No place to pull off the road. I placed the car in park and turn the key to off and restarted. The engine light came on and the message displayed was engine power reduction. I drove 20 to 25 miles per hour to my destination the car would only go 30 miles per hour and the car shifted roughly and jumped. A nice guy there, turned the key to the on position 3 times before the engine light would go off. …”
NHTSA complaint #10577892, filed 2014-04, 80,370 miles“Approximately 6 weeks ago, I was driving my Chevrolet HHR 2007, (40 MPH), when traction control light came on, and the info showed traction control off, and then service traction, at the same time I could hear and feel the car was shifting hard.

NHTSA complaint #10650167, filed 2014-10, 58,400 miles“My clutch went out and the car stopped working gas I was driving along the highway. It was not during a shift, just acceleration. The clutch did the exact same thing on december 23, 2013 (mileage about 115,000). I have driven manual transmissions previously and have gone well over 100k miles without replacing the clutch and I am now on my 3rd clutch. I know there is a TSB on a possible bad flywheel (which was not replaced either time), but a clutch to go out twice on a car that has seen for the last 55k almost all highway miles indicates there is a problem with the car.”
NHTSA complaint #10559616, filed 2014-01, 62,373 miles“While traveling on an interstate hwy, at approx, 65 to 70 MPH I felt the car pull hard to the right, after going into a spin , it became hard to apply brakes and to try to correct or control the spin , there were vehicles including a semi all around my car. As I slid off the traveled portion of the hwy. My car impacted the wall head on. I was slammed into the dash . A moment later I calmed down and thought to myself why didn't the airbags deploy? I hit the wall at least at 35 MPH, then I saw the car was not running, I saw the key had moved to off, I started the car and drove home.”
