Recently my car has had a series lights come on including 4wd fault, pre-colliosion assist not available, service advance trac, hill start assist warning, and something with the brakes when in reverse. I took it to the dealer and they said it's something electrical that will need parts, and further investigation with removing the seats. That will be another day. Today, while driving with my son in the back, I was taking a u-turn on a busy street. The car acted like it switched into neutral (but didn't), and wouldn't accelerate, leaving me inching into traffic at 1 mph with cars going 40mph coming at me. Luckily I was not hit, but easily could have been. I drive almost 60 miles a day for work and this is a safety hazard not just for me, but my family too.

The intermediate shaft has gone bad on my 5 year old car. Noticed it on 12/11/25 after owning for 1 year. I’m slowing losing oil which then can cause my engine to go out. I have read many things stating other peoples frustration with this $3.59 part going bad in the 2021 ford explorers but to get it fixed you have to drop the entire engine resulting in it costing $1,800. I think ford should be responsible for this and aware to make a better part.

NHTSA ID 11756607 · filed Aug 12, 2026

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.

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 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.

I parked my car and when I returned to it the car would not start. Diagnosed as a faulty fuel pump. Had this problem occurred while I was driving it could have caused serious injury or death. There is an active recall on fuel pumps for the 2021 Ford Explorer that does not apply to my VIN number so Ford will do nothing to remedy the situation and parts are impossible to find as dealers scramble to fix the vehicles included in the recall.

The third-row seat headrest in my 2021 Ford Explorer is stuck in the upright position and will not fold down, preventing the seat from fully collapsing. This affects rear visibility and cargo use, which may create a safety concern while driving.

Vehicle is not even 5 years old , and passenger headlight - low beam failed. Ford Dealership quote is around $3000. Online forums show that this is a defect for the platinum models. I feel I should be protected as I am still paying for this vehicle and plan to keep it for many years. This is a major safety component as without a trusted lighting system, this vehicle can be dangerous and lacks peace of mind.

Queja por reparación defectuosa de recall en mi Ford Explorer Estimados Señores: Por medio de la presente, me dirijo a ustedes para expresar mi profunda insatisfacción con el servicio recibido en su concesionario relacionado con un problema de recall en mi Ford Explorer [indicar modelo y año del vehículo], cuya reparación, realizada bajo su supervisión, no ha sido adecuada. En los primeros meses de 2024, llevé mi vehículo a sus instalaciones debido a un recall emitido por Ford, relacionado con un sonido de media frecuencia resonante (de tono profundo) que se manifiesta al conducir a baja velocidad sobre superficies irregulares. Según se me informó, este problema fue causado por un defecto en una pieza, la cual supuestamente fue reemplazada en su momento. Sin embargo, después de meses de lidiar con el inconveniente inicial y tras un extenso tiempo de espera, el problema parecía haberse solucionado temporalmente. Desafortunadamente, en noviembre de 2024, el problema ha reaparecido exactamente con las mismas características, lo que me lleva a sospechar que no se realizó un reemplazo adecuado de la pieza defectuosa, sino únicamente un ajuste superficial. Al comunicarme nuevamente con su concesionario, se me ha informado que no pueden hacer nada más porque el supuesto reemplazo ya se realizó. Este tipo de respuesta es inaceptable, considerando que: 1.El problema persiste y claramente no fue solucionado de manera definitiva. 2.El recall original fue emitido para garantizar la seguridad y funcionalidad del vehículo, lo cual no se está cumpliendo. 3.Como cliente, esperaba un servicio honesto y de calidad, especialmente tratándose de un problema cubierto por un recall oficial. Solicito formalmente que este caso sea reabierto y revisado nuevamente, ya que mi confianza en la calidad de los servicios proporcionados se ha visto seriamente afectada. Espero que Ford y su concesionario asuman la responsabilidad correspondiente y brinden una solución definitiva al problema

Two TPMS sensors have failed on this vehicle. Although these sensors are required under the TREAD act, Ford has advised through their dealer that this is not a safety issue and the TPMS sensor batteries failing less than 3 years from date of vehicle manufacture falls in the category of normal wear and tear. Note that the vehicle has 27,243 miles on it, and these are the original TPMS sensors/wheels/tires that the vehicle came equipped with from Ford.

The front tires chewed to pieces, one blew, and the dealer initially felt it was an alignment issue from the factory. Up one further inspection, they found an aluminum toe rod with a 45 degree bend. I believe this was a factory issue as we hit nothing on the highway. It seems from an FMEA point of view, it is likely the blown tire and momentum of the car bent the tie rod and that the tire damage was caused by a part failure or some other issue with the car. It is a 3 month old car with 9,400 miles. The car struck Nothing on the highway.
