not involve the Tesla Wall Connector, Universal Mobile Connector, NEMA 14-50 adapter, or NEMA 5-15 adapter that came standard with your Tesla and that most of our customers use for charging. It only involves NEMA 14-30, 10-30, and 6-50 adapters, which are sold separately as accessories and which are used by relatively few of our customers.

In November 2016, we learned about two customers whose NEMA 14-30 charging adapters overheated. These are the only two such incidents that we know of anywhere in the world and neither resulted in any injuries or property damage. However, out of an abundance of caution, we’re replacing NEMA 14-30, 10-30 and 6-50 adapters that were made years ago by our original supplier.

If you have one of these NEMA 14-30 adapters and regularly use it, you will receive a replacement from us within the next couple of weeks. If you do not regularly use it you will receive a replacement as soon as possible. Until then, we ask that you stop using your current adapter, and that you instead charge your car in a different way, such as with a Tesla Wall Connector or NEMA 14-50 adapter (if you have one), or by Supercharging.

Although there have been no incidents with NEMA 10-30 or 6-50 adapters, they have some common elements with the NEMA 14-30, so we will be replacing those as well. These replacements will take about three months to develop and manufacture. In the meantime, since none of these adapters has ever overheated, you can continue to use them if you do not have another way to charge your car.

If you need additional assistance, you can also contact us by phone at 877-798-3752 or by email at ServiceHelpNA@teslamotors.com.

How to determine if your adapter is affected by the recall
Your adapter will likely be included in the recall if you purchased it more than six months ago. To check, compare the part number on the prong side of the adapter to the table below. If you find a match, your adapter will be replaced.

Recalled AdapterPart Number
NEMA 6-501016021-00-A
NEMA 6-501016021-00-B
NEMA 10-301016174-00-B
NEMA 14-301018243-00-A
NEMA 14-301018243-00-B

The latest version of the NEMA 14-30 adapter does not need to be replaced. They have part number 1018243-00-C and have a gray plastic cap (on the right in the photo), rather than a black plastic cap (on the left in the photo).

Are any of the standard equipment adapters affected?
No, only 14-30, 10-30 or 6-50 accessory adapters purchased separately are impacted by this recall. The 14-50 and 5-15 adapters included with your Tesla are not affected.

When will I receive my replacement adapter?
Replacement 14-30 adapters for those who regularly use them will be shipped to the address we have on file within the next couple weeks. Replacement 10-30 and 6-50 adapters will be shipped to the address we have on file in about three months. Please verify your address by signing in to your account.

May I exchange my adapter at a store or service center?
Replacement adapters will be mailed to your home. We will not carry replacement adapters in our stores and service centers until after the recall is complete.

Are the adapters made by Tesla?
The adapters were designed by Tesla and produced by a supplier.

What will Tesla do with the old adapters?

Interesting. This overheating problem has been reported in these very comment sections for nearly a year.

They have already done this once…

Yeah, I think about 2 years ago they did a ‘recall’. Although it was actually just a software update from what I understand to better regulate voltage or turn it off it gets too hot? Something along those lines.

These are being actually physically recalled this time, so I guess a software fix could not correct whatever was wrong.

That’s good they took concerns seriously – always better to recall an item before a major issue occurs.

If you have one of our JESLA’s, please get this done.

Yeah, these things are junk – no surprise to me they are having issues.

The former overheating problem addressed the 14-50 model – by lowering the current if necessary, and more importantly, having a fusible link to shut off the juice on the ‘fixed’ models.

I fully expected trouble on the 40 amp 6-50 (no fuse modification yet), but I’m very surprised the 24 amp units are overheating… They must be even junkier than I imagined.

These aren’t built by Tesla, of course. They are built by Jabil in Mexico.

There’s no “fuseable link”. Power is reduced by monitoring changes in the frequency of the 60hz AC power.

One problem (of several) that I have identified is poor welding of the conductors to the pins.

That can heat up at any amperage.
