very rare for your run of the mill dealership brands to offer loaners these days.
we own three different brands, Chevrolet, Ram and Honda
All three have been in for overnight warranty work over the past couple of years and when the topic of a loaner comes up, it was like pulling teeth. Last loaner I was able to get was when my DEF pump went out on my out of warranty 3500, dealer had three loaners in April 2020 and I lucked into one for a week
lot of dealers sold off their loaner fleet when used prices skyrocketed up and most haven't stocked back up. largest GMC dealer in our region changed their policy of only offering loaners if you bought from them
maybe loaners are just scarce in our area
