2002 Toyota Prius Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2002 Toyota Prius

The fuel gauge may read incorrectly. Our technicians tell us there is a recalibration procedure which should be performed to correct this issue.

A no start or loss of power issue may develop if debris falls into the mass air flow sensor when changing or inspecting the air filter. Care should be taken when changing of replacing the air filter in order to avoid this issue.

The hybrid transmission may fail prematurely. Our technicians recommend changing the transmission fluid every 30K miles in order to help prolong transmission life. There is a small square pan on the bottom of the transmission which should be removed to allow more fluid to drain. This service recommendation is over and above the Toyota recommendation to "check" the transmission fluid every 30k miles.

Best car I ever had! Extremely reliable. First repair (other than scheduled maintenance) was at 150,000 miles when the rear wheel bearings were replaced. The car now has 180,000 miles and still drives like new (no squeaks or rattles, tight steering and suspension) and still gets 42-46 MPG. I will buy another Prius in a heart beat but this one still runs so good that I just can't part with it.
