2015 Ford F-150: ABS light or ABS activating

Filed Sep 4, 2026 · Airbags, Electrical · CA

This is a supplemental complaint to my earlier report regarding the federal safety agency Campaign 26V237 / Ford Safety Recall 26S28. The recall remedy (PCM software update) was performed at W.C. Sanderson Ford in Healdsburg, CA on XXX. The original downshift defect recurred within weeks, including a near-miss where I nearly lost control of the vehicle with my [XXX] son inside. Since then, I have had the vehicle independently scanned twice, including a full all-systems diagnostic scan. The scan shows a communication fault (U0401, "Invalid Data Received From PCM") present across five separate control modules: ABS, Airbag/Occupant Classification System, Power Steering Control Module, Tire Pressure Monitoring/Body Control, and the engine module. The scan's own assessment recommends repairing CAN-BUS wiring and connections. I believe this network-wide wiring fault may be the actual underlying cause of the condition recall 26S28 was intended to fix — the recall's software update assumes a signal-loss problem can be resolved in software, but if the root cause is physical wiring, the remedy would not correct it. This would explain why the defect recurred so soon after the software update was installed. A second code, P2112 (Throttle Actuator Stuck Closed), also appeared spontaneously while the vehicle was parked. This code is documented in Ford's own Technical Service Bulletin 16-0139 (issued 2018), indicating Ford had prior knowledge of related fault patterns on this vehicle range. Of particular concern, the Airbag/Occupant Classification System is affected by the same communication fault. This system governs airbag deployment behavior based on occupant detection, and my son rides in this vehicle regularly. The vehicle is currently not safe to drive. I am requesting the federal safety agency evaluate whether the 26S28 remedy adequately addresses the underlying defect, given evidence that a wiring-level fault — not solely a software issue — may be the true root cause.

the truck has been acting up for several months now. it has been throwing out strange codes when attempting to start {parking brake malfunction, oil light, power train system default, ect} and often times it WILL NOT CRANK unless we hook it up to a battery charger for just a bit of time. The truck has a new battery that was installed by autozone, where it was bought {6 months ago}. Since we were in town, we stopped by autozone to get them to attach the code reader. {power train system and ABS malfunction} while driving, later in the day, the trucks auto start/stop system turns itself on and stops the truck dead in its spot.(danger: we were pulling onto the road {fm 2100} during rush hour traffic, when the trucks system went haywire and stopped us dead in our tracks in the center of both turn lanes and two of the main lanes.) there was no restarting, nor were we able to get the gear to change into neutral in order for us to be able to move it out of the main roadway. when we were finally able to move it, we hooked a fully charged jump box {one rated for up to semi truck sized vehicles} to it to get it started, and it simply would not crank for quite a while. at this time, we took the opportunity to recheck the oil level, which was set at full. After several minutes of begging "the truck" to just start so we could just take her home, it finally cranked up and home is where we took her. the truck has 19771 original miles on it. it was drove off of the show room floor, back in 2015, with 6 miles on it, and has had absolute regular maintenance and has only had one owner.

Driving on highway at 60 MPH, climbing slight incline, multiple warnings regarding hill assist, ABS, traction control, etc. Populate on dash. Truck goes in to "limp" mode, steering becomes stiff and speed reduces until it comes to a rough idle.

I was on the highway and the hill start assist/traction control lights started coming on. A few hundred miles later, more dash lights started flashing and then all dash lights went off and the truck lost all power. I could no longer accelerate. After a moment, it started working again. After a few more miles, it did it again, and this time when it powered down, the ABS break system went on and created a terrible grinding noise and brought me to a stop on the side of the highway. I limped it on the side of the highway, trying to find an exit, and the truck repeatedly did the lights flashing/power down/breaks applied several more times at low speed. The nearest exit was about 10 miles, so I had to continue to do this for some time. Once I was at an exit, I disconnected the battery for about 20 minutes. When I re-connected the battery and started the truck, everything seemed fine, but now the check engine light was on. I decided to just risk it and keep driving, so that I could get home. About 100 miles later it started doing the same thing again. I was close enough to home to get off the highway and take back roads home. It did it a few more times and then quit doing it. This was a very dangerous situation, as my truck basically stopped while I was on the highway going 70 MPH, and could have caused a serious accident, and left me no option but to either be broken down on the side of the highway or drive at very low speeds on the shoulder. The ford dealer that I took the truck to told me that they can't replicate the issue and all diagnostics come back clean, so they are not able to fix anything. Others online that have had the same/similar issue have said that ford said that it is a damaged throttle body that needs to be replaced, but the dealership that I went to did not suggest that as the cause.

No hill assist flashed first, then traction control, then flashed check engine warning. Engine stayed on but in idle only with no throttle control, lost power steering too. Got to side of road. Pumped throttle. No response. Turned off. Restarted and cranked little longer than normal and started but idling rough. Turned off again. Restarted. Smooth that time. Dropped in gear and drove 4 hours home in sport mode at 75 MPH. No more issues last week till yesterday morning. Drove wife to dr on our 45 mile back country roads. Issue came back. This time ran rough when restarted. Then smoothed out. Did it 3 more times on way there. Which was 6 miles. On way home, reoccurred multiple times never getting it above 40 miles per hour before happening again. Called 3 tow companies, all were 2 hours out. Limped it home with flashers at 25 MPH. Had towed today to diffee ford in el reno. They said yes a tsb, but no ford not covering the cost of repair 61,340 multiple law suits have been filed complaints on the throttle body defective needing replaced leaving driver stranded.

This issue has now happened 6 times without showing a pattern. While driving the vehicle completely loses all throttle power and the message center displays 'service advancetrac' 'hill start assist disabled' and the ABS and service engine lights illuminate. This has happened on back roads at slower speeds and on highways at 70 MPH. Again, all throttle power is lost. This issue has been reported on numerous forums and there have been 2 consensus fixes, replace throttle body and an apparent issue with the tightness of a throttle cable.
