2021 Ford F-150 Hybrid: adaptive cruise control problems

Filed Aug 2, 2026 · Driver assistance, Transmission · NH

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

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.

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.

While driving in reverse, the rear cross-traffic alert would sometimes malfunction and not alert the driver that a vehicle or an object or pedestrian was near the rear of the vehicle.

I had my vehicle on cruise control set at 76mph I switched lanes to pass another vehicle and while still on cruise control I sped my truck to approx. 80mph to pass and after doing that my truck kept accelerating on its own. It reached a speed of 90mph during this time I was pushing on the brakes which did slow the truck but as soon as I would let go it would accelerate back up. After about 15 - 20 seconds it finally stopped doing it and the truck worked fine afterwards. I tried to reproduce the action but it did not do it again.
