Geo Prizm Problems
RepairPal has identified the most common problems with the Geo Prizm as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.Refine by vehicle
On vehicles with a manual transmission, worn shift bushings can cause the transmission to pop out of gear, especially when coasting down in 1st or 2nd gear. Replacing all the shift linkage bushings is pretty straight forward and not expensive and will commonly correct this concern.
At 125,000-150,000 miles, the Brake Master Cylinder may need replacing. When replacing the master cylinder, it is critical to adjust the brake pedal to master cylinder pushrod clearance or the brakes can drag and overheat.
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 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.
A transmission fault code of P0770 or P0773 may occur at higher mileages which indicates that the 3-way lock-up solenoid has failed and will need replacement.
A rough idle and even an emissions inspection failure for high HC and CO can be caused by improperly adjusted valves. Also, exhaust valves may become to tight which can lead to valve failures. Our technicians tell us that regular valve adjustment inspections are a must.
The AC Expansion Valve may develop a very slow leak or allow too much refrigerant flow which reduces cooling. Our technicians tell us that Toyota makes an updated expansion valve to resolve these problems if and when they occur.
If the vehicle develops an annoying, clunking sound when driving over bumps it is usually the struts and strut bearing plates. These may need replacing at 100,000-125,000 miles or sooner. If the noise is a more of a squeak or groan, it can be usually be eliminated by spraying a light lubricant on the suspension bushings 1-2 times per year.
