2009 Lexus RX350 ProblemsAir Conditioning Fault Due to Failed AC Amplifier
The air conditioning light may flash or an AC error message may be displayed. Our technicians tell us this is commonly due to a fault with the AC amplifier, as revised part is available to correct this concern.
The supplemental restraints system (SRS) warning light may illuminate with code B0111 and/or B0116. Our technicians tell us Lexus has several service bulletins regarding the SRS system. It is not uncommon to replace one or more airbags to correct these fault codes.
An VVT-i oil line on the Lexus RX350 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.
