GM Upgrading 2013 Volt Software to Prevent Shutdowns

5 years ago by Lyle Dennis 3

The Chevrolet Volt was considered GMs automotive answer to Apples iPhone.  It is a car packed with technology, and like gadgets, has the ability to receive software updates.

Inside the Volt, there is are processors running on more than a million lines of computer code that control everything from dashboard behavior and battery monitoring to electric motor operation.

GM has discovered that there is a glitch in the software found in the 2013 Chevrolet Volts.

This discovery came through the site I founded, GM-Volt.com, where forum members first reported their cars were mysteriously shutting off while driving with the steering wheel and brakes still functioning.

GM determined a software glitch could cause the electric motor to power off only if the car is running with the delayed charging function activated.

This problem affects 4000 vehicles only of the 2013 model year and GM has FedEx’d a letter to all those owners notifying them of their need to update.

We are notifying 2013 model year Chevy Volt owners about a customer satisfaction issue. We have received a few reports from owners that their electric motor has temporarily stopped working, resulting from a software anomaly when their vehicle is in the delayed time and rate charge mode,” GM spokesperson Michele Malko told reporters. “We’re asking owners to bring their vehicles into their local Chevy dealer for a re-flash of the vehicle’s control system, which should take less than an hour. Until then, we’re recommending that customers switch to immediate instead of delayed time charging to avoid this inconvenience.”

    I’m glad that GM is pro-actively updating their software when bugs are found. These car companies really should have full-time software engineers devoted to testing and upgrading their software. As a stark contrast, I have been begging Honda for years for a software upgrade to my 2010 Insight. I have pretty much given up hope that they will make any effort to support their existing customers. Which I guess is ok because I will probably never be a Honda customer again…

    In time, I’m sure that all companies will release periodic updates and patches to their software. In the meantime, the consumer is often left frustrated and wanting…

      GM does not have a choice, they have to fix this. However there are bugs and deficiencies that are considered secondary and unimportant that may never see a fix. It boils down to the cost of fixing the bug versus the perceived benefit and the people making this determination do not necessarily have the customer’s needs in mind. The interesting thing is that this mismatch goes the other way as well. The battery tunnel structural enhancement is a good example of that.

    GM is artfully handling this issue. It beckons how issues such as this one will be handled in the future. Why not speedily offer software updates before the hair-trigger media latches onto
    a “recall”?

    While GM is carefully navigating this particular glitch, it could be said that they’re trying to avoid the above with the quick FedExs. I’d beg to differ – since the 2013 Volts effected
    can still continue to operate normally when switched to immediate charing mode – and they
    still can continue to perform transportation duties to their owners in CS mode until they can
    be brought into the dealer for the reflash.
