IMO, yearly maintenance cost is an arbitrary number. Cost per mile is a much better measure. I use the Fuelly app to track fuel and maintenance costs for my 2012 Ram CTD and the wife's 2014 T&C.
According to the app my maintenance costs are
$9,301.44 for my Ram for 59,091 miles or $0.1574/mile. Owned since 2016
$1,722.86 for my T&C for 57,788 miles or $0.0298/mile. Owned since 2017
Just my $0.02
