Rear differential/axle bolt broke, destroying other parts and making vehicle unsafe at the moment and then inoperable. Vehicle had previously had the recall work done for this exact issue prior to any issues/damage. Dealership is repairing the vehicle under warranty, but made sure to tell us that this is a known issue and the only true way to “fix” the issue is to install an aftermarket brace (at our cost).

When given gas to move from a complete stop, vehicle lost all power. After vehicle lost all power to rear wheels, warning lights flashed on cluster. Manually moved vehicle to side of road and checked under SUV to see rear axle was at a unusual angle and later discovered rear axle bolt on road. Vehicle was towed to dealership, which originally completed recall repair in July of this year, for this known issue. Repairs have been completed after 2 weeks, and was informed by dealership it was roughly 6 thousand in damages.

We received notification from Ford that there is a "rear axle bolt fracture" possible on our 2021 Ford Explorer and noted we were to contact our dealer to address. However when I reached out to the dealership (and then subsequently to Ford Customer Service) I was told that the issue was being treated on an "extended warranty" basis. We would recognize the issue when we noticed severe vibration and lost of mobility in the vehicle and that putting it in Park would not keep the vehicle from rolling. Based on those calls, my wife could be left on the side of the road, involved in a fatal accident (to her or others) etc., instead of addressing the issue as a preventive measure. In addition, nothing in our coversations or in their notice involved the cost to us for additional damage to the vehicle, towing or a rental car (as the dealership said they wouldn't even be able to order the bolts until the fracture occurred and they had the vehicle in their shop. The service code for this defect is 24N01. As of this date we have not experianced this issue but am trying to avoid it occurring since it is a known defect by Ford.

The contact owns a 2021 Ford Explorer. The contact stated that while reversing, there was an abnormal clunking sound coming from the rear differential, with the vehicle vibrating. The vehicle was taken to the dealer and was diagnosed and determined that the drive axle, wheel hub assembly, and the hub splines needed to be replaced. The dealer informed the contact that the vehicle was previously included in NHTSA Campaign Number: 22V255000 (Power Train); and was repaired by Hutchinson Ford of Forsyth (288 Harold G. Clark Parkway, Forsyth, GA 31029). The vehicle was not yet repaired for the recent failure. The manufacturer was not informed of the failure. The failure mileage was approximately 113,000.

This vehicle has an electronic shifting transmission and when shifting from drive to reverse, the system lags significantly (1-3) seconds before engaging reverse. This has been an issue causing several close calls. In addition to not being able to back up efficiently and being left hanging in limbo while waiting for the transmission to engage, the vehicle also continues to roll forward causing near collisions. Happens while maneuvering the vehicle in situations where a three point turn is necessary or when trying to quickly go from drive to reverse in an attempt to avoid another traffic unit or on coming hazard. Has been brought to Ford for them to check and they advised after a test drive that the vehicle shifts smoothly. The smoothness of the shifting was not the concern. It was the lag between drive to reverse. I believe it needs a software reprogram for the transmission.

Hard shifting

Jan 2025

There was no lights on the dash but the transmission was shifting very hard when slowing down. I took it to the dealer for service, but the dealer says the transmission is full of debris and needs a full replacement. When slowing down it was causing the vehicle to buck forward very hard advancing it forward and causing me the driver to feel forward force from the harsh bucking of the transmission.

My vehicle, a 2021 Ford Explorer ST, still hasn't had NHTSA Safety Recall 23V675 repaired. Even though the parts for the repair have been available to the Dealer for almost a year or more, they can't do the repair because they don't have the special tools required for the repair. The Ford Motor Corporation hasn't provided the Dealership with the tools. I've checked other Ford Dealerships in my area and they too say that they don't have the tools needed to do the repair and they can't get them from Ford Motors. I've called Ford Motors to complain and they tell me it's the Dealerships problem as the parts are available to the Dealerships. I've asked to speak to management but they won't let me. So, over a year has gone by and still no tools have been sent to my Dealership, Chuck Stevens Ford in Bay Minette, Alabama.

While driving on the freeway, the customer experienced a power train failure, which resulted in the vehicle stopping. Though the vehicle was able to continue driving, it would unpredictably jump gears and eventually became immobile. The "service engine" wrench light first appeared on [XXX], signaling the issue. The vehicle was inspected by Curt Service in Oak Park, Michigan, and no additional codes were identified beyond the service engine wrench light. The power train system is available for inspection upon request. This situation posed a safety risk to the driver and others on the road, as the vehicle's sudden stop and gear issues could have led to an accident.
