This problem seems to be getting more frequent. It’s a 2016 Genesis with the ultimate package. It’s really distracting going in a curve. I posted this problem in the G80 forum and a member gave me a link to a TSB on AboutAutomobile. I called my dealership about it and they said all car seats have some play in them. BS! He said there is no TSB. The number I gave him was invalid. He said bring it in and they would look at it. Is anyone having this kind of problem?
