Does Chrysler still use caliper pistons in new vehicles made from Phenolic instead of metal?

I am seriously considering buying a 2022 Grand Cherokee but I question the reliability for long trips.

Burned into my memory is swapping a rear caliper out on my old Grand Cherokee behind an out of state Advance Auto Parts store on a 95 degree day with 70 percent humidity on the way to a vacation house when the caliper decided not to release due to the ridiculous phenolic caliper pistons. The other rear caliper eventually needed to be replaced too for the same issue. This was on a vehicle with less than 40,000 miles at the time.
