Power train

60 reports2 crashes1 fire
“I am reporting a potential drivetrain safety defect involving the rear driveshaft bearing on my 2021 Ford Ranger FX4 Lariat. On September 3, 2025, I brought my truck to Larry H. Miller Ford Lakewood after experiencing an intermittent abnormal whistling/mechanical noise while driving. The vehicle had 38,275 miles and was still under warranty. Ford retained it until September 6 but could not reproduce or diagnose the noise. This is documented on service invoice #415969. The noise continued and progressively worsened, eventually accompanied by increased vibration. In early July 2026, an independent repair shop identified a rear driveshaft problem and recommended replacement. I returned to Ford on July 15, 2026, where the rear driveshaft bearing issue was subsequently confirmed. Dealership personnel, including the service technician and service department director, advised that the vehicle was unsafe for my intended highway use. I am concerned that continued operation, particularly at highway speeds, could result in further drivetrain deterioration, loss of propulsion, or other dangerous consequences affecting myself and other motorists. Despite the original…”

Service brakes

14 reports
“During low speed driving, mainly stop and go traffic the truck will randomly lunge forward when the brake pedal is engaged. It happens when accelerating and the truck will shift in to second gear, then if you apply the brake the truck will act like it is going to stall, the engine rpm will spike and the truck will launch forward. If you dont force the brake pedal to the floor, the truck will continue to accelerate, potentially slamming into another vehicle. This has happened multiple times, the dealer has rebuilt the transmission and that fixed the issue for the last 6-8k miles. the issue has returned and the truck is back at the dealership for diagnostics. This is becoming a serious safety concern and the potential that someone gets hurt grows every day. I have seen other complaints on the internet about this same issue in trucks with the same transmission.”

Engine

13 reports
“Vehicle is just out of warranty and has less than 45,000 miles yet I'm being told I need a full transmission replacement. I know of 4 other rangers that as soon as they hit 40,000 or there about, began having jerky transmission issues. I reached out to ford for a goodwill request and am being told that I have to pay to have the transmission disassembled just to see IF they will pay for anything to be fixed. Is this not planned obsolesence?”

Vehicle speed control

8 reports2 crashes
“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…”

Electrical system

8 reports3 crashes1 fire
“Wiring for back up camera failed and short circuited - will attempt to retain the components for inspection needs. Safety concern - when wire short circuited, it burned the wire at the control module in the dash board, causing the control module to also fail - according the the ford service advisor at my dealership. Issue was diagnosed and inspected by Titus Will Ford service center at 11503 Pacific Hwy SW, Lakewood, WA 98499 - phone # (253) 753-1253. No warning lamps/messages/symptoms.”

Structure

7 reports1 crash
“The chrome coating on both interior door handles is peeling. The chrome coating creates very sharp edges and has already cut a passenger who was getting out of the car. I checked the internet and found that the same thing has been happening to Ford Expeditions of these same years. They have been recalled for the chrome peeling and possibly cutting passengers.”
