Complaint history

When NHTSA received these reports. Changes in reporting alone do not establish a change in failure rates.

Problems owners report

Listed groups have at least 3 complaints. The page includes the 20 largest groups plus any additional flagged groups; some complaints are not assigned to a group.

AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.

Recalls

• NHTSA recall #96V149000August 2, 199613,900 vehicles affected

  service brakes, hydraulic: power assist: vacuum: hoses, lines/piping, and fittings

  Oil mist contained in the engine intake air Can collect over time in the brake vacuum check valve preventing the check valve from opening at the specified pressure reducing power assist to the brakes.

  Brake performance Can be diminished increasing the risk of a vehicle accident.

  Remedy

  Dealers will replace two vacuum hoses, including the check valve, with modified hoses.

• NHTSA recall #95V069000March 30, 199513,400 vehicles affected

  fuel system, gasoline: delivery: hoses, lines/piping, and fittings

  Residual engine heat Can cause premature deterioration of the fuel hose causing the hose to leak. Also, removing and reinstalling the deteriorated fuel hoses increases the likelihood of a leak.

  This condition Can result in an engine compartment fire.

  Remedy

  Dealers will install an additional control unit for the electric cooling fan. The fan will then activate after the engine is turned off when the coolant exceeds a specified temperature. The fuel hoses will also be replaced with revised hoses.

• NHTSA recall #94V094000May 11, 199412,316 vehicles affected

  engine and engine cooling: cooling system

  The radiator cap pressure relief valve release pressure is set too high. This Can cause the coolant to reach temperatures that exceed the thermal design limits of some components of the coolant system. Should this occur, engine coolant Can leak collect on top of the engine.

  If engine coolant leaks onto the hot engine exhaust manifold from the top of the engine, an engine compartment fire Can result.

  Remedy

  Dealers will inspect the vehicles and if any vehicle exhibits coolant leakage or if the coolant level has dropped to the point where the coolant loss would be sufficient to trigger the coolant level warning system, components potentially subject to deterioration from overheating would be replaced. These parts include the water pump bearing housing, the water level sensor and radiator upper hose, the thermostat gasket, and all water hoses located above the engine. In addition, all vehicles in which those components are replaced would also have the cooling system and other systems that carry flammable liquids checked to make certain that engine overheating had not caused any problems in those systems. Any identified problems will be repaired. The radiator cap, filler cap, and filler cap body of all recalled vehicles will be replaced by newly designed parts.
