Air Conditioner problems of the 2016 Jeep Renegade

While idling at a stop light, the cooling fan could be heard making a weird noise, followed by a strong odor. This happened one time earlier while idling and the air conditioning was on. The strong odor made me take it to a shop near me for fear of driving it. Luckily it was colder than usual or it would have overheated. Upon looking into the issue and having my cooling fan replaced, I found it was a common issue in the 2016 models, and has been fixed for (or part of) the 2017 models. I checked with the dealership and they confirmed no official recalls were sent, and I don't understand why. Luckily, I got this replaced before something bad happened, but I've spoken with numerous other Renegade owners who had the vehicles break down and had to be towed to shops for repairs. I did have an extended warranty, but because I took it to shop near me (for fear of driving it) instead of the dealership, they only covered part of the repair which was about $200 out of my $550 bill. I don't understand why these are being left out on the road when it is a known issue. The dealer who provided the part even had multiple fans in stock, indicating this is a common problem.

Air conditioner wont hold anti freeze. Dealership says the ac compressor unit has shrapnel in it and needs to be replaced and they would not do it because it happens to ac units sometimes and not covered under warranty. (ac units should last longer than 3 years!).
