Known Problems

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.

The Evaporative system may have problems with the vapor canister releasing charcoal pellets that plug the vent valve. Typically a Code P0441, P0442 and P0446 will be set. The key code is the P0446 which is a vent valve electrical failure. The proper repair is to replace the entire canister with all the valves as a unit. This is located on top of the fuel tank and is expensive. Our Technicians tell us that for awhile Toyota was covering these problems, but this may have changed. It would not hurt to call the dealer if this problem occurs to see if Toyota is still helping with these repairs.

Exhaust gas recirculation valve lift sensor failures have been reported.

Driving over bumps causes loud, annoying noises in the body of the car. If the noise is a groaning or creaking, it can be improved by lubricating the rubber joints in the suspension system. If the noise is a rattling sound, the problem is likely wear and tear on the upper mounting plate for one or more of the suspension struts.

The timing belt tensioners may make a rattling noise at a higher mileages. This is due to the adjustment being at its limit. Our technicians tell us that range of the adjuster may be lengthened by elongating the slot where the spring attaches by 2-3 mm to remedy this problem.
Toyota also issued a recall on the seat belts because of a faulty buckle status switch. The seat belt status switch can be replaced under the recall.

If the car will not start, the most likely problem is worn or corroded solenoid contacts in the starter. Usually, these parts can be replaced without purchasing a new starter.

The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.

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.

We recommend flushing the brake fluid every 60,000 miles because the fluid can become dirty and may cause problems in the brake system such as premature failure of the master cylinder or wheel cylinders.

Our technicians report that by 100,000 miles, the ignition key tends to wear out and should be replaced or it may not work as well in the door locks or ignition lock cylinder.
