Ford Ranger adaptive cruise problems

Filed Dec 18, 2025 · Driver assistance, Electrical · WV

The ACM (Audio Control Module) failed, causing a network failure in the CAN system. This caused a condition of no speedometer reading, no automatic braking, no adaptive cruise control, no fuel gauge reading, no blind spot monitoring, no forward collision, no rear cross traffic warning. Additionally, while the turn signals worked, there was no inside audio or visual confirmation that it was functioning. Also no high beam headlight indicator and no automatic high-low beams. Cost of repair was $739.00 and the dealer had to order the part.

I’ve been noticing a delay in shit out of 1st, 3rd, 6th, and 9th gear. Sometimes it slams but most of the time not. Anyways, this morning on my way to work I passed a slow driver on 2 lane road. After I merged back into the lane, I resumed cruise control and basically lost all power to the wheels. The vehicle I passed about slammed into the back of me. I canceled cruise control to give gas and the transmission was fighting me to stay in a gear. It finally caught and I drove it the rest of the way to work with the “normal” 1,3,6,and 9 being weird. My safety and the other vehicles safety was definitely at risk. The was no warning lights that came on. I haven’t had it checked out yet because this is same day

The boot material surrounding the parking brake bunches up and does not allow the handle to properly seat. When using the cruise control, the parking brake handle will raise up on its own, due to the boot material, causing the cruise control to abruptly disengage. This causes the vehicle to mildly to moderately deaccelerate without warning. This could cause rear end collision.

This truck looses power whenever someone changes lanes in front of your car. This happens even if adaptive cruise control and emergency braking is off. When someone changes lanes in front of you, even if they are going the same speed or faster, your car loses all power for 2-3 seconds, even if you apply additional throttle input. If I am on a road trip with standard cruise control on, it will cut power dozes of times per hour. If I am in the right lane with a major exit comming up, my truck will cut power every time someone changes lanes in front of me. I have had 18 wheelers lay on their horn because they do not understand why I am slowing down when there is no reason to slow down. I cannot properly explain how dangerous this vehicle behavior is. I have brought the truck to the dealer two times and they are unable to resolve it.

Truck has issue with crank position sensor issue caused due to defective design of on 2.3l ecoboost first incident shut off at 65 mph took the dealer was told it was defective crank position sensor second time a month later same thing happens third time three or four months later happens again take the dealer this time they said that it was oil permeation on the sensor itself said it was due to leak in front timing cover of motor whereas oil had ripped onto the sensor causing it to not be triggered therefore shutting down the truck completely no limp mode just dead no power also lost all systems including adaptive cruise control, anti-lock brakes, traction control, power steering, forward radar everything!! luckily all three times that this has happened have managed to not crash or get hit in the process of malfunction.my complaint is that this is a four-wheel drive truck and if the sensor is that touchy then maybe they should have shielded it now dealers requesting $2,200 to fix problem after already paying $1500 the first time to have it fixed

On the freeway cruise control at 75 mph, truck started down shifting in to 7th gear, then back up and continued to do this several times until i reached my destination. Took it out of cruise control and still did it. It did it again about 3 days later. I took it to ford dealership, they test drove it and it wouldn't do it for them.

When I accelerate after a stop my truck starts jerking when shifting thru lower gears and the check engine light flashes. To increase my speed I have to slowly press the gas until it shifts thru gears. After it shifts thru the lower gears it appears to be okay. It doesn't do it at each stop but is now happening more frequently. I don't know if it's a transmission problem or fuel pump. Current mileage is around 62000. If I'm on the highway it will sometimes start jerking while the using cruise control and I have hit the brakes and take over acceleration. I've now parked the truck because dealer cannot get to it for 3-4 weeks.

I flew down to Anchorage Alaska this brand new 024 FORD RANGER XL on [XXX] sight unseen and no test drive from KENDALL FORD Dealership. After buying the truck I started it, engaged 4 wheel drive and slippery/ icy setting. On the way back to Fairbanks the steering was hard to turn and got progressively harder the faster I drove and the colder it became. About half way home it became exhausting to steer requiring a lot of force to turn the steering wheel that actually resisted with real force being turned. I didn’t know the lane keeping would turn on with the cruise control but it did and resisted me even more. The roads became black ice and it was freezing rain. The phone charge port lost power, the dash blanked out, there was no radio and the rear power port I had switched to lost power and my phone died. I was driving about 30 to 40 mph on the 2 lane undivided snow covered black ice covered highway. In a curve in the road where the highway maintenance snow plows had stopped plowing I believe the truck mistook the snow line for the painted line and unexpectedly and surprisingly actually turned the steering wheel towards the double solid dividing centerline and I turned back into my lane. This slight movement caused the truck to totally slide out of control and cross the double solid dividing centerline and the truck went into opposite highway oncoming lane! Luckily there was no traffic coming the other way or it could have been a horrible accident. I hit the brakes and the truck actually stopped good, and then I got back into my lane and pulled over at the first chance. My phone was dead so I had no flashlight because I flew down I carried nothing but my coat. I tried to inspect the steering but it was all dark and below zero so I continued on towards Fairbanks another hundred miles to the North. The truck also had a bunch of other problems like refusing to start that can leave a person to freeze to death quickly in the Arctic below zero temperatures.
