Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 1994 BUICK Roadmaster. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
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.
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.

ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS
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.
Consequence
IF THIS OCCURS, THE OIL LEAK ONTO THE ENGINE CAN RESULT IN AN ENGINE COMPARTMENT FIRE.
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.
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.

Complaints across nearby Buick Roadmaster model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.
VERIFIED EMPTY IMPORT SNAPSHOT
No exact NHTSA ODI investigation row was matched.
The checked bulk snapshot returned zero investigation action numbers for 1994 BUICK Roadmaster. That is source coverage, not proof that no issue exists or will be investigated later.

Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.
