1994 Buick Roadmaster Base Review

Summary: DEFECTIVE LOWER CONTROL ARM BALL JOINT ATTACHMENT NUTS WERE NOT PROPERLY TORQUED AND CAN LOOSEN.

Consequence: IF THE LOWER CONTROL ARM BALL JOINT LOOSENS, FATIGUES AND SEPARATES FROM THE FRONT SUSPENSION KNUCKLE, IT COULD CAUSE LOSS OF VEHICLE CONTROL.

Remedy: DEALERS WILL INSPECT BOTH FRONT LOWER CONTROL ARM BALL JOINT ATTACHMENT NUTS FOR PROPER TORQUE. IF THE BALL JOINT HAS LOOSENED FROM THE KNUCKLE, BOTH THE BALL JOINT AND THE KNUCKLE WILL BE REPLACED.

Summary: THESE VEHICLES FAIL TO CONFORM TO FMVSS NO. 124, "ACCELERATOR CONTROL SYSTEMS." AT LOW TEMPERATURES, EXCESSIVE FRICTION CAN OCCUR IN THE ACCELERATOR PEDAL ASSEMBLY.

Consequence: CONSEQUENCE OF NON-COMPLIANCE: IN THE EVENT OF A FAILURE OF THE TROTTLE RETURN SPRING, IF THERE IS EXCESSIVE FRICTION IN THE PEDAL ASSEMBLY, THE ENGINE SPEED MAY NOT RETURN TO IDLE INCREASING THE POTENTIAL FOR A VEHICLE CRASH.

Remedy: DEALERS WILL REPLACE THE ACCELERATOR PEDAL ASSEMBLY.

Summary: THE FUEL TANK ATTACHMENT STRAP FASTENERS WERE NOT PROPERLY TIGHTENED. THE FASTENERS CAN COMPLETELY DETACH, EVENTUALLY ALLOWING THE FUEL TANK TO SAG AND THE BOTTOM OF THE TANK TO STRIKE THE ROADWAY.

Consequence: THIS CAN RESULT IN A FUEL TANK LEAK AND FIRE IF THE LEAKING FUEL IS EXPOSED TO A SOURCE OF IGNITION.

Remedy: DEALERS WILL RETIGHTEN THE FUEL TANK STRAP FASTENERS.

Summary: PAINT ON THE WHEEL MOUNTING SURFACES CAN ACT AS A SHIM BETWEEN THE WHEEL AND THE ROTOR/DRUM. AS THE VEHICLE IS DRIVEN, THE WHEEL IMBEDS INTO THE PAINT, LOOSENING THE LUG NUT AND CAUSING A LOSS OF CLAMP LOAD.

Consequence: ONCE CLAMP LOAD IS LOST, ALL TIRE LOADS ARE TAKEN BY THE WHEEL STUDS RESULTING IN A FRACTURE OF THE WHEEL STUDS. THIS COULD CAUSE THE WHEEL TO SEPARATE FROM THE VEHICLE AND COULD RESULT IN A VEHICLES CRASH WITHOUT PRIOR WARNING.

Remedy: DEALERS WILL CLEAN THE WHEEL MOUNTING SURFACES FOR ALL FOUR WHEELS. ALSO, THE WHEEL STUDS WILL BE INSPECTED FOR DAMAGE AND WILL BE REPLACED AS NECESSARY.

Summary: THE ENGINE OIL COOLER INLET HOSE MAY HAVE BEEN INSTALLED TOO CLOSE TO THE STEERING GEAR CAUSING CHAFING. THE CHAFING CAN EVENTUALLY WEAR THROUGH THE HOSE'S PROTECTIVE SLEEVE RESULTING IN ENGINE OIL LEAKING ONTO THE ENGINE.
