Differential Unit problems of the 2017 Ford F-150

The contact owns a 2017 Ford F-150. The contact stated that while driving at various speeds, there was an abnormal sound coming from the engine compartment. The contact stated that the failure had gotten progressively worse. The vehicle was taken to the local dealer where it was diagnosed that the cam phasers and differential had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 66,000.

Vehicle makes vibration style noise from the rear right side during speeds of 40-50 mph with minimal acceleration and/or during low rpms. Vehicle was taken to 2 different dealership service shops on 4 occasions during the warranty period who all claimed it was a normal sound. Researching online during that time was pointing to potential misalignment in the rear-differential during manufacturing. Condition can be replicated during driving conditions, between speeds of 40-50mph, light application of gas pedal and during low rpms. Condition existed from time of purchase through present day.

My new F-150 front differential leaks. When trying to slow down vehicle I can hear knock sound and around front axle and sudden decelerate.

On 01-24-2019, I stopped at a red light and noticed an odor coming from my 2017 Ford F-150 truck and saw some smoke coming from under the hood. A motorist next to me pointed to the bottom of the truck; I rolled down the window and he said he thought there was a fire under the truck. I pulled over, shut off the truck, saw a small fire on the frame under the engine. The other motorist put it out with a fire extinguisher. A state police officer called the fire dept. Who further extinguished the smoldering. The vehicle was towed. My insurance company sent an adjuster who concluded that the fire was caused by a failed pinon seal in the differential, which is part of the power train. The legal department of Ford motor CO. (office of general counsel) stated that the fire occurred because the vehicle was driven on pavement in 4wd. I assert that this is not true and is a tactic of Ford motor CO. To avoid honoring their product warranty or taking responsibility for a potential safety hazard.

Tl the contact owns a 2017 Ford F-150. The contact stated that the vehicle drifted to the left and right while driving.

The dealer replaced the steering gear and the entire steering column. Also, during another visit, all four tires were replaced and three alignments were performed between dealer visits. The contact took the vehicle back to the dealer due to a rear differential failure. The contact stated that the dealer was reluctantly checking the steering again. The manufacturer was not notified. The failure mileage was 4,000.
