I know of 2 other people with near exact issues on a ford and a Lincoln. There is also a pending master cylinder recall that ford said the didn’t have parts for and still haven’t heard back from them on that. Please investigate this dangerous situation.

2017 F150 Super Crew 4x4 brought into dealership for brake master cylinder recall. ( no lights on dash) Dealership changed both the master cylinder and brake booster at no charge. The same day the vehicle was picked up, I returned it to the dealership. The vehicle was having issues with keeping straight on the highway and when I slowed down when coming to a full stop, the steering wheel turned completely to 1 side on its own. These symptoms were not present when vehicle was initially dropped off. Dealership is now telling me that the ABS module is bad and that I need to pay for that repair. The local Ford dealership submitted documentation (Special Service Support Center Assistance Request) to Ford to cover related damage, but request was denied. I called Ford corporate to re-open case and appeal decision. Ford corporate would not re-open. I requested a field service engineer to review my situation, Ford said No. I asked for good will assistance, Ford said no. I asked if Ford could do anything to assist, Ford said no. It has now been over 45 days without my vehicle. The steering wheel rotating on its own after braking is a critical safety concern. The local dealership has changed the recall to complete and left me with a vehicle that is not safe to use. They claim the ABS module is bad and I have to pay out of pocket, but they have yet to provide any documentation or reports including any OBD2 codes that indicates this is not as a result of the recall work performed. In summary, I left my vehicle at dealership for recall on master cylinder and after repairs the vehicle is having issues with related components that were not present before dropping off. All I ask is that Ford can assist by covering the needed parts and labor to get my vehicle back on the road performing safely.

On 4 occasions, my F150 has went in reverse when transmission was in the drive position. The truck would travel backwards 3 to 5 feet before shutting off. The first time happened at a stop sign. Nearly backed into another vehicle. PCM was reprogrammed. 2nd time occurred on leaving my driveway. Ford replaced an ABS module. 3rd time happened in front of my house. Ford found bent pin on PCM. 4th time occurred at waste facility after unloading trash. Vehicle went in reverse when transmission was in drive. Vehicle went backwards at least 3 feet. Nearly backed into a ford F250 and pinned driver of vehicle between the 2 trucks. Ford has changed a relay. I have contacted Ford by chat, phone, and email. The case manager refuses to communicate with me about this matter.

This first began when we went to Oregon from dry Central Valley in California and hit rain. Multiple error messages appeared: Service Advance Trac, Check 4x4, Hill Assist Not Available, ABS, Steering Assist Fault, etc. Power steering assist was lost and is now intermittent which creates a dangerous situation. The ABS brakes made load groaning noises. I went to O’Reilley’s and used their OBD2 scanner. It showed codes: U1012-00, U0212-00, U0121-00, P062C-00, all being communication errors. I got a new battery and had a shop scan it. The clockspring was bad so it was replaced with an OEM from Sunrise Ford. He can’t get any communication with any of the other modules. I researched the issues and disconnected the battery while I cleaned the ABS controller connection with electrical contact cleaner. I checked some of the grounding points that weren’t checked by the shop. All of the error messages are now gone except the STEERING ASSIST FAULT. My research showed that this may be related to a wheel speed sensor or the front hub that contains the sensor. It also might be the ABS controller. I entered Engineering Test Mode and have the following continuous DTCs: C40182, C12100, C41582, C42082, C15100, C21200, C42982, C10200. Since they all end in 00 or 82 I think they are likely related. I was told in an online forum that they are communication errors. I think that might apply to the 00 errors, but don’t know about the 82 errors. The truck has under 28,000 miles and the extended warranty expired in May 2024.

Upon starting my vehicle on 2/1/20, hill assist warning, parking aid warning, ABS icon, airbag icon, and traction control icon all lit up. Called 2 dealerships on 2/3 and was told it was safe to drive. On 2/6/20, the passenger airbag deployed while driving, no impact, with my 11 year old in the passenger seat.

Went to grocery store and everything was fine. Came out of store and started truck and had no power steering. Along with error messages on display reading: service advantrac, hill assist fault, powersteering assist fault, also have ABS light on and cruise control quit working. Steering is very hard to turn and makes truck very unpleasant to drive.

. Last sunday I got a 2017 f150 xlt stuck in a small two foot snow drift. Once I got stuck I tried rocking the truck, but the transmission would not shift from forward to rear ward without the truck coming to a complete stop. After several attempts I got a fault warning for the limited slip diff. The warning for the power steering, the ABS, the parking brake, the hill descent, hill start assist, park assist warning (which I do not have), advanced track warning (which I do not have) and 4x4 low. Additionally the truck would shift in and out of 4 high, but not 4 low. In 4 high no tires would move. In two high only the left rear tire would spin. Because of darkness and grizzly bear I had to wait until morning to walk out far enough to get cell reception. The temp never got below 34 degrees, but it did rain and snow all night. When the tow truck pulled me out of the drift (a total of 10 feet) everything except the power steering worked. It was not until the 3 rd day when the power steering suddenly started to work. The dealer will not see me until next week and I am afraid I will loose all the fault codes by then. Its great to have a 4x4 that only works on dry ground. Had this happened in the winter or further away from cell phone coverage it could have proven to be a life threatening situation

Sudden loss brakes in a hard stop. There are videos explaining the problem where the ABS unit goes into bypass and for one wheel; but then the value does not reset. This issue has happened to me 4 times while driving the car, and to my wife once. Taking out the ABS fuse, and thereby disabling the function solves the problem, as the bypass valve will not engage. However you lose the mandated feature of ABS. Detailed explanation found at https://www.youtube.com/watch?v=0r46_unyyk8. This started at 7,500 miles and continued until I disabled the feature when ford could not isolate and fix the issue.

I was shocked at the number of f150's on the web with brake pedals suddenly going to the floor during all types of stopping situations. The problem seems to span 2016-17 models regardless of engine. It started yesterday with a freeway off-ramp failure and put me in the middle of a relatively safe intersection today... No brakes. I've seen master cylinders replaced to dealers stating that is the normal operation. That last part is pretty lame... Brake pedal going to the floor? The brake initially seems to work and then the pedal sinks slowly to the floor with no braking force at that point. At a full stop in park, I can repeat the failure. Touch the brake and it appears to be ok. Quickly touch it again and it immediately sinks to the floor. Apparently knowledgeable dealer indicated that there may be an ABS solenoid sticking cycling brake fluid back to the reservoir instead of being applied to brake pressure. This sounded much more logical than replacing the master cylinder unless the ABS is integrated into it in some manner.
