New 2012 Ford F250, Super Duty, 4X4, crew cab truck, purchased 11/2013. Approx. 1 month prior, the truck began having a vibration at highway speeds (75% highway driving, 25% city). The vibration got worse over the course of a day. The 2nd day the front passenger tire exhibited a large bulge (tread separation) on the inside two tread grooves. Ford replaced the tire, with another of the same brand and model. On 6/30/2014, the front driver tire, with no warning, developed the same issue, a large bulge in the inside tread grooves. The tires are Continental Contitrac LT275/65R18 123/120S tires, dot# A3B9 479B 2511. Both tires had very little tire wear and the wear was even across the tire surface, the tires showed no sign of potential failure. I did get to see the inside of the second failed tire, there did not appear to be any damage except the cord separation which was not visible from either the inside or outside of the tire; I did take photos. I contacted Ford's corporate number and awaiting a call from the dealer's service manager, and regional service manager in reference to this safety concern. Ford did state they would contact NHTSA; Ford reference number cas04645143-Z4T8T9. Each time I have to replace the Continental tire under warranty Ford has to locate the tire and it is not easy to locate. In addition, every new Ford F250 on the dealers lot has another name brand tire, which I believe indicates Ford has issue with the Continental tires. I searched the NHTSA data base and found almost the exact same incident; NHTSA id# 10568111. I also found numerous similar complaints about the tire model. I attempted to contact Continental, case #[xxx], the call taker read from a script and could offer no help.

This incident occurred on Saturday, June 14, 2014: Road conditions were dry, temperature 75 degrees. Extremely dramatic wheel wobbling. Traveling on interstate, approximately 65 mph, drove over several small bumps in the road when the shaking and wobbling started. Truck started veering into left lane of interstate. We thought our wheels were coming off due how violent this action was. Gently applied brakes, and shaking/wobbling subsided around 30 mph and pulled off of the interstate. First thing accomplished was going around and checking each tire to see if they were loose. They were secure. Have an appointment tomorrow morning, June 17, 2014 at the Ford dealership where truck was purchased. To say we were terrified is an understatement.

2012 F250 with the death wobble in the front end. Driving truck down highway at 70 mph and the front end just start to shake and feel like the front end is coming out from under the truck. Had to almost come to a complete stop before it would stop shaking. Take truck to Ford to get fixed and I'm told that it will not be cover under warranty. The two front ball joints go out and the track bar at 39K miles. They tell me that it is not cover under the power train warranty. From what I'm told Ford know this is a problem and has not fixed it yet.

I was safely operating my Ford F 250 on a concrete bridge in pine island Florida. I was traveling @ 63 mph and was making a slight left bend. The truck crossed an expansion joint and went into uncontrollable violent oscillation of suspension and steering. The oscillation was such that the steering wheel was difficult to hold on to and my first thought was multiple flat tires or a wheel came off the vehicle. Hard braking to under 30 mph was what was required to stabilize steering to "normal". that was the first time this occurred and I discussed with my service adviser at the Ford dealership that I purchased the truck from. I inspected vehicle and could see no damage of obvious problems. I monitor tire pressure regularly, have no modifications to suspension or steering on vehicle. The next time this occurred 12/26/13, I was traveling approx. 65 mph and again was in a slight left hand turn and crossed an expansion joint near birmingham Alabama on highway 65. I was surrounded by dense 65 mph traffic and the truck was uncontrollable. This time there was a near accident as I has a semi tractor trailer both close behind me and to the right side of me. Once again I had to brake rapidly to avoid crossing lanes putting my family at risk of serious accident. This is a hazardous condition and the dealer has no explanation. The force is violent enough that it could easily damage parts of the truck. As a side note, the fuel pump came apart and slung metal fragments throughout the fuel system in truck within one hour of the violent oscillation.

Violent shaking of entire truck (requiring driver to pull off highway/roads - at risk) - speed approx ~45-70mph highway/or back roads. This incident (upon research) is known and called the 'death wobble'. this issue causes a full loss of control of the vehicle. There is a known issue here (search internet on Ford 250 death wobble for video evidence - many instances) Ford must take corrective action. I now have a 2012 vehicle which is not safe to drive. Issue is ongoing and occurred on many dates many times ex. Driving approximately 5-7 miles home from groton ct to niantic ct - forced to pull off to side of highway 3 out of the 4 times the 'death wobble' ensued.

I was driving down the road and hit a small seam in the road at approx. 60 mph after hitting the small seam my whole truck began shaking violently to a point where I had no control over the vehicle. Once this happened I began reducing speed and as the speed was reduced the shaking was reduced as well. I had to come to a complete stop in order to stop the shaking. Once stopped the truck drove fine for a week then did it again and since has done it in the two week following. The dealership looked at it and said they could see nothing wrong and that everything was tight.

The contact owns a 2012 Ford F-250sd. The contact stated that while driving various speeds over a road bump or pothole, the vehicle would travel out of lane without warning. The vehicle was inspected by two different dealers who were unable to locate a problem with the shocks. The vehicle was taken to an independent mechanic for a third opinion and they replaced four shocks. The authorized dealer reimbursed the owner for the defective shocks. The manufacturer was notified of the defect. The approximate failure mileage was 3,000.

While driving 60 mph, truck hit irregularities in the road. Vehicle started shaking violently and lost control of the steering. Vehicle had to be slowed to 10-15 mph before the shaking stopped. No accident or injury occurred on this incident. Truck was taken to dealer and track bar assy / bushing was replaced. The second serious incident was @ 48,000 miles a mere 11,000 miles later. While traveling 55-60 mph through a left hand curve and crossing another irregularity in the road (bridge-pavement joint) the truck again began shaking violently and caused the vehicle to go into the oncoming lane of traffic where a log truck was traveling. The log truck was able to get on the shoulder of the road in time to prevent an accident. Again the truck had to be slowed to almost a complete stop before the shaking stopped. Truck was taken to dealer again and the only thing replaced was the track bar bushing. This vehicle is not safe!

Traveling on bumpy roads at 55 to 60 mph the front end will start to shake so violently that in order to maintain control I had to brake and pull to the side of the road. This happened several times in a day and I took the truck into a Ford dealer in Minnesota. This dealership put a dampener on the front end and I thought it was solved. However, the problem has started again in Jan of 2013. This is a very serious shake and I feel it will cause a accident if not resolved.

In Jan. 2012 I purchased a Ford F-250 rated to tow 14,000 lbs. I traded in a Ford F-150 rated at 7,700 lbs. When I hooked my camper to my 2000 F-150 the truck did not sag or squat at all. Looking to upgrade, I spoke to several sales people at several different dealerships. I was assured that the F-250 Super Duty would by far out perform my old truck. It does not. This new F-250 squats so bad it is ridiculous. On 6-18-12 I took my truck to the dealer at which I purchased the truck and complained of this matter, only to be told there is nothing wrong with the springs. Yet, the service manager said he would send me to a third party out of state shop, to have springs made and split the cost with me, because that was cheaper than using genuine Ford springs. This is unacceptable, as I did not spend thousands of dollars on a new Ford only to have someone else fix Ford problems. I contacted Ford H.Q. and explained my situation. After being on hold for some time, the person at H.Q. explained that he had spoke to, and there was no problem with my truck. I feel strongly that my decision to buy this truck, was based largely on fraudulent statements made by both Ford sales people and Ford literature alike. I have witnesses to the statements of the sales personnel, as well as to the fact that my old truck did not sag at all. I also have pictures of new truck hooked to trailer and sagging. ## information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)
