Gen 3 raptor won’t start

[zboilla]

2000 miles on the 3rd battery, dealer just continues to replace battery. Truck was built August 29th. Has anyone else seen this problem?

That sucks, sorry OP. It's clearly not the battery. You would think the dealership would realize that after the 2nd one died! There is a draw somewhere in the electrical system that they need to track down.

No but I noticed it took forever for all my lights to go off maybe you are having the same issue

Welcome to the place, please post a pic of your Raptor. How long have you had your Raptor?

Anything aftermarket on the truck? It definitely has an excessive battery draw, they need to isolate the cause instead of just replacing batteries.

Nothing aftermarket. Just picked it up on the 8th. Have no clue. Did report with Ford so maybe they can look into it a little better.

I know mine lights up if I go in the garage with my key. Possibility that the key is close to the truck and making it light up?

3 batteries so far. I agree they should be able to isolate it. Some of the early 2021 f150 had phantom battery drain and I’m starting to think it’s trickling over to these. Have gotten 2 reports from the truck saying it’s gone into deep sleep mode.

It looks like some 2021 F150s had this problem and required a software update.

“A population of vehicles built before we began shipping to dealers require a software update to prevent batteries from losing their charge,” Ford spokesman Said Deep told the Detroit Free Press.

That’s exactly what I showed the dealer. They say that it doesn’t fit within the build date range so there is no way that could be the problem.
