2011 Toyota Avalon Problems

Check Engine Light on Due to EVAP Vapor Canister Fault

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.

Rear Window Sunshade Fails and Makes Grinding Noise

The motor for the rear window sunshade in the Toyota Avalon is known to fail. When this occurs, the sunshade will not extend down the window, and a grinding noise is heard until the motor fails as well. 

Replacement of the sunshade assembly is necessary to correct this failure, however, removing the fuse for the sunshade will stop the motor from making the irritating grinding noise. 

Massive Oil Leak and Loss of Oil Pressure

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.

We hate our 2010 Toyota Avalon (39,800 miles). The motor makes a tapping noise, sounds like a diesel truck. We have complained to dealership about this for over one year. They said there's nothing they can do about it. Leather seat was showing wear but they did replace. The quality is not what it's built up to be. There were many recalls on this car.
My 2011 toyota avalon has 9000 miles on it. At about 8000 miles I began to notice a pop in the steering collum when I would turn in either direction. The dealer stated that they would probably have to change out the steering colum assy. but would have to get authority from the toyota factory. I am still waiting.
