Recall campaignsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

6 campaigns cover this model year — what the defect is, what it could cause, and what the remedy is

91V070000

STEERING:LINKAGES

May 1, 1991
3,673 units potentially affected
The defect: STRESSES IMPOSED ON THE LEVER DURING TURNING MANEUVERS AND/OR IMPACT INCIDENTS, SUCH AS WOULD BE CAUSED BY CURBS OR ROAD SURFACE IRREGULARITY, REDUCE THE LIFE EXPECTANCY OF THE PART. THE STEERING LEVER MAY CRACK AND EVENTUALLY THE STRESSES COULD CAUSE THE STEERING LEVER TO BREAK.

UNDER CERTAIN CONDITIONS THE STEERING SHAFT MAY DISENGAGE. CONSEQUENCE OF DEFECT: A JARRING IMPACT MIGHT CAUSE DISENGAMENT OF THE SPLINED SHAFT RESULTING IN LOSS OF STEERING CONTROL AND POSSIBLY AN ACCIDENT.

STEERING: STEERING WHEEL/HANDLE BAR

Apr 5, 1983
1,455 units potentially affected
The defect: ON THE INVOLVED VEHICLES THE FLOORBOARD OPENING AND THE STEERING COLUMN SEAL BRACKET DO NOT HAVE SUFFICIENT CLEARANCE TO ALLOW THE SHAFT TO TURN FREELY. THIS CAUSES THE PINCH BOLT TO BIND OR LOCK AGAINST THE SEAL BRACKET.
The remedy: THE HOLE IN THE FLOORBOARD WILL BE ENLARGED TO ALLOW SUFFICIENT CLEARANCE OF THE STEERING COLUMN U-JOINT PINCH BOLT, AND A NEW BRACKET AND LAMP WILL BE INSTALLED AT NO CHARGE TO OWNER.

The defect: THE FLOORBOARD OPENING AND THE STEERING COLUMN SEAL BRACKET MAY NOT ALLOW SUFFICIENT CLEARANCE FOR THE SHAFT TO TURN FREELY IN THE CENTER OF THE BRACKET/SEAL. THE PINCH BOLT IN THE COLUMN YOKE MAY BIND OR LOCK THE COLUMN AGAINST THE BRACKET, ALLOWING LITTLE OR NO WHEEL RETURN.
The remedy: DEALER WILL ENLARGE THE HOLE IN THE FLOORBOARD TO PROVIDE CLEARANCE FOR THE STEERING COLUMN U-JOINT PINCH BOLT. A NEW BRACKET AND CLAMP WILL ALSO BE INSTALLED WITHOUT CHARGE TO OWNER.

What a recall is

Safety recall
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
Safety investigation
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
