2019 Ford F-150: adaptive cruise control problems

Filed Jul 2, 2026 · Transmission · FL

I have had multiple incidents with the transmission. The first incident happened when I hap cruise control activated and was doing approx 65mph. It was not raining. Suddenly my transmission dropped from 10th gear to 4th gear. I was able to stop the vehicle without incident. The other problem is when accelerating it will shudder continuously until you ease off of the gas pedal. It happens every time.

Over the years the engine has felt like it was slipping or stalling. It appears to be increasing more. Sometimes it happens while cruise control is on. Today, the engine slipped for a prolonged time, more than usual, and then RPMs decreased. Warning sign of a “wrench” appeared on screen and said see manual. I was also unable to put vehicle in reverse. Slips more at lower speeds when accelerating.

On [XXX] with an empty vehicle besides I myself the driver, going south bound on [XXX] just north of twin falls Idaho I had cruise control set to 81 MPH when I felt a slow to the vehicle then noticed an uncontrolled/unprompted shift and loss of power indicated on the dash cluster jumping from 10-9-7-10-5-3-8-9 gears then transmission temperature went from 176 degrees to 205 degrees for the remainder of the trip. I proceeded to pull over and let the transmission rest for 45 mins then proceeded with my trip after not seeing any exterior damage or leaks. And it did not shift higher than 9th gear while cruise control was engaged even at lower speeds. The transmission then began to experience harder shifting, and gained a shutter like a clutch pack not engaging properly form 1-3rd gear, and sporadic shifting under light normal driving conditions at random intervals and remains to now have a normal operating temp of 204 degrees under normal driving conditions. Took it to be diagnosed at a ford dealer and it was the CDF drum that lead to a a cascade of issues leading to the transmission needing replacement.

Traveling at 75 MPH with cruise control on the transmission shifted into 1st gear. I slowed down and reset the cruise control to 65MPH. A couple of minutes later the transmission again shifted into 1st gear. This happened after driving for about an hour. There is no recall on my F-150. WHY NOT? Thank you for your help.

For the last four months, February 2023, through June, July 2023 the main computer screen will intermittently go black. This illuminates the N vehicle, NAV system, phone system, backup, cameras, Ford cameras, driver, seat, control. This vehicle was covered under a warranty. This vehicle was brought to the dealer and an error code could not be generated. The dealer states that this is the sink system. Video will be attached if this complaint form allows. Despite video the dealer will not replace the sink system. This is a danger to anyone over the age of 70 driving this vehicle or perhaps any age individual. In addition, the NAV system, directional control, Forward adaptive cruise control appears not working at the same time. This is a health and safety issue perhaps even a life endangering situation.

I was driving on the freeway at about 75 MPH. I wanted to pass another car, so I pressed the accelerator petal to 100% (floored it) and took my foot off the petal immediately because I changed my mind. Roughly 1 to 2 seconds after the inputs, the engine rev'd up to about 3000 rpm, and then changed gears, jerking my truck so violently I could have lost control. I was able to get the behavior to repeat for me, and next time I'm on the freeway I'll try to record it. It's possible I was in cruise control and in eco mode. I have been having many issues with the transmission, including some 'bucking', shuddering, harsh shifts, grinding noises, rattling noises, high-pitch whine, surging revolutions, stuck in gears to name a few.

I purchased a 2019 Ford F150 2.7l Ecoboost with 10speed transmission in May 2022 and it only had 19,000 miles on it. When I first bought it, it seemed to drive fine, but less than 3000 miles later the gears started shifting really hard, especially 3rd through 5th gear. I took it to my local dealer and they reset the PCM module and said to drive it because it has an adaptive transmission that it would have to relearn driving habits. Well, shortly after I was on the interstate doing 75mph on cruise control in 10th gear, the truck shifted all the way down to 1st gear, went to limp mode, then revved rpms and went back to 8th gear then wrench came on the dash light. This truly could've been a bad situation and possible accident if I wasn't able to get over to safety lane. I took it to the dealer the next week and they reset the computer again and cleaned valve body. The vehicle still has hard shifts between 3rd and 5th gears, although not quiet as harsh. Ford needs to issue a recall on the 2019 Ford F150s with the 10r80 transmissions or figure it out soon. I'm afraid there is going to be a serious accident, if one hasn't happened already, if these transmissions are not fixed soon. Several states already have class action lawsuits about this particular transmission.

While driving on the highway today, I needed to accel quickly to avoid being in the blind spot of another truck as I was merging onto a different highway. After getting past the truck, I let off the accelerator pedal, but the vehicle continued to speed up. When this happened, I assumed that the cruise control was somehow trying to resume so I tapped the brakes to cancel it, but nothing happened. I then put on brakes, but it was simply fighting the engine as the vehicle continued to accelerate. I then tried pressing both the cancel button and the off button on my cruise control, but the vehicle continued to accelerate. By this time I was easily up to about 85 MPH and had now other choice than to put the truck in neutral. I left it in neutral for about 3 or 4 seconds and then put it back into drive and the acceleration problem was resolved. This could have been a very bad situation for an inexperienced driver. I plan on stopping at the dealer where I purchased the vehicle last year and report it to them as well.
