I have the 2014 GT+ tech as well.
2) my hood vibrates, even over tiny bumps. It's moving all the time. It makes me sad. I will have to have it looked at.
3) my mirrors vibrate, but not too bad. Both sides about the same, at 45+ they start to move a bit. At 60+ definitely moving.
My hood doesn't vibrate, but the mirrors do. I asked the dealer about it on my first service (7500 miles) and they contacted Mazda, and were sent some parts to fix it. I have an appointment for the end of the week to get it done.
5) the iPod limitation and screw up in the stereo really have me steamed. Had I known, I would have never bought the car. Absolutely ridiculous on Mazda's part that this slipped through.
The issues with USB and ipods are indeed annoying, and we all feel your pain. However its a real pet peeve of mine when people start complaining how they wouldn't have bought the car due to little problems like this. Really? I am very picky about my stereo equipment too, but, its a CAR... Also, if audio stuff is of key importance wouldn't you bring the ipod with you for a test drive before dropping 30 grand on it?
6) this is one of the cheapest interiors I've seen on a 'decently priced car'. Seriously, it feels cheap, hollow, and I have already noticeable squeaks and buzzes from several places.
This surprises me a bit. First, mine doesn't have squeaks and buzzes, so I don't know how I would react if it did. My parents have owned several generations of hyundai's and have been very happy with them, and while they drive great and are very functional, it blows my mind that anyone would think that the interior of any Hyundai (besides the genesis) is better than the CX-5 GT. I'm flabbergasted as to how you are coming to this conclusion. Is it possible your distaste for the soft-touch dash is bleeding over into everything?
10) seriously want to black out the rims
Go for it. I've seen a few of these done with plasti-dip and it looks great.
11) the Bose stereo is 'adequate' but not one of the better 'premium' stereos. Lacks much low end since it has no sub. Hard to get the settings to sound 'good' as it only has 'bass and treble'. Needs a midrange control.
Welcome to Bose audio. Their stuff always contains a lot of automatic sound shaping. It works the way you want 90% of the time but for the other 10%, people will hate it. If you still have the "centerpoint" feature enabled, try disabling that. I found it sounds much better without. The centerpoint is a positional "surround sound" like feature but I think it causes too high of a loss in sound fidelity.
12) the Bose Audio Pilot setting has absolutely no apparent effect on the sound quality at all, as far as I can tell
Its not supposed to. The audiopilot tunes the volume based on cabin noise, i.e. as you enter the highway it makes it louder.
16) I still haven't driven at night to see how the whole 'turning headlight' thing works.
One of my favorite features. Works great.
17) Wish the running lights and fog lights and stuff were HID to match the headlights. Looks weird to have them mix and match in my opinion.
Would be very cost prohibitive. You want to drop $2000+ for that? Search on here any you will find many people have replaced the yellow-ish running lights with clear. This can be done cheaply and I'd give this a try first and see what you think.
19) I hate. HATE. HATE HATE HATE HATE the soft touch vinyl dash. Impossible to clean, get dust off, etc. Seriously, this stuff was forged in hell.
This stuff will SURVIVE hell, which is the part you ultimately will care about. Use a swiffer duster. Cleans it like magic.
