C0631 fault code: what 11 Ford owners reported

Front axle disconnect actuator on my 2020 Ford Explorer 2.3L AWD is failing. The vehicle stores DTC C0631-7E (Actuator Stuck On) and previously stored C0631-7F (Actuator Stuck Off). When the fault is active, the wrench light comes on and the following safety systems are disabled: AdvanceTrac, Pre-Collision Assist, and Hill Start Assist. Ford has issued TSB 25-2373 / 25-2568 for this exact issue requiring replacement of the intermediate shaft with revised part N1MZ-3A329-A and AWD module reprogramming, but there is no recall. Owners must pay for the repair. The problem is intermittent and has been confirmed with a scan tool. This is a known design defect, not normal wear, and it affects…

Several sensors starting going off all at once, car would lose power, if I tried to reverse it wasn’t able to get in gear for 5-10 seconds. It was around 78k miles. Of course my warranty ended at 75k. It was happening randomly then became more frequent. I took it to the dealer they said they think it is “dtc C0631 present referred tsb 25-2373 need to replace frontIntermediate Shaft Assembly . cost to replace is $1400.00 . then retest after.”. I was shocked to find that this was a known issue for years before it happened to me. I do not understand how this is not classified as a safety issue, or at the very least a manufacturer defect.

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…

Illuminated powertrain malfunction (wrench) indicator with DTCs C00A6 and C0631, caused by failure of the front axle disconnect actuator/intermediate shaft on an AWD 2020 Explorer at 46,821 miles. The vehicle displayed the wrench light along with "Service AdvanceTrac," "4WD Fault," "Hill Start Assist Not Available," and "Pre-Collision Assist Not Available." Multiple driver-assistance and stability systems disabled themselves simultaneously, including AdvanceTrac stability control and pre-collision braking. Loss of stability control and automatic emergency braking without warning is a safety concern, particularly at highway speed. The fault was intermittent at first. The dealer had the…

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…

We bought this our ST in April and just our luck it has passed the 5-year mark.....no powertrain warranty for us, darn. On Wednesday, during the 30-minute drive home from work, my spouse reported a fault indicator on the dash related to 4WD or AWD being inoperable. This did not trigger the MIL, but diagnostics showed DTC C0631, identified in TSB 23-2114/2174. After a costly fix replacing the FADA with an intermediary shaft, the SUV will no longer be an "Intelligent 4WD" vehicle—seems like creative and false advertising masking a known engineering failure identified by many on the internet [XXX] ). The first sign is a FADA leak. The TSB states that customers can continue to drive, so I took…
