Toyota Avalon Problems

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.

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 6 cylinder engines have a tendency to leak oil from the valve cover gaskets, especially the one near the firewall.

As part of normal operation of the air conditioning system, condensation will accumulate in the condenser housing behind the dashboard. A drain is incorporated so that excess water can drain out. This drain hose can become plugged, the accumulated water can leak onto the airbag control module. This can result in an electrical short in the control module. If this were to occur the airbags could become disabled or deploy unexpectedly. Improper airbag operation increases the risk of personal injury and/or a crash. The power steering assist could also become inoperable resulting in increased steering effort. Dealers will seal the air conditioning condenser housing and install a protective cover on the airbag control module to correct this concern.

An electrical short can develop in the windshield wiper switch assembly. As a result, the wipers may not function as expected. If the driver's visibility is reduced the risk of a crash increases. Dealers will replace the wiper switch assembly in affected vehicles to correct this concern.

The amount of adhesive applied between the inner and outer parts of the crankshaft pulley may be inadequate. If this is the case, the outer ring may become misaligned and/or not properly rotate with the inner ring, causing an abnormal noise and/or illumination of the Check Engine Light. In some cases, the power steering belt could come off resulting in a loss of power steering assist, increasing the risk of a crash. Dealers will inspect the crankshaft pulley and replace it if necessary.
