Transmission Failure problems of the 2020 Jeep Cherokee

I recently had a svc 4wd light come on in my 2020 Jeep Cherokee which has 75,750 miles. Then while driving a warning light kept coming on telling me that the 4wd service is unavailable and to service 4wd. Well - I took it to the dealership and was told that the ptu needed to be replaced and that unfortunately it was not covered under a recall because it only covered the years 2017 - 2019 and some 2020 Cherokees. I feel that this ptu that is defective should have a recall issued for the 2020 year as well since it's unrealistic to think that the ptu would fail on a vehicle that has only had the 4wd even used maybe five times in a 4 1/2 year span. I would like you to check into this issue that I feel should be a recall and would/could cause serious accidents due to sudden loss of power, or ability to move vehicle due to transmission failures. I feel that Jeep/Chrysler knows about this issue and have been slowly issuing recalls, beginning from 2014, then 2016 and then 2017-2019 and now I feel the 2020 and possibly later years should be covered. I was at the dealership 4/30/25. At this time I cannot afford to repair this ptu issue and am taking a chance to continue to drive my vehicle since mechanically it is working right now - just providing me with the warning lights/beeps. Please look into this and advise.
