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.

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.

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

Debris can get into the idle air control valve. This will restrict the air flow into the engine, causing idle speed and/or stalling when cold. The valve can be cleaned or replaced to correct this concern.

The head gasket may fail due to a defect in manufacturing of the cylinder block.

On this vehicle, the head bolts are known to pull the threads out of the engine block, allowing the head to slightly lift, and causing head gasket failure. Symptoms may include:

  • Overheating
  • White smoke from exhaust
  • Rough running conditions and/or inability to start or idle
  • White or cream colored oil on dipstick
  • Check engine light 
  • OBD Trouble Codes P2181, P0300

When the head gasket fails, the bolt holes for the head bolts must be repaired before the cylinder head can be remounted. 

This issue is not always preventable, but to help avoid it, never run the engine if the engine temperature is ever above the normal range. 

Sludge can build up in the engine because Toyota did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.

The VVT-i oil line is known to burst. This is a very large leak which covers the ground, engine, and undercarriage.

If the oil line ruptures while driving, the low engine oil message and engine oil pressure warnings will illuminate. Continued use after these warnings will result in complete engine failure due to oil starvation.

The line is known to be defective, and a revised part has been issued by Toyota, however, this revised part is known for the same issue.

To repair the issue, the line must be replaced, and the engine bay and undercarriage must be cleaned thoroughly.

The Toyota Camry with the 3.0L V6 engine has a known issue with the valves that if left unchecked, will cause burned valves and engine performance issues. 

The engine ‘breathes’ through valves that are pushed open by the camshaft, and closed by springs. When valves are closed, they seal against a valve seat. In this vehicle, the valve seat is too soft, so after the valve contacts it thousands of times, it becomes crushed. Once it is crushed, the valve can no longer make a proper seal, and the valves erode due to extreme temperature (burnt valve).

Symptoms related to this issue:

To repair the burnt valves, the cylinder head must be removed and rebuilt, which is a costly internal engine repair, however, this issue can be prevented through inspection and adjustment of valve clearances every 40,000 miles.

On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

Intermittent failure of a purge control valve in the evaporative emission system can cause the Check Engine Light to illuminate. A failed valve should be replaced to correct this problem.

 

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

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

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.
