I bought a 2019 Limited 1500 with 19000 miles and we have had trouble with a whistling noise that sounds like it's from the sunroof! We have had it in for repair 5 times and they think it's fixed but its not, the last time they said they have no idea what it is. I have contacted Ram customer care about a buy back but they say that the technicians at the dealership just don't know what they are doing and was also told the previous owner also had the same issue. I'm very frustrated as the noise is unbearable!
