I think its important to research a dealer just like researching when deciding on a vehicle. I even include when I was looking to purchase an ATV. The dealer I bought from has always been very good and when I needed work done on my ATV, his prices were very reasonable.
I have had my Compass for just over a month, its my first Jeep purchase. Prior to that I was always a Saturn owner and for the 28 years I owned Saturns, I was very happy with the vehicles. The dealer I bought my Compass from had good reviews and the salesman was also good. To be honest the main reason why I looked at a Jeep was the availability of a manual transmission. I have driven them all my life and did not want to give it up. He did not have one on the lot which was a surprise since he has a large inventory. In the end he did a dealer swap and I had my Jeep in a day.
The only mistake I saw was when I got my service contract paperwork from Mopar, they listed it as 5 years / 75,000, where I paid for the extended service for 8 years / 75,000. Went back to my salesman and within a few minutes it was fixed and I should get my updated paperwork in a week or so. He then was asking me what I thought about the vehicle, what I like and dislike and so forth. Since he already made the sale, I saw this as a positive thing that he wanted feedback that I liked what I bought.
The only downside I had with the experience is the lack of spare parts. I wanted a towing package for light towing and I was told it was not available with no ETA of when it would become available. So I have no idea how long it would be. I ended up getting one installed at Uhaul. It sits a bit lower then the OEM kit from what I am told, but I already test fitted my trailer and it is level with what I have. I don't plan to offroad with this vehicle where the hitch would possibly strike a rock or anything so its not a concern for me. Most I would do is off road is dirt or grass trail to park.
The spare tire kit is also not available and no ETA, that is a surprise, since they don't come with spares, the spare kit should be available for immediate purchase. Neither of these is the fault of the dealer, that would be Mopar.
I also have heard some of these noises as others have described, I can even hear the shifting, usually from 2nd to 3rd gear, but as long as there is no problem, I don't care, they are not that loud.
