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.

2008 GMC Envoy Owner Comments

problem #2

Jul 202010


  • 31,300 miles


While on our way back to our motor home the brake pedal on my 2008 GMC Envoy went to the floor when I tried to stop in heavy traffic on hwy 503 in the state of Washington. After pumping the brake quickly I was able to regain some braking power. When I called the local GMC dealer (carr GMC) in vancouver the service adviser confirmed that it was the master cylinder. Now this happened on Tuesday July 20, 2010, the service adviser gave me an appointment for Thursday July 22 between 9:00 to 9:30 am. I arrived at 9:10 am and was told that it would take 2-1/2 to 3 hours to diagnose the problem. Now this was the same person that told me on the phone two day prior that I had a bad master cylinder. Now I just drove this car 48 miles with the brakes not working properly. The dealer did not have a master cylinder in stock and was having one overnighted in from lancing, mi and would call me when it was repaired. Now I don't know of how many other vehicles this has happened too, but having a master cylinder fail on a car that has only 31,000 miles on it is not good and a real safety issue.

The brakes on our GMC Envoy "skip" when there is wet weather, bumpy roads and especially snow. When trying to brake, the brakes don't seem to grab and it takes extra long to stop. We haven't had any crashes, but several close calls due to the brakes not engaging. In dry and normal weather, they work fine.
