So I purchased a new to me 2019 AT4 1500. It only has 6000 miles. Took it to dealer to do an oil change and check for any codes recalls etc. They found the rear heated seats not working. They have to snake a wire to the module then the switch to get it to work. The alternative is to remove the entire center console and carpeting out to get a new harness. $700 vs $? a lot they say. Anyway its a bummer. Im fixing it and wish I purchased a warranty for it. Im just reporting if anyone else had this issue. This way we can relate. Thanks.
