P0524 on Lexus by model: symptoms, diagnosis and fix
The 2022+ Lexus LX uses the V35A-FTS twin-turbo V6 that is included in Toyota/Lexus campaigns for potential engine damage from machining debris and resulting main-bearing failure. Owners have reported knocking, reduced power, check-engine lights, and in some cases complete engine replacement. This is one of the most serious documented issues for the current LX because it can lead to sudden engine failure and very expensive repairs outside recall coverage.
Common Symptoms
- Engine knocking or ticking
- Check engine light
- Reduced power
- Rough running
- Metal debris in oil
- Engine failure or no-start after internal damage
How to Fix
Check VIN for open engine recall/campaign status immediately. If symptoms such as knocking, low oil pressure warnings, or misfire/limp mode appear, the vehicle should not be driven until inspected; dealers may perform engine inspection and, where required by campaign procedure, short-block or complete engine replacement. Oil filter inspection for metallic debris and oil pressure verification are key diagnostic steps.
Owner tips & cautions
- TipIf buying used, ask for oil analysis or service records showing recall completion and use of correct oil spec.

Frequently asked questions
What does P0524 mean on a Lexus?
P0524 stands for "Engine Oil Pressure Too Low." This code sets when the engine control module sees that engine oil pressure has dropped below the safe minimum threshold, based on the reading from the oil pressure sensor (or switch). Adequate oil pressure is what keeps a protective film of oil between the bearings, crankshaft, and other moving parts, so the computer treats low pressure as a serious warning. It can mean the actual pressure really is too low, or that the sensor circuit is reporting a false low value. Because true low oil pressure can quickly destroy an engine, this code should be checked immediately and the engine not run hard until the cause is confirmed. On Lexus it is documented across 1 model: LX.
What are the most common causes of P0524?
The most common causes of P0524 are: Low engine oil level, Faulty oil pressure sensor or sending unit, Worn or failing oil pump, Clogged oil pickup screen or dirty oil, Wrong oil viscosity for the engine, Worn engine bearings reducing pressure, Wiring or connector fault at the oil pressure sensor. The specific cause varies by vehicle.
