Assuming the vehicle is fairly stock, have you had the battery checked? I know, sounds stupid but so many stupid things happen on these when the battery starts to go out. You know, things like door handle unlock sensors stop working. I'm sure it's something more serious like a BCM, PCM, something like that. Or maybe Sync3 needs an update, just being cynical, sorry. Do you have a scanner you can use to look for any codes? Can you post the messages you're receiving in FordPass?

I see the Traction control and ABS Light..... Perhaps it's a wheel sensor?

There are no codes, only alerts on Ford Pass. Battery checks out. The truck started doing this after the Battery Box was replaced due to the fire recall. Now the lights are on all the time. Can't get a service appointment till 12/9Screenshot 2022-12-01 at 8.58.22 AM.jpeg

If it's after the battery box changeout my money is on a bad ground. These vehicles are sensitive to the mV level for all of the sensors and technology. Bad ground connection will play havoc with that.

Latest. update on the warning lights staying on all the time. Dealer said it was a lose connection on a ABS sensor on one of the wheels. I'll be surprised if that the fix. Picking it up today after 3 weeks at the dealer, again. Keep you posted on the results.
