My build date was 12/19 and told cannot be a vibration as it is outside the date they decided it was a problem.
I, too love so many things about the car, but opting to sell it. It is a family car, meant for family trips on highways that have normal posted speeds of 70. At 64/65 the vibration sets in & it is very, very uncomfortable to drive. So much so, that I took a 5 hour round trip and drove my 2010 Mercury Mariner vs. a brand new Palisade. Sadly, I found the car to be very painful in my hands, right leg (gas pedal), right foot, and lower back after 30 minutes at 65-75. I have yet to go over 77 according to the HUD--but any length of time is painful, uncomfortable, and has you tingling for some time after you get out. Not worth it. Dumping it while I can. After 3 months I cannot get dealer/service to say car vibrates or get Hyundai USA corporate to honor TSB/try to fix. Had a case number. Hyundai told me they will not buy the car back. And to prove them wrong. I contacted independent driveline/driveshaft place and they said car is too new and they could not get enough info on it. But read on-new car with lots of issues...cracked windshields, peeling paint, driveshaft or could be transmission vibration. Nothing being resolved by Hyundai USA. Just imagine your car fax when you do sell it it--will possibly state new driveshaft (s), new transmission--if you were going to buy this car used and saw that on a car fax, would you buy it? I would not. In car worlds this is referred to a POS (Piece of Sh**). Some are good maybe, some are not....buy IMO Hyundai has used cheap parts or thinner parts (paint and windshields) so it will be an ongoing problem. Choosing to dump this car now after 3.5 months and 866 miles! Even KBB cannot really put a price on these cars if less than 1000K miles.
