2006 Chevrolet Trailblazer EXT recalls

Visibility: power window devices and controls

NHTSA campaign 15V599000 · reported September 24, 2015 · General Motors LLC · 9,932 vehicles potentially affected

The problem
General Motors LLC (GM) is recalling certain model year 2006-2007 Buick Rainier, Chevrolet Trailblazer and GMC Envoy vehicles, and 2006 GMC Envoy XL and Chevrolet Trailblazer EXT vehicles. Fluid may enter into the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board, causing window switches to become inoperative. Previously, the affected vehicles may have had their master power window switch module treated with a protective coating, instead of having it replaced.
The risk
The protective coating may not eliminate the risk that the circuit board could short and result in a fire, even while the vehicle is unattended.
The fix
GM will notify owners, and dealers will install a new driver's door switch module, free of charge. The recall began on November 2, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is 15700.

Exterior lighting: headlights

NHTSA campaign 15V519000 · reported August 14, 2015 · General Motors LLC · 429,170 vehicles potentially affected

The problem
General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
The risk
Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.
The fix
GM will notify owners, and dealers will replace the HDM, free of charge. The recall began on May 17, 2016. Owners may contact Buick customer service at 1-800-521-7300 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14291.

Visibility: power window devices and controls

NHTSA campaign 14V404000 · reported July 2, 2014 · General Motors LLC · 184,611 vehicles potentially affected

The problem
General Motors LLC (GM) is recalling certain model year 2005-2007 SAAB 9-7x; 2006 Chevrolet Trailblazer EXT and GMC Envoy XL; and 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier and Isuzu Ascender vehicles. Fluid may enter the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.
The risk
A short in the circuit board could lead to a fire, increasing the risk of personal injury. A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made.
The fix
GM will notify owners, and dealers will inspect the part number on the door module, and install a new door module if necessary, free of charge. Parts for the remedy are not currently available. An interim letter was mailed to owners in August 2014. A second owner letter will be mailed when parts are available. Owners may contact GM customer service at 1-800-521-7300 (Buick), 1-800-222-1020 (Chevrolet), 1-800-462-8782 (GMC), 1-800-955-9007 (SAAB), and 1-800-255-6727 (Isuzu). GM's number for this recall is 14309. NOTE: This recall provides a new remedy for all vehicles covered by recall 13V-248. Vehicles whose modules were modified but not replaced as part of the previous recall remedy must have their vehicles remedied again under this campaign.

Equipment: other, labels

NHTSA campaign 05V552000 · reported December 7, 2005 · GENERAL MOTORS CORP. · 32,068 vehicles potentially affected

The 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.
The 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.
The 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

NHTSA campaign 05V455000 · reported October 5, 2005 · GENERAL MOTORS CORP. · 123,592 vehicles potentially affected

The 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.
The 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.
The 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.
