TIRES

This is not about a tire failure but rather dangerous mis sizing of tires from factory.I bought the car new. It was never in an accident or had a flat tire and did not have service call until this week at 13000 or so miles.the service included tire rotation and balance, but the service man called and said he wasnât going to do it because the driver rear tire was the wrong size!!!! It was supposed to be 275/40 R19 101W but was 245/45R19 98W. The two front tires are 245âs as they should be but BOTH rears are supposed to be the 275âs! Clearly this affects handling, wear, stability etc. Iâm a very careful driver but someone less careful could roll over on a fast corner turn! How many more Hyundai/ Genesis tires are mis sized? No one checks that when you buy a car!

The vehicle started smoking and stalled out Aug 18,2023. The vehicle starting shaking then I parked it for about two (2) hours. When I tried to crank vehicle again it wouldnât crank. I attempted to complete diagnostic test but the vehicle wouldnât remain on. I contacted dealership I purchased it from. They order a tow to be brought in. The dealership repair shop for about 3 weeks didnât know what happened. The change filters and oil change but it still was stalling.
