The car seems to go out of alignment on all four wheels frequently. I've purchased an unlimited alignment plan from a local auto service provider and I get it done every month or so. It's always out, sometimes significantly.

I had the rear adjusters replaced since they had rusted to the point that they couldn't be turned anymore.

A loss of power on the freeway may due to an internally leaking fuel pulsation dampener. This commonly occurs on higher mileage vehicles.

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.

At 125,000-150,000 miles, the Master Cylinder may need replacing. It is critical to adjust the brake pedal to Master Cylinder pushrod clearance or the brakes will drag and over heat.

Some of the 4 and 6 cylinder engines have had the problem of the crankshaft pulley bolt coming loose. This will make a rattling noise as the engine idles. Our technicians tell us that the pulley bolt should have a thread locker applied and then retorqued. 

The Ignition Coil, pick-up coil, and radio noise suppressors inside the Distributor are prone to failure. Our technicians recommend to replace the distributor with a complete genuine Toyota distributor if any of its components fail.

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 the range of the adjuster may be lengthened by elongating the slot where the spring attaches by 2-3 mm to remedy this problem.

The power windows and mirrors stop working because of a problem with an electrical junction block—where power from the battery is distributed to that system.

Toyota issued a recall on certain models with automatic transmissions due to brake booster performance. Toyota will replace the brake booster as needed under warranty.
This car has occasional problems with the system that controls polluting emissions from evaporated gasoline.

Some engines have had the problem of the crankshaft pulley bolt coming loose. This will make a rattling noise as the engine idles. Our technicians tell us that the pulley bolt should have a thread locker applied and then retorqued.

Occasionally, the mass air flow sensor can go lean and set a code P0170 for fuel system lean. This in not an oxygen sensor problem. If there are no vacuum leaks, the mass air flow sensor may need to be replaced. Our technicians remind us to use a factory part because the aftermarket rebuilds are very inconsistent.

A code P0773 may occur at higher mileages which indicates that the 3-way lock-up solenoid may be defective and may require replacement.
In some vehicles, the automatic transmission over heat light may come with sustained highway driving or driving at a sustained speed. Our technicians tell us that flushing the transmission and changing from Dextron lll to Dextron ll can help remedy this problem.

Front brake rotors can wear causing a pulsation felt in the brake pedal. Our technicians tell us this condition is best corrected by replacement of the front rotors and brake pads.
