    Looks like I will have to having mine replaced because the back is sagging badly. Does anyone know how much this cost?

    FOR FEW MONTHS, BACK OF MY CAR LOWERED BUT IT CAME BACK UP SLOWLY WHEN I START ENGINE/ BUT RECENTLY FOR 3 DAYS IT STAYS LOW AND VERY BOUNCY WHILE I'M DRIVING.

    Just another major problem that needs to be fixed. Did GM plan for all their systems to fail or should this whole model be recalled as a lemon!

    Every 2 or 3 days my car will have sagged overnight, sometimes it will raise once I start the ignition and other times it will stay sagging for the entire day. It is very irritating because the truck will drive so raggedy.

    Went to leave work one day and the tailend of my car was almost sitting on the ground. When I crank the car up you can actually hear the air compressor come on and it pumps the car right back up. It didn't happen again for several weeks but now it is starting to happen more often but still very random.

    Rear end of SUV keeps dropping and upon a restart will lift up, only to fall while driving.

    Air Ride & Electrical Issues! My wife loves this vehicle and it was trouble free until recently. As other posts state, the rear of the Rainier will sit down if not driven for a couple days. I suspect a slow leak in a line or fitting and a liberal application of 'Snoop' may identify it... have yet to find the gumption to get under the vehicle. Also, the electical issues have started. First the A/C controls malfunctioned and where replaced, and now the guage cluster is giving erroneous readings - or none at all. The speed reads low or 0, the oil pressure pegs high, and the gas level is questionable. So far the digital 'miles to empty' idication has remained functional. If anyone knows of a recall or a way to get GM to recognize this as their problem, please let me know.

    My air ride compressor went out, wish they made a way you could manually air up til repair.

    Haven't fixed it yet. In fact I only recently became aware that the air compressor was not coming on when I started the car. (The compressor does activate when I turn it on to use it as a tire inflater.)

    Feels like I'm riding a roller coaster, and I can't drive up anything too steep because bottom scrapes. Seemed like it went down and then never came back up
