Recalls
3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Seat belts Vehicle recall #95V242000 · 1995 · 40 vehicles
What's wrong: These vehicles were built with front seat belt systems with no energy management loops and May not meet the head injury criteria requirements of fmvss no. 208, "occupant crash protection."
Why it matters: In the event of a vehicle crash, the occupants of these seats May not be properly restrained.
The fix: Dealers will replace the retractor portion of the seat belt assembly(s) with one having the newly designed energy-management twin-loop system.
Seat belts Vehicle recall #95V241000 · 1995 · 630,099 vehicles
What's wrong: If both the lap-belt and shoulder-belt energy management loops on the front seat belt assemblies release at or near the same time, acceleration forces can cause the buckle release mechanism to activate and allow the buckle to separate from the latch.
Why it matters: If the buckle released, the system would fail to provide adequate occupant restraint protection.
The fix: Dealers will remove the stitching that creates the energy management loop in the shoulder belt(s).
Visibility (wipers, glass) Vehicle recall #98V150001 · 1998 · 1,557,585 vehicles
What's wrong: Solder joints near the wiring harness connector can crack causing the windshield wipers to work intermittently.
Why it matters: This condition can result in inoperative wipers, reducing a driver's visibility, and increasing the risk of a vehicle crash.
The fix: Dealers will replace the wiper motor circuit board and cover.
