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.

2001 GMC Sonoma Owner Comments

problem #2

Sonoma 4WD 6-cyl

  • 55,000 miles


The foot operated parking brake broke under normal wear and tear. I had estimates that were well over $300 to fix, and have not yet had work done. I only park on level roads and hope transmission will hold in park. I feel this must be a defective part.

My truck radiator started to smell as if it had a leak. I took it to a radiator shop. This shop happens to be very close to the GM plant in dayton, Ohio. The man took one look at the truck. He explained to me that all the radiators for this truck from the 2001 years were sent to him prior to installing. He said they had been left outside for a period of time and all of them had to be cleaned out because of heavy rust. He stated mine must of been missed. The rust in the radiator was so thick it was like mud! he replaced the radiator, hoses and even had to replace the radiator fluid reservoir because it literally had inches of rust in it. This is something the company knew about and I should not of had to replace it. The next thing to happen is to the drive train. The truck is making a whining noise - sounds like some tires do. We have taken it to several places to repair and no one can figure out what is causing the sound. We have replaced so many parts, many of them more than once in a short period of time. I have put over $3000 of work in the truck just over the last month and am not yet finished. The brackets holding the rear suspension in place are crumbling in my hand. The muffler is leaking. It is stalling for no apparent reason. And is idling very fast even tho it has had regular tune ups and maintenance. The tailgate is broken - you can just pull it off the truck. This is not normal wear and tear. The whining continues whenever it is being driven. Whatever happened to companies being responsible for the quality of the vehicle! god knows most of us cant buy a new one at $35,000+ to.
