2021 Ford F-150 Hybrid

Rear Axel Bolt Failure. Please help. This has been an issue for over a year with newer F150s. Most failures occur on the "Max Trailer Tow Packages" with the "floating rear axel". You'll see multiple failures on new trucks. Mine has ~18k miles. Dealer says it's unsafe to drive. Many are finding broken bolts incidentally when getting tires rotated. Others like myself hear it rattling. Someone will get hurt. I have a rental car provided by ford because it's deemed unsafe.

The contact owns a 2021 Ford F-150. The contact stated while attempting to make a turn from a complete stop at an intersection, the accelerator pedal was depressed but the vehicle failed to respond. The contact stated that the START/STOP feature was engaged at the time of the failure. The contact turned off and restarted the vehicle several times and the vehicle responded. There was no warning light illuminated. Additionally, the contact stated while driving in a construction zone with the Lane Departure Steering Assist mode engaged, he turned the steering wheel to avoid the construction cone; however, the vehicle veered to the opposite direction and was pulling towards the construction cone. The contact also stated while driving and passing a semi-truck, the vehicle jerked and was pulling to the right, towards the rear of the semi-truck. There was no warning light illuminated. Additionally, the contact stated while driving at an undisclosed speed, the vehicle pulled toward an embankment. The contact deactivated the Lane Assist feature. The contact stated while driving and depressing the brake pedal to make a complete stop, the vehicle failed to respond. The contact stood on the brake pedal, but the vehicle hesitated to respond, causing a 10-foot stopping distance delay. The vehicle was taken to the dealer where the failure could not be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the dealer. The failure mileage was approximately 9,000.

While traveling at around 70 mph, the truck felt like it losing power. As I further step on the accelerator, the truck didn't response. The truck then jerked and shifted to gear 9 and jerk again then shifted back to gear 10. This happen for about 10 to 15 minutes and back to normal. During this time the truck loss the ability to accelerate. This happen during the cruise control engaged and also happen without the cruise control engaged. When this happen, the truck had about 35,000 miles and it happened during a road trip from Southern California to Flagstaff, AZ. The problem also happened on the way home. The problem was not observed as the truck travel at 65 mph or less.
