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.

2002 GMC Sonoma Owner Comments

problem #5

Mar 202012

Sonoma 6-cyl

  • 64,988 miles


While braking for a yield intersection on 3/30/2012, approx. 10am, in dry and clear conditions, brakes on 2002 GMC Sonoma failed. Vehicle would not stop despite hard pressure on the brake pedal and ran through intersection almost colliding with another vehicle. When managed to get vehicle stopped and pulled to side of road, both the ABS and brake failure warning lights were illuminated on the dash. Upon turning the ignition off and restarting, both the ABS and brake failure warning lights cleared and were no longer illuminated. Check engine light never illuminated. Took vehicle to both independent mechanic and GM dealership mechanic and both confirmed an odb II trouble code of C0265 had been generated. This code, I was told, indicates failure of the ebcm (electronic brake control module) of the ABS system. Apparently, this problem is well-known to GM and it has issued several technical service bulletins on the problem, but no recalls. Independent mechanic could not replace the ebcm as lacked the proprietary GM software needed to program it. GM dealership mechanic--while confirming generation of the C0265 trouble code--refused to replace the ebcm instead saying I should "just drive it around and see if the problem happens again." This seemed a very dismissive approach by GM to a known problem on certain of their ABS vehicles as the first brake failure on 3/20/2012 almost caused a wreck. Not anxious to find out what the second failure the GM dealer wants me to "wait for" would result in.

Sonoma 6-cyl

While driving. The consumer heard a squeaking sound. The consumer found that the vehicle needed brakes at 29000 miles on the driver's side. The consumer took the vehicle in for an inspection and found that the vehicle needed new brakes on both sides. However, the dealer did not want to put factory brakes on the vehicle they want to use a product call dura stop.
