NHTSA Complaint #11448633 — 2017 CHEVROLET VOLT

BECM (Battery Control Module part # (24296900)) on my 2017 Chevrolet Volt failed. When the failure occurred the instrument display showed a “Propulsion Reduced” warning. At the same time the engine started (the traction battery was fully charged at the time) and the check engine light came on. I subsequently received an email from General Motors that they had detected a lithium ion battery problem with the car and to have it serviced within 7 days. The GM dealer subsequently diagnosed the issue as a failure of the BECM module. Although an online search of this issue shows that there have been hundreds of failures of this module there are no replacement parts currently available. The car has been sitting at the dealer for several weeks with no estimate of when a replacement part will be available. The dealer has recommended not driving the car until it is repaired. I was able to drive it to the dealer on electrical power after the failure occurred.
