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.

It started moth my vehicle losing power and chugging , dealership diagnosed as transmission (10 speed ). 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 . Maybe 2 weeks later truck starts bucking as I enter the highway , was close to getting rear ended . Brought vehicle to dealership 2 weeks later diagnosed with the turbo going out in it . And then Friday 3/14 driving home from work the check engine light comes on. Says emission issues ? Also says need to service engine soon . Dealership says it is fine to drive they will call me when they can figure it out ? My vehicle ha less than 25k miles these issues started when I had 17k on it Started 8/5/24
Oil level 1/2 quart high, and smells like gasoline.? Actual mileage on truck is 8,544 last oil change @ dealership @ Wiscasset Ford on 5/6/24 in Wiscasset, Maine. 378 Bath Road 04578-9431 I was informed this is an issue. But what is the fix.?
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.
Water leaks into spark plug wells causing vehicle to lose power no cover is over the sparkplugs
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.

Brakes pedal is soft and keeps going down as you push on it. The peddle does not pump up. Ford dealer says that that’s the way Ford Ranger brakes feel. There are no warning lights and no noise coming from the brake system. Engine idle, the engine idles at 900+ rpm’s, if you don’t keep the break pedal firmly pressed the truck moves forward. I found myself in the middle of an intersection at a stop light this morning. Ford dealer says that is what Ford specifically requires that the idle be set at. I have found numerous similar complaints on the internet from Ford Ranger owners.

The engine has a squeaking noise, unknown where it is from. The noise is upon start up and while driving, I do not know if the issue will lead to engine failure. Which if the engine locks up and cause drivability failure.

After driving a 700 mile round-trip, I got home and parked my vehicle in my garage. It have a strong smell of fuel and oil mix what's your is exceedingly strong the next morning when I woke up and went into the garage. I pulled the oil dipstick out, the level was 2 inches higher than normal and it reeked of gasoline. I went to my local Ford dealer at Palmbay Florida service manager told me Ford is aware of this problem and has no idea what is causing it but they will replace some stuff on the vehicle but I'm not certain that will fix it. There are a number of Ford Ranger owners at https://www.ranger5g.com/ who have fuel in the oil issues. This issue goes back to the 2019 models.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
