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