Average Mileage: 126,139 mi (13,000 mi - 212,000 mi)
The rear end drops on the tires and if you start the car it will rise but then by the end of the day it drops (like a low rider cars)

I have the same problem. The rear goes down from time to time. When riding down the road I can feel the back getting low. When it does, the ride is very bouncy and very uncomfortable. When I stop and turn off the engine for a few minutes the back rises up again and the ride is smooth sailing. The air compressor for the rear may go out for a few days or I may not have that problem again for a few days or even weeks. Its very frustrating!!!!

deflates when sitting and engine turned off. Inflates within about 20 seconds of starting engine.

Yes I have also had this problem. I have replace the rear passanger punp and now am having problems with the rear driver side.
I bought my 2002 Bravada from an auction here in Indy sometime in September 2014, and it was fine when I test drove it. It started right up and I didn't even notice it was a rear air ride suspension because it didn't have to take any time to air up or give me any problems on the test drive. I guess I would have to say my problems didn't start until around November 2014 (just about 2 months after I got it) when I had to load it up with all my daughter's things to move her back home from a neighboring state. We had a lot of clothes and things to move back but I don't believe it should have been enough to do any type of damage to my vehicle. But anyways, we had to stop not even a mile down the road from where I picked her up because I noticed we were starting to bounce around.

at times it sits low. I haven't figured out when it raises and when it lowers.
