Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

2006 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.

At customers' request, a dealer can install the label for them. The recall began March 31, 2006. The GM recall number is 05109.
