The contact stated the wheel sensors stopped working, causing ABS failure. When applying the brakes there was a grinding noise and the brakes would not stop the vehicle. The dealer replaced the wheel sensors, reset the codes, replaced the right and left rear wheel bearing assembly, and resurfaced all four rotors on the vehicle. The repair seemed to have corrected the problem. In addition, while turning the steering wheel there is a clanking noise. Technical service bulletin 04-02-35-0048 dealt with the steering problem. However, this problem has not been corrected.
2001 Chevrolet Impala. At 6,500 miles the consumer noticed the brakes grinding. The vehicle was taken into the dealership on July 7, 2003, and she was told it was a normal metallic pad noise, and there was no correction necessary. There have been no corrections to this vehicle at all. The consumer's son recently drove the vehicle and noticed the problem himself. Also, while driving the steering wheel wobbled. The consumer contacted Chevrolet, and they recommend the vehicle be taken back to the dealership.
While applying the accelerator pedal vehicle vibrated uncontrollably. Consumer was able to maintain control of the vehicle, and drove it to the dealer for inspection. Mechanic determined that the front rotors needed to be resurfaced, and resurface them. At 21,222 miles the problem recurred, and the front/rear rotors were resurfaced. At 29,776 the problem recurred, and the front rotors were replaced, and the rear rotors were resurfaced. However, the problem recurred. The front brake pad on the drivers side fell from backing rendering the front brake useless. GM stated that front brake pads were not covered after 12000 miles. The consumer stated that he would like GM to cover at least 50% of cost. After 4 incidents of warped rotors the pads fell apart.
Our 2001 Chevy Impala has had brake and rotor problems since the car had approximately 15,000 miles. The rotors were cut twice and replaced once while under warranty. The car pulsates when reducing speed and the steering wheel shakes when braking. We just spent $1,449 at the local Chevy dealer to have the rotors once again replaced and brakes replaced along with the ABS braking system. It is no longer under warranty as the vehicle has 65,000 miles. There is no reason brake rotors should have to be cut or replaced every 6,000 miles. There is no reason that the brakes should have had to be replaced twice. There has to be a manufacturers design defect and the car manufacturer should have to pay for all these expenses.
Car was vibrating when breaks applied especially at speeds over 45 mph. Problem with rotors being warped, wrinkled and wavy according to dealer service. Had to have front rotors replaced at 17,000 miles on Aug 6th 2002. On May 23rd 2003 had to have front rotors and rear rotors replaced again at 28,000 miles. Car is beginning to vibrate again mileage is $42,000. I feel that there is a problem with this car and shouldn't have to have the rotors replaced every few thousand miles.

I own a 2001 Chevrolet Impala ls. This is the second time I have had to replace the front rotors. The first time the vehicle only had 20,000 miles and now I am replacing them again 1 year later with only 46,000 miles on the vehicle. I have used both GM rotors and another manufacturer and both rotors warped very prematurely. I have read numerous other complaints on this site regarding the same exact problems. I also experience severe vibrations when braking at speeds of greater than 45 mph. It is not normal car maintenance to have to replace front rotors every 20, 000 miles. I believe there must be a design flaw or some other event causing this scenario.
My 2001 chevorlet Impala has experienced problems with the rotors wearing very early. New rotors wore out after only 7,000 miles. After being "fixed" by 2 different mechanics, the car continues to experience "shaking of the steering wheel" when the brake is applied. The vehicle also has a tendency to "slide" very easy on turns when the roads are wet. Both mechanics indicated that the brakes were repaired but the underlying problem has yet to be identified. On wet roads, this is clearly a hazard.
Vehicle vibrated and shook at high speed (above 50mph) when brakes were applied. Scraping noises were also heard. Dealer would only look at brakes if diagnostic fee was paid. Result was that rotors were warped on the front of the vehicle and pitted and scored on the rear of the vehicle. Vehicle has 18K for mileage. Brake pads on both front and rear had 75% wear remaining. Front rotors were turned and pads replaced. Rear rotors and pads were replaced.oem design of rear pads has a vertical groove in the middle which collects dust, dirt and debri contributing to the wear issue. Replacement pads do not.
The consumer stated that while driving at any speed and with no warning, the brake rotors woe out and caused extended stopping distance. The dealer was notified. There was a pulsation when the bakes were applied.
The brake rotors were warped which caused vibration while braking. The vehicle was taken to the dealer who stated that the rotors were warped because the vehicle wasn't used enough. The dealer refaced both brake rotors.
Transmission went out, have to be completely rebuilt. Metal pieces were found in fluid. Vehicle previously in for service due to the pressure modulator in transmission went out. Felt like you were driving and shifting without a clutch if the car was a stick shift. Prior to that, the computer module went out, causing the battery to drain over night and having to jump start it. Before that, the automatic traction control system went out. Found out it was a faulty sensor in the back brake area. Before that, the front rotors were severely wrapped and had to be replaced.
Getting rumbling feel when applying brakes, especially bad at higher speeds. Dealer replaced all 4 rotors. My concern is the repair order stated "warped rotors" when if fact the service manager stated the rotors were pitted, not warped. I was concerned beacuse I was very conscientious to make sure every time the tires were rotated and balanced the wheels were torqued to the designed ft lbs. I have checked with several other dealers and garages they tell me they have replaced many GM rotors for the same problem of premature failure (pitting). Normally with warpped rotors you get a vibration and surging at low speeds when applying brakes, I did not have that. I had rumbling at 25 mph and higher, especially bad when hard breaking between 55 & 65 mph.
There is this vibrating feeling that only happens when the brakes are being applied at any speeds. Contacted dealer, and the dealer replaced rotors on vehicle.
