Steering Vehicle recall #05V455000 · 2005 · 123,592 vehicles
What's wrong: 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.
Why it matters: 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…
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.

What's wrong: 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.
Why it matters: 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.

The short May also cause overheating, which could melt components of the door module, producing odor, smoke, or a fire.
Why it matters: 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: Owners will be contacted and dealers will test the driver's door module. If the module is functioning properly, a protective coating will be applied.

Why it matters: 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.

Exterior lights Vehicle recall #15V519000 · 2015 · 429,170 vehicles
What's wrong: In the affected vehicles, the headlamp driver module (hdm) May overheat and fail, causing the headlamps and daytime running lights to not illuminate.
Why it matters: 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.
Visibility (wipers, glass) Vehicle recall #15V599000 · 2015 · 9,932 vehicles
What's wrong: 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.
Why it matters: 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.
