Recalls

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

Brakes (hydraulic) Vehicle recall #94V152000 · 1994 · 214,000 vehicles

What's wrong: The nuts and bolts that attach the rear brake adaptor to the axle housing flange can loosen and eventually separate. If one or more of the nuts come off the bolts, damage to the parking brake assembly or to the antilock brake system (ABS) sensor and sensor ring (if so equipped) will occur. If all four nuts on one end of the axle come off the bolts, damage to the brake hydraulic line or the parking brake cable can…

Why it matters: Occurrence of any of these conditions can result in a loss of braking capability and possible accident.

The fix: Dealers will inspect and, if needed, install new bolts. If any of the fasteners are disconnected, the parking brake and ABS components will be inspected and serviced.

Speed control / throttle Vehicle recall #07V336000 · 2007 · 3,600,000 vehicles

What's wrong: On certain pickup trucks, passenger vehicles, sport utility vehicles, and motor homes chassis, the speed control deactivation switch May, under certain conditions, leak internally and then overheat, smoke, or burn.

Why it matters: This could result in an underhood fire.

The fix: Dealers will install a fused wiring harness. Owners of the passenger cars included in this campaign will be instructed to return their vehicles to their dealers to have the speed control deactivation switch disconnected as an interim repair. As soon as repair parts are available (expected October…

Speed control / throttle Vehicle recall #08V051000 · 2008 · 225,000 vehicles

What's wrong: The affected vehicles were previously repaired using a wiring harness that is not compatible with the vehicle circuit polarity.

Why it matters: As a result, the fuse is located in the output circuit rather than in the intended input power feed circuit, and May not offer the intended protection in the event of an electrical short to ground.

The fix: Dealers will install a new wiring harness, or replace the mating electrical component. The recall began on February 18, 2008.
