2021 Ford F-150 SUPER CREW DIESEL - Ratings, Complaints and Recalls

"the contact owns a 2021 ford f-150. the contact received notification of nhtsa campaign number: 23v896000 (power train) however, the part to do the recall repair was not yet available. the contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. the manufacturer was made aware of the issue. the contact had not experienced a failure. vin tool confirms parts not available."

"10r80 transmission suddenly started showing symptoms of failure at 81,000 miles. issues were slipping, jerking, and random gear selections. safety was compromised when trying to merge (gas pedal pushed but truck didn't downshift initially, then drops to very low gear or from a dead stop would start in 10th gear and barely move), also when from a stop truck felt like it went into neutral when shifting into second almost causing rear end accidents and finally it would random leave shift into extremely low gear (1-2) when doing 20 causing a sudden breaking affect. due to the safety concerns i did get the transmission replaced and symptoms have not returned. no warning lights appeared, aamco did the inspection as well as warranty company saying the transmission should be replaced."

"while driving my truck, i attempted a merge onto interstate 80, and completely lost power. i was accelerating to merge, and when the transmission shifted the truck lost all power. this is a dangerous situation and should be addressed. i cannot believe that nothing is being done about the issue, and ford knows about this, as my local dealership is months out on transmission repairs.. it would sure be great if the agency responsible for forcing a recall would work for us.."

"passenger side rear axle retainer bolt sheared off. my vehicle was manufactured 20 days after the existing recall. repair was done under warranty but obviously should be included as part of the recall."

"when moving the shift lever from drive to reverse, and physically feeling the two detents from drive, through neutral, and into reverse, intermittently the shift lever will still indicate neural and the vehicle will stay in neutral even after two physical detents have been felt (i.e. the truck should indicate and be in reverse after two physical detents). the truck and shift lever will stay in neutral even after i remove my hand from the shift lever. the truck will only engage reverse after physically pressing the shift lever further forward within the physical reverse detent area. there were no warnings on the dash and no trouble codes present within the system. the vehicle is available for inspection, and a video is available, however it is intermittently operating in this manner. when performing a 3-point turn on a roadway, this has led me to believe that my vehicle was engaged in reverse, but it was in fact not, but in neutral. this has introduced significant delay in what would otherwise be a safe maneuver and has put me and my occupants safety at risk. the local ford dealership has updated the shift software, but it has continued to operate this same way intermittently. i have demonstrated this to the dealership service advisor and shown a video to the shop foreman, however the dealership is unwilling to replace the shifter because there is no trouble code. the vehicle has not been inspected by anyone other than the local ford dealership."

"on 11-28-2023 i took my truck in for an oil change and new tires. when the wheels were removed the passenger side rear axle bolt fell out. it had been sheared off and i don't know how long i had driven it like that. the last time the wheels were off was when i had an oil change and tire rotation at the same dealership in july 2023, they did not alert me to a problem at that time. the dealer said it was unsafe to drive and i should leave it there to await parts and service. my truck is a 2021 f-150 ecoboost with the max tow package. it has 54,520 miles on it. the dealer service department has not looked at it to determine if it is an eligible warranty repair or not at this time but it is scheduled to be inspected today. there were no warning lamps or messages given related to this problem at any time. my own research online indicates that hundreds of other 2021 and later f150 owners with the max tow package have had the same problem of axle bolts breaking. no accidents or injuries have been reported that i know of but there has been lots of inconvenience because owners are told the trucks are unsafe to drive. the dealers are saying that the axles must be changed."

"i heard a scratchy rattling sound around 35-36k miles at very low speeds. eventually narrowed it down to the passenger rear wheel area. i took off the wheel to inspect the area and the head of the axle bolt fell out. it looked to have been yielded from over torquing or something. but i was shocked! i have no idea the actual period of failure. if i hadn’t rolled my windows down for the nice weather, i probably wouldn’t have heard it. i checked and there has been no recall or anything sent to me that this is a problem. i tow a camper with the family and if the axle failed while doing so, it could of killed us. very unhappy that ford has not recalled this. there are many others on a facebook group that have had the same issue. it needs to be remedied."

"it was discovered during rotating my tires that the center bolt for my rear axle had snapped off. in talking with the dealership this has been an issue with other ford products."
