NHTSA investigations into the 2011 Ford F-350

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.

RQ14005 Opened 13 Jan 2015 Closed 15 Mar 2016 ELECTRICAL SYSTEM:SOFTWARE

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...

Recalls on the 2011 Ford F-350

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).

STEERING

While traveling down the highway at the speed limit, the truck hit a bump and started to shake violently. I slowed down and pulled over to resecure a freezer that was shook loose. We continued on and when I went to make the next right turn, one of the straps, which was sliced during the death wobble, snapped. The freezer slid and seesawed over a cooler. The corner of the freezer came through the rear window striking my wife in the arm and head. I have brought the truck to multiple shops, replaced steering stabilizer, shock, and tires to no avail.

Within a span of 30 min. I experienced 3 uncontrollable steering oscillations also known as the "death wobble." The DW experienced, the speeds were around 50 miles per hour. Less than that, the aforementioned oscillations were not experienced. Reason for the 30 min time frame was due to making it back home from the first occurrence. First oscillation was on smooth road, the other two were on less than smooth roads.

STEERING

I own a 2011 Ford F-350 Lariat Dually truck and was driving down the highway at approximately 60 mph, when I hit a bump in the road and all of a sudden my truck started to shake violently. I didn't know what happened as this was the first time this has ever happened. I thought something happened with the rear wheels on my truck. I was shaken up, scared and had to stop on the side of a busy road to see what it was. I looked around the truck and didn't see anything and was unaware of the famous "Death Wobble" that are notorious on F-250 & F-350 Ford trucks. I then returned to the highway with my flashers on and drive, but at a lot slower speed because I was unsure of what caused the shake. I was able to make it home safely and I told my husband about it. He wanted to see if it would happen to him so he took it for a spin and it happened to him 3 times in a 5 mile trip. Therefore he came home and parked the truck. We took it to Ford and they advised that this issue is common. Having a vehicle with this unwanted feature is a concern as we purchased this truck to run a business and now it just sits. Please put yourself in others shoes. Imagine you are traveling 70 mph down the interstate with a loaded trailer and you hit a bump or change lanes and the death wobble starts to happen. Would the driver be able to prevent a horrific accident from happening or cause one by trying to slow to an acceptable speed and sometimes completely stopping just to get the uncontrollable shaking to stop. This could cause a very bad outcome for the driver and possibly other unsuspecting drivers that are unaware of the issue / situation. This is not the situation any driver wants to be in on any highway. Please consider doing a recall on all Ford F-350's trucks so that this issue can be corrected and give owners peace of mind. Imagine if your family was traveling and this happened. I ask you, how would you handle this situation?

EQUIPMENT:RECREATIONAL VEHICLE/TRAILER

Annual inspection of the Progress Manufacturing Equal-I-Zer (model number 90-02-1200) steel head assembly revealed cracks in the welds holding the two steel plates that support the spring bar sockets and the welds that attach the head component (part with the hitch ball) to the U-shaped bracket that attaches/bolts the head to the shank that is inserted into the receiver. I have pictures of the cracked welds. The assembly has been sent to a certified welding/fabrication shop for repair at my expense. If the welds failed, two scenarios are very likely: 1. The spring bars will separate from the head assembly, releasing two 20+ pound steel rods in an uncontrolled and unconstrained manner onto the pavement. Of the tow vehicle, trailer, or another car are struck by one or both rods, the result could be severe damage and/or injury. 2. If the welds holding the head assembly containing the hitch ball to the U-shaped bracket that is bolted to the shank failed, the entire hitch assembly and trailer would detach from the tow vehicle; the safety chains would provide the only mechanism to keep the trailer from detaching completely from the tow vehicle. Severe damage could occur to the trailer and tow vehicle. If the safety chains fail, the trailer would careen uncontrolled into other drivers on the road. A master welder and certified weld inspector looked at the pictures of the cracked welds and stated that "Lack of weld metal fusion, likely it was there when you bought it." I posted the pictures of my cracked welds on three FaceBook groups focused on RVing with approximately 300,000 members. Several members stated they, too, found cracks in their welds. The manufacturer was sent the pictures. They refused to stand behind their product and told me to buy a replacement head for $275.00. There were no warning lamps, messages or other symptoms of the problem prior to the failure. There may be a systemic welding problem at the PM factory.
