Dead Battery

[Krfonda]

Hi all, new to the forum, but a MAV owner for 9 months. LOVE my Maverick so I hope this issue can be resolved. I have read most of the threads on the battery issue, so wanted to share my experience and will update as I know more.
8/29 running errands, shut off truck, got out and it failed to lock properly, so I thought I may have just forgot to turn it off which I've done. It was completely dead, no functionality at all. AAA came, jumped the battery and I drove home knowing it needed a morning jump to get to dealer which was closing and I didn't want to leave unattended in the lot.
8/30 AAA comes to jump battery and dropped at local dealer
8/31 Dealer calls and says it was simple, just a plug was loose, all good. I went and picked it up, drove to Target again, and same thing happened. (Maybe it was Target! lol). AAA comes again, now I've learned a lot, and had to show HIM how to jump the truck. Took it to dealer. No loaners.
9/1 Truck started auto start at dealer and i drove it 51 miles out of town to the dealership where it was purchased for further evaluation. Got loaner.

Stay tuned for updates. I sure hope Ford resolves this issue. I am gun shy now because I spend time in the mountains. If there is no cell service and I have an inactive truck, BIG problem.

I think with so many having this issue, this needs to be addressed by @Ford


UPDATE 9/7: Picking up Mav tomorrow, seems to have been a software glitch. Software now has been updated. Hope this is helpful for anyone else with a similar issue.

First thing you want to do is get a jump starter like this one so you will never be stranded:

BTW, its probably NOT the 12v battery, more likely its a faulty connector in the engine compartment.

The ones, all hybrid, that I have personally seen show 12+ volts at the battery and 3 volts or less at the 2 connectors under the hood using a volt meter.

Thanks so much for the insight. I actually just bought a NOCO portable jump starter on Amazon. Says compatible with the Maverick. I only got the 12V 1000A.
Hope enough juice should I need it, here’s hoping I won’t though.

Getting a loaner for something like this used to be pretty standard. Another "perk" provided by the dealer down the toilet.

Noco is the bomb! I bought the 2000A, no way do you need that much. The 500A is probably plenty:

Replace the 12 volt battery with an AGM battery. The Hybrid was designed for an AGM (Asorbed Gas Matt) battery. But they were sold with the regular battery? (The Hybrid charges at a higher voltage and of course the constant starting. The AGM is more robust, better able to handle). Which causes problems at the auto parts store because since its not the original?

I got mine on line, $150. H4 (physical size) is the only info you need. Also dispose of the old battery properly. Lead and acid.

Anyways since replacing mine with a AGM battery in a 2022 Maveric Hybrid. All the battery saver mode issues have disappeared. I was getting them about every 10 days. Even in warm weather.
