What's wrong?
The engine oil cooler tube assembly on affected 2015-2017 Ford Mustang vehicles with 5.2L engines is part of the oil circulation system. It carries engine oil between the engine and the cooler, where heat is pulled out of the oil before it returns to protect moving engine parts. The hose and metal tube have to stay locked together while oil is hot and under pressure.
On these Mustangs, the hose can separate from a crimp joint in that assembly. The crimp is the squeezed metal collar that holds the hose onto the tube. Ford's investigation found the crimp jaw location and hose insertion depth were not controlled well enough during assembly, so the joint did not grip the hose as designed. When the hose separates, engine oil leaks out.
There is no warning sign before failure. An owner first sees the problem after the hose has separated, such as oil under the vehicle or evidence of an engine oil leak.

What's the safety risk?
A sudden engine oil loss can cause engine failure, increasing crash risk. Oil leaking onto an ignition source also raises fire risk. There is no warning sign before failure, so schedule the repair soon and stop using the vehicle if you see an active oil leak. Repair is free at any franchised Ford dealer.
What should I do?
- Check your VIN to confirm your 2015-2017 Ford Mustang is included in this recall.
- Contact a franchised Ford dealer to schedule the free engine oil cooler tube assembly replacement that fixes the hose separation and oil leak.
- Bring the recall notice if Ford sent one. If not, reference recall number 16V779 when you call.
- Avoid driving with an active oil leak, and contact the Ford dealer before moving the car.
- Keep the car away from ignition sources if you see oil leaking until the dealer gives repair guidance.
What happens at the repair
At the dealer, a Ford technician replaces the engine oil cooler tube assembly, including the hose connection that can separate and leak oil. The recall repair is free, with parts and labor covered. Ford is not offering a separate reimbursement program because the original warranty program provided a free repair for this concern. If you have prior repair paperwork, ask the service desk how the warranty coverage applies.
