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.

2004 GMC Envoy Owner Comments

Envoy 6-cyl

  • Automatic transmission
  • 23,000 miles


GMC Envoy SUV (4.2) inline 6-cylinder. Vehicle has stalled five times intermittently over the past six months. It stalls out when you begin to stop or start to accelerate from a stop or just while idling. Luckily it hasn't been when I was trying to pass or merge in traffic. The first time was around 23,000 and the second time 23,500. The next occurrence happened while it was sitting in a parking lot idling and it died after running for 5-8 minutes. I took it to the dealer and they said it was the throttle body that needed cleaning - done. Six weeks later and 1500 miles it stalled when I was trying to make a U-turn in St. Petersburg and I nearly got rear ended. Dealer kept it two days and did nothing since they couldn't duplicate problem and couldn't get anything from the computer. I took it back to the dealer on 7/21 for regular maintenance (oil change, fuel filter change, and A/C repair-bad clutch). The dealer said they had two computer module updates, one to fix stalls. Three days later it stalled in jacksonville traffic at a stop light. I have taken it back for a fourth time to the dealer and left for a week. Dealer said vehicle idling rough but computer not registering problem so nothing was done, again. I E-mailed GM and I have had no reply in two weeks. I see where a person with a V8 version is having the same problem. This is an accident waiting to happen.

Envoy 4WD 6-cyl

  • Automatic transmission
  • 4,000 miles
I bought my GMC Envoy in January 2004 for approx. $42,000. This car has everything. After about 2 months of the purchase, my gps went out and had been fixed twice. My brakes do not always work --sometimes they slip especially when I need them most -which is scary. GMC said that they have heard about this problem before, but did nothing to resolve the problem. The engine stalls periodically. GMC said they do not know why. The gas gauge and odometer do not work properly. When I brought my vehicle into North county GMC dealership in san diego for repairs I mentioned my gas gauge did not work along with many of the other issues. After they repaired the odometer by replacing the cluster, the gas gauge still did not work. Every single time these problems happen I am forced to pay a $100 service charge just so they can look at it and because I am in sales, I am also forced to get a rental car. After all this, I am still quite displeased with GMC. I hate to say it but they are supposed to be the best american car "?professional grade?" and if this is true I will never buy an american vehicle again. GMC said they would be checking on all these problems and every single time I picked my Envoy up after they supposedly fixed the problems, I found several issues still unresolved. They suggest I need to set another meeting to bring my Envoy in and of course will cost another $100.
