2021 Ford Ranger: engine stalls while driving

Filed Jun 16, 2026 · Transmission · ID

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 the federal safety agency 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.

My truck loses power at a stop, starting to accelerate is stalls in the middle of the road. It seems to be stuck in gear or not going in gear. It will finally start going and the hesitation starts a the rpm gage goes up to about 3000 rpm’s and then goes back down to 1500. This is extremely dangerous to lose power in the middle of the road. This needs to be addressed.
