SABERSPORT IS RECALLING 16,270 COMBINATION CORNER AND BUMPER LAMP ASSEMBLIES OF VARIOUS PART NUMBERS SOLD FOR USE AS AFTERMARKET EQUIPMENT FOR VARIOUS PASSENGER VEHICLES. THESE HEADLAMPS FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT." THESE LAMPS DO NOT CONTAIN THE REQUIRED AMBER SIDE REFLECTORS.
A BACKFIRE DURING ENGINE STARTING CAN CAUSE BREAKAGE OF THE UPPER INTAKE MANIFOLD.
THESE VEHICLES WERE ASSEMBLED WITH A MALFUNCTION ALARM, LIGHTING AND LOCKING (MALL) MODULE THAT CAN CONTAIN A DAMAGED CAPACITOR. IF THE CAPACITOR IS DAMAGED, THE "KEY IN THE IGNITION" WARNING CHIME AND THE DRIVER SEAT BELT UNBUCKLED WARNING CHIME AND INDICATOR LAMP MAY NOT WORK. THIS DOES NOT MEET THE REQUIREMENTS OF FMVSS NO. 114, "THEFT PROTECTION" AND FMVSS NO. 208, "OCCUPANT CRASH PROTECTION." IN ADDITION, OTHER CHIME REMINDER FUNCTIONS, INTERIOR LIGHTING CONTROLS, AND POWER DOOR LOCKING FEATURES ARE ALSO AFFECTED.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
