This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
When attempting to power down the car, a message, -??Action required, Shift to Park-?? appears and car will not power down. After repeated attempts, sometimes requiring 10 or more, by re-starting the car and attempting to power down, it has eventually powered down. This problem is intermittent and the car WILL power down successfully repeated times, and then do it-??s -??shift to park-?? refusal to power down. There are hundreds of complaints on the GM Volt owners-?? forum and even a Technical Service Bulletin No. 19-NA-206 dated February 2020 (maybe even more recent, but that-??s the latest one I know of). The service bulletin also includes the Chevy Blazer, Malibu, Traverse and GMC Acadia (which, I understand, there is now a class action suit in that regard). If the car will not power down, it could drain the battery and leave the driver stranded, as well as making the car unable to be locked, which could also be a safety issue.
