P0524 on Chevrolet by model: symptoms, diagnosis and fix
GM recalled roughly 597,630 trucks and SUVs (NHTSA recall, 2025) — including 2021-2024 Silverado 1500 with the 6.2L L87 V8 — for connecting rods and/or crankshafts that may have manufacturing defects (debris in oil passages or out-of-spec parts). Affected engines can seize or knock and suddenly lose propulsion, with documented fire and crash allegations. GM's tally tied to the recall logged about 28,000 complaints, including ~14,300 alleging loss of propulsion. The remedy splits vehicles into two groups: those that fail inspection get a full engine replacement, while those that pass switch from 0W-20 to thicker 0W-40 oil plus a revised service procedure. NHTSA opened a follow-up engineering analysis into post-recall L87 failures, and a class action is pending — this is currently the highest-profile, highest-demand Silverado issue.
Common Symptoms
- Engine knocking or rod knock
- Sudden loss of power / loss of propulsion while driving
- Engine stall and no-restart
- Low oil pressure warning
- Metal debris in oil
- Burning smell or smoke
How to Fix
Check VIN against NHTSA recall and have the dealer perform the recall inspection. Engines that fail inspection receive a free engine replacement; engines that pass receive an oil change to 0W-40 and updated oil-fill-cap/owner guidance. If you experience knocking, a sudden power loss, or low oil pressure, stop driving and contact the dealer — continuing to drive risks total engine destruction and fire.

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