“While driving on a wet road at 30 to 35 miles per hour. The car shuts off when I topped a small hill and I lost all power. 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. …”

It was like kicking. I parked, turned off the car and turned on again, and the light disappear but after few hours, it was there again, shortly after the engine light came on with the info check engine, and stayed on with the traction control light, then this disappear but the engine light stayed. …”

“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.”

“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.”
