2023 FORD F-350 SD Electrical System Problems

Multiple electrical issues related to dashboard controls, video sensors, head unit. Controls powering down while driving, sensors throwing multiple error messages. All since 1,500 miles. Ford could not figure out what the issue was so they replaced the wiring harness. After 2 months in the shop I got my vehicle back. 2 weeks later I am getting the same error messages in the dash and has to go back into the shop for the same reason.

The audio system “glitched” and all of the speakers started screeching at maximum volume. I was unable to get this to stop outside of turning the vehicle off. It is so loud my ear were ringing for hours. This is loud enough it could definitely cause someone to wreck and impairs driving ability. I could also smell the electrical in the speakers getting hot and was fearful of an electrical fire. No warning lights. Not reproducible.

My dash and head unit intermittently powers down then reboots both while I am parked and driving. It also gives a message saying it may not start up or something about low power mode, front camera error and pro assist error. I purchased my vehicle in Mar 2024 and it started around 3K miles. I've reached out to several dealerships about getting it repaired since it's under warranty and they can't even diagnose it without keeping my vehicles for days with no guarantee of any timelines. Since it need my vehicle for work and none of them will provide loners or rentals haven't been able to get the problem remedied. For some reason they need to hold on to my vehicle for days until they can even diagnose it and I can't make an appointment just to drop it off when there is a bay open. I reached out to Ford directly to see if I can get them to cover a rental car and they refused. I also asked if I can take it outside of the Ford service network because I can get it serviced faster and they said no since it is standard warranty. So I'm held hostage forced to use their service when they can't provide service timely. I have more pictures and videos as evidence.

I frequently receive messages on the dash that the the truck: Vehicle may not start/restart service now, Pre-Collision assist not available and front camera fault. My truck has died on me which in drive and reverse. My dash and console has powered down while on the freeway then restarted about a minute later. I get these messages but Ford service is too backed up to address the issue within a reasonable amount of time and they will not let me get it serviced outside of their dealer network.

Ac compressor died bad clutch internally and they can’t fix it or tell when it will be fixed anytime soon. I have been told ford isn’t making new replacements at this time. So where does that leave me?

Air conditioning compressor clutch quit working. Was told ford is t making them and was given zero information if or when it might be resolved.

I've gotten about 15 to 20 on-screen messages that tell me my vehicle may not restart, my dash just dies in the middle of driving, my car will shut off by itself One started, My air conditioning will shut off automatically, I've got an issue with craftsmanship on my rear driver side door, and a plastic molding part just fell off my truck. I have taken pictures or videos as evidence where I could when it was safe to do so. It started in April but started documenting it in May after several repeat issues. I have more photos and video but can't upload them here due to size limitations.

I intermittently lose trailer brakes when towing my trailers on my 2023 Ford F350. I have two trailers and both trailers give me intermittent faults saying "trailer disconnected' or "trailer turn signal lights not working", but the trailer is connected and the lights are working - but the brakes do not. I know this is a truck issue because both trailers have no issues with my 2017 Toyota Tundra. I have independently tested this theory with both trucks and trailers multiple times but only have the issue on the Ford truck. It seems to either be a bad 7-pin connector that randomly faults, or something with the trailer brake controller. It is very scary as I do not want to lose brakes when towing. I bought this truck specifically for towing my trailers. I have taken the issue to Auburn Ford, here in Auburn California and they tested the truck and found no issues. But my hunch is they are only using a 7-pin simulator, not an actual trailer.

I started my truck normally when a very loud screeching/ pounding was coming from the speakers. My decibel meter was reading 128 dB. Super loud! The volume didn't matter, turning off the radio did nothing. I was on my way to the dealership and stopped half way because of the noises from the speakers. I have a recording but it does even come close to how loud it actually is. No way can I drive it like this.

The contact owns 2023 Ford F-350 SD. The contact stated that the air recirculation system disengaged intermittently when the A/C was not set to the MAX setting. The contact stated that while activating the heat in cold weather, the air recirculation system disengaged intermittently, causing outside air and a strong toxic odor to enter the cabin of the vehicle, causing the contact health concerns. The manufacturer was notified of the failure and informed the contact that the vehicle was operating as designed, and that the air recirculation system could only remain engaged while the A/C was set to the MAX setting. The vehicle was taken to the dealer, where a smoke test was performed, and the dealer informed the contact that there was no exhaust leak. The vehicle was not repaired. The failure mileage was approximately 7,500.

Mileage: 7,500

The issue I am reporting concerns the management of the climate control in the vehicle. Setting a desired driver and/or passenger temperature setting is fruitless as the temperature will swing wildly on either side randomly either rendering the output to become extremely hot or cold. The safety concern is the ongoing requirement to continually adjust the settings to manage the wild swings in temperature which has been extremely concerning (dangerous) on longer commutes, tight traffic and in trailering as I must continually take my eyes off the road to adjust. The dealership has attempted to address the concern unsuccessfully and Ford will not acknowledge the concern. I am aware of and in contact with at least 4 other owners of the exact year, model, trim, options etc. with exactly the same concern and none able to obtain resolution or acknowledgement. Again, this truck is a large truck and when trailering a 40' load all attention must be on the road not fidgeting with a/c controls. Extremely unsafe. The issue arose within one week of taking delivery of the new vehicle and has continued for 7+ months without resolution. I have videos of the events occurring and have presented those to the dealership but am also told no codes are showing up during these events. No warning lamps, messages or other symptoms occur leading up to the events. The vehicle has been into the dealership 5 times attempting to resolve but todate the issue is unresolved. Have included some of the dealership's work orders and write-ups but unable to upload videos.

While driving the trailer plug melted at the connection to the truck. I got a message that the trailer was disconnected and there were no brakes on the trailer. The plug on the truck is burned.
