2021 Kia Stinger SUSPENSION,UNKNOWN OR OTHER,SERVICE BRAKES

Bought this vehicle from Carvana.com and have been trying to get it repaired since then. There is something wrong with the steering/braking/suspension system. According to License Mechanic Derek Hartfield at Monroe (248) 980-3262 after a road test - told me the vehicle is not safe to drive. He attempted to repair vehicle and Carvana denied the repair. Carvana instructed me to take car to Dealership, dealer has a wait list, I have a family and need to work. It feels like no one wants to help, and just keeps expecting me to drive from repair shop to repair shop. I just want to drive or they can take the car back if it is a lemon. At present the car has alot of issues and I dont know where else to turn. Issue: Vibration driving, vibration stopping, sounds awful when slowing down from highway driving, shakes with or without brakes, the rear wheels both lean inward when looking at the vehicle from the rear. Note: There was a sticker on the undercarriage of what looks like a repair on this vehicle on the rear right , which is odd because there is no history of accident. But accordingly, some repair was made on or about [XXX] to the Right Rear portion of the vehicle. I am not a mechanic so this is all frustrating for me. Car has been to shop since [XXX] located at 3939 Rochester Rd, Troy, MI 48083 6 times; +12483853735 - Monroe Mechanic determined vehicle has a bearing issue and is not safe to drive. Carvana denied the claim and ask me to take vehicle to dealer for warranty repair not considering my 6 visits to shop with three repairs. Vehicle was taken to Summit Place KIA on three occasions to make sure if was safe to drive located at 4200 Interpark Dr, Auburn Hills, MI 48326. +12486826002 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
