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 Pontiac Bonneville Owner Comments

problem #3

Nov 272016

I have replaced an arm, tie rods, stabilizer bar, had an alignment, new tires, sway bar, and bushings. Still shaking more than before.

problem #2

Bonneville LX 4.0L

  • Automatic transmission
  • 100,000 miles

Just thought I'd mention that I did have some vibration in steering a couple years ago and needed tie rod ends replaced. Fairly easily resolved issue. I have not had any serious issue with this car to speak of since I bought it in 07. Served me well. High miles will take toll now probably.

problem #1

Nov 082010

Bonneville SE 3.8L

  • Automatic transmission
  • 180,000 miles

Vehicle vibrates mainly at slower speeds or when you accelerate. Replaced drive axles and now am told it needs tune up and could possibly be transmission. Other people I know who have had a car like this or knew of someone who did said they all had the same problem and couldn't find a fix for it. Is it a factory flaw or was this just a bad year for the bonneville?
