Both the driver and passenger mirrors will not fully adjust. The mirrors need a different adjustment for standard driving and when towing a travel trailer. Neither mirror will properly adjust for towing and non towing applications. The lack of proper mirror adjustment causes a safety issue as the driver cannot see things in their full scope due to the mirror misalignment. I have almost had two accidents due to the mirrors not being able to be properly adjusted. Ford is aware of this issue on 2017 to 2023 F150, F250 and F350 trucks with the tow mirrors. Ford has issued a Special Service Message#51829. Ford has a cleaning procedure they wish to be done as part of the diagnostics but Ford and the Ford Dealer will not release this information. Ford is attempting to block warranty claims related to this issue. I believe they are doing this so they will not have to issue yet another recall! I spoke with a Ford Dealer this morning and they stated that they had no knowledge of the SSM51829 or the mirror cleaning procedure. Even though the truck is under the Ford warranty, they would require a $250.00 dollar fee just to inspect the problem.

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.

Door latch sensor on rear passenger has failed. Says door is ajar when door is latched correctly. 300 miles out of warranty and they would not cover it.

I have tried multiple times to get AutoNaton Ford in Union City Georgia to rectify these issues. They have claimed they don't have an autobody shop to complete the required repairs. At one point, they had my vehicle for almost 2 weeks and they still did not complete the repairs.

Head light housing retains moisture on the inside of the lens both headlights on truck. May be causing shortage of the wires

While driving, rear window spontaneously exploded. Entire glass broke out of frame. Not while hitting bump or any other unusual concussions made to vehicle. No rear defroster on. Car has under 5,000 miles. We had for over 2 years, only used rarely.

When towing a trailer, the Trailer brakes stop working. the brakes, using the pedal and lights all work perfectly on truck and trailer. But if you squeeze the brake control paddles, you immediately get a trailer disconnected message and although all lights still work, the brake controller does NOT. Then sometimes, just driving and perhaps stopping at a gas station, the trailer brakes also stop working and you don't realize until going down a hill. This has happened multiple times. I start out just fine and then ?

6/25/22 around 5:30PM, my 2021 F250 7.3 gas engine with 10k miles experienced sudden unintended acceleration. At McDonald’s pickup window foot firmly on brake pedal, my truck felt like it was being pushed away from window. Truck got up to speed of approx. 5 mph and moved forward around 30 feet, shifted truck out of drive and RPMs when up to 5k. Foot was on brake pedal the entire time. Turned truck off and walked around truck to confirm no damage, problem has not yet happened again.

Tailgate realize button in cab also on remote works while vehicle is in motion. While reaching to adjust my pedals while towing on the highway at approximately 70mph tailgate button was pressed, allowing my payload to full all over the Highway. This could easy result in injury or death to others traveling on the Highway. Also, in certain states including Florida, children are aloud to ride in beds of pickup trucks.

Speed Control: During night driving on 11/25/2021 at 65 mpg on I-80, I released my foot from the accelerator to slowdown, BUT the F-250 failed to slow down. Upon applying the brakes, the truck slowed (a message on the dash stated I applied the brakes), BUT, upon releasing the brakes, the truck ACCELERATED. I repeated the braking solution, until I found a safe pullover. I shut the truck off & put the headlights to off from auto. Problem did not repeat, but the Blind Spot, Cross Traffic, & Airbag Faults continued as long as I had the headlights on. On 11/26/2021, I left a message with All American Ford, Paramus, NJ, Service Drive Manager. This was a VERY DANGEROUS DRIVING SITUATION!. NOTE: On 10/26/2021 the 2021 F-250 began displaying errors, as logged on FORD App Display Center; “Blind Spot Detection with Cross Traffic” (Control mod comm prob), followed by “Restraints Indicator Lamp Warning” (Fault with Pass Airbag Deactivation Indicator) – This is DANGEROUS, because it INDICATED that the PASSENGER SIDE AIR BAG is OFF!! Since 10/26/2021, besides the faults, the AC would just shut off, front driver & passenger side windows would not roll down/up, Automatic high beams Failed, AC temp & radio controls were inoperable. Automatic deployment of running boards Failed. Hand touch locking & unlocking Failed, thus the push button tailgate release FAILED. I took the F-250 to Tomball Ford, TX for repair. They noticed that the right rear upper portion of the taillight was cracked. Stated this was probably the issue, given the Blind Spot Indicator Module was located within the taillight assembly. I paid $1,000+ to replace, then left for NJ & the faults & other issues continued. I deduced through trial & error, that the faults & issues ONLY occurred when the HEADLIGHTS were on!
