What's wrong?
The exhaust sensor on these 2011-2012 Ford F-350, F-450, and F-550 Ambulance Package trucks is part of the diesel engine control system. It reads conditions in the exhaust stream and sends that information to the engine computer, which uses the signal to manage engine operation.
Ford's filing ties the recall to an exhaust sensor problem on trucks equipped with the 6.7L diesel engine. When the sensor problem occurs, the truck experiences a loss of power followed by an engine stall. In an ambulance package vehicle, that failure path matters because the engine has to keep running reliably during transport and emergency use.
There is no warning sign before failure. The first thing an owner or driver notices is the loss of power, followed by the stall described in NHTSA campaign 13V535.
Who's affected?
Covers F-350, F-450, and F-550 trucks from the 2011 and 2012 model years, all tied to the engine component.

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?
An unexpected engine stall increases crash risk. For an ambulance, a stall during patient transport also increases injury risk for the patient. If your VIN is included, contact a Ford dealer and arrange the recall repair before returning the vehicle to service. Repair will be free at any franchised Ford dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2012 Ford F-350, F-450, or F-550 Ambulance Package vehicle is included in this recall.
- Contact a franchised Ford dealer with recall number 13V535 and ask whether the free exhaust gas temperature sensor replacement is open for your VIN.
- Schedule the exhaust gas temperature sensor replacement that fixes the loss-of-power and engine-stall risk.
- Bring Ford's owner notice if you have it. If not, give the dealer recall number 13V535.
- Avoid using the ambulance for patient transport until the repair is complete if the vehicle loses power or stalls.
What happens at the repair
Ford's listed remedy is a replacement of the exhaust gas temperature sensor. Once the dealer repair is available, a Ford technician will remove the affected sensor and install the replacement sensor at no charge under the recall. The owner notice process began on November 25, 2013, so the service desk can look up campaign 13S10 and confirm the repair path for an included VIN.
