Mechanical Jack Problems of GMC Envoy

The contact owns a 2003 GMC Envoy XLT. The contact stated the jack that holds the vehicle up while changing a flat was locked in place which made it impossible to release and lower the vehicle to the ground. The mechanical jack had to be kicked from underneath the vehicle in order to release it. There was also a crack in the rear drivers side rim. The dealer was not contacted. The failure mileage was 73,000.

I had a flat tire and went to use the GMC provided jack and spare tire. The jack was held in by a large rubber band that broke as soon as I started to remove it. When I went to lower the spare tire down I heard a "crunch" come from the gear end of the spare tire pulley. The spare tire pulley, which was made of plastic, broke into pieces and wouldn't allow the tire to be lowered anymore or raised. GMC should be ashamed of themselves for providing such a lousy system on something that is obviously used in an emergency situation. Nice way to save a few dollars.

The contact stated the jack that the vehicle is equipped with is inadequate. The jack has two extension handles, but the extension handles are not long enough to be turned without getting under the vehicle. Had a flat tire, and when the contact put the jack together she realized the jack handles were not long enough. Her father had to crawl underneath the vehicle to use the handle. Called the manufacturer about the jack handles ,and they stated the jack should be efficient, and if a person had to get under the vehicle, he would not be held responsible.

The jack on the 2002 GMC Envoy 4x4 is not adequate for the vehicle. It has to be placed in a very limited number of locations under the vehicle, and will not work at all unless the pavement is absolutely flat (no cracks in the cement!). My vehicle was sold new with skid plates for off-roading, but the jack is totally unusable on a dirt surface and it sometimes even on pavement won't jack the vehicle high enough to get the tire off the ground.

The bumper jack is unsafe. When jacked to its full height under a load, the jack's cork screw moves, misalign itself, from the jack's body. Therefore, you are unable to screw it back into its body due to the misalignment. In order to remove the jack, I had to drive off of it.

The consumer was trying to change a flat tire in the rear of the vehicle and noticed that jack handle is too short, causing the consumers body to be almost under the vehicle.
