When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2011 Ford F-550

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Vehicle Commanded Engine Shutdown

The Office of Defects Investigation (ODI) opened this RQ to investigate allegations that the scope and remedy of safety recall 13V-535 were inadequate. Recall 13V-535 was limited to a relatively small population of Ambulance Package vehicles and ODI received complaints of pickup trucks and Fire Engine Prep Package vehicles being affected by the same defect. Ford manufactured approximately 555,985 subject vehicles between February 22, 2010 and January 30, 2015 that may be affected by defective EGT sensors and Powertrain Control Module (PCM) software calibration. The subject vehicles are equippe...

The Office of Defects Investigation (ODI) is aware of 1 incident related to the alleged defect. By letter dated January 10, 2014, Almared, Inc. (doing business as A-1 Alternative Fuel Systems) has notified ODI that it has conducted a safety recall (NHTSA Recall No. 14V-040) to address a safety defect in 18 model year 2011-2012 Ford F-550 transit buses manufactured between May 2011 and April 2013. These vehicles have been altered by A-1 to contain one or more compressed natural gas (CNG) fuel containers.

Recalls on the 2011 Ford F-550

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2019420 5,327 units in Canada

Other

Issue: This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act. Safety Risk: Glass that breaks in to large pieces could create a risk of injury. Corrective Actions: The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.

Recall 2015125 96 units in Canada

Engine

Certain ambulance or fire package vehicles with 6.7L diesel engines may experience a "stop safety now" warning message and 5 audible chimes if an Exhaust Gas Temperature (EGT) sensor fault is detected. Engine torque would be gradually reduced by 70 percent over a period of 45 seconds to a power-reduced level that is maintained. During this time, there would be no effect on steering, braking, lighting, electrical, or restraint systems, allowing the operator to maneuver the vehicle to a safe location. Such an occurrence could also result in an engine shut down and subsequent inability to quickly restart the vehicle. If this condition were to occur when an ambulance or fire engine vehicle was transporting a patient or providing medical assistance, it could delay medical treatment and increase the risk of injury to the patient. Correction: Dealers will reprogram the Powertrain Control Module with updated software.

Recall 2013372 50 units in Canada

Engine

Certain ambulance package vehicles with 6.7L diesel engines may experience a "stop safety now" warning message and 5 audible chimes while the vehicles gradually loses power, eventually resulting in the engine stalling when speed falls below 5 km/h. If this were to occur while the ambulance is transporting a patient, engine shutdown with no ability to restart could interfere with patient care and increase the risk of injury to the patient. Correction: Dealers will replace the exhaust gas temperature (EGT) sensor located downstream of the diesel particulate filter (DPF).
