The car shows a message on the instrument cluster that says shift to park even though the gear shift lever is already in park. This failure to detect when the gear shift lever is moved to park prevents the car from shutting off and locking. Sometimes continuously wiggling the gear shift and repeatedly shifting to other gear positions and back to park can sometimes get the vehicle to recognize it is in park. This situation occurs intermittently without a pattern. Very frustrating. And dangerous.

This vehicle has a shift to park message that been seen on many GM vehicles. Some of the owner sites I have been to say that this is covered under warranty. I have not been so lucky with GM. The dealer did cover 1 repair of this problem but now says I have to pay. The problem has returned and persists. A shift to park message is displayed on the dash after the car is in park and will not shutdown. I have attached all the documentation that I have.

Warning about airbag system not working correctly and told to bring car to dealer within 1 day. Car was in motion on city street with my son in front. I don't know exact parts but I brought it to Chevy and they refused to pay for fix (so the car is still there while I appeal). It was something about the system in the seat and possibly dash that controls the airbag.

All vehicle systems are not registering that the vehicle is in park when the shifter is in the park position.

When exiting the vehicle the doors will not lock.

When vehicle is shifted into park position and engine in powered off, the dash reads out that vehicle must be in park position. I have to jiggle the shifter or depress the button several times to engage into park position. If this is ignored the vehicle does not register in park and cannot safely be left unattended. This occurrence has been happening for over a month at a daily rate. The dealership does not honor the power train warranty for this issue.

2016 Chevy Volt wouldn't start, less than a year old, current on maintenance. Towed it to dealer, they said there were some recalls - but couldn't tell me what was wrong. Got it back after 2 days, was fine - then on 9/22/16 wouldn't start again - I was stranded in the dark, got it jump started. Took it to the dealer, since it was running fine he didn't take it in. Told me next time it happens to get it towed in. Wouldn't start again yesterday, unreliable car. Please investigate.
