2021 Ford Ranger: adaptive cruise control problems

Filed Nov 6, 2025 · Driver assistance · TN

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.

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.

Harsh shifting into D, loss of power when accelerating while cold. Sometimes would start across an intersection then buck, loose power and slow down then SLAM back into gear and chirp the rear tires. Technical Service Bulletin 23-2350 was performed on 11/15/2023 which updated the trans tables and cleared some codes. This helped the issue for about a week but then truck was in again on 1/22/2024 for TSB 23-2350 a second time which replaced the CDF drum. A month later, 800 miles, 2/18/2024 truck shifted HARD while in cruise control on the turnpike in traffic and lost power. DTC P0766 check engine light came on and truck would no longer move. Transmission fluid sprayed under truck. Had to be towed to dealership. Clutch Valve D was replaced. Two months have gone by and the hard shifting into D and occasional complete loss of power still occurring. Waiting for the next check engine light to appear to take it in again. I now drive very conservatively because I don't know if it will stop moving half way across an intersection again.
