    My husband is at the GMC dealer right now having our 2003 Envoy SLY rear suspension repaired. We took it in on Tuesday they did a diagnostic and tole us the compressor was burned out. Replacement $600+ and labor costs $95.00 per hour. While my husband was at home for them to call him to pick up the vehicle they then said and I quote" we put the new compressor in and parked the truck outside for a few hours and the rear fell down again." Apparently, they put it back on the lift and now say that the rear airbags have a leak and a new pair cost $465.00 plus labor. We are not letting them touch the car. We are going to bounced to the junkyards at Hunt's Point in the Bronx and buys some parts there. *I'll take my chances with my Dominican repair guy because he has never ripped me off or failed to repair my vehicle with a money back guarentee. Why didn't GM recall this truck??? This is ridiculous for this many people to be having this same expensive problem and we can get no recall? We need to get together and contact General Motors.

    rear suspension goes down after sitting for a few hours and goes up after I start the vehicle. What has to be replaced..the air bags? how much is it going to cost

    The rear air suspension fails to fill up when the temp drops below freezing. You can hear the compressor running, but it does not fill up. It has been looked at several times by different mechanics and no fixes seem to satisfy the problem. Only taking it inside for a few hours and allowing it to warm up seems to make it better. Which is fine for those with a garage, but not all of us have one

    Rear air suspension fails in cold temperature. Took vehicle to certified dealership and recieved no answers. I am completely stumped as to why the cold would effect the air ride. It works perfect until it gets down around freezing and then will not air up on the rear. I love this car and do not want to trade so if anyone has found a solution I would be forever greatful.

    The air suspension fails because it's a terrible design. The primary cause of failure is the small air pressure fittings on top of the bags, it will happen on new ones too if the little hose does not seat perfectly. The seating of the hose changes when you hit large bumps. The secondary cause in the control valves in the pump, they are also poorly designed. My fix was to machine out the bags and put commercial compression fittings with commercial small diameter airlines on. Have never seen the problem again since. The fittings on top of the bags are activated with air pressure, when activated they squeeze the cheep air tube to complete a seal. This design leaks regularly right out of the fitting thus so many people have the problem. In this case the ultimate fix is not going OE, it's going aftermarket or modification.

    Air bags in the rear would not air up anymore - pump is fine, replaced the air bags with coil springs

    The Envoy will drop when parked. Suspension gives out. The Suspension will activate again once I start up and stay good for duration of drive.
