general problems of the 2005 GMC Envoy

The contact owns a 2005 GMC Envoy. The contact stated that the automatic door locks failed to lock and unlock the vehicle. In addition, the rear hatch door failed to unlock when initiated. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 88,000.

In June of 2007 I could not close either of the rear doors on my vehicle. They failed approximately two hours apart. I was transporting two grand children at the time. Thank heaven they were young enough to require car seats. We were at the mercy of strangers on the highway. With donated rope to secure the doors we made it home. The dealer replaced both door lock assemblies. I paid $125 for labor only. The dealer must have replaced the door lock assemblies with the same faulty part. On 10/12/10 the left rear door failed again! after tying the door and using duct tape to secure it I drove the 30 miles to the nearest dealer. Although I had to pay $295. 35 to replace the left rear door lock assembly the dealer was able to do it immediately. I am now carrying rope and duct tape in anticipation of failure of the right rear door lock. My vehicle is well taken care of. Maintenance is followed religiously. (there is nothing in the manual to indicate door locks should be checked. Lubricated but not checked for possible failure. ) these failures are in no way my responsibility. This is a faulty design that can very well end in injury. I would have assumed that gm would have been concerned and if not issue a recall take responsibility for the defective locks. Have dealer service departments check these locks when vehicles are brought in for normal maintenance. Not only do they not take responsibility they actually replace the locks with the same lock assembly that is doomed for failure.

Vehicle: 2005 GMC Envoy xuv issue: rear door latches failed due to excessive rust build up. Problem is exactly like that found on 2002-03 Envoy. Road salt gets into latch and rusts out. Both door effected and required rem=placement.

Purchased the 2005 GMC Envoy xuv used in 2009 with 41000 miles. Within 3 months the Envoy started having rear door latch failures. The rear door and glass can be opened in a traditional side door mode or a truck bed mode. Frequently the electronic latches that operate to let the door function in either way would fail. The Envoy has been in several times over three years to have all the latches repaired and or replaced. Each latch has been replaced several times. When the latches fail, and they have failed in a configuration that when I tried to open the door in a side door way, three latches let lose and the door fell open with only one latch holing the rear door on. I was forced to have to lift the door back into the slots where the door pegs lock into the latches. One time three latches failed and I had to use bungee cords to keep the door closed so that I could drive it to the dealer to have the latches replaced. The dealer charges me 50 dollars per visit per the warranty, however the vehicle has to go in at least 3 times a year to have the latched looked at and repaired or replaced. They replace the fixed latches at no cost but I still get charged 50 dollars for the visit. The warranty is soon to be off this vehicle. Also the gas guage failed to operate correctly within months of owning the Envoy. The gas gauge would show more fuel then what I had, or show no fuel whatsoever even though I had just filled the gas tank up. The gauge needle would bounce back and forth all the time or get stuck full or empty as well. It was found that there was a bad fuel level sensor in the tank. It was replaced. I have also had to replace the front pinions of the Envoy twice during the three years I have owned it because they were leaking. I have also had to have the differential carrier overhauled because the front differentials were both leaking. These pinions and differential repairs were three different visits to the dealer, not at once.

1. Events leading up to the failure were normal driving in winter conditions. 2. Passenger door latches seize from corrosion. Passenger doors will not open, passengers could not exit vehicle after a 4 hour ride. There is no seal to prevent water, salt, debris from entering the inside of the door and the door latch mechanisms during normal vehicular operation. 3. Door latches were replaced.

Prob #1 driving down street rear door came open and wouldn't close. Already replaced the door latch on pass rear door. If I had children in the car this would've been extremely dangerous. Talking to others this is not an isolated incident. Problem #2 fuel gauge just stop working, low fuel light beeps constantly. Never know how much fuel is in car. Cost to replace over $500!.

Rear glass door came unglued at hinges damaging the struts and almost falling on my head. Dealer was contacted and replacing the glass door was suggested at $1500. 00. Repairing attempted using glue and glass door came loose again. It was a near miss, could become a fatality. Main rear door struts were damage and the door almost hit me again.

Car switches into all 4w and higher by itself. I had been to a dealership 3 times in one year for which they were unable to find the problem. Now my warranty is up. After that I took it to a transmission shop where they supposedly fixed the problem for over 800. $ a week later it did it again. Now I have the 4wd disconnected for safety reasons. I would be driving on the freeway at 60-75 mph and if would switch and not come out no matter what I do. I have owned this vehicle for almost 5 years and it has done this the whole time. I am a single mom and I drive my 17 and 7 year old around in this car. Even with it disconnected it still tries to switch. There is no specific time, temperature, or other reason this happens. It has happened when I turn on the car and sometimes I can go a couple of weeks and other times it happens daily. I also have had my lights not go on for no reason and also the doors lock and can only be unlocked by using the key. And the hatchback will not open at all when this happens. Electrical?? help!!.
