NHTSA investigations into the 2007 Hummer H2

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Recalls on the 2007 Hummer H2

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2010189 99,000 units in Canada

Accessories

On certain vehicles equipped with a Heated Washer Fluid System (HWFS), a short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. A repair was implemented in a recall in 2008, however, there have been new reports of thermal incidents on heated washer fluid system modules after this improvement was installed. This situation may cause some minor distortion, but also could lead to melting of the plastic around the heated washer fluid system, or cause a fire. Correction: Dealers will permanently disable and remove the heated washer fluid module. An updated page will be provided and inserted in the Owner Manual to document the removal of the feature.

Recall 2008313 54,431 units in Canada

Other

On certain vehicles equipped with a heated washer fluid system, a short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. This situation may cause other electrical features to malfunction which could cause smoke and in some cases a fire. Correction: Dealer will install a wire harness with an in-line fuse.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.
