Brake Grinding Noise problems of the 2003 Chevrolet Impala

The traction active light lights up after backing up and braking. I understand this is a known problem with Impalas. The car makes a grinding noise for a second or two. This is an intermittent problem.

The contact owns a 2003 Chevrolet Impala. While parked the contact noticed the abs, check traction system and trac off warning light illuminated on the instrument panel. There was also a grinding noise while driving. The vehicle was taken to an independent mechanic for diagnostic. The mechanic stated the front passenger side hub bearing assembly would have to be replaced. After the repair the warning lights continued to illuminate. The vehicle was taken back to the mechanic. The front drivers side hub assembly was replaced. The light continued to illuminate after the repair. The vehicle was taken to the mechanic a third time. The mechanic was unable to diagnose the failure. The vehicle was not repaired. The approximate failure mileage was 112,878. Kmj.

Consumer heard a grinding noise which sounded like metal to metal. The consumer made an appointment with the dealer, but the dealer was not able to get the consumers vehicle in for inspection. Consumer took vehicle to jims mufflers to get the brakes fixed. The mechanic took off all four tires and showed the consumer that he needed to replace front and back rotors and pads. The mechanic the cleaned calipers. The consumer spent about $500. 00 for repairs. When the dealer looked at the brakes he stated that they looked as if they had sat in water. Consumer claimed that vehicle had not been in water. The mechanic stated that maybe the rotors or calipers were contaminated because brakes should not have looked that bad for the miles on the vehicle. The mechanic determined calipers may not have been working properly since the rotors were so rusty.

Refer to the gm recall on 800,000 vehicles due corrosion affects antilock brake system. I own a chevy Impala 2003 4dr sdn v6 fwd w/antilock brakes and aws. The system failed much like in the above stated recall last winter in michigan. While approaching a stop sign, upon attempting slow the vehicle using the brake system it failed doing just the opposite of what it was designed to do. There were grinding noises, vehicle pulling to one side, loss of control, vehicle took over. This happened at low speeds under 5 mph. The loss of control due system failure resulted in said vehicle ending up in a 70 foot ditch whereupon it had to be towed out of. Damage was sustained to the front left fender, bumper and driving light.
