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.

2002 GMC Envoy Owner Comments

problem #1

Jan 022008

Envoy 4WD 6-cyl

  • Automatic transmission
  • 106,000 miles

A D V E R T I S E M E N T S

I was driving along interstate 75 at night with my 3 year old, 16 year old, and 18 year old nephew returning to college after winter break on Jan. 2,003. We were left stranded on the side of the highway, after we almost wrecked. The gears were jumping back and forth from 2 wheel to wheel drive. I took to a local GM dealer and they told me that it would costs me 2500 to repair-the problem the front differential. I contacted the 1800 GM service line and they said that they would not be assisting with repairs due to mileage. I asked around at different auto repair and transmission shops and they said that GM knows they have a problem with the differential in Envoy, trailblazers, and Isuzu. Even if the problem gets fixed, im told there is no guarantee that the problem will not happen again until GM addresses the actual problem with the differentials. I believe my gear problem caused the differential to fail. Meanwhile I am stuck with a car that I have to pay for another year and a half on. It is really an inconvenience to me. I cannot afford the repair, the car sits in the driveway. Im behind on my car payment, having to rent a car to drive to work. GM should be held accountable. Other problems include the clutch fan going out, costing me over $500 to repair on my own. GM refused to help. This went out at 33,000, shortly after purchase. I am really burdened right now and don't know what to do.
