Dear sir/madam, I have a 2003 gmc envoy slt model 4.2l v6 4wd and as I was backing into my garage I heard a loud bang and whinning noise and I now have no reverse gear and when I select the drive gear on the automatic transmission I have a whinning noise, I have read the blogs on this issue and I believe that gm and gmc are very aware of this problem, this repair will cost me up to $2,800.00 plus tax to have the transmission removed and a re-manufactured on replaced on my vehicle. I was just glad that this matter happened at my residence and not on some back road in west va., I believe that as stated, gm and gmc is very aware of the problem with the 4l603 transmission that were used in these vehicles' and the problem with the sun-shell and the reaction sun gears that are like a grenade exploding inside the transmission. I would like for a recall to be started on this problem and the owners to be paid back on all of these repairs. The consumer stated the air ride suspension that was installed on the vehicle is dangerous. The air ride suspension deflated on both sides on the rear of the vehicle, which caused the vehicle to bottom out on stops. Updated 07/08/15

Was inspecting car and had several complaints to dealership that front end had a strange noise when we go over a rough road. While trying to figure out where fuel smell is coming from I noticed a crack on the weld next to the shock mount . I also noticed that there has been a previous repair there because we have had this car since it was new all I can think is that they saw this and did a repair and not telling us so if your car is creaking check the front end could be falling apart.

When the weather got below freezing, the air bag suspension would not air up. Now, every time I turn off my car, the suspension goes down and it will not air back up until I turn the car back on. If I have passengers in the back seat the suspension will not work. Several times the suspension has deflated while I was driving and if I'm going at highway speeds, the vehicle begins to shake and wobble back and forth. It is very scary and I don't even like having my kids in the car because it seems so dangerous. I have read countless complaints on the internet about other envoy owners having the same problem. This should be on gm's recall list.

Gmc is suppose to be quality however, the rear suspension starts out getting lower and lower until the rear suspension dropped to the point that the vehicle was unsafe to be driven. Because the truck was sitting on the rear tires and if the vehicle were to be driven, the tires would blow out and cause a crash and possibly a fatality! There are several complaint and concerns about the same issue yet nothing is being done.

The car dies for no reason it has been doing this since the first day I got the car. The car also functions like it has hydrolics for a while it will be low to the ground while I'm driving it then out of no where it would raise up I had to get the suspension done when I got it because it was old and also the key gets stuck in the ignition also if I press the unlock button it will turn on the heat this car has been a headache.
