2021 Ford Ranger Driver assistance Problems

The 10R80 10-speed automatic transmission and the gear-shift linkage module are defective, and the truck remains available for inspection. Our safety is constantly put at risk because the transmission exhibits an extremely violent, highly intermittent powertrain lunging jolt during deceleration and stopping. The impact is so severe that it sounds and feels like a loud gunshot firing right next to the cabin occupants. Furthermore, the transmission simultaneously exhibits severe throttle hesitation and gear-skipping. This causes the vehicle to drop gears and completely fail to move when attempting to accelerate at busy stoplights, trapping us as a sitting duck in active traffic. Earlier in our timeline, the technician improperly reassembled the shift linkage, which caused the multi-ton vehicle to refuse to engage in Park and violently roll backward down a steep residential incline; an emergency parking brake deployment was required to prevent a catastrophic accident. The transmission defect was physically confirmed by [XXX] of Papillion, who verified scored, sticking fluid control valves inside the main control unit. Additionally, the hazard was officially confirmed by BBB AUTO LINE National Arbitrator Sharon Katt (Case XXX). The arbitrator officially signed a ruling certifying that our safety, use, and value concerns are completely valid, explicitly noting that the intermittent nature of this transmission failure does not minimize the extreme safety hazard. There were no warning lamps prior to the failure. The symptoms first appeared at ~49,000 miles. The dealer has since refused advanced diagnostics, executed an irrelevant radio reset instead, and willfully fabricated a fake service record on CARFAX on April 21, 2026, to force-close system safety alerts in their database.

The Factory Driver's Side Floor Mat does not stay snapped in. This causes the Floor Mat to slide forward towards the pedals. This causes the Floor Mat to lodge underneath the accelerator pedal, which can cause an inability to accelerate. The Fllor Mat could also lodge undermeath the brake pedal, not allowing the full use of the brakes.

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.

Several warning lights, which included: ABS failure, Parking Assist Failure, Lane Avoidance Failure, Traction Control Failure, as well as having steering difficulty. ( mileage 24500 ). The problem was found by dealer to be an eletrical connector underneath the vehicle at the mid point, with their belief that it was corrosion, which I believe to be a defective component and design. I contacted Ford but they were not interested in retrevale of the connector, so as to diagnose the failure. ( I am keeping the connector )

The backup camera on my truck washes out at night when the lights are turned on and backing up, rendering it useless. The washout is not as severe with just putting in reverse without lights, but still dangerous. The local Ford dealer states this is inherent in all Rangers, Broncos and other vehicles.

Lane departure features is excessive. I've twice now had to make an emergency lane change to avoid an accident occurring in front of me and the lane keep assist almost forced me back into the lane and potentially causing me to get in an accident. I have had to turn this feature off entirely, which means I do not benefit from it in normal conditions. The only way to deactivate the lane keep assist when changing lanes is to use a turn signal. You cannot use a turn signal in emergency situations where it's either you quickly change lanes or you get in an accident at high speed on the highway. No, I'm not tailgating... the reality is this stuff happens and these "safety" solutions that take control of the steering wheel are not safe if they cannot tell there's an emergency situation happening. I cannot have the steering wheel resisting my input when I'm avoiding an accident. I need full control. This is poorly designed.
