The clock spring in the steering has failed causing the airbag to no longer work on the driver side. The cruise control turns on and shuts off on its own. Sometimes won’t even let you set it. Volume controls no longer work. Horn no longer works. Steering has a clicking catching sound now when turning. Steering controls no longer light up and none of the buttons work.

While driving 75mph with cruise control set the transmission downshifted to 3rd gear. I put it in manual to shift the gear back up to 6th gear. This is the 3rd time it has happened in 6 months the first and second time was while driving in Mississippi on I-10 East and Westbound in the same trip. The last time was Sunday April 5th 2026 at approximately 1145 AM CST while traveling on I65 South in Alabama. No lights came on the dashboard when it happened.

Problem: Engine unexpectedly goes to idle speed after accelerating up to highway speeds. Cruise control was not engaged at time of failure. This has happened three times, all after a cold start up, and all within 2 miles of home. The most recent occurrence being 6-19-25. At time of failure, multiple warning screens come up on the dash, including "Hill Start Assist Not Available", "Service Advance Trac", "See Manual" (with a picture of a wrench). No check engine light comes on, and no error codes are set. Engine does not respond to accelerator pedal, engine will only idle roughly. When this occurs, the only remedy is to pull over to the side of the road, shut off the engine, then restart the vehicle. Each time this has happened, the engine starts and runs normally with all warning messages cleared from dash. Safety Concern: Unexpected loss of power can increase the likelihood of an accident, especially in heavy traffic. This truck is used frequently for towing, and an unexpected loss of power can create a loss of trailer control. Dealer Contact: Last September when this issue initially cropped up, the truck was taken to our Ford dealer for diagnosis. They kept the truck for approximately two weeks, driving it daily without having the issue reoccur. They performed diagnostics on electronic modules but found no concrete issue. Inspection: Truck has not been inspected by the manufacturer, only the dealer. Warning Lamps and Messages: "Hill Start Assist Not Available", "Service Advance Trac", "See Manual" (with a picture of a wrench)

It's the same issue as Recall Notice 22S02/the federal safety agency Recall 22v011. The replacement part is MR3Z-7583-A 1X ($2-$5 part with 30 second install), but they do not show it under parts for my truck, they would prefer to sell me the whole brake pedal assembly ($50+ part and labor probably diagnosis charge in addition to part replacement). The part becomes brittle and breaks. This caused dead battery, 5 hours from home, due to lights staying on, allowed me to start and put truck into gear without touching the brake, lost acceleration between 45 & 50 mph, cruise control would not turn on and message presents that hill assist is not available.

Driving 68mph with cruise control engaged, truck violently jerked. Gear indicator went to 1st and started flashing. There was no gas pedal response. The truck was just coasting. About 10 seconds later, the gear indicator went back to 6th and resumed normal operations. This seems to be the same lead frame issue earlier f150s had with this transmission but no recall has been made for the 2015’s. This is a serious safety issue and needs to be addressed by Ford

When using adaptive cruise control sometimes the truck will unexpectedly brake when passing large vehicles (Semi-tractor trailers, dump trucks, delivery trucks). Has only happened when passing large commercial vehicles on the left (US style, driver side left; my passenger side/other vehicle driver side facing each other) but not passenger vehicles. Happens in both night and day, and at random (doesn’t occur all the time). Has happened multiple times since buying vehicle used in 2019.

I was driving down the road like I always do, the cruise control just shut off. I tried to re-engage it and it would not respond, about 15 minutes later I engaged the cruise control successfully. This has happened numerous times over the last three weeks and now in order to engage the cruise control, I lift with my fingertips, the top left and the bottom left of the button and then it will engage. One occasion, the dash lights in trip 1 mode flashed. Then the control began working again.

My adaptive cruise control system still malfunctions and slams on the brakes automatically because it thinks it sees a vehicle in front that I am about to collide with. This only happens when I am passing large vehicles (semis, fuel semis, etc.) to my right when driving on highways. And it does not happen all the time (maybe 10-20% of the time I pass a semi on my right). But, when it does brake it scares me and then I have to press the gas hard so the person behind me doesn't rear end me. This is part of an issue I reported previously in 2015, where my truck would slam on brakes when passing large semis and also when passing under bridges at certain times. A recall was issues for this, which took care of the braking when passing under bridges, but did not completely fix the issue when passing large vehicles. I followed up with the federal safety agency again in late 2015 and 2016 that the problem is still happening. I will upload the emails below as attachments.
