NHTSA Complaint #11477470 — 2017 CHEVROLET VOLT

When attempting to engage the vehicles drive system, it would occasionally fail to recognize the propulsion system battery. This could potentially leave someone stranded in dangerously high or low temperature environments without food or water. Powering off the vehicle and then powering the vehicle back on would sometimes fix the issue. The issue occurred very randomly and was unable to be reproduced once working again. It would continue to happen more frequently and require more tinkering to get it working until almost complete failure. This appears to be a common issue and found to be the result of a failed BECM (battery energy control module). It triggers the check engine light and a series of trouble codes. It is estimated that the replacement of this module takes roughly five hours. Unfortunately, supply chain issues have recently resulted in owners being without their vehicle for multiple months with no loaner vehicles available and no additional compensation.
