NHTSA lists 8 safety recalls covering the 2003 Chevrolet TrailBlazer. Open recalls don't stop you from selling or junking the car, but check your VIN at nhtsa.gov/recalls to see which apply to yours.
On certain trucks and sport utility vehicles, the driver wishing to signal a turn by moving the directional signal lever, (up or down) may cause the front marker/turn lights and rear turn lights to flash in a manner similar to hazard warning, rather than flashing on the desired side only.
Risk: The driver may not be able to clearly signal their intentions to turn, change travel lanes, or potentially warn others of an impaired vehicle operating condition increasing the risk of a crash.
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.
Risk: 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
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…
Risk: Depending on the occurrence and weather situation, driver visibility could be reduced, which could result in a crash.
Certain minivans, passenger and sport utility vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 225, "child restraint anchorage system." the owner's manual does not explain the meaning of the location symbols for the child restraint lower universal anchorage system.
Risk: This does not meet the requirements of the standard.
Certain sport utility vehicles were built with a left-front brake pipe with a circumferential score at a random location along the length of the pipe as the result of the manufacturing process. If the brake pipe partially or fully fractured, brake pedal travel would immediately increase and front brake performance would be reduced.
Risk: If braking performance is reduced, a crash could occur.
Certain sport utility vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 114, "theft protection." these vehicles are equipped with a mechanical override that could allow the ignition key to be removed with the shift lever in a position other than park. In addition, these vehicles have an…
Risk: These overrides are not permitted unless the vehicle has a locking steering column.
On certain mini vans, passenger and sport utility vehicles, some of these vehicles have a driver's side air bag that may not deploy as designed. In addition, the air bag inflator could rupture.
Risk: This could result in reduced capability of the air bag to protect the driver. Also if the air bag inflator ruptured, pieces of the inflator could strike and injure the vehicle occupants.
Certain passenger, mini vans, and sport utility vehicles have an air bag inflator on the driver's side that could fracture at a weld during a deployment.
Risk: Pieces of the inflator could strike and injure vehicle occupants and the air bag cushion would not inflate fully, reducing the capability of the bag to protect the driver.
