2021 Ford Ranger

While driving from [XXX] to [XXX] on XXX my 2021 Ford Ranger's dash light came on and I noticed harsh shifting and the vehicle began jolting unpredictably while I was driving at highway speeds. To avoid imminent danger, I pulled off the 101 and slowly drove to the closest Ford dealership, Vista Ford Lincoln of [XXX], in order to have the truck assessed. Technicians performed a diagnostic evaluation and retrieved DTC P0766 (shift solenoid "D" performance/stuck off) and P2703 (transmission friction element "D" apply time.) These codes are the documented engineering signature of internal CDF clutch drum bushing migration- a known, widespread manufacturing defect inherent to Ford's 10R80 transmission platform. Vista Ford confirmed the transmission required a complete replacement, but assured me that I could slowly drive the truck home to [XXX] for the repair. [XXX] of [XXX] confirmed the error codes and quoted me $9,857.86 to repair the existing transmission and $13,295.84 to replace the transmission. I reached out to Ford Corporate (case number: [XXX]) who explicitly refused a reasonable goodwill remedy, offering only a 10% discount against [XXX]'s replacement quote. This left me with an untenable $11, 966.26 bill for a known factory defect, therefore I transferred the truck to B'N'C Mobile Auto Repair where the transmission replacement cost me $7, 954.73 Although the 5 year express powertrain warranty concluded on XXX, a major vehicle powertrain components failing at just 48,820 miles under normal during conditions is dangerous and unacceptable. I have preserved all diagnostic sheets, including trouble codes, paid receipts and my original 2021 sale contract.

The contact owns a 2021 Ford Ranger. The contact stated that while driving at an undisclosed speed and shifting gear, the transmission shifted hard. The vehicle was taken to an independent mechanic and was diagnosed with transmission failure. The vehicle was repaired. The dealer was contacted and informed the contact that the transmission was operating as designed. The manufacturer was made aware of the failure and stated that there was no recalls on the VIN associated with the failure. The failure mileage was approximately 59,000.

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.

I've had many issue's with this vehicle's transmission: Harsh and erratic shifting. Shuddering when accelerating. Slippage. On several occasions not able to go in reverse. Issue's started at 45k miles. Had it in the shop on several occasions to address problem. I've had to replace faulty transmission at 70k miles. This is a faulty transmission due to incompetent CDF Clutch drum. This is NOT a safe vehicle to operate.

The contact owns a 2021 Ford Ranger. The contact stated that while driving at various speeds, the transmission was slipping in and out of gear. There was no warning light illuminated. After approximately 3 seconds, the transmission shifted into the correct gear. The failure had occurred while driving through an intersection, placing the contact at risk of being rear-ended. The dealer was contacted, and it was confirmed that the VIN was not under recall. The manufacturer was not informed of the failure. The failure mileage was approximately 93,000. The VIN was not available.

Vehicle: 2021 Ford Ranger. Mileage: 44,000 My 2021 Ford Ranger begin experiencing dangerous transmission shifting issues with absolutely no warning signs or indicator lights prior to the incidents. On multiple occasions the truck suddenly and randomly stalled in the middle of the freeway and in the middle of the road, feeling as if the transmission went into neutral with no power to move the vehicle. These incidents occurred multiple times putting myself and my small child at serious risk of injury or death. At no point did any warning lights illuminate or any indication appeared on the dashboard to alert me of a problem before these dangerous events occurred. The truck was taken to a Ford dealership where it was diagnosed with an electrical fault in the transmission solenoids. The final diagnosis is a full Transmission R&I and overhaul at only 44,000 miles. This issue is covered under Ford TSB 21-2315 which acknowledges that the 10-speed automatic transmission may exhibit harsh engagement, delayed shifts, and shifting problems due to known defects. My 5yr/60,000-mile powertrain warranty expired 3 months ago by time only. I am well under the mileage limit at 44,000 miles. Ford has agreed to cover only $2,097.06 of the $5,242.65 repair, leaving me responsible for $3,145.59 for a known manufacturing defect. When I contacted Ford requesting full goodwill warranty coverage, I received poor customer service a manger (Luis) promised to call back multiple times with additional coverage options and never did. A full transmission overhaul at 44,000 miles is not consistent normal wear and tear and is clearly the result of a manufacturing defect that Ford has already acknowledged through TSB 21-2315. The sudden and unexpected nature of these failures with no warning, combined with the serious safety risk posed to myself and my child, makes this matter extremely urgent. I am requesting NHTSA investigate this matter and Ford's handling of this known defect.

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.
