8 months and 7500 miles into Maverick ownership, my Lariat hybrid succumbed to the faulty harness syndrome.

No deep sleep messages, first indication was the custom dash screens changed to the default settings, and the next time it wouldn't start. Probably a loose connection before it gave up the ghost. I was able to jump start it under the hood but not at the battery with a portable jump pack and limp to the dealer.

Service advisor was super nice and helpful, squeezing me in even though they had a backlog. However, it was apparent this was the first dead Maverick hybrid they had to deal with (I had to show them the 12v studs under the hood).

Later that day I received a call to hear what I already knew: voltage at the battery was fine but still not starting. Hopefully Ford has published guidance so they don't rip apart the electrical system trying to find the problem.

It's now day two and I'm just waiting to get a call saying the wiring harness is backordered. Do we know if a crimped eyelet is a sanctioned Ford repair?

I am also more than a little concerned about additional faulty soldered connections, potentially with more adverse consequences (i.e. loss of power while driving). Has anyone encountered a bad connection other than the eyelet nearest the fuse box?

Honestly, who cares if it is a "sanctioned Ford repair" if the correct repair item is on indefinite back order? If they can't get the part and they have no honest idea when the harness will be available, any reputable repair person should make a temporary safe repair to get you back on the road until the "sanctioned" part becomes available.

The crimp end repair shown in videos is a great method to get you back up and running. I spent 30 years in the electrical industry and there are literally millions of crimp connectors on very high amperage connections in all kinds of hazardous locations that have been there for decades without fail. A solder connection like they did on the Maverick is a failure waiting to happen and should have never made it past the first level of quality testing. I personally would rather have a proper crimp connector than whatever Ford comes up with as a sanctioned repair. I know if mine fails (and it probably will) I will be crimping mine on.

It matters if the shop and tech wants to get paid. Warranty work has procedures, documentation, and approvals that must be followed.
