Battery Woes Compliant

Another thing to look at, where are you keeping your key fob at night? Anywhere close to the truck? If the truck can detect it slightly, it will never power down.

I would put money on your battery problems being fixed if you had the dealer start updating all the main modules. My very early 21 was fortunate to have a dealer tech early on try some software updates that led to needing a module to be replaced. I then always received OTA updates very regularly.

I’m on my original battery and have never seen the remote features disabled message before.

Updating main mods? Are we talking something more than OTA updates we get? If so ... say more...

He's talking about having all the CM's being updated by the dealer. OTA's are small and not complete updates or reflashes.

Short answer - yes BECAUSE i have aftermarket battery.

I have a gen2 and have had battery issues ever since I bought mine, but nothing serious enough that I have been willing to pay for diagnostics. Also when I brought my truck in due to a new Ford dealership-bought battery dying, they even cautioned me against getting a diagnostic because of the number of aftermarket parts on my truck (lighting, comm radio, light whip ant, air compressor, etc). It’s very frustrating. Also, I hate seeing that the battery issues have persisted into the gen3s.

Installed one of these today to constant monitor/store battery life data. See what it tells me going forward....

Great idea, let us know how that goes! I should probably get something like that too.

My ’24 Dark Horse ; a May ’24 build bought in July has had 5 or 6 OTA updates pushed, but interestingly the important one - the ABS update just got pushed last week, and it’s been out since late summer ’24 !!! I got 4 or 5 updates before this one where the purported symptoms to fix were way less important.

SO the OTA updates are about as random as is possible. I think what he’s saying is go to service and tell them, don’t ask them to check every module for updates for any possible symptom. I got a BMS update on the MDH 1 or 2 updates ago, and I’m betting that strategy is shared among many vehicles. Remember, for updates you need to assert a symptom so do your homework and say you have as many symptoms as have been alleged or documented and tell them to update every related module to most current. NOT compatible - most current. Otherwise they will just connect the dongle, read the version, find no codes and mark it compatible or current. Which isn’t accurate, it’s just lazy.
