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.
Intermittently, the car would not turn off, starting in about July, 2022. After shifting the car into park and pressing the On/Off switch, the car displayed a message like "Action required. Shift to park". It was impossible to know if the car really was not in park, and would roll into someone, and it was certainly unsafe to walk away and leave the car "on". A Chevy forum showed that this problem is COMMON and pointed me to GM TSB 19-NA-206 (https://static.nhtsa.gov/odi/tsbs/2020/MC-10171895-9999.pdf). The TSB exactly describes the symptom I observed and lists one of the exact parts that the Huston Chevrolet service department replaced on 8/3/2022 - 84733196 N-Harness. The dealer, Chevrolet customer service, and GM customer service all told me that this repair was not covered under warranty, though the TSB says this on page 4: "Specific to the Volt model, repairs are covered under the Voltec (Electric and Hybrid Vehicle) Warranty." GM said that I would have received a letter if the TSB applies to my specific car. I paid Huston Chevrolet $446.79 to repair this problem, and believe the manufacturer should 1) reimburse me for the cost and 2) notify other owners about this common and dangerous manufacturing defect.
About half the time, when I put the vehicle into park, a warning comes up telling me that the vehicle is not in park. I can make the problem go away by wiggling the shift lever. But it is a recurring problem, and it is getting worse.
Vehicle displays error message "shift to park" while vehicle seems to be in park, resulting in a situation in which the vehicle will remain running and energized after driver thinks they have put the vehicle in park, turned it off, and exited.
