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.
Water may enter the windshield wiper motor module resulting in damage over time. The wipers may work intermittently or not at all. Visibility could be reduced, increasing the risk of a crash. Dealers will inspect the wiper module cover and replace it if necessary to correct this concern. The General Motors recall number is 08243.
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.

This leads me to believe that the design itself is flawed. Especiall...
