    The worst issue I have with my car is the cooled seats only work on the cusion part of the seat and not the back rest. It's super annoying because the back part actually gets hot if used for more than 20 minutes or so. Also minor but annoying, the wheel gap is higher on the front than back of the car so it has a reverse rake effect.

    Edit: How could I forget the dash rattling? That is also really annoying on a 40k plus car.

    You know a TSB is out for this, right? It won't make the coolers 100% better but it should at least keep the seat back from heating up.

    Is there a website that lists all the TSBs for the S550? I googled with no luck.

    Yeah I've read the thread about it, thanks. The general consensus seems to be that it's not worth the trip to the dealer so I haven't bothered yet.

    No regrets!

    I have a mid MY2015 GT Premium 6M 3.31 Almost 5,000 miles /8,000km on the odo.

    Three issues for me.
    1.) Vibration/drone on the highway most noticeable at 110kph or 68Mph.
    I balanced my own driveshaft in one afternoon which makes the car smooth and drone-free at any speed.

    2.) Minor trunk gap issue (rubs a tiny bit in one spot when opening/closing) Dealer will fix, or I may make a small adjustment myself.

    3.) Parking brake handle is not held down very well when parking brake is disengaged, so just bumping it with my leg can move it enough to bring on the "Parking Brake" warning light while driving. (this will shut off your cruise-control if it is being used) A couple of times the light/chime has come on without me touching it. Will require a small parking brake adjustment to correct.

    I have no regrets buying this car. It is great fun to drive and I still get compliments on it even though these have been on the road for about two years now. Pretty much everyone agrees that it is a great looking car. The 5.0 sound-track is fantastic!

    Thank you for your input! I am going to be looking at a 2016Gt (used 6k miles) on Friday. I am in WI and the car is in Missouri, so I am traveling 500 miles to see this car. i have the exact same concerns you did. YOu have reinforced many of the things I have been thinking in regards to checking out the vehicle...I am hoping I won't be disappointed, but not afraid to walk away.

    The panel alignment issues for me ended up being adjusting the hood bumper stops and correctly positioning the driver's side tail light. At first I thought the trunk was misaligned, but the body shop owner showed me what it really was, a misaligned tail light.

    In the end, minor issues that were easily fixed. This car has been the best car I've ever owned. ...and this is after owning nothing but GT500s (several) from 2009 to 2014.

    Not off the top of my head. Its listed in the Issues/Recalls section on this forum though.

    If you're in for a regular service or for something else, I'd have it done. Like I said, it should at least keep the back of the seat from getting hot.

    No issues whatsoever.

    I've driven it 29,500 miles -- including a road trip from NYC -> LA and back -- and haven't had to do a single mechanical repair, other than oil changes. Gotten a bunch of flat tires, though (screws in the street are terrible things).

    I have a couple of cosmetic problems -- once I bumped a car in front of me parallel parking, and the passenger-side attachment of the front bumper is now slightly out of line. Somebody tried to throw a concrete block through the driver's side window to break in to the car, and while the window didn't break, it's got some scratches in the side that eventually I'll have to replace the window to fix. But no mechanical issues at all.

    The dash rattling started for me around 10K miles, but it only happens on certain types of pavement. It comes from the light switch; not a big deal.

    I get this on occasion. If I tap the plastic panel with my finger a few times, it goes away for a few weeks before I'll hear it again. Hasn't annoyed me enough to delve into the cause/cure. :)

    I started the feel a slight driveline vibration after 5-10k miles. It's a bit annoying on long highway runs, but again, not annoying enough for me to look into it further. When I replaced the tires at about 21k (the stock tires suck, BTW) things got noticeably more quiet, but I can still feel a slight vibration up around 60-80mph.

    If I could go back and do it again, I would have swapped the tires immediately. Got Continental Extreme Contact DWS06 now and they are head and shoulders better than OEM.

    Best,

    My car has been just about flawless. Had the early brake squeal recall done, but that's it. I don't think there's any issue that affects a majority or even a large minority of the cars.
