2021 Ford Ranger engine problems

Filed Sep 28, 2026 · Engine · NM

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?

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.

Excessive fuel in the oil. Oil smells of gas and is diluted. Almost a quart high at 3000 mile mark. Dealer and Ford admit this may be an issue on some engines but it is supposed to be normal??? We installed a pcv catch can and it will fill up with fuel in about 800-1000 miles. That is almost 8 ozs. The included photo shows oil at about 4000 miles. The second hole you see in the dipstick is above the full mark.

The critical level of FUEL DILUTION (Fuel% = 5.5) in the motor oil of this vehicle's 2.3L EcoBoost engine poses a Safety Hazard due to its system's Fuel Leaks and Fire Danger probability existing since the vehicle purchase. I am concerned for the safety of everyone because this vehicle has been evaluated to be a Fire Hazard with 104.5C via ASTM D93 Closed Cup Flash Point. The Motorcraft's Safety Data Sheet (SDS) is listed as >185C. Ford Motor Company (FMC) inspected the vehicle numerous times but safety issues remain. For this reason, I took it out of service and parked at my residence until this problem would be resolved entirely in according with the law. The vehicle mustn't be driven on its power.
