Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“When I accelerate after a stop my truck starts jerking when shifting thru lower gears and the check engine light flashes. To increase my speed I have to slowly press the gas until it shifts thru gears. After it shifts thru the lower gears it appears to be okay. It doesn't do it at each stop but is now happening more frequently. I don't know if it's a transmission problem or fuel pump. Current mileage is around 62000. If I'm on the highway it will sometimes start jerking while the using cruise control and I have hit the brakes and take over acceleration. …”

After all of the Ford appointed tasks to fix said problem, valves were replaced , did not work then entire transmission was replaced . After 7 times in the shop and many missed work hours .

And then Friday 3/14 driving home from work the check engine light comes on. Says emission issues ? …”

“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.”

NHTSA complaint #11606865, filed 2024-08

“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. …”
