Recalls
3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Visibility (wipers, glass) Vehicle recall #04V046000 · 2004 · 581,394 vehicles
What's wrong: Certain sport utility vehicles have windshield wiper systems that will not turn on, cease operation while in use, fail to turn off/on by themselves (moisture sensitive wiper system), or have continuous windshield washer pump operation because the presence of water within the wiper modules can either cause a short circuit or can lead to the corrosion of components within the module.
Why it matters: Depending on the occurrence and weather situation, driver visibility could be reduced, which could result in a crash.
The fix: Dealers will cover the windshield wiper module vent hole with a patch. Also, the wiper motor, circuit board, and electrical connector will be inspected to signs of water intrusion and/or corrosion and be replaced as required. The recall began July 6, 2004. Owners should contact Chevrolet at…
Exterior lights Vehicle recall #04V527000 · 2004 · 871,473 vehicles
What's wrong: On certain sport utility vehicles, vibration and heat May cause the tail lamp/stop lamp bulb to loosen in its socket. If this occurs, the bulb May flicker and eventually become inoperative.
Why it matters: An inoperative brake lamp will not convey the driver's intention of stopping to drivers in following vehicles, and an inoperative rear turn signal lamp will not convey the driver's intention to turn to drivers in following vehicles. Both of these failures can increase the risk of a crash.
The fix: Dealers will inspect the tail lamp/stop lamp assemblies, and if necessary, replace them. The recall began on November 22, 2004. Owners should contact Chevrolet at 1-800-630-2438, Oldsmobile at 1-800-630-6537, Buick at 1-866-608-8080, or GMC at 1-866-996-9463.
Latches & locks Vehicle recall #05V494000 · 2005 · 98,007 vehicles
What's wrong: Certain sport utility vehicles have a rear side closure latch that May not latch or unlatch due to corrosion caused by road splash, such as water and road salt. These vehicles were originally sold in or currently registered in the following states: connecticut, delaware, illinois, indiana, iowa, maine, maryland, massachusetts, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania,…
Why it matters: If the door is not latched properly and it goes unnoticed, it May open while the vehicle is in motion. If an unbelted occupant fell out of the vehicle, personal injuries could occur.
The fix: Dealers will install a seal along the lower part of the rocker panel to prevent intrusion of corrosive material, and inspect the rear side closure latches. Functional latches will be cleaned and lubricated. Non-functioning latches will be replaced. The recall began on February 24, 2006.
