The wipers were the first to go. That needed a control module. The touch pads for the tail gate were next. First the drop down then the swing. Then the right side passenger door inside handle stopped working. Then the left side rear door outside handle doesn't work. Then the four wheel drive doesn't work. Then the fuel gauge doesn't work. Now the passenger's window doesn't open. 5th speed on the heater stopped working. What is the matter with GMC? that is a high end vehicle and as such should not be plagued with such problems.

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.

Consumer states that 2005 GMC Envoy sle doesn't have a rear door ajar warning. Consumer would have to get a model with that on it, it doesn't come standard.
