So had an interesting time...the ESS dash light came on, from posts on this site was pretty sure it's the Aux Battery. Put a meter on it, very low but decided to keep driving it for a while until I could get an appt with my dealer. Talked to the service dept. said since it's a 2020 they were surprised that the battery lasted this long...what? They then said they'd need it for at least a couple of days to run diagnostics before being able to cover it under warranty....what? (Days..? and couldn't get an appt. for a week and a half)
Problem solved, tried to start it this am, received all sorts of dash lights, was in park but the system said I was in "D"....jump got me going but decided my time was worth more than waiting on the dealer.
Picked up a replacement Platinum AGM AUX-14-1 (approx. $115). Looked at the three possible ways to replace the battery - (1) remove the fuse box and come down from top, (2) remove the Fender or (3) remove the fender liner and come up from the bottom. Didn't want to mess with anything from the top so did the "super easy" Fender Liner removal to get access.
If you're replacing the battery I'd highly recommend this method. Removed the front passenger wheel, removed the 5 fender liner bolts and approx. 7 "push-in" plugs, drilled the three edge plugs and then just slipped the liner out. (You have to drill out three of the liner plugs as they go through the liner, the rest the liner slips behind). Dropped the battery holder, replaced the battery, tested the start - all good, replaced the liner, put in new "push-in" plugs, bolts and tire. Everything working perfectly, so decided to replace the main battery with a deep cycle just to stop the madness. (A smaller H6 will fit but used an H7).
