After my H2 is parked awhile (mostly overnight), I will find the rear end has "dropped" approximately 6" as compared to the height of the front end. The rear end will regain its height once the engine is turned on. This happens intermittently.

2005 Hummer H2 RecallsRear Seat Belt for Smaller Passengers May Not Fit Correctly
The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005. The GM recall number is 05037.
On vehicles equipped with the Bosch hydraulic brake booster, the boost pressure accumulator may crack and break away from the hydro-boost assembly during normal operation. If this were to happen while the hood is open, fragments from the accumulator could injure people standing in the immediate area. The loss of fluid while driving would cause increased steering and braking effort and a crash could occur without warning. Dealers will test the hydro-boost assembly for function of the two-function valve. If the hydro-boost assembly fails the test, it will be replaced free of charge. The recall began March 23, 2005. The GM recall number is 05006.
