I am reporting a safety concern involving a delayed transmission gear engagement and delayed rearview camera activation. Intermittently, when shifting the vehicle from Park into Reverse or Drive, there is a noticeable delay before the transmission actually engages the selected gear. During this delay, the rearview camera also fails to activate immediately. Because there is no immediate indication that the requested gear has engaged, I have experienced situations where I believed the vehicle was in Reverse or Drive, but it remained in the previous state for several seconds. In some instances, the transmission engages unexpectedly after the delay, causing the vehicle to move in a direction different from what I anticipated. For example, after selecting Reverse, the vehicle may hesitate before moving, or after changing between Reverse and Drive, the delayed engagement can result in the vehicle moving in the previously engaged direction before finally shifting into the selected gear. This creates a significant safety hazard, particularly when parking, backing out of driveways, or maneuvering in areas with pedestrians or other vehicles. The delayed rearview camera activation further increases the risk because it prevents the driver from immediately seeing behind the vehicle while attempting to reverse. The issue occurs intermittently and without warning, making it difficult to predict. I am concerned that this condition could lead to a crash, property damage, or injury if the vehicle moves unexpectedly due to the delayed gear engagement. I request that NHTSA investigate this issue to determine whether it is related to a transmission, electronic shift control, or software defect affecting the safe operation of the vehicle.

The vehicle has been failing shifting. There is something from with failure to shift. The vehicle won’t accelerate, and slows down in the middle of traffic and the truck has no other problem. I’ve only have it for 3 years with no problems. But this is a big safety issue while driving

The contact owns a 2021 Ford Explorer. The contact stated that while driving at approximately 35 MPH down a hill, the engine and powertrain were resistant when the brakes were applied. No warning lights illuminated. A mobile mechanic was sent by a local dealer to inspect the vehicle. The mechanic determined that the failure was due to the transfer case but was not related to NHTSA Campaign Number: 26V402000 (Power Train). After test driving the vehicle, the mobile mechanic determined that the vehicle was unsafe to drive. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the local dealer. The failure mileage was approximately 89,200.

Was driving down the interstate and the vehicle started making an awful noise and dash lights went crazy with cannot shift to park error on dash. We pulled over asap and shifted to park and went to exit vehicle and the car tried to roll off and wouldn’t engage in park and has since done this same thing 2 more times. Ford says there’s a recall and the software and parts won’t be available until may of 2027 I do not think this vehicle is safe to drive

I had my car parked in a driveway that has a slight incline. I was buckling my child in their car seat in the back when the car started to roll backwards. The car had been parked prior and was off when the rolling occurred. Now my car is in for service requiring an entirely new transmission (under 80,000 miles) after un-smooth driving led me to bring it in.

While driving at highway speeds, the vehicle displays a "Drive Train Malfunction" warning message and the traction control warning light illuminates. Shortly after the warning appears, the vehicle loses power and may enter a reduced-power mode or stall, creating a serious safety hazard in traffic. This has occurred while traveling on the highway, forcing sudden deceleration and creating the risk of being struck by other vehicles. The check engine light is illuminated, and diagnostic code P0A1E is present. The problem is intermittent and unpredictable, making it difficult to determine when the next failure will occur. The vehicle has been taken to Ford for diagnosis multiple times, and significant money has been spent attempting to repair the issue. Despite these efforts, the root cause has not been identified and the problem continues to occur. This defect affects the drivetrain system and impacts the safe operation of the vehicle. The sudden loss of power on the highway places the driver, passengers, and surrounding motorists at risk. Based on discussions with other owners, this appears to be a common issue affecting Ford Explorer Police Interceptor Utility vehicles and warrants investigation by NHTSA.

For full details please refer to complaint 11715221. Since the initial complaint, repairs have been completed and I will attach a list of parts that were replaced. The repair confirmed the rear axle bolt sheared and there were significant metal shavings in the rear differential. When the bolt broke, numerous other components were damaged as detailed in the repair documentation. Ford has refused to accept any responsibility for this repair even though the safety implications for this type of incident are alarming.

On [XXX], we sent a 2021 Ford Interceptor to J.C. Lewis Ford located at 309 W. Oglethorpe Hwy, Hinesville, Georgia 31313 for a recall under 23S55. The recall is a safety issue related to a rear axle bolt and the possibility the bolt can fracture. We had the recall done and returned the vehicle to service. On or about [XXX], our fleet manager was called to the Liberty County Jail because this vehicle was making a loud noise from the rear end. Our fleet manager had the vehicle towed to the county shop where it was inspected. They concluded the vehicle would need to be towed to Ford for repair since the rear axle bolt fractured, the exact issue that was addressed under the recall. A few days later, we were notified that the dealer was refusing to pay for the repair since they had already done the recall. I contacted Ford Customer Service, case number [XXX], to try and resolve the issue. After going back and forth, I received notification on February 3, 2026, that financial assistance has been denied and that this concern is caused by how the vehicle was / is used over and form of manufacturer defect or previously completed recall. The vehicle is a police interceptor purchased for use as a patrol vehicle for the Liberty County Sheriff's Office located in Hinesville, Georgia. The vehicle is assigned to our civil division and the operator serves evictions and civil documents. The vehicle is not used for patrol but even if it had been, that's the intended purpose of the vehicle when purchased. I have photos of the bolt which show it fractured and also shows the head of the bolt appears to have some damage, possibly from the manner in which it was installed. This failure has been identified as a safety issue related to the 2021 Ford Interceptor and is not a new issue. The recall referenced an axle bolt that can fracture, and that did happen but Ford doesn't want to take responsibility.

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).

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.

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 explorer has a 10 speed transmission, and its REALLY heavy on shifting like it is missing shifts or slipping, it will shoot up in rpms to the 7-8k mark and jerk forward, this will happen every few minutes when varying speed, driving through residential areas or normal trafficways not including the highway, however on the highway it has a tendency to feel as if it loses power and regains it, dropping rpms and shooting back up to 4-5k rpm, and dropping back down to around 2k. today i had the incident where the car jerked hard after a shift, gave me prompts on the dash about seeing the manual, and that drive modes are not available. this has happened in the past month before multiple times, however this time i lost all power to acceleration going down the road, ended up just coasting to a stop on a road that speed limit is 55 mph. this made me panic, because i could have possibly been rear ended, or in any other case could have been hit if my car would not have properly been able to accelerate. the car has had similar problems reported from previous owners and they have been taken into a dealership for repairs of which did not fix the problem or the problem is reoccurring. there are no warning lamps prior to the jerkiness of shifting and loss of acceleration because of it. it will jerk a handful of times and eventually give me the "see manual" prompt after the initial problem was noticed, i decided to look online for answers as to what was wrong and it seems like this is a reoccurring problem with vehicles similar to mine. Hopefully it hasnt caused and injuries, but it definitely has the possibility to from what i have experienced.
