Known Problems

Cars equipped with an automatic transmission might experience a hesitation when accelerating. Revised software for the on board computer is available which may correct this problem. Software revisions are commonly most helpful on newer vehicles. once the mileage builds up a worn component could cause similar problems. Whenever major transmission work in performed, the transmission software should be updated as necessary.

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

The valve cover gaskets have a tendency to leak oil, especially the one near the firewall.

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. Be sure to check the condition and runout of the front wheel bearings on the 2WD and 4WD vehicles and the CV joints on the 4WD vehicles since worn wheel bearings and/or CV joints can cause the ABS trigger rings to rub against the ABS sensors and damage them.

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 proper repair for a leaking Steering Rack & Pinion is replacement with a new unit.

As the size of the Camry vehicle gets ever larger, there is a tendency to warp the front rotors. This will be felt as a shudder in the steering wheel when braking. The front rotors can be remachined, if there is sufficient material left, otherwise the front rotors will need to be replaced. It is recommended to use factory quality rotors because cheap quality rotors warp very easily and tend to squeak and squeal.

One or more motor mounts may wear out on cars with high mileage. This will put extra stress on the other mounts, and the faulty mount(s) should be replaced.

The power steering pump and power steering hoses tend to develop leaks, particularly in the V6 models.

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

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.

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.

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.
