 I have had 3 Santa Fe Sports; 2013, 2014 and now 2017. The 2017 is by far the worst. I bought it in April, 2016.  First, the AC/heat smelled like vinegar and mildew within months of purchase. Brought it in numerous times and now the odor is better, but sneaks up every once in a while.  The car started making a weird noise from the undercarriage  at slow wide turns about 5-6 months after purchase and they can't figure out what it is...they "cannot duplicate" despite it being heard on test drives with, yours truly! They did lubricate the struts because they did "diagnose" it the first time, but that did nothing but waste my time. The car also vibrated so bad I couldn't take it on the highway and brought it back THREE times to be fixed. Now, the steering wheel vibrates at about 30-50mph and I was told today that it is normal for this vehicle...oh, that's nice! The car has already had a transmission software update recently because it shudders, it felt like it was about to stall and it bucks and the RPM would jump up and then back down...those things have since improved, but still not gone. Oh, a transmission or engine problem? No way! (according to them!) Sometimes when downshifting it also feels like it's kind of speeding up! I live in Florida so it does not get that cold, but the car does not start up easily when it has been cold. I'm beyond disgusted with this car. Oh, and by the way, I've had my radio system replaced because the displays weren't displaying correctly, the android auto wouldn't connect or it would lose connection, the reverse camera went black and white on me at one point, etc...I'm actually at a dealership now and was told "could not duplicate" some,ofnthe above issues. Surprise!  I'm looking to trade it in at this point, of course for another brand. I don't want to drive this thing anymore. I don't trust it, nor do I trust Hyundai at this point. It's a beautiful, roomy, car and the touch screen is very simple to use so those features get 5 stars. Otherwise, blah! I'm beyond dissatisfied
