Most reported Geo problems

 

Verified for the Geo Tracker

An engine oil leak may develop from the front crankshaft seal due to hardening of the rubber seal. There is a revised seal and sleeve available to correct this concern. Our technicians tell us that changing the oil every 3000 miles may help prolong seal life.

At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

The ignition coil inside the distributor may fail. Our technicians tell us this may result in a hesitation on acceleration, especially when the vehicle is warming up on cold, rainy days. The pickup coils inside the distributor can also fail and cause a no-start condition. There have also been some failures of the radio noise suppressors inside the distributors, which can short out. Our technicians recommend replacing the whole distributor with a complete, genuine Toyota distributor if any of its components fail.

The engine mount on the passenger side of the car can wear out on cars with high mileage. This will put extra stress on the other mounts and the faulty mount will need to be replaced.

A condition may develop where the accelerator pedal sticks and is not smooth. This can be caused by carbon build up on the throttle shaft or throttle body cleaner was used which removed the special coating on the throttle shaft. Our technicians tell us that if this is the case the throttle body should be replaced.

The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.

If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.

The brake pedal may pulsate on apply due to warped brake rotors. This condition is commonly caused by uneven lug nut torque. Proper lug nut torque is recommended to try and avoid this concern.

Front brake rotors can wear causing a pulsation felt in the brake pedal. Our technicians often recommend replacement of the front rotors and brake pads as the best option to correct this condition.

You may be able to prevent automatic transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned, the transmission system should be completely flushed.

At higher mileages, an anti-lock brake system wheel speed sensor may wear out and illuminate the ABS warning light. It is recommended to replace the sensor with a factory part and be sure to clean all rust and debris from the mounting area because the mounting distance is critical. Failure to do so may result in the new sensor setting false trouble codes.

Over the time the exhaust gas recirculation (EGR) system may become plugged with debris, the oxygen sensor may also be getting slow or 'lazy' around this time. When servicing or cleaning  the EGR system, it is a good idea to replace the oxygen sensor because it works in tandem with the EGR system.

Front brake rotors can wear causing a pulsation felt in the brake pedal. Our technicians tell us this condition is best corrected by replacement of the front rotors and brake pads.

The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
