Ford F-150 Hybrid adaptive cruise problems

Filed Oct 2, 2026 · Driver assistance, Engine · SC

I have a 2026 F150 3.5L Twin-turbo ECOBOOST Hybrid King Ranch. I have experienced the following behaviors: (1) rough transitions when climbing grades; (2) rough transitions when braking hard/coming down grades; (3) 10-speed transmission - electric motor slippage during de-accerelation (especially when Adapted Cruise is activated); (4) transmission seems to have gear hunting at low speeds/stop and go; and (5) harsh shifts/unpredictable downshifting with adaptive cruise. I purchased this f150 since Ford advertised the Eco-Powerboost Hybrid/10-speed transmission was built for heavy duty hauling/towing. In my mind, heat is the silent killer of hybrid long-term reliability and longevity (I live in SC - a hot climate). In my mind, I feel this electric-gas powertrain guesses my driving habits instead of responding to my driving habits.

While driving on a controlled-access highway, BlueCruise Hands-Free was active. The Adaptive Cruise Control was set to 65 MPH and the vehicle’s recognized speed limit was 65 MPH. My foot was not on the accelerator. The vehicle unexpectedly accelerated beyond the 65 MPH set speed. The vehicle continued accelerating on its own and subsequently reached approximately 82 MPH. At approximately 82 MPH, the instrument cluster showed the cruise setting at approximately 85 MPH while the detected speed limit remained 65 MPH. I did not intentionally increase the cruise set speed to 85 MPH. The vehicle was operating in Hands-Free BlueCruise during the event. The system subsequently displayed “Keep hands on steering wheel.” I have the video documenting the instrument-cluster displays during the event. This created a serious safety hazard because the vehicle accelerated approximately 17 MPH above the posted/detected 65 MPH speed limit without intentional accelerator input or intentional increase of the cruise setting. This situation happened at least 3 more times before I completely disengaged the hand free feature due to safety concerns.

Ive noticed that the electric motor sometimes doesnt want to disengage quickly when I step on the brakes. In this incident I had to make a hard brake because someone pulled out in front of me. I had the cruise control on. When I slammed on the brakes the vehicle did not stop fast the vehicle felt as if it was still being pushed by something. Then a small jolt was felt and then the vehicle finally slowed. Had I been going faster or had the car that pulled been closer. This fault would have resulted in an incident

The vehicle lost both cruise control functions (adaptive and normal) during the drive and will only reset to normal cruise control after shutting off vehicle and restarting it. Then it will only work on normal cruise control temporarily.

This happens every time I have lane keeping assist turned on and cruise control activated. The truck will periodically pull all the way to the right of the lane, to the point that the tires are on the right line and I am looking down the center of the lane. The more I fight to keep the truck in the center of the lane, the more it pulls to the right. The only way to stop this, other than disabling lane keeping, is to let the truck wander over to the right while barely touching the steering wheel. It will eventually return to the center of the lane. The dashboard graphics show a blue circle around the truck to indicate that the truck is in the center of the lane. When too far to the edge, it will change to show you are not centered. At no time while the truck is pulling to the right does the truck indicate it is out of position. Therefore, even though I am correctly centered in the lane, both by my own observation and the truck's indication, the system still pulls the truck to the right. This appears to be a systemic issue with the system. Here is a post from 2021 where someone is complaining about the same behavior: [XXX] This is a safety issue because: 1) It is fatiguing to have the system on and have to constantly fight it to keep the truck centered in the lane. On frequent 10-hour trips, I have to turn it off because it is adding to my fatigue and workload, even though I would like the benefit of proper lane keeping. 2) I can turn off the system but then I get no driver assistance when I actually drift in the lane. 3) This is most an issue when passing a vehicle in the right lane and the truck veers towards that vehicle. Again I have to fight the truck to not steer into adjacent vehicles. The Ford dealer has diagnosed the system and found no issues or software updates.

Unintended acceleration event. Initial condition: Cruise control off. Steering wheel turned 270 degrees ccw, turning left, at a complete stop, released brake, rolling forward at less than 5mph in a confined parking garage. Continuing to turn wheel to left, my right palm accidently engaged the cruise control button on the steering wheel. Cruise control automatically set to 15mph and began to accelerate. I was able to engage the brake again in enough time to deactivate cruise control. This is not the first such incident I've had where the cruise control is accidentally engaged and begins accelerating the vehicle to 15mph. Anecdotally, they have all occurred during left turns. Seeing how it engaged today, I can now understand why I couldn't figure out why it was happening previously. Due to accessibility issues, I typically turn with a single hand while allowing my other to remain capable of grabbing to maintain control. How easily my palm brushed the cruise control unintentionally was shocking.

My truck is currently experiencing a Front Camera Fault that is resulting the pre-collision warning/assist, adaptive/normal cruise control, and lane keeping warning/assist from operating as designed. Upon dealer inspection on 7/11/24 it is noted that TSB 23-2146 was issued to correct the issue by replacing cables and ultimately the image control camera and module resulting in thousands of dollars in repair costs of a known issue by Ford.

While traveling at around 70 mph, the truck felt like it losing power. As I further step on the accelerator, the truck didn't response. The truck then jerked and shifted to gear 9 and jerk again then shifted back to gear 10. This happen for about 10 to 15 minutes and back to normal. During this time the truck loss the ability to accelerate. This happen during the cruise control engaged and also happen without the cruise control engaged. When this happen, the truck had about 35,000 miles and it happened during a road trip from Southern California to Flagstaff, AZ. The problem also happened on the way home. The problem was not observed as the truck travel at 65 mph or less.

The contact owns a 2021 Ford F-150. The contact stated while driving 65 MPH with the cruise control activated, the vehicle made a hard-left turn while attempting to merge into the left lane. The contact stated that a message to assume control of the vehicle was displayed and the navigation system independently deactivated. The contact aggressively turned the steering wheel to remain the lane he was driving in. The vehicle was taken to the dealer and a software update was performed; however, the failure persisted. The manufacturer was contacted and advised the contact to reach out to the dealer for assistance. The contact stated that a case was filed. The failure mileage was unknown.

On several occasions, the cruise control has failed to disengage when applying the brake. It does not happen every time but it is unsettling when it does happen. When it does happen, the engine and the baking system are working against each other.
