P0524 on Ford by model: symptoms, diagnosis and fix
A small population of 2023 Explorers with the 2.3L EcoBoost engine may have a torn or cut turbocharger oil supply line O-ring. The damaged O-ring can let pressurized engine oil escape and contact a hot engine, increasing the risk of an under-hood fire; oil loss can also cause an engine stall and loss of motive power. Ford recalled the affected units (built at Chicago Assembly July 25-Aug 3, 2023; ~10 vehicles) in August 2023.
Common Symptoms
- Oil-pressure warning light
- Smoke from engine bay
- Burning oil smell
- Oil leak under engine
- Engine stall / loss of power
How to Fix
Covered under NHTSA Recall 23V597: dealers replace the turbocharger oil supply line assembly free of charge. Owners are advised to stop and shut off the engine as soon as safe if an oil-pressure warning light illuminates or smoke is seen from the engine compartment, then arrange the recall repair.

The 1.0L EcoBoost uses a 'wet' timing belt that runs submerged in engine oil. When oil is old, over-extended, or not to Ford's WSS-M2C948-B spec, the belt's rubber breaks down and delaminates ('pilling'). Shed fragments migrate through the sump and clog the oil pump pickup screen, causing loss of oil pressure and catastrophic engine failure. NHTSA opened an investigation after dozens of complaints of low oil pressure followed by power loss on 1.0L EcoBoost vehicles. Ford originally quoted a very long belt interval (10 yr / 150k mi) but real-world failures pushed independent shops to recommend ~6 yr / 60k mi replacement. Failure can also destroy the belt-driven oil pump and cause the crank pulley to shed the belt.
Common Symptoms
- Oil pressure warning light
- Loss of engine power / stalling
- Rattling or ticking timing noise
- Oil contaminated with rubber flakes
- Engine seizure in severe cases
- Rough running before failure
How to Fix
Replace the wet timing belt on a shortened interval (roughly every 6 years / 60,000 miles), and always use only the Ford-specified low-additive oil. At belt replacement, drop the sump and clean/replace the oil pump pickup screen and inspect for rubber debris. If low oil pressure or belt debris is found, replace the oil pump and pickup and flush the system; severe cases with bearing damage need engine replacement.

Select 2023-2025 Escape (and 2025 Bronco Sport) vehicles with the 1.5L EcoBoost engine left the cylinder-head supplier (Nemak Monterrey) with insufficient heat treatment, leaving the head hardness below specification and the ball plugs without enough retention force. During operation a ball plug can be ejected from the cylinder head, causing an oil leak that can ignite a fire and/or lead to rapid oil loss and engine seizure with loss of motive power. The affected population is small (roughly 400 engines), tied to supplier power failures that interrupted heat treatment, but the failure mode is severe. This is distinct from the earlier 2.5L hybrid engine-block-breach fire recall.
Common Symptoms
- Engine oil leak / oil spots under the vehicle
- Burning oil smell or smoke from the engine bay
- Low oil pressure warning light
- Loss of engine power or sudden engine seizure
- Ticking/knocking before failure
How to Fix
Under NHTSA recall 25V372 (Ford 25S61), dealers inspect and replace the cylinder head assembly as necessary, free of charge. Owners who see oil leaks, smell burning oil, or get low-oil-pressure warnings should stop driving and contact a Ford dealer. Repairs are free under the recall.

Ford recalled approximately 6,500 US-market 2015-2017 Shelby GT350 and GT350R Mustangs (built Feb 2015-Aug 2016) because the engine oil cooler tube assembly was crimped with insufficient force, allowing a hose to separate from the tube and leak oil. A sudden loss of oil can cause catastrophic engine failure, and leaked oil near an ignition source raises fire risk - particularly serious on a track-focused car run at sustained high RPM. This is separate from the GT350's broader track-overheating complaints; it is a defined safety recall with a free remedy.
Common Symptoms
- Oil leak / oil on the underbody near the cooler lines
- Rapidly dropping oil pressure or low-oil warning
- Smoke or burning-oil smell after hard driving
- Oil spots under the front of the car
How to Fix
Check the VIN against NHTSA campaign 16V779000 (Ford recall 16S40). The dealer replaces the engine oil cooler tube assembly at no charge. Owners should verify completion before any track use; running the engine with a separated cooler line can destroy the Voodoo motor.

The Ford Transit aluminum oil pan is prone to drain plug thread stripping, especially in vehicles serviced at quick-lube shops or with frequent oil changes. The aluminum pan threads are softer than the steel drain plug, and over-torquing or cross-threading during routine oil changes permanently damages the threads. Once stripped, the drain plug leaks oil or falls out entirely, potentially causing catastrophic engine damage from oil starvation.
Common Symptoms
- Oil dripping from drain plug area after oil change
- Drain plug feels loose or wobbles
- Oil spots on ground under engine
- Low oil pressure warning after recent service
- Drain plug cannot be tightened properly
How to Fix
For minor thread damage: install a Time-Sert or Helicoil thread repair insert (M14x1.5 for most Transit models). This is a permanent repair that is actually stronger than the original threads. For severe damage: replace the oil pan ($200-400 for the pan plus 2-3 hours labor). Prevent recurrence by always hand-threading the drain plug first, then torquing to exactly 20 ft-lbs (not more). Use a new crush washer at every oil change.

Certain 2024-2025 F-150s built with the 3.5L GTDI (EcoBoost) V6 left the plant with a misaligned engine block cup plug (freeze/core plug). The plug can push out or leak, causing a rapid — not seeping — loss of engine oil. Ford issued two campaigns: NHTSA 24V851000 and NHTSA 25V198000 (Ford 25S30, 4,356 vehicles, also covering 2024-2025 Expedition and 2024 Navigator). Losing oil pressure at speed can seize or stall the engine, and oil sprayed onto hot exhaust components is a fire risk.
Common Symptoms
- Sudden large oil leak or oil puddle under the front of the engine
- Low oil pressure warning or oil light
- Burning oil smell / smoke from the engine bay
- Engine stall or seizure
How to Fix
Check the VIN against both NHTSA 24V851000 and 25V198000. Dealers inspect the engine cup plug alignment and replace the plug free of charge; letters for 25S30 were mailed May 22, 2025. If you see a sudden large oil puddle, oil smoke, or the low-oil-pressure warning, stop driving and have the truck towed — continuing to run it turns a free plug replacement into an engine replacement.

Frequently asked questions
What does P0524 mean on a Ford?
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 Ford it is documented across 6 models: Explorer, Fiesta, Escape, Mustang, Transit, F-150.
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 Ford?
Published repair estimates on Ford range from $50 to $8,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
