Owner reports
Selected complaints filed with NHTSA by 2020 Ford Explorer owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2020 Ford Explorer. The contact stated that while driving from a complete stop and depressing the brake pedal, the vehicle made an abnormal grinding sound and accelerated unintendedly. The contact depressed the brake pedal, but the vehicle failed to respond. The contact depressed the brake pedal continuously until the vehicle stopped. There was no warning light illuminated. The contact stated that the failure recurred intermittently while driving from a complete stop. The contact stated that the failure had occurred while driving downhill, and the vehicle nearly drove into highway traffic. Additionally, the contact stated that the failure had occurred while reversing in a parking lot, nearly causing the vehicle to crash into other vehicles. …
The contact owns a 2022 Ford Explorer. The contact stated while driving 55 MPH, the vehicle started to shake abnormally. While driving, the vehicle lunged forward without the accelerator pedal being depressed. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the transmission needed to be rebuilt. The software was reprogrammed and set for the parking brake to remain engaged. The vehicle was repaired, but the failure persisted. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The approximate failure mileage was 63,000.
The contact owns a 2020 Ford Explorer. The contact stated while driving at 65 MPH with the cruise control engaged, the vehicle occasionally exceeded 85 MPH and accelerated independently. No warning light was illuminated. The vehicle was not taken to be diagnosed. The local dealer was contacted; however, the vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 72,000.
The contact owns a 2020 Ford Explorer. The contact stated that while driving 75 MPH with cruise control activated, the vehicle unintendedly decelerated while the accelerator pedal was depressed. No warning light was illuminated. The local dealer was contacted. The vehicle was not diagnosed or repaired because the VIN was not under recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 26,000.
With no previous problems, over the course of the past two days the transmission has begun to hard and delayed shift in multiple gears between 10 to 75 mph. When slowing down to go through tolls this morning, as I accelerated, there was a sudden loss of power transmission and a loud rattling sound. The engine would rev in this case. I had to coast for about 150 ft before I regained control of my speed. Once I was slowing down to take my exit to get to work and wait at the light, when I attempted to accelerate to go through the light, I experienced another loss of power. However, this time the engine would not rev. Once in the intersection I was moving slowly. Had this happened (loss of power) while I was in the intersection or through the toll and someone was behind me accelerating, I could have been rear ended and injured. …
Since purchase as a preowned vehicle, we noted this vehicle is equipped with a faulty transmission/tcm software design that is dangerously unpredictable and creates erratic driving conditions. This passenger SUV Is equipped with a 10 speed automatic that (once at operating temperature) the gear shifts and operation become highly unpredictable, often causing severe safety issues navigating in traffic, slowing down to sudden stops, and any acceleration, frequently getting stuck in 1st gear or neutral while attempting to accelerate on roadways from a stop. The (10r60E) has nearly caused several accidents severe accidents while under normal use as our primary family vehicle. The Ford dealerships I contacted were aware the problem was concurrent on every vehicle equipped with that Transmission and deemed it normal operation. …
When stopped at a light the engine suddenly accelerated forcing a hard braking action to prevent an accident. after 2-3 seconds it went to idle still in gear. This has happened 3 times the third time 2 witnesses said that it was not caused by braking with their foot on the accelerator. In reviewing the three episodes I noted that the air-conditioned switch was engaged all three times when this uncommand occurred. This never occurred when the car was moving only at a stop. It seems that the air conditioner was called to turn on by the body control module which cause the engine RPM to decrease which cause the power train control module to react increasing the demand to the throttle body which either stuck high or was over commanded in not reacting in a fast enough manner to satisfy the power train control module. When this occured I thought we were going to hit the car in front of us. …
The accelerator pedal is mounted to the floor and the pedal itself is attached to the base with a very thin piece of plastic that over time separates. In my vehicle the pedal has separated and is moving freely which makes the accelerator pedal raise up while your foot is on the brakes and when you go to accelerate the pedal is blocking your foot from returning to the accelerator. The answer to question #1, the accelerator pedal and yes it is available for inspection. #2 I was nearly struck while crossing over a divided highway because my foot was obstructed by the accelerator pedal. #3 I have contacted the dealer and they advised I had to replace the part because it was not under recall. #4 I am law enforcement and I have encountered and inspected the pedal and deem it to be dangerous. …
While vehicle was driving in motion, all system error messages began to sequence on the dashboard (Steering Assist Fault Service Required, Check Park Aid, See Manual, Service AdvanceTrac, Front Camera Fault Service Required, Full Accessory Power Active, Park Brake Fault Service Now, Pre-Collision Assist Not Available, Navigation Fault). Vehicle lost acceleration and had decreased steering and braking capability. This happened on 5/20/2024 and was "repaired" by dealership then happened again on 6/21/2024. It also happened in 08/17/2021 and was repaired by dealership until most recent reoccurrences. This DOES NOT include the instances where the same error messages sequenced prevented the vehicle from even starting (for hours) leaving the motorist stranded. This is also not the first time this concern has been submitted to the NHTSA.
On March 14, 2021, a failure with the vehicle posed a serious safety hazard when my two children, another minor child and our dog were accompanying me, with the car fully loaded for spring break, and the brake system completely failed, among other electrical issues, as we were departing our neighborhood. The vehicle was subsequently towed to the dealership. I cringe to imagine what would have ensued if this defect would have occurred only a few minutes later, as we pulled into traffic or made it to the highway for our trip. I don't recall what lamps came on as it was very scary at the time, but the alerts on the Ford App were, Antilock Brake Fault, Hill Start Assist Warning, Hill Descent Control Fault Warning and Pre-Collision Assist Not Available.
