Electrical system
Problem: Gm is recalling certain model year 2006-2009 buick, lucerne; cadillac dts; hummer h2; model year 2008-2009 buick enclave; cadillac cts; model year 2007-2009 cadillac escalade, escalade esv, escalade ext; chevrolet avalanche, silverado, suburban, tahoe; gmc acadia, sierra, yukon, yukon xl; saturn outlook; and model year 2009 chevrolet traverse vehicles equipped with a heated washer fluid system (hwfs). A recall was implemented in 2008 to add a fuse to the control circuit harness to address the potential consequences of a printed circuit board (pcb) electrical short. However, there have been new reports of thermal incidents on hwfs modules after this improvement was installed. These incidents resulted from a new failure mode attributed to the device's thermal protection feature. The significance varies from minor distortion to considerable melting of the plastic around the hwfs fluid chamber.
Risk: It is possible for the heated washer module to ignite and a fire may occur.
Fix: Dealers will permanently disable and remove the heated washer fluid module. An updated page for the owner manual will be provided and inserted in the owner manual to document that the feature has been permanently disabled and removed from the vehicle. The safety recall began on june 11, 2010. Owners may contact buick at 1-866-608-8080, cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438, saturn at 1-800-972-8876, gmc at 1-866-996-9463 and hummer at 1-800-732-5493 or at the owner center at www.gmownercenter.com.
Electrical system
Problem: Gm is recalling 857,735 my 2006-2008 buick lucerne; cadillac dts; hummer h2; my 2007-2008 cadillac escalade, escalade esv, escalade ext; chevrolet avalanche, silverado, suburban, tahoe; gmc acadia, sierra, yukon, yukon xl, saturn outlook; and my 2008 buick enclave vehicles equipped with a heated wiper washer fluid system. A short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire.
Risk: This may cause other electrical features to malfunction, create an odor, or cause smoke increasing the risk of a fire.
Fix: Dealers will install a wire harness with an in-line fuse free of charge. The recall began on september 12, 2008. Owners may contact buick at 1-866-608-8080; cadillac at 1-800-982-2339 or http://www.cadillac.com; chevrolet at 1-800-630-2438; saturn at 1-800-972-8876 or http://www.saturn.com, gmc at 1-866-996-9436; or hummer at 1-800-732-5493; or through their website at <a href=http://www.gmownercenter.com>http://www.gmownercenter.com</a> .
Equipment:other:labels
Problem: Certain trucks and sport utility vehicles fail to conform to the requirements of federal motor vehicle safety standard no. 110, "tire selection and rims." these vehicles were shipped with tire and loading information labels listing an inacccurate vehicle capacity weight.
Risk: A misprinted label could lead to improper vehicle loading specifications or tire inflation which could result in a tire failure, increasing the risk of a crash.
Fix: Owners will be provided with corrected labels and installation instructions. At the customer's option, a dealer can install the label for them. The recall began on march 31, 2006. Owners may contact buick at 1-866-608-8080, cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438, gmc at 1-866-996-9463, hummer at 1-800-732-5493, pontiac at 1-800-620-7668, saturn at 1-800-972-8876, or isuzu at 1-800-255-6727.
Steering:hydraulic power assist:hose, piping, and connections
Problem: Certain passenger vehicles may have been built with a power steering hose that is not to specification. Under extreme steering maneuvers, such as turning the steering wheel fully to the left or right while braking, the hose may fracture and leak fluid.
Risk: If this were to occur, power steering assist would be lost and increased steering effort would be required. On vehicles equipped with hydro-boost power brakes, it could also result in loss of power brake assist and increased braking effort would be required. If the power steering fluid spray were to spray onto hot engine parts, an engine compartment fire could occur.
Fix: Dealers will inspect the power steering hose(s) for two suspect date codes and replace them if required. The recall will begin on october 14, 2005. Owners may contact chevrolet at 1-800-630-2438, gmc at 1-866-996-9463, buick at 1-866-608-8080, cadillac at 1-866-982-2339, isuzu at 1-800-255-6727, or hummer at 1-800-732-5493.
