Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was pulling out of a parking lot at about 5 MPH then I thought my engine stalled because I couldn't turn the wheel. It turns out the engine was on, and power steering appeared on the display. I pulled over to see what was wrong. After turning the car off, then on, the problem went away (I think for only a temporary period).”

Coast the car to side of highway sat about 15 mins and restarted car. It started engine light still on but was able to drive fine had about 40 miles to get home and it did it again. I repeated the steps again and drove home. On the next dat took it to the dealership and had it serviced and they said the throttle body just needed cleaning.

NHTSA complaint #10683401, filed 2015-02, 104,256 miles“My 2010 chevy HHR has experienced an ignition issue. The key, when the car is set to park, will not disengage. It remains on, with the only option being to let the car run out of gas/the battery to drain. The key will turn (as if to start the car), and the gear can be shifted from park to reverse, neutral, etc., but will not turn off. All systems stay on, potentially burning out electrical components or causing permanent engine damage. The only way to safely address the immediate issue is to disengage the fuses under the steering wheel, which many consumers may be unable to do.”
NHTSA complaint #10436550, filed 2011-11, 44,000 miles“I went to a meeting and when I parked and tried to turn the car off, it wouldn't let me turn it off. I am a female and didn't know what to do , so I had to call my husband and he came and had to disconnect the battery so it would shut off. Then we had to call a wrecker service and have it towed to a dealership to have it repaired.”
NHTSA complaint #10475482, filed 2012-09“My 2010 HHR has experienced an ignition issue as well. I cannot get the key to turn back to the off position. I got home from work at midnight, put the car in park and when I tried to shut the car off it would not turn back. The only option I had was to pull the ECM fuse and disconnect the battery (or let it run out of gas). The gear shifter will allow me to shift between all gears but it won't turn off. All the electrical stay on, I have only owned this car for 3 months.”
