P0524 on Kia
Engine Oil Pressure Too Low
P0524 on Kia vehicles indicates engine oil pressure too low. Au7o has documented this code across 1 Kia model — most commonly on Cadenza. 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.
Common Causes of P0524
- •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
P0524 on Kia by Model
Kia Cadenza(1 issue)
- 3.3L Lambda II GDI V6 Connecting Rod Bearing Failure2014-2020
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.

What does P0524 mean on 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 specifically, this code is documented across 1 model.
