2008 Lexus RX350 Problems
RepairPal has identified the most common problems with the 2008 Lexus RX350 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The Check Engine Light may illuminate with codes stored indicating a fault with the variable valve timing system. Our technicians tell us improved camshaft timing oil control valves are available which can correct this issue.
The Check Engine Light may illuminate with a fault code P0505 stored. Our technicians tell us that this fault can be caused by a failed electronic throttle body assembly which will require replacement.
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.
Our technicians tell us that some navigation system problems may be corrected by installing an updated navigation map disc.
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.
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.
