On certain pickup trucks and sport utility vehicles, the galvanized steel tailgate support cables that retain the tailgate in the full open (horizontal) position may corrode, weaken, and eventually fracture. If both cables fractured, the tailgate would suddenly drop and strike the top surface of the rear bumper. Anyone sitting or standing on the horizontal surface of the tailgate when both cables fractured could be injured by falling from the tailgate. On vehicles that have had the bumper removed, the tailgate may drop even lower. Additionally, if there is cargo on the tailgate the cargo may fall off if the support cables fracture.
Dealers will replace the cables. The manufacturer has reported that owner notification is expected to begin during the third quarter of 2004. Owners may contact Chevrolet at 1-800-630-2438; Cadillac at 1-866-982-2339; or GMC at 1-866-996-9463.
Report Receipt Date:
Certain sport utility vehicles, pickup trucks, and passenger vans fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 135, "Passenger Car Brake Systems." Some of these vehicles were produced with an out-of-specification brake hydro-boost housing relief valve bore. Consequently, the valve O-ring seal may fracture. Steering efforts may be slightly increased while braking or parking. Under certain driving conditions, a fractured seal may also require an increase in the applied brake pedal effort to achieve the same vehicle deceleration.
Dealers are to replace the hydro-boost relief valve. The manufacturer has reported that owner notification is expected to begin during the second quarter of 2004. Owners may contact Cadillac at 1-866-982-2339; Chevrolet at 1-800-630-2438; GMC at 1-866-996-9463; or Hummer at 1-866-486-6376.
