 I traded in my 2014 Sonata Limited 2.0 for a fully loaded 2015 Sonata Sport Ultimate 2.0 in January.  I have regretted this purchase within a week of purchasing this car.Pros:  solid acceleration, roomy, beautiful Orange color, fairly pricedCons:  the panaramic sunroof has rattled since the 3rd day of purchase, Hyundai isn't sure how to fix it. My Antenna had to be replaced due to my GPS not working properly and not my blue link app won't connect to my car.  The engine sounds like it is a diesel, it is loud and shakes violently from time to time, all of which I was told his normal.  They blame it on the high pressure fuel pump.  The road noise is louder then advertised.  Now my keyfob won't lock my car. I wanted to love this car, I really loved my 2014 but I wanted the Orange sport model.
