P0524 on Hyundai by model: symptoms, diagnosis and fix
The 3.8L Lambda V6 in the Entourage is affected by the same connecting rod bearing failure issue that plagued early Lambda engines across the Hyundai/Kia lineup. Manufacturing debris left in the oil passages can restrict oil flow to the connecting rod bearings, causing premature bearing wear and eventual rod knock. Hyundai extended the engine warranty to 15 years/200,000 miles under a settlement. The issue typically manifests between 80,000-150,000 miles with a knocking noise from the lower engine.
Common Symptoms
- Knocking or tapping noise from lower engine
- Noise worsens with engine speed
- Oil pressure warning light illuminated
- Metal shavings in oil during oil change
- Engine seizure (advanced failure)
How to Fix
If the engine is knocking, it requires a replacement engine. Check with a Hyundai dealer for coverage under the extended engine warranty (15 years/200,000 miles). Hyundai will perform an oil consumption test and bearing inspection. Keep all oil change records — they are required for warranty claims. If covered, Hyundai replaces the engine with a remanufactured unit at no cost.
Owner tips & cautions
- TipContact your Hyundai dealer about the extended engine warranty (15 years/200,000 miles) — engine replacement is covered at no cost for affected vehicles
- TipKeep ALL oil change receipts — Hyundai requires proof of regular maintenance for warranty engine replacement
- WarningStop driving immediately if you hear engine knocking — continued driving with bearing failure causes catastrophic rod through the block, voiding the warranty

Frequently asked questions
What does P0524 mean on a Hyundai?
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 Hyundai it is documented across 1 model: Entourage.
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.
How much does it cost to fix P0524 on a Hyundai?
Repair costs vary widely with the root cause and Hyundai model; each issue on this page carries its own estimate where one is published.
