| While on a medium downgrade on hwy 101 in marin county, ca at approx 65 mph i slowly applied brakes to reduce speed. the brakes immediately started to chatter and i thought the abs system was activating. i continued to just tap on the brakes to keep my speed reducing to the legal limit (55 mph) and the chattering stopped when speed was reduced and i was back on level grade. the condition has not repeated itself when driving on a level grade and with normal braking when slowing down from 65 mph. in august 2012 i took the car to a dealer for a minor warranty repair and asked them to also check the brakes for any problem with the abs system - still thinking that is what caused the initial problem. i was told that the brake rotors were warped and was caused by the way i drive. i have been driving for over 60 yrs and have never had this type of brake problem. this car was purchased new in nov 2009 and it has been driven less than 10k miles per year - it is still under warranty until 11/2012. gm refuses to accept any responsibility for premature rotor warping or that their brake design maybe faulty, i.e. inadequate cooling for brakes, etc. they were of absolutely no help in addressing this problem seeking to put any blame solely on the driver. how can one respond to that kind of attitude. the nhtsa should make gm certify that their brake system, materials, brake cooling design, etc. could not possible cause any form of brake rotor warping in a vehicle driven less that 25k miles. thank you for looking into this matter. *tr | |||

| I own a 2010 chevy impala on a short trip to shankville, pa. as i tried to slow down by tapping the brakes and the vehicle began to shake and pulsate violently. this happened again as i was taking my wife to the airport. the vehicle will begin to shake violantly when i apply the brakes at around 60 to 65 mph. i took the vehicle to the dealership and was told that the rotors are warped, and i should get new brakes with new rotors. i informed the individual that the vehicle had just had its yearly state inspection done by them in march of 2012 this was early august 2012 and the vehicle had only been driven less then 2000 miles. a check on the internet shows that the impla is prone to warped brake rotors. this is a serious saftey issue. *tr | |||

| I had purchased a 2010 chevrolet impala in july, 2010. the first attempt at repair of the front end vibration was on 10/22/2010. the dealership did not recognize the vibration. the vehicle tires were rotated on 01/26/11 in an attempt to stop the vibration in the front end. the vehicle was taken in on 03/18/11 for front end noise (thump) while turning the wheels. the vehicle was taken in on 07/07/11 for the thumping noise in the front end while turning the wheels. the vehicle was taken in on 07/28/11 for a front end thumping noise when turning the wheels. the vehicle was taken in on 08/16/11 for a front end thumping noise and the dealership notices the tires were wearing slightly cupped on the inside edge. the vehicle was taken in on 09/08/11 for a whining noise from tne engine bay and power steering fluid was flushed. the vehicle was taken in on 04/09/12 for front end thumping noise, wheel bearing, transmission surge, and whine noise from radio. the vehicle was taken in on 06/27/12 for rough idle, tire replacement, transmission. the vehicle was taken in on 07/27/12 for rough idle, transmission surge, thump noise in front end and whine noise in radio. the vehicle was taken in on 10/05/12 for transmission surge, rough idle, thump noise in front end, and whine noise in radio. the outcome at this point is the dealership tried to reprogram the vehicle, gm approved replacement of all four tires, a replacement of the power steering pump, wheel bearing on driver front side. the dealerships have done two throttle body cleanings. the dealership has stated they will replace the rotors but gm would not approve replacement only turning on the rotors. this case has been opend with the better business bureau whom advised me to contact nhtsa. gm refuses to replace parts because their computer system cannot tell them what is wrong with the vehicle. gm has recalled the police vehicles for front end suspension and has a lawsuit pending in michigan for personal vehicl | |||
