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.
