It's no coincidence they never seem to find much wrong with your vehicle under warranty, and then miraculously find a host of things that need addressed once the warranty expires.

Ding ding ding! We have a winner!
That trans issue I wrote about, The same issue I took it in for at very low miles caused the failure 60k miles later. That issue caused another issue/symptom. Both of which I told the dealer when took it for repairs. They attempted repair ineptly twice. Once replacing the first part second replacing the part that got messed up by the first problem. And thanks to trying to scrimp on warranty work, they did 2 major repairs. 1 w trans removed and one in-frame. And then ended up replacing the whole trans.
To think 2 years and 60k miles earlier, they could have fixed it for the cost of the first repair only. But ended up with 4x the work and 5x the cost.

Got it back from the dealer and when I started the next morning the start was weaker than it's ever been. It's probably close to not starting at all. Also it's starting to do weird electronic things, like the window going down when I press it to go up and the clock keeps resetting itself to 24 HR. I change it back and the next day it resets. Based on what I've read these are clear signs the batteries are going bad. Having them load tested today at the auto parts store. It's also clear the dealership essentially did nothing. If it's the batteries, can I get them replaced under warranty without the dealership? Do I just bite the bullet and buy better batteries than the motorcraft ones? I'll have to look but I think the batts carry their own warranty but being motorcraft I assume it's through Ford.

IF it were me.. IF the bats came back as BAD after the load test, I would take that truck right over to Ford and have them load test it in front of you.. The issue will be that they will say that bats may not be covered as people can cause harm to them by leaving STUFF on at night.....BUT, It won't hurt to ask / demand....

That's my plan. They are supposed to be covered for another year and from what I am reading this isn't an uncommon problem.

So took it to the auto parts store up the street. He unhooked one of the batts so each would be isolated when testing the cranking amps. Driver's side was good and had a full 750. Passenger side wouldn't even read, just came back with a code that said "replace battery". He emailed me the results. So I call the dealership. They are happy to look at it today but they said it's not an easy process. Apparently they have to put it on a Ford specific battery machine to try and fully charge it and then test to see if it holds the charge. Said it could take up to 2 hours unless it comes back with a bad battery code quickly. The guy at the auto parts store said I may be ok getting just one battery as I may have caught it in time and the driver's side has the full 750 CA's. Not crazy about the idea but I would bet dollars to donuts that Ford won't replace the one good one.

I did ask the dealership what sort of test they did when I brought it in the other day and they kept it for 2 days. He stammered and said wasn't sure. Translation: they never tested it - or at least they never isolated them. This is why I hate dealing with dealerships. Spend all that money on a truck and can't bother to even try to diagnose an easy thing like a battery. So I have to waste more of my time and take it to get it tested somewhere else and back to the dealership again and wait til it's fixed.

Finally - the dealership replaced both batteries under warranty. The reason "upon inspection found both batteries to be leaking"

Means they never even looked at it for the 2 days they had it earlier in the week.

The Motorcraft batteries that come with the vehicle are typically pretty good, but the ones you purchase from the parts department are junk.

I've noticed that too....why is that?

The battery in my 2012 F150 work truck is original and going strong. And I got 10 years out of the batteries in both of my Ford diesels and the only reason I replaced them was because I was getting worried due to the age of them. But I have noticed the replacement Motorcraft batteries are not as good.
