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.

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.

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.

I quickly found out that this was one of the most reliable cars ever made. After reading this and other forums, I'm excited to get this little...

Had the transmission replaced at around 100,000 when the after drive ran dry (most auto dealers do not check this for fluid, one even told me it didn't have an afterdrive!)Has had new timing belt and numerous starters etc. But this car is incredibly reliable.
