Recalls

2 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Seats Vehicle recall #92V124000 · 1992 · 319,181 vehicles

What's wrong: The power seat or recliner wiring harness can be pinched or can chafe on the seat frame or spring support rod, wearing through the wire insulation and causing an electrical short.

Why it matters: The high current caused by the electrical short welds thecircuit breaker elements together in the closed position, leaving the circuitunprotected and generating sufficient heat to burn the wire insulation andignite the seat cushion material.

The fix: Repair any abraded wiring and reroute the wiring harness using a wiring harness clip.

Seat belts Vehicle recall #95V173000 · 1995 · 2,216,325 vehicles

What's wrong: These vehicles were assembled with rear outboard safety belt anchorages that May not withstand the required load. This does not comply with fmvss no.210, "seat belt assembly anchorages."

Why it matters: Consequence of non-compliance: in a collison, stress can cause the attachment metal to tear and allow the anchorage to separate from the body of the vehicle. The safety belt May not protect an occupant in the event of a vehicle crash.

The fix: Dealers will replace the existing anchor bolts with a new shoulder bolt and thread locking adhesive. Additionally, noise control patches will be applied at each anchorage.
