Drivers side rear axle bolt sheared off. Noticed noise coming from rear while driving, removed wheel, bolt head and washer fell to the ground. Bolt head and washer we-??re both retained. Local dealerships (albuquerque, NM) do not have the capacity to diagnose the truck for a minimum of two weeks. The structural integrity of the axle and drivetrain are in question.

Broken retaining bolt holding the wheel on the right rear axle. Dealer said too dangerous to drive so they replaced axle. Dealer has old axle and broken bolt. This problem exists in the 2021 F150 Powerboost truck with 9.75 in 3/4 floating axle. Several postings on F150 forum of this happening to others with same truck. Nothing holding rear wheel on except brake caliper if bolt brakes and wheel wobbles loose. When service tech takes wheel off to rotate tires the broken bolt falls on the floor.

When drive train goes into electric drive mode, the vehicle will jump/lurch/bang after stopping like I was hit by another car pretty hard. This will only happen when the engine either goes into hybrid electric mode or engine turns off after a stop in sport and other modes. It will not happen in tow mode where the engine stays on. The issue is the aux pump on the transmission going bad, this was found by dealer and part is on national backorder. Truck can jump a foot forward at red light if foot is not smashing the brake pedal down - seems to be an issue popping up daily on forums from others having issues.

Truck does not always does not always downshift to a lower gear at a stop and instead remains in 8th gear. This poses a safety risk do to a lack of acceleration and also causes an unanticipated sudden jerk when it does finally does engage in a lower gear.

Drive shaft on 21 F150 broke in half while driving on 07/01/2022. I was traveling at 35+ MPH. This could have been much worse at a higher speed. Truck has been to local dealer (Mac Haik) for service twice in last few months, they never mentioned the recall. Dealer contributed to failure by not evaluating issue for over 20,000 miles.

I took the vehicle in for a tire rotation and oil change at approximately 18,000 miles. The dealer informed me that the passenger side rear axle bolt had sheared off and that the bolt had to be drilled out and replaced. The repair did not solve the problem and now the axle has to be replaced.

I was driving down the interstate, traveling around 70MPH and my check engine light came on as well as a notification to my phone. The phone notification from the Ford Pass app read: POWERTRAIN MALFUNCTION / REDUCED POWER What is Happening": Illuminates when the system has detected a powertrain or a four-wheel drive fault. What should I do": A powertrain or all wheel drive/four wheel drive fault has been detected. Contact your authorized dealer as soon as possible. The vehicle wasn't responding to me pushing down on the accelerator, as if the engine had just stopped working. I bought this truck new in October of 2021 - it is a 2021 F-150 and currently has only 9,500 miles on the odometer. As soon as this happened, I thought back to an article I saw recently about the Ford Broncos failing.. connecting the dots, the same engine that is failing in the new Broncos, the 2nd generation 2.7L V6 is the same engine in my 2021 F-150. It has not been diagnosed as of this moment, it will be diagnosed tomorrow; however, I am afraid this case is the same as the others reporting issues with the 2nd generation Ford 2.7L V6 - I may need a new motor!

The Check Engine Light illuminated and brought to Ford dealer. Was advised it has code P237C which is a failed Exhaust Heat Exchanger, dealer ordered part # ML3Z5A212W. There is no coolant leak visible from the failed part. But driving down the highway around 70mph, the vehicle suddenly decelerates and goes into Reduced Power Mode, throttling back the engine. The reduced power mode is displayed on the instrument cluster, but it is still startling to have the vehicle decelerate, especially at highway speeds in traffic. And would be more problematic with a trailer in tow. My Ford dealer has the part on order but Ford states it is on back order with no expected delivery date. Very disappointing from a quality stand point, but a concern as well from a safety perspective. I know others have had a similar issue which is also accompanied by a coolant leak, which I do not have on my vehicle but I am concerned and continue to monitor for leaks and watch the fluid level. I do not have any photos of the valve. Unexpected reduction of engine power in my opinion is a safety issue, especially at highway speeds or when towing. Thank you for your review of this issue.
