I had to put 3 sets of tires on my car by 50,000 miles. The Ford company told me to go to an alignment specialist because without putting some sort of aftermarket part on my car they can't properly align it and they are tired of fooling with it. I had taken my car for a regular 25,000 mile service, and my tires were so bad that the Ford company would not allow me to leave without rotating the tires. They told me that new tires are soft and not good quality really, they are for selling the car so they are soft rubber. They also told me i had to drive fast because its a muscle car and it would squatt upon going fast making the tires contact the road more even. After getting new, more premium tires and driving another 25,000 miles and the same thing happened at my 50,000 mile service, I started investigating and other year models have this same problem (years 15-23). I am in a situation where I have to put aftermarket parts on my car and potentially void my warranties and pay out of my own pocket. I have had an alignment 4 times and they say it is within specs but at the same time they say I do not have any camber adjustment left to prevent this problem. Ford makes an adjustable cam plate that is 410$ and another 480$ labor plus tax is almost a thousand dollars. Plus another realignment. This is not fair for a new car. I had to research myself and it was most definitely a safety concern. If I hadn't went right on time, I could have had a blow out. My tires have been properly rotated, and not driven in some bad way. It is also an environmental problem because I am throwing away perfectly good tires that are worn thru on the insides

NHTSA ODI 11616555

After owning the car for 3 years and putting a little under 50K miles on the vehicle, I have had to change my tires twice now because the inner tread would go bald after 20k miles or so. I had to alignment checked and the dealership said it was within spec. I have kept up with the tire rotations as well and the suspension and shocks are working as well. I believe the problem is that the camber/toe in and toe out specs are too wide that it allows for the tires to wear unevenly.

The front brakes grab suddenly during low speed braking under about 6 mph causing the car to jerk to a stop. The front brakes will lock up when coming to a stop at higher speeds at about 25 mph if the car is downshifting gears. The low speed issue happens for about 80 percent of the stops and the higher speed braking issue is hit or miss. There are no warning lights indicated on the dash. I took the car into the dealership with about 3000 miles on it. The dealership said they could not duplicate, it was just how abs works and that I needed to drive more miles and it would go away. I put the pick up date for my car as the incident date but as this is a current and ongoing issue it is every date.

1st dealer visit: at low speeds car acted like it was in neutral and then surged when trying to accelerate. Dealer said they corrected the issue. they did not. 2nd dealer visit: car was still doing the same as number 1. While on the highway with cruise control set at 75 mph, I lost power and smoke started billowing from under the car. transmission was shifting erratically, went into limp mode and i made it off the highway to call a tow truck. Dealer said they repaired the issue. 3rd dealer visit: car is still doing the same as number 1. now the car is also very jerky in 3, 5, 8 gears. I almost ran into my own car while parking due to the random lunging. It hesitates and stumbles in most gears and I have no confidence when pulling out onto a street or trying to pass on the highway. It shifts extremely hard from 4th to 5th gear; feels like I ran over something or got rear ended. The dealer wants to repeat the same repair they tried in visit #2, new valve body. -Transmission failed. dealership says valve body but the new one is broken also. waiting on the 3rd one for this car. Possibly available for inspection; it is at dealership. -Random lurching at low speeds and power loss on the highway are my safety concerns. -Dealer found the issue and attempted repair. -Manufacturer, police or insurance have not inspected. I have a ticket open with Ford currently. -Warning lamps? not on the 1st visit. yes, when I lost power on the highway but the light came on well after the issue was apparent with smoke behind me. 3rd visit, no warning lamps.
