2008 Hummer H2 Problems
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.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
The steering wheel position sensor may fail, resulting in the service stability message being displayed.

2008 Hummer H2 Recalls
The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.
The wiring to the washer system heater may overheat due to a failure in the heater module. This could cause other electrical features to malfunction, smoke to develop, and an electrical fire could result. Dealers will install a wire harness with an inline fuse to protect the washer heater module. This recall is expected to begin on September 12, 2008. The General Motors recall number is 08048.
On some trucks, wiring for the ABS wheel speed sensors may be reversed, which could cause increased stopping distance. This condition could increase the risk of a crash. Dealers will correct the ABS wheel speed sensor wiring and reprogram the brake control module if necessary.

Purchased in Jan.2010 to be used as everyday driver and 25' boat hauler. Have not regretted trading in a perfectly good 2007 Acura MDX for it. I have added the nominal performance upgrades (exhaust, intake, chip) which certainly boosted power but no increase over stock mpg. 13mpg at best on highway.
