No check engine light was on, not when vehicle has stalled. My vehicle has had multiple issues. Stalls while moving and at a dead stop. And a scent of burning like a electrical short behind the dashboard. I am afraid that this vehicle could stall while I am on the road and cause me to be rear ended causing a serious crash.

12/23/16, I purchased a 2012 Chevrolet Sonic. 4/6/17, I was at a traffic light when smoke come in the vents from the hood of the car. I called onstar & to run a diagnostic. The diagnostic didn't return any information & I contacted the dealer & took the vehicle for service on 4/9/17. I was told the thermostat housing was leaking and caused the smoking. The coolant system was flushed & filled & a GM oil, lube, filter change was done. The vehicle was ready for pick on 4/19/17. A few weeks later the car was smoking again. I called the dealer, I was told it was probably just fluid on the engine. The car continued to smoke periodically. 6/7/17, there was a large pool of oil under the car, I took the car to a local shop. They said that the oil had been overfilled & that it blew a seal. I called the dealer, I was told they did not overfill the oil & made another service appointment. I was told again there was a problem with the coolant system & the oil & that was the reason for the smoking. Repairs completed 7/10/17. 9/27/17, while driving the check engine light came on, so I called onstar for a diagnostic & they gave me an error code P0299. They told me that it was an airflow problem. I called the dealer & asked for the service manager & gave her the error code. She said there was a problem with the turbo & that I needed to bring the vehicle in. I took the car to them 10/3/17. 10/4/17, the service department called me & told me that the turbo on the car was bad. The repairs were completed on 10/12/17. 10/13/17 the car overheated. The vehicle was leaking coolant in two places. I took it to a different dealer & they said the T-joint in the coolant system was leaking. The repairs were completed on 10/18/17. 11/3/17 an email from on-star said there was an engine problem. I contacted on-star for a diagnostic & they said something is wrong with the coolant system.

- Dallas, TX, USA

Car started misfiring when accelerating and would jerk and be very rough when idling but no engine light. Full tune up found that open valve cover gasket was damaged and that seals were plastic when they should've been rubber, this caused oil to enter the spark plug wells. Changed gasket and seals but problem persisted. Took to the dealership and was told that ignition switch in cylinder 1 was bad, this corrected the issue but now car has burning smell at times.

- Jacksonville, FL, USA

This car has given me so many problems. The radiator, the motor everything.

- Downey, CA, USA

Air intake hose has been replaced due to cracking only 3 years old at that time about 45K miles. Now the shift knob sticks and the button takes forever to release, or I have to pop it back out so I can take the key out otherwise the key gets stuck. Getting worse...now it is becoming harder to shift into park. All these problems occur when stationary...I have not attempted to move the car into other gears while in motion but I know it will happen if it is pushed while that button is not released.

In 2015, my 2012 Chevrolet Sonic had to have the fuel purge valve replaced. The car worked for a while after this. However, a few months ago, it started having a rough idle, with the rpms dipping up and down. The problem got worse recently, when the car actually completely died while making a left hand turn, almost causing me to get hit. Now, it is even worse. Now, in addition to the rough idle, traction control randomly engages even when I am not slipping, causing me to lose all power for brief periods of time, while in motion. The traction control is glitching so bad that it even randomly engages when I am completely stopped. This is a huge safety issue, and the dealership that sold me the car wants $113 just to tell me what is causing it, and how much it will cost to actually fix. There are no active recalls on this vehicle, but further research on the model I own, shows other owners having similar issues. Chevrolet has been no help

- West Jordan, UT, USA

Major concern: My power steering failed. The dealer said the power steering column needed to be replaced ($1,300). The car has high mileage (excess of 150,000). I have had several cars with similar mileage but never had the power steering fail. Since this is electronic steering there doesn't appear to be any warning/no preventative maintenance. Fortunately I was not on the highway at the time this occurred but in the driveway after having driven several hours the same day. We checked for relays in the fuse box but none are marked for the power steering. There were at least two previous times when backing out of my driveway that the power steering locked up but then started working fine. Dealer could not find the problem for the first two incidents. My car has been sitting in my driveway since June 2015 because I didn't feel safe driving if even it was fixed. I've always owned GM vehicles (for 36 years) but the lack of concern about this problem prompted me to purchase a Subaru. At the time of the steering failure I still owed 2 years on my loan. The second problem which I've complained about since the car was new was the transmission. There was always slow response when pulling away from a stop. It worsened after the car had been driven several hours. Again, nothing was diagnosed.
