Mine goes in tomorrow. Did they at least seem to agree that it is a known problem?

They told me that they were having this problem with some other models but not with Mach E. I brought it on Wed. Nobody called yet

May be people are just not noticing it?

 

[MetrowestZ]

Just brought mine in. Let’s see what they figure out!

Finally they gave me back my car after more then a week. The problem was the light fixtures on the tailgate. They had to seal them with silicone

I also have seen what I think are some drops in the the tail lights on the hatch after rains-My car was also built in January 2022.

Those are kindergarten problems. I don't understand why such an established car manufacturer has them at all.

Mine just looked like a few drops in the tail lights. I will ask the dealer to resolve it when I bring it in for the 10 K service.
