2022 Kia Stinger Brakes Problems

I brought my 2022 Kia Stinger GT -2 in to Greenway Kia, West Palm Beach FL on 02/20/2023 for routine maintenenace, check front end alignment and brake check as there was significant vibration while applying breaks and choppy breaking. The mileage is 4000 and driven primarily city/low speeds. Later that day I was told that the rotors needed to be resurfaced as they were warped. I questioned how a new $70,000 vehicle with low milage could have warped rotors this soon, as I work from home and rarely drive it. I was told by the service manager that this was a design flaw in the Kia Stinger and the vehicle should have been fitted with high performance slotted rotors by the manufacturer. I was charged $425 for the resurfacing because the 12/12 waranty has expired on the exact day the car was brought in for service. I stated that 12/20/23 does not end until midnight and I should not be charged anything for a design flaw in the vehicle, particularly a safety flaw involving the breaking system. The service manager stated that they have had similar issues with the Stinger GT with low milage as well and that I would have to file a compliant with Kia Motors. I do not beleive that I should have been charged anything for this repair and that the vehicle Stingers should be recalled due to being a safety hazard to owners as well as other motorist's on the roads. A high performance vehicle; 6 cylinder twin turbo with 368 HP 3.3 L engine should have appropriate and safe breaking system to stop the vehicle. Aside from the vehicle being unsafe with innapropriate rotors I believe that I was intentionally ripped off by KIA Motors, Greenway KIA or both. I advise all vehicle consumers to consider these facts before purchasing a high performance Stinger, or fo rthat matter any KIA product
