I have a 2019 Jeep Cherokee that’s having that same problem! I originally noticed blower motor issues within the first few months of owning it, and the dealer told me it was a cabin air filter issue...I bought it brand new....but changed the filter anyway. Then after 42,000 miles it’s completely stopping, after I’m out of warranty. The radio randomly turns very soft, and the screen shuts off too. Don’t worry there’s never a problem when they have it, and if there is there’s always a magical update that doesn’t fix a single thing.
