Problem Reports

Some engines may experience a cold engine knock that lasts for three to five minutes after start-up, which is often misdiagnosed as a valve lifter noise. This noise is commonly not an indication of a failure and should not be a reliability or durability concern.

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.

Excessive oil consumption—defined as more than one quart per 1,000 miles (on vehicles with less than 50,000 miles) or more than one quart per 750 miles (on vehicles with more than 50,000 miles)—is common. Replacing the valve guides with an updated version should fix the problem.

A squeaking noise from the exhaust may be caused by a worn sealing ring between the exhaust manifold and the exhaust pipe.

An erratic or intermittent rough idle during the first 3 minutes of engine operation my be caused by a faulty idle air control motor.

Fuel injectors or their o-rings may leak fuel causing the engine to burn too much fuel.

Various driveability concerns can be caused by deposits on the back of the intake valves. Fuel injector cleaner has shown reasonable results cleaning light deposits.

A dirty throttle body can cause a low idle condition resulting in a stalling condition.

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.

Improper fuel pressure or fuel pressure fluctuation may be cause by a faulty fuel pump module.

A squeak noise when shifting out of gear may develop where the shift cable attaches to the gear shift lever. Our technicians tell us the shifter assembly must be replaced to correct this condition.

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 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.

A poor connection at the rear load leveling or air suspension relay can cause the rear of the vehicle to sag intermittently. Our technicians tell us that the connector can be secured at the relay using a tie strap.

The brake pedal may not return to its fully released position causing the brake lights to stay on. If no brake pedal return spring is in stalled there is a spring kit available. If the brake pedal return spring does not correct the problem the actuator piston should be replaced.

A hesitation on acceleration may be caused by a plugged EGR valve back pressure tube. EGR valve replacement is not generally required.

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