During the last week had problems with the key not releasing from steering column. The last two days gear shifter getting very hard to shift and button sticks and key will not release, and wheels will not lock. Have had to leave the key in car which is not a very safe thing to do. Have noticed today that the button after awhile will pop out and then the key will release. This is a safety issue and needs to be recalled before things get worse which apparently is going to happen..

Sonic 4-cyl

  • 45,000 miles
I have a 2012 Chevy Sonic lt automatic with the 1.8 liter. The car started having problems around 45,000 miles and has gotten worse over time.the car on cold start ups has a grinding sound. This grinding most of the time only happens on cold start ups but does at times happens on warm start ups. This sounds like metal against metal and it rattles. This seems to happen until the car is fully started and running. I am getting concerned because it is getting worse and louder.
