My wife was driving and the horn started blowing and the rear wiper started ejecting all the wiper fluid. When I showed up to assist, it smelled super hot and I had to pull the fuse and negative lead to make the wiper pump and horn stop. It was towed to a Ford dealer, who found the main engine harness had MELTED going into the engine compartment fuse box. The horn and wiper fluid pump also had to be replaced. It's fortunate this did not result in a fire. Ford dealer had the vehicle for TWO MONTHS to repair (and we had to take it back for the horn and washer pump). The Ford dealer said they could not give any reason for why this happened. The entire main harness and fuse panel had to be replaced. No check engine or warning lights appeared when this happened. My wife had to pull over on the side of the road.

The transmission malfunctioned on the Interstate. The car started jumping and then would slow way down to about 33 MPH with the RPM's super high and then kick back in and speed up super fast and I would have to brake constantly. I almost hit the car in front of me at one point. A different point in the same trip the car behind me had to slam on it's brakes to stop from hitting me when the car lost power. I got off the Interstate at the very next exit and took back roads home. The transmission has been inspected by a Ford Dealership and they said it was the transmission going out. At first there were no warning lights and after it started jumping and starting. Then a few days later the engine light and power train warning lights came on.

We expirenced a transmission failure on our Ford Explorer. In short summary we where driving from the airport and the problem started arising of around 5th and 6th gear downshift it would be harsh and make the car lerch. Following this we got a fluid change and that didn’t help, after the fluid change the problem got worse and produced a check engine light and at one point we got stranded on the highway because the car lost power. So we started researching and took it to a third party shop who told us that the clutch A snap ring had failed and because of that we had to get a transmission rebuild and replacement of multiple valve body’s and clutch’s. The shop also told us this was not the first explorer that’s had seen this problem, and through online research we found we weren’t the only ones with this problem. The timeline of this was from the end of May to the end of July because of overseas travel.

I recently had my vehicle serviced for reprogramming of the AWD control module after it failed. When the dealer returned the vehicle, I expected the issue to be resolved. Instead, I immediately noticed a new check engine light with code C00A6, related to the front axle disconnect. This was concerning because the dealer had assured me there were no active codes after programming the new module. After driving with the new fault, it became clear the vehicle was operating only in rear-wheel drive. I contacted Ford and was quoted $4,030 for repairs to the front axle disconnect. Given the cost, I researched whether this issue had a recall but found none, despite widespread reports from other owners experiencing the same failure. My main frustration is that this problem stems from Ford’s design of the intermittent AWD system, which engages the front wheels only when needed to improve fuel economy. The official “fix” eliminates this design entirely—converting the vehicle into a full-time AWD system. This requires removal of the front axle disconnect shaft, installation of a standard shaft, and reprogramming to support permanent AWD. The Technical Service Bulletin (TSB 23-2174) even directs technicians to cut and discard the electrical connector for the front axle disconnect actuator, confirming that the original intermittent system is abandoned rather than repaired. This is a major concern for owners. Many of us are facing the same issue, yet Ford’s solution shifts the burden of an expensive design flaw onto customers. I strongly urge Ford to address this problem responsibly and provide coverage for affected vehicles, rather than leaving owners to pay thousands for what appears to be a widespread defect.

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.
