purchased brand new December 2022. 7000 miles had issues with brake noise. dealership resurfaced rotors. 28000 miles turbo had to be replaced due to "reduced engine power". Was told a seal was the problem in the original design. 45000 miles a/c would stop blowing and produce extensive condensation on middle vents and "shift to park" became a problem. dealership cannot "reproduce" issues and therefore states nothing is wrong, although research shows problems exists and there is a back order on switch/shift assembly. Hopefully these problems "show" themselves to the technicians before extended warranty runs out, better yet a recall be issued.

Shift to Park error message when car is already in park and then difficulty getting car to turn off. This is an ongoing issue. I have seen online this is a common problem. This is a safety issue because if the car doesn't turn off the battery will go dead leaving a driver stranded. This issue began soon after the car was out of warranty.
