Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Chevrolet Impala Owner Comments

Impala 6-cyl

  • Automatic transmission
  • 117,000 miles


I have a 2003 Chevrolet Impala that keeps showing a service traction system alarm. When this occurs the anti lock brakes shut off. I have checked the codes and none show. Have been told that it could be in the wiring harness or the front wheel bearing on either or both sides.

Impala 6-cyl

  • Automatic transmission

Our 2003 Impala ls @ 50K miles had a vibration when the brakes were applied that greatly increased with harder braking and also a steady vibration from the front end that increased as speed increased. My retired father in law brought the car to the dealer where we purchased the car, brian harris Chevrolet in baton rouge, la and he felt that he was treated poorly by the service dept. We then took the car to all star Chevrolet where we were treated professionally. They diagnosed the problems, front wheel bearings and warped rotors, but said that they could not repair it under warranty until it was approved by the warranty carrier, which could take several days. They said that rental car reimbursement would be made if warranty repair was approved. We paid a diagnostic fee and picked up our car and then took it to our local independent repair shop that we have dealt with for years and paid for the repair ourselves. They resurfaced the brake rotor and replaced the left front hub assembly. Now @ 80K miles we are experiencing the same warped rotor problems again.
