Known Problems

Low fuel pressure may be caused by a faulty fuel pump check valve.

A faulty transmission control module may fail causing the engine to stall after starting or the transmission to become stuck in 2nd gear.

Hard starting or rough idle after the vehicle is parked for a period of time may be caused by leaking fuel injectors.

Abnormal fuel pump noise may be noted.There is a revised fuel pump, wiring harness, fuel tank insulators, fuel tank straps, and fuel tank available depending on the vehicle.

Corrosion on the coolant temperature sensor wiring may cause a hard or no start condition in cold ambient temperatures.

Revised transfer and output gears are available to correct a load sensitive high frequency whine from the transaxle.
Intermittent transaxle shudder during torque converter clutch apply may be caused by transmission fluid issues. Our technicians tell us that changing the fluid and filter, driving the vehicle 10 miles and changing the transaxle fluid again and correct this issue.

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

Odors from the AC (HVAC) system may be caused by microbial growth on the AC evaporator. Our technicians recommend to keep the AC inlet free of leaves and debris and treating the evaporator and housing using a disinfectant spray.

A rattle noise may be noted from the rear brake pads which is eliminated when applying the brakes lightly. Revised rear brake pads are available to correct this condition.

Oil leaks may develop from the camshaft plug, camshaft seal, valve cover, cylinder head gasket, and distributor.

Timing belt replacement should be done at 60K intervals or sooner in very hot climates. The timing belt tensioner pulley should be replaced any time the timing belt is replaced.

The alternator belt may develop a chirping or snapping noise over time due to pulley misalignment. There is a revised alternator bracket to address this concern. If there is still an issue after the bracket has been replaced washers can be used to align the alternator pulley.
Oil leaks may develop from the valve cover gaskets, cam plugs, camshaft seals, front crankshaft seal, and the oil filler bracket.
A squeaking noise from the exhaust may be caused by a worn sealing ring between the exhaust manifold and the exhaust pipe.
