I have a 2016 Yukon Denali used, to which I bought the extended warranty, glad I did, the phone charger pad and heated front seats didn’t work.
I bought floor mats and a few other things fixed a long with having all the fluid’s changed for $2,280.
I say, go for it; if it makes it safe, it’s well worth it.
