general problems of the 2000 Chevrolet Impala

Date complaint filed: 03/15/2011 component(s): vehicle speed control date of incident: 03/11/2011 NHTSA id number: 10390238 every once in a while my 2000 Impala with a 3400cc v6 would maintain 50mph with my foot off the gas! the cause is an intermittent malfunction of the tps sensor. It took my Impala 3 years to throw a code and after I replaced the tps, the car's throttle settled down.

Vehicle shuts off while driving. . . Extremely dangerous to drive!! this has happened on multiple occasions.

My car started to over heat in the middle of winter in minnesota. There was plenty of coolant in the reservoirs. While the vehicle was idling there was a noise and once I started to move again the car began to jerk then the check engine light came on while attempting to accelerate. Then a few weeks later the gas gauge began showing the incorrect about of gas levels in my vehicle.

2000 Chevrolet Impala. Consumer states vehicle accelerates by itself. The consumer was involved in an accident, during a rain storm. The vehicle hydroplaned/fish-tailed in the road. The consumer struck a tree and flipped over. The air bags never deployed. The consumer suffered minor injuries.

I drove around the rear of my home which is where my garage is located. I came to a complete stop. I activated my garage opener from my vehicle. Once the garage door completed opened I took my foot off the brake pedal and all of a sudden my car accelerated to a high speed. I could not stop the car. The car jumped a 9 inch ledge and I crashed through my garage wall, and into my basement and the car finally stopped in my basement when it hit my computer desk.

I was driving into the parking lot of my place of employment. I was going slowly and all of a sudden the car accelerated to a high rate of speed and, I could not stop. I crashed into a cyclone fence, 2 central a/c units, went down a hill and nearly crashed into 2 poles . I finally stopped the car by holding the brakes and shutting the car off.

When attempted to stop on incline hill, and let brake pedal go, vehicle rolled backward without a prior warning. Consumer was concerned about it. Please consumer provide more information.

Car rolls backward when engine running and foot taken off brake to go forward. Requires the brake to remain engaged and gas pedal pressed at same time. My roll backward if not done with using both feet. It's an automatic car transmission. Dealers deny this is a problem and refuse to correct it. Please help.

Vehicle rolls forward and backward after coming to a stop when foot comes off brakes before consumer gives gas.

Engine falters,falls flat for approx 7 seconds pulling into traffic. Temp=72 deg, hum= 85%. Fully warmed car parked 1hr+15min. Restarted,ran fine 15 sec. , major hesitation when throttle applied,finally came to life after 7 sec. And near-miss pulling into traffic flow. Third occur in 30 days. Warm engine + one hr. Park + 85% rh. Are factors.

Our Impala has had a problem where it hesitates and stumbles when you try and accelerate since it was new. The dealer has not been able to identify the cause. This a hazard! I think we should get our money back but they keep giving us the run around "you bought and now it's yours". I think that stinks! I see other complaints concerning this problem on your web site, can't you guys contact gm and demand they do something about this?.

Car keeps rolling back at idle sitting at light,took car in asst. Service manager told me tgere had been a # of complaints about the same thing,nothing they can do. Gave me a 1-800-222-1020# to call explained this to them was told they had not heard anything about this either and gave me a file# and was told to keep in touch with asst. Service manger. I feel this is a saftey issue if stoped at a light and another car is on my bumper if I roll into them it could cause a real problem. Thank you in advance for looking into this matter. Dianne topping.
