Mopar Max Care is the only warranty I would purchase. I had a lifetime one on my Durango and never any questions asked...just repaired the vehicle. I also had a Mopar Max Care on my Jaguar and again, never any questions to the Jag dealership, just paid the bills.
My wife bought an aftermarket one for her 2019 Laramie Longhorn and it was absolutely worthless(AC Evap went out and Throttle body(I replaced) and refused both). We cancelled and got what money we could from them.
I repeat, I would NEVER buy an aftermarket regardless of who sells it. I used to work for Mazda Corporate and felt bad for the customers that were sold that stuff.
