2011 FORD F-350 Complaints

It’s doing the death wobble and has almost made me lose control on the interstate and seriously could have had my 9month daughter and I killed.

The contact owns a 2011 Ford F-350. The contact stated while driving 55-60 MPH, the steering column and the front-end of the vehicle started shuddering significantly. The contact depressed the brake pedal and slowed down significantly until the vehicle operated as needed. The contact was able to continue driving. The contact stated that the failure occurred a second time while driving over a bump on the roadway. Additionally, the contact stated that the failure recurred a third time while his wife was driving. The dealer was notified of the failure and informed the contact that the failure could not be duplicated. The dealer referred the contact to the manufacturer and the contact was referred to the NHTSA hotline for assistance. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 47,000.

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.

The contact owns a 2011 Ford F-350. The contact stated that while stopped at a traffic light, the accelerator pedal was depressed; however, the vehicle failed to accelerate. Additionally, the check engine warning light was illuminated. The vehicle was taken to the dealer, where the mechanic replaced the EGR cooler; however, the failure recurred. The contact linked the failure to Customer Satisfaction Program: 21M04 (Exhaust Gas Recirculation Cooler). The vehicle was taken to a secondary dealer, Heartland Ford (5979 US Hwy 136, Covington, IN 47932) however, the part to do the repair was not yet available. The manufacturer was made aware of the failure. The failure mileage was approximately 75,000.

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?

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.

at any given time traveling over speeds of 50-60 MPH truck has a wobble that can't be stopped until I slow down completely. at highway speeds this can be very dangerous.

Death Wobble in 2011 Ford 350 Super Duty double cab long bed. 1st time happened Oct 29th 2022 heading to Gail TX. Construction on road and went down a bump and it started then. 2nd time & 3rd time (Nov.2022) within a few minutes of each time, going down a road and hit bumps within a couple of miles of each other and did death wobble again. As I have a Down Syndrome daughter and a grandchild still in a back facing child seat, this death wobble is a definite safety issue in transporting them. I am currently waiting on a mechanic to look at it. Have not yet had time to take to Ford dealer in town closest to me.
