2009-2013 Ford F-350-550 Recall 14V378: PTO Oil Leak

RN
Reviewed by the RecallNotify editorial team
Published June 2, 2026

Recall 14V378 affects 7 Jomac-modified 2009-2013 Ford F-350, F-450, and F-550 trucks for PTO oil leaks. Repair is free at a franchised Ford dealer.

Jomac is recalling 7 modified 2009-2013 Ford F-350, Ford F-450, and Ford F-550 Super Duty vehicles under recall 14V378 because oil from the PTO pressure switch can leak onto a thermal blanket covering the exhaust. Exhaust heat and soaked oil raise the risk of fire, and the Ford dealer repair will be free once Jomac makes it available.

What's wrong?

The Muncie Power Products PTO assembly on these Jomac-modified 2009-2013 Ford F-350, Ford F-450, and Ford F-550 trucks sends power from the truck drivetrain to auxiliary work equipment. The PTO pressure switch is part of that system, and it helps control or monitor oil pressure while the PTO is in use.

In the affected trucks, oil can leak from the PTO pressure switch. That leak puts oil onto a thermal blanket covering the exhaust, which is an area built to handle heat, not leaked oil. The problem is the location of the leak as much as the leak itself.

There is no warning sign before failure. An owner does not get a specific light, sound, or drivability change in the source record before oil reaches the exhaust blanket.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.

What's the safety risk?

Leaking oil can soak into the thermal blanket over the exhaust. When that blanket heats up, the oil-soaked material increases the risk of fire. Schedule the repair soon, and call the dealer if you see oil under the vehicle or smell burning oil. Repair will be free at any franchised Ford dealer once available.

What should I do?

  1. Check your VIN to confirm your 2009-2013 Jomac Ford F-350, Ford F-550, or Ford F-450 is included in this recall.
  2. Contact a franchised Ford dealer to schedule the free pressure-switch-kit repair that moves the oil-leak source away from the exhaust.
  3. Bring the recall notice if Jomac mailed one. If not, reference recall number 14V378 when you call.
  4. Avoid parking near dry grass or other heat-sensitive areas until the repair is complete, since leaking PTO oil can reach the exhaust blanket.
  5. Call Jomac customer service at 1-800-755-4488 with questions about this upfitter recall.

What happens at the repair

At the dealer, a Ford technician installs a new pressure switch kit for the Muncie Power Products PTO assembly. The kit moves the pressure switch away from the exhaust system, which addresses the oil leak path described in Jomac recall 14V378. Because the remedy status is not confirmed, confirm parts and instructions with the Ford service desk before arranging the visit. Once the dealer repair is available for your VIN, parts and labor are free under the recall.

Frequently asked questions

What is recall 14V378?

Recall 14V378 covers 7 2009-2013 Jomac-modified Ford F-350, Ford F-450, and Ford F-550 Super Duty vehicles with certain Muncie Power Products PTO assemblies. Oil can leak from the PTO pressure switch onto a thermal blanket covering the exhaust, increasing fire risk.

What should I do if my 2009-2013 Jomac Ford F-350, Ford F-450, or Ford F-550 is on this recall?

Check your VIN to confirm your specific truck is included in recall 14V378. If it is, contact Jomac customer service at 1-800-755-4488 or a franchised Ford dealer and ask for the pressure switch kit installation. The repair is free.

Is the recall repair free?

Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and Jomac's remedy states that dealers will install the new pressure switch kit free of charge. The kit moves the switch away from the exhaust system.

What is the safety risk?

The safety risk is fire. Leaking oil can soak into the thermal blanket covering the exhaust, and exhaust heat can ignite the oil-soaked material. If your VIN is included, arrange the free pressure switch kit repair before continuing regular use.

What if I bought this Jomac-modified Ford truck used?

The free recall repair still applies. Recall eligibility follows the VIN, not the current owner or where the truck was purchased. Check your VIN, then reference recall 14V378 when you call Jomac customer service or the dealer.
