Three problems related to wiring have been reported for the 2018 Ford F-250. The most recently reported issues are listed below.
Upon starting the engine, no dash displays came on. I left the engine running and opened the hood to look for wiring issues, found no damage. Went back to drivers seat and dash lights were all on along with a "service required" warning light. Shortly after, the warning light went off and the truck appears normal. ## VIN failed ## Ford f250 2018#vpic# 1 - check digit (9th position) does not calculate properly; 5 - VIN has errors in few positions; 14 - unable to provide information for all the characters in the VIN. #vpic# ##.
The ac line fitting overheated causing it to explode and arc which in turn melted the primary wiring harness for the engine. This also resulted in the wire catching fire and causing burn damage to the firewall. The vehicle was going through a car wash when the incident occurred. I have been told by my mechanic that the water from the car wash prevented further fire damage.
Between 60 to 75 mph when hitting certain bumps the steering starts violently shaking and will not stop till slow down to about 25 mph. This started at around 24k and has happened 10+ times. Also at 37k sync 3 radio no longer will come on and wiring issues cannot get trailer braking to connect to the truck. Lights work fine but always shows trailer disconnected so braking doesn't work. You can also start the truck in neutral and put it in any gear without having your foot on the brake.
