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.

2003 GMC Envoy Owner Comments

problem #4

Mar 072008

Envoy 4WD 6-cyl

  • Automatic transmission
  • 59,000 miles


The contact owns a 2003 GMC Envoy. The contact smelled gasoline, but did not pay it any attention initially. His son entered the vehicle later and also smelled the strong odor. The following day the contact filled up the tank with gasoline and the smell intensified. When he arrived home, he noticed a fuel leak by the rear driver side wheel. A mechanic stated that the leak originated from the top of the fuel tank where the fuel pump connects. The contact dropped the vehicle off at the dealer the next day and they stated that the leak originated from the gas tank, and it needed to be completely replaced. The vehicle is still at the dealer. The current and failure mileages were 59,000. Updated 04/16/08. The transmission was slipping and would not engage in 1st gear. The air condtion was blowing hot air. The ignition swithc shorted out.

2 complaints noticed enginee running hot, added fluid to radiator, near empty. A couple of months later, same thing. 3 months later, during oil change, mechanic indicated while doing checks that the radiator fluid was low. Told him this was the third time, he added fluid, pressure checked radiator - no holes or leaks. Seems to be evaporating. Air conditioner blowing hot air (excluding the fact the panel with ac controls quick working a loooonng time ago). Took in to dealer for repair. After $600 and all day visit with dealer, the piece broken was the size of a 2"-4" block of plastic. This little piece just quick working, it was referred as a control switch of some sort under the dash board. Sounded kinda hokey to me - I can imagine a compressor going out and you do not have cold air - the name of it escapes me - but the mechanic did indicate there was some sort of technical report out there on it as well. Just found out from husband the name of the piece - the actuator door quit.

Air conditioning runs hot- there is a technical service bulletin out for this but it needs to be an open recall to be fixed--- needs reflash for control head-that's what my mechanic said.

Wind noise coming through driver and passenger windows. Molding was replaced and noise wasn't reduced. Dealer stated, GM knows about the problem and seem to believe that the mirrors are causing wind to be redirected to the window. Therefore wind is coming through where the glass goes inside the door. not satisfied with this car, can't even drive with the radio turned down. Also the low-pressure sensor in the air conditioner unit was replaced, after a half-pound of freon was required. This vehicle has been in the shop four times!!!
