2020 Ford Explorer: lane keeping assist jerks the wheel

Filed Sep 15, 2026 · Driver assistance, Electrical · NJ

I own a 2020 Ford Explorer XLT AWD, VIN 1FMSK8DH6LGA35229. While driving, my vehicle displayed “4WD Fault – Service Required” along with the powertrain wrench warning. I then became unable to select/change drive modes. Pre-Collision Assist became unavailable, I experienced Lane Keeping/Lane Assist problems, and additional stability/traction warnings appeared. A professional diagnostic scan found AWD codes C0631:7E-68 and C0631:7F-6C related to the front axle disconnect actuator. The ABS module also stored U0102 (Lost Communication With Transfer Case Control Module) and U0155 (Lost Communication With Instrument Panel Cluster). My mechanic diagnosed failure of the front axle disconnect actuator/intermediate-shaft system. The repair requires removal of the original disconnect system and installation of Ford’s revised intermediate shaft/axle components, replacement of the vent/breather hose, and AWD programming. I was quoted approximately $1,337. The mechanic will then determine whether the transfer case/AWD control module also requires replacement, which would cost approximately $828 additional. Ford has issued TSB 25-2373, superseding TSB 23-2174, for certain 2020-2021 Explorer AWD vehicles. The bulletin specifically identifies C0631 and/or C00A6 and the front axle disconnect actuator/intermediate shaft and directs replacement with a revised intermediate shaft. I am concerned this is a safety defect because the failure resulted in AWD/drive-mode malfunction while multiple driver-assistance systems became unavailable. I request that the federal safety agency investigate this known failure and determine whether a safety recall is warranted.

The first component that fails and gives a warning is a 4WD failure. Once this warning occurs it cascades into a failure of collision assist, a sudden loss of adaptive cruise control, traction control and lane assist component. When this first occurred and my vehicle would suddenly slow down on the highway, because the cruise control would suddenly shut down and swerve due to the lane assist also shutting down. these warnings and failures did not reset immediately when you shut the car off and would last for days at a time. this would also happen randomly either on the highway or local roads. This is a known issue to Ford and they have issued TSB 23-2174 in regards to this.

On [XXX], after starting my vehicle, I received multiple safety warnings, prompting the check engine light and a wrench icon on the dashboard. The alerts included issues with the anti-collision system, hill assist, traction control, lane departure, and adaptive cruise control, as well as my drive modes which were also unavailable. I contacted Raceway Ford in Riverside, CA, and dropped off the vehicle that day, reporting the errors. The dealership informed me the next day that the Half Shaft Speed Sensor had failed and would cost $870.52 to replace. Since the warranty had expired a month earlier on [XXX], this was no longer covered under the drivetrain warranty. I agreed to the repairs. After installing the new sensor, and conducting a test drive, additional errors appeared. After two weeks in the shop and multiple follow-ups, the dealership concluded that the AWD/FWD sensor had also failed and replaced both sensors. The repair documentation references TSB 21-2270, SSM 49045, and C0631. I believe this raises serious safety concerns and should warrant a recall, especially since other vehicles are experiencing similar issues just a month after warranty expiration.

I purchased this 2020 Ford Explorer ST, used while still under factory warranty. Within a week or two the IPMB module started malfunctioning, this affects all of the safety systems to include reverse brake assist, lane keeping assist, rear view camera and more. I have had the vehicle in two different dealerships over 9 times in the 15 months I have owned this suv, and within days of the problem being fixed the unit malfunctions again. I have tried to have the vehicle bought back by the dealer through their customer service program and the BBB of Michigan, to witch both claims have been denied claiming that the chicle does not fall under the NYS lemon law policy for used cars. The issue I have is this problem started within 1-2 weeks if purchasing the vehicle. What are the next steps that can be taken to have Ford Motor Company but this vehicle from me, as there is recall after recall on the unit in question.

The issue was initiated when you turn the vehicle on. The vehicle would process through normal startup modes, and then produce several error codes and light illuminations, all within several seconds. The illuminations would consist of; Traction Control Error, Auto Hold Error, Descent Control Error, Lane Assistance Error, and Collusion Avoidance Error. This would then maintain the error during the trip or until the vehicle was powered off for several minutes. After the power cycle, the vehicle would start and show no symptoms of any error codes, at all. This would happen in several different instances a day, lasting several months. In several of my cases, this would disable traction control for longer periods of time throughout the day or week as well. This places extreme risk to drivers who may not know that there are so little standard safety features active while behind the wheel. Additionally, it affects drivers ability to stop, which traction control and auto hold disabled, and reduces the safety of everyone else on the road. I took the vehicle twice to a Ford Certified dealer and repair shop to investigate the issue. The technician was able to verify the codes that arose from the incidents. However, the first instance when I took the vehicle in, they were unable to locate a solution to the problem. After the second visit, they recommended a complete reprogram of 5 major computer modules that have created the system error. I inquired since this seems to be an issue widespread that they could not identify as a user error, but rather an equipment defect. They indeed charged me for the service when this should be something that should be issued a recall and fixed at a wide spread level. The safety of others while on the road are effected and may lead to serious vehicle accidents as a result of the failure of the vehicle component.

Transmission shifts from reverse to park and drive to park on its own. Also, heads up display goes blank and sensors / backup camera stop working. Front collision monitors also do not work as well as lane departure sensors

This issue has happened 4-5 time in a years time. When driving with cruise control and lane assist enabled the car will pull to the left when it see's a dark line in the road. If i were not holding on to the steering wheel I would have been in the lane next to me. I think what's going on is lane keep or lane assist thinks there is a curve in the road and tries to correct for it. Its just a matter of time before a crash happens to a Explorer owner. I have been to the dealership 3 time for this and called Ford but they don't seem to care.
