Basically a part I've ordered from the dealership keeps being pushed back and it's been A YEAR AND A HALF. It's the leather upholstery for the passenger seat. They were able to do the driver's side and that was January of this year. The dealership keeps giving me a date and it never shows up so they keep giving me future dates. Any idea how to best elevate this? I have 2018 Granturismo still under warranty but the dealership said they would still honor this warranty fix if the part is delivered after warranty.
