Notes: The 2012 Chevrolet Sonic is fairly new & is already showing an early trend of transmission problems.

Owners report hesitation when shifting & grinding/hard shifting into gears. Some dealers are calling the condition "normal". Another owner reported his dealership replaced the transmission under warranty, but the new transmission had the same exact grinding problem. Design defect?


definitely annoying

The button on the gear shift sticks. When the button won't pop out after being put into gear, it can be bumped and moved into another gear causing a safety risk. The gear shift should be recalled! also when I'm in park and it won't pop out, my car will not let me remove the keys. And when the keys are in the ignition, the car won't lock. My car is also now likely to be stolen.

For an automatic 2012 Chevy Sonic. Gear shift knob became nonfunctional causing key to become stick in ignition. Could not exit vehicle. Could not shift into D or sometime out of drive into park. Eventually went to the dealer who replaced the whole unit at a charge to me. The replacement unit seems to occasionally stick in the same way however has not caused problems yet.

I noticed the button on my gear shift would always stick when I either went to put the car into gear or into park. I could not shut the car completely off until I got the button unstuck. Then, I noticed that the button was broke. This would happen anytime I used the button. It had been sticking on me for a while, but I noticed it was broke on 6/9/2016.

When changing the gear selection for example from park to drive....the gear button stays stuck / pushed in..... this is dangerous as an infant or your passenger can accidentally hit the shift knob allowing the car to come a sudden stop or put the car in reverse.

Check engine light-------after the factory warrantee expired I still have the power train in full force, but the check engine light keeps coming on. I had it repaired about 8 months ago for some part covered under power train. This makes 6 times the engine light has come on again. I hate this because I cannot use the main feature I purchased the car for auto start. So needless to say it is doing the same mess....

I have an automatic car. When I put the car in park, I believe its called the gear shift button, gets stuck for several minutes and I cannot remove my key from the ignition until it pops out. Reported this to my dealership and they spayed some oil around the button but that did not help. This happens daily. Sometimes it takes a few seconds for the button to pop and other times it has taken up to 10 minutes for the button to release.

This vehicle has had "undiagnosable" problems aince it hit 1200 miles. I have made 57 visits to Chevy dealerships for attempted diagnostics and repairs. The car has lurched forward of its own Accord, my brakes have failed to engage on a single occasion, the car has intermittently shut off during idle, the car has also had issues with shifting for the last 2 years. A 3 year battle has yeilded no answers or improvement; I was unable to utilize the lemon law because the issues couldn't be diagnosed. Finally the car is showing codes for what I believe is the transmission based on how poorly the car is running. I can provide information for the dealerships I have worked with; they have all the documentation for the obscene number of visits I've made with this car.

My radio will turn itself on hours after my car has been turned off. I've had to take out the fuse everytime I exit the car so the battery won't drain. I don't know where to begin with fixing this problem. It's been going on for a few weeks now. I've called to the dealership where the car was purchased and they said it was a manufacturing problem. Please don't tell me I have to pay for this out of pocket. From what I've seen there's a lot of these cases on the internet. So it's not just a random problem.
