2021 FORD F-250 SD Complaints

Fuel leaking from above fuel filter housing located on undercarriage of truck. Fuel leak is considerable and was a sudden failure versus developing over time.

Hi. I took my 2021 f250 6,7 to the ford dealership as it was having trouble starting, and just wasn’t running great. They changed the batteries, and told me it was a NOX sensor. So I went and got my truck to fix the sensors myself; because they wanted to charge me close to 3 grand. The next day I got up, lo and behold it wouldn’t crank. I had to have it towed back to the dealership. I tested codes before I had it towed, and took a video of it not cranking. The following codes showed. P2291 PCM - Injector Ctrl Press Too Low - Engine Cranking P2209 PCM - NOx Sens Heater Sense Circ Range/Perf Bank 1 Sens 1 U029D PCM - Lost Comm With NOx Sensor A P2535 PCM - Ignition Switch On/Start Pos Circ High U300A BCM - Ignition Switch It’s been in the shop a week , they called Friday saying it was starting, and there was nothing wrong with it. So I replied with all the codes, and told them there was definitely something going on. So they checked it again Monday and it wouldn’t start. Now today (aug 5 tues.) they say it may have a vacuum leak. Although non of the codes point to vacuum leak. I have no idea what to do now.

I hit an elk at 65 mph while pulling a flatbed trailer loaded with 4000 lbs of hay. The crash warning light did not come on nor did the air bags deploy. The whole front end of the truck is badly damaged. I contacted my local Ford dealer with this information and was told by the service agent that the body shop will handle this. As my concern is how hard do you have to hit something to get the airbags to deploy. I’m concerned for my safety while driving this truck again if it can be repaired. I’m taking it to the repair shop today. I wanted to report this as Ford will be ZERO help moving forward.

ON YOUR VEHICLE, IT MAY BE POSSIBLE FOR AGED BIODIESEL DEPOSITS TO ACCUMULATE IN THE HIGH PRESSURE FUEL PUMP. THIS MAY RESULT IN EXTENDED CRANKING WITHOUT STARTING WHILE THE VEHICLE IS PARKED, OR LOSS OF MOTIVE POWER WHILE DRIVING. My vehicle has been inoperative for MONTHS due to this recall, per the manufacturer. We had no warning lights or problems prior to trying to start the vehicle and that failing. We took it to the manufacturer, and they said it was because of the recall. The recall date is Dec 20,2024 and it is now June 24, 2025. That is 6 months without a remedy. This is not being taken care of in a timely manner.

Electronic tailgate randomly opens while driving and causes significant safety issue while hauling materials. Has happened multiple times.
