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.

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.

Safety investigations

NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect, and it is not a recall.

PE88061ClosedPreliminary Evaluation

SEAT TETHER FAILURE

Opened Jun 21, 1988
Closed Sep 12, 1988

SUMMARY: TRUCK DRIVER REPORTS SEAT TEATHERS ARE NOT PROPERLY ADJUSTED AT FACTORY, ALLOWING SEAT TO HINGE FORWARD IN A COLLISION. TEATHERS ACT AS RESTRAINERS, AND IF IMPROPERLY ADJUSTED SEAT BELT IS USELESS AS IT IS ATTACHED TO THE SEAT. DURING SUDDEN DECELERATION OR COLLISION THE WHOLE ASSEMBLY HINGES FORWARD ALLOWING POSSIBLE FACIAL CONTACT WITH THE WINDSHIELD.===
