P0524 on Kia by model: symptoms, diagnosis and fix
The Cadenza's 3.3L Lambda II GDI V6 is covered under the Hyundai/Kia engine settlement for connecting rod bearing failure. Manufacturing debris in the crankshaft oil passages can restrict oil flow to the connecting rod bearings, causing premature wear and eventual engine seizure. Kia extended the engine warranty to 15 years/150,000 miles. The issue typically manifests as a knocking noise from the bottom end of the engine, often preceded by an illuminated oil pressure warning light.
Common Symptoms
- Knocking noise from lower engine that increases with RPM
- Low oil pressure warning light
- Check engine light illuminated
- Metal particles visible in oil during oil change
- Engine stalling or seizing
How to Fix
Contact a Kia dealer immediately for inspection under the extended warranty (15 years/150,000 miles). Kia performs a rod bearing clearance test and inspection. If the bearings are worn, Kia replaces the engine at no cost with a remanufactured unit. Keep all oil change records as proof of maintenance — they are required for warranty claims.
Owner tips & cautions
- TipCheck with Kia dealer about the 15 year/150,000 mile extended engine warranty — engine replacement is free for covered vehicles
- TipKeep ALL oil change receipts in the glove box — Kia requires proof of regular oil changes for warranty engine replacement
- WarningStop driving immediately if you hear knocking — continued driving can cause the rod to punch through the engine block, voiding warranty coverage

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