I think you missed some of the posts. There are many people that have taken their trucks to the dealer multiple times, and the problem still persists. The dealers have been unable to remedy the problem in many cases, and people have new vehicles they cannot depend on. It may not be that big of a deal for those of us without problems, but others are not so lucky.
Difficult ? Sounds like phantom draws so yeah, heck of a pickle Ford pit themselves in but then the maverick isn't the only model suffering.
Did Read post. You said you got new Michelin tires did not say they were defender 2's, assumed you were replacing the OEM Michelin Primacy made in Mexico questioned if yours was actually made in Mexico. Check date on the one you got made in Canada, I believe that defender 2 were just recently changed (don't remember exactly what new rubber compound? Seems like something else also?). It may be that the Canadian one is an older stock than the other three?
I think the sulfation is the problem. The battery sulfates from just setting around partially discharged. It gets discharged because of all the electronics that are running even when it is shut off, plus all the communication going on between the truck and Ford. After the battery gets a little sulfated, the time it takes to go into shut down mode gets shorter and shorter. You need a pulse desulfator battery minder to reverse the sulfation. Here is the one I use..........
I put in a master disconnect for my powered subwoofer and amplifier. I also have a Diehard T4 470 CCA 585CA battery now. No deep sleep issues for over a week.
Sam's club had them at $744 for 4, mounted balanced and road hazard, we travel a lot so wanted to be able to have tire shop anywhere, have two stores nearby.
There's no need for a master disconnect for your audio. Just wire a proper turn on lead, instead of using the signal sensing turn on. I believe the previous poster was implying a master disconnect from the entire truck, which I'm sure would keep the truck functioning. I only mentioned pulling fuse 11, because that is strictly related to the telematics of the truck and nothing else. I, along with many others, believe that is the single biggest contributor to the battery getting drained when the truck isn't in use.
Definitely on pulse desulfator minder. I use a noco genius 5 as I don't always put it on. It can spend 2-3 days on the slow blink optimize procedure. I am reluctant to use the 1-2 amp ones with the computer/sensors pulling what they do overnight. I intend to install the pigtail to the jump posts and hang the end out just under hood. (The noco has one with the rubber cover to keep dirt and moisture out). May even mount it in driver's door fender badge.
$744 = great. I moved from Sam's to Costco primarily due to store locations several years ago. I usually get my tires at Discount aka America's Tire/Tire Rack. As they price match and are everywhere. My Ford dealer sent me text that they will price match (and/or not sure which) free alignment with tire purchase. Since I will be buying tires before my 3yr/36k is up I will most likely buy them from him, have the works oil change and tell him to check any warranty possibilities.
. It looks like on my Michelin Primacy I will get about 30k miles (they are 45k rated). I put 35psi in them this am at 33°F so they will be pushing 40psi about 70°F.You must also turn off auto-updates since it automatically reactivates the wifi.
My '23 hybrid sat outside two days at motel. Once was -30 next day -29. Started both days. Otherwise always in garage overnite . .19,000 miles.
