(Cause Discovered - Mice/Squirrel Chewed Rear Axle Wire Harness) 4800 Miles and Multiple Fault Alerts Have Gone Nuts!

[The Weatherman]

After nearly 5000mi of flawless service, my Lariat Lux Eco 2.0 has just gone el’crappo-de-cluck-cluck.

It had been parked for a couple of days when my wife went to go to town. I got the following alerts in my phone:

However, this morning when I started it again, I got at least seven different alerts on the dash. None of those went to my FordPass thou.

I will call my dealer this morning after the service department opens at 7:30.

What makes this worse is that Carvana is due to pickup our second vehicle tomorrow in preparation for the purchase of our second Maverick in a week or two.

I have been a real fan and supporter of this vehicle and can’t say how disappointed I am to see this happen.


UPDATE:

Mice or squirrels have chewed the wire harness in the rear axle.

My good friend and local mechanic has discovered and fixed it for me this morning.

Better invest in a good preventative (spray on or electronic repellent device).

I feel for you in this situation and hope it is nothing too serious. Anxiously watching to see what the resolution is.

Considering the various system alarms, seems like it maybe electrical related. Any varmints or rodents near by? Wire harness damage? Parked outside or garaged?

Bummer. Might be a rodent/varmint as previously said they love chewing on stuff.

The 360 although cool safety stuff, worried me. Anytime some tech is added it’s one more thing to malfunction.

In what I call the boat shed. I installed a deterrent device under the hood some time ago thou. It is wired directly to the battery.

I suspect the computer is going to have to be flashed (reset). The alerts are all over the place so not likely a real single component failure.

Can’t get in to service until Friday.

Might be right on. I think I saw all those flash by.

Keep us updated. I hope it’s a simple fix!

If you have something directly wired to the truck's battery your issue could possibly be a battery low-voltage problem.

Did you try to start and drive the truck to allow the battery to be recharged?

good luck..

I turned the unit off yesterday after my wife got back home. My thinking was the battery should have been fully charged after the 20 mile trip home.

I waited until this morning to start the truck again hoping things might be normal again. Unfortunately, that did happen.

I was thinking about disconnecting the battery entirely for awhile and seeing if reconnecting it might clear the faults.

Thoughts?

Go for it. It cannot hurt since it is already bonkers. It sounds like the Body Control Module is bad or at least needing reset. I had a 2016 Ford Focus ST that would start doing things like that and I took it to Ford and they unhooked the battery and waited 5 minutes reconnected and it was fine for about a year. Then it did it again, so I did what they had done and it worked fine for about 4 plus years as I traded it in on my Maverick.

Going through Carvana and paying those prices...yikes

I believe we have found the problem!!

I put rodent protection all over the engine compartment, but they chewed thru three wires in the main harness at the back axle.

Shoutout to home town mechanic for knowing exactly what to look for.

Glad you found it - damn soy based crap.

For awareness, it's not only a Ford problem, it has been an industry problem since ~2000.

OP, what animals did that?

Glad you found it..

Good luck...

This is what we get for making the wires out of rodent food.
