2021 Nissan Frontier

My 2021 Ford Explorer appeared to maintain or resume speed without cruise control being activated. Braking and switching cruise off did not reliably stop the behavior, and speed varied by as much as 15 mph without my input. My concerns are: * apparent speed control when cruise had never been activated; * continued propulsion after braking; * apparent cruise operation after its dashboard indicator went out; * inconsistent response from the SET/accelerate control; * fluctuations approaching 15 mph I drove the Explorer on 9/18/26 on the interstate for a few hours and cruise control was bananas. The vehicle was clearly using cruise control, even though I had not turned it on. Even after I would break, it would want to resume a speed. It had a headset its own. When I would turn on cruise control, and see the light on the dashboard indicating that it was on, I could set it at a speed, but it would not necessarily stay at that speed. Sometimes it would slow down and start coasting or sometimes just adjust the speed downward by only 4 mph. When going downhill, it would definitely accelerate. Using the set/acceleration button would sometimes work for acceleration and other times not. When I would turn the cruise control off and see the light on the dashboard had gone off it would continue to operate cruise control. I could see as much as a 15 mph fluctuation in my speed without touching brake, accelerator or button. Regarding your listed questions, the vehicle has not been inspected by anyone since the incident, there were no warnings or messages. i did not feel unsafe in the vehicle at the time. I’m hoping my husband will drive it today to see if the problem occurs again.

When someone is sitting in passenger seat the light for their airbag blinks, is on or off. So we are unsure if the airbag would in fact deploy if we were to be in a collision.
