I also still have the original battery on my 21 AWD and it has never given me any problems.

Yes labor too.
I just paid $250 including labor at my Ford dealer. I was surprised the price was reasonable!

My experience is that things start not working as well with an older battery. Garage door opener, outside locks, exterior door unlock/open button, my heater stopped working.

Original 12v battery here on my Jan 2021 MME build. No known issues but just purchased a new battery from Rock Auto and will install to prevent any possible issues.

10/21 build date for a GTPE and still on the original 12v. No issues but will replace before the Michigan winter hits this year.

But to be fair, not a lot of miles, environmentally controlled garage. It hasn't had a hard battery life.

my Blazer’s 2014 battery just bit the dust (won’t hold a charge for a period of time). My T/A’s battery from 2002 still cranks that big Pontiac mill. 🤷‍♂️🐩
