Damn breh. That sucks. I think #1 and #3 are probably related. How has the car been riding since the change of spark plugs? Did you get them changed yet?
That sucks to hear about the interior issue. Those sounds are irritating and can make cars feel faaaar less premium than they are supposed to be.
I've never liked the CUE system. I've heard it's been slow since the since the start, but it was supposedly upgraded in the latest CTS (I don't know if this was applied to other vehicles as well).
On a scale of 1 - 10 how satisfied are you, and are you thinking of getting another vehicle entirely?
Well the engine still runs rough at idle a bit, I've accepted this but otherwise I haven't had any issues since they replaced the spark plugs.
I actually like the CUE system, for what it is its cool but it could be way better if it was faster and responded better. I don't think it's a bad as magazines and people think it is. I've tested CUE on a 2014 model and it was way faster. If they ever add apps and stuff like that said they would do it would be dope.
Also I forgot to mention whenever I have the heat on, after some time it will eventually start blowing out cold air and turning it off and on doesn't work.
Overall, I really like the ATS but mine has too many issues. I love the exterior and interior styling and love the Caddy brand so I'd get another one but not for a few years. I need them to work out the problems. Best handling in the game too, get tons of compliments but I'm ready to get a different whip.
