I assume you mean this thread as some sort of statement to counteract the issues others have, and not as something intended to make you feel better, right? Because everything is good so why worry?
As with nearly all forums I've both participated in and run over the many decades, the preponderance of folks who come here do so because they have problems. It's like if you only ever visited hospitals you'd think there were no well people anywhere in the world. So of course we are going to see horror stories here because, frankly, the amount of folks like you and I who say "Hey, just wanted to drop by and say everything is fine!" is pretty small (and we're weird, anyway. Besides, I first came here looking for some minor issues with Maximis, like my arm rest, and for advice on window tinting and such. So, again, wasn't just coming to tell everyone I had nothing to tell :>).
We have about 1400 miles on in a month (which is really high for us but mostly because we made a lot more trips into Orlando than we normally would, to get the windows tinted and the slight cosmetic issue on the car fixed). No issues other than the NAV system went "south" on us, but was (apparently) fixed by the dealer with an update to the system. I also couldn't get the voice in the system to lower after that, but that's because (again, apparently) they put the beta version of the new MFT system (which no one other than beta testers are supposed to have) and it had new options which even the first SYNC tech person I talked to couldn't figure out (but the second one knew and now all is well). I don't see either of these things as huge, because there is a LOT of tech in these cars and as an ex-IT person I'm used to the issues that come with that (with great power comes great...issues?). Heck, I still have issues with the fairly sophisticated stereo system I put into our 15 year old Durango (when we had it in for repair they somehow "rebooted" it and I'm struggling to get it back to how I had it fine tuned).
Our lifetime average right now sits at 43.5 but we constantly run A/C high (as you most likely do in our area) and while my wife insists it is MY car she likes to drive it and Lead Foot Annie always brings down the average every day she does (so I'm constantly in a catch up game to her). I really think if I were the sole driver I'd easily have 47+ mpg on it right now, as even with an even mix of city and highway I get in the 50's most of the time (and it will only improve in our mild Florida winters, when no A/C and no heat are needed).
