I am very pleased with the upgrades of my 2017 Sonata vs my old 2011 but the new car appears to have more road noise than the old one. My husband noticed it during our test drive and had them balance the tires but it did not help. Don't know if vehicle noise insulation is enough in this model or the original equipment tires might be to blame. We did love the dealer and the deal and their selection was superior to other dealers.
