What owners wrote

About march 1, 2005, steering mechanism would vibrate and lose control. Front brakes would pull the car to the right. A subsequent motor vehicle accident occurred on february 7, 2005, on I80, 7pm, going southbound. Luckily no one was injured in either car ... My car was hydroplaning due to inclement weather conditions.

February 2005 CrashInjury

I was pulling my 1999 pontiac grand am out of my driveway when the car was making a strange scraping noise. I looked under the car and did not see anything touching the ground. I did not drive the car. My husband checked it out and pulled the car out of the driveway. The wheel popped as he was doing this. The car was in the middle of the street so he had to pull it forward. The tire was shredded. After jacking up the car, he saw that the spring was broken and was poking into the tire.
