-
Axle assembly (power train)
The differential oil of the transaxle is lost over time due to evaporation. Low oil levels cause premature bearing and gear wear and eventual failure of the differential.
Remedy: Drain and replace the differential gear oil with oil having higher performance characteristics.
Model years: 1985, 1986, 1987, 1988, 1989, 1990, 1991
-
Vehicle speed control
Excessive wear of idle stabilizer could cause idle fluctuations.
Remedy: Replace idle stabilizer.
Model years: 1985, 1986
-
Buckle assembly (seat belts)
Rear or front right seat belt locks may not properly engage. Consequence of defect: seat belts could separate in event of heavy brake application or impact and thus subject passengers to injury.
Remedy: Replace seat belts, as necessary.
Model years: 1986
-
Hoses, lines/piping, and fittings (service brakes)
Under adverse weather conditions, outer rubber layer of brake hoses may become brittle and develop cracks. Consequence of defect: cracks could lead to loss of brake fluid resulting in an increase in stopping distance and possibly an accident.
Remedy: Replace brake hoses as necessary.
Model years: 1984
-
Fuel injection system (fuel system)
The fuel pump may stop functioning without warning. This can occur because an electrical connector in the fuse panel may overheat and interrupt the electrical circuit.
Remedy: Dealer will inspect the fuse box and its connectors for corrosion, and correct where necessary. A bypass adapter to the fuel pump electrical circuit will be installed.
Model years: 1980, 1981
-
Frame and members (structure)
Rear bumper system on certain vehicles may not have been properly welded during assembly. In the event of a rear end collision, the right side bumper supportor could break loose, damage the fuel tank and allow fuel to leak.
Remedy: A reinforcement plate will be installed, if necessary, to prevent fuel tank damage. Work will be performed at no cost to owners.
Model years: 1980, 1981
-
Caliper (service brakes)
On certain vehicles, porous spots may have developed on the interior surface of the threaded hole for the brake hose during the moulding process. These spots allow brake fluid to seep from the calipers during heavy brake applications.
Remedy: Both front brake calipers will be inspected for brake fluid seepage and will be replaced, if necessary, without charge.
Model years: 1981
