problem #1

Jan 232004

(reported on)

Impala 6-cyl

  • 9 miles
There was a bad odor within the cabin of the vehicle. The odor did not occur when the air conditioner was on. The odor made the occupants sick. The cause and location of the odor was unknown although the dealership serviced the vehicle several times. The vehicle vibrated when the brake pedal was depressed. The dealership indicated that it was caused by the rotors being to thin. The odor was caused by a bad fan motor. The dealer replaced the part. The brake rotor problem continued. GM refused to resolve the problem.
