I purchased the vehicle on 01/08/2024, less than 14 days later, the brake booster needs repair; it-??s currently making a hissing now as the air is leaking out and as a result, my brakes are not working properly.

My vehicle is a 2021 Kia K5 GT (2.5L-T), mechanically identical to Hyundai Sonata N-Line (2.5L-T). My car has 24000 miles on it and I have replaced the rotors on my car five times now due to premature warping. KIA OEM rotors, R1 Concepts, Brakenetic Rotors, all have warped. This issue is discussed amongst GT and N-Line owners heavily in the forums stating how the OEM Brake system has some sort of issue that causes premature rotor warp. Some have even resorted to changing their brake system to a old model Cadillac CTS-V system because of how crap these brakes are. Again after less than 2 months with new rotors, they have warped yet again.

While driving on 7/6/2022, upon acceleration, the vehicle began jerking and applying the brakes as if it was trying to attempt to avoid a rear end collision. Moments after that incident, the instrument cluster displayed warning lights of the following: check forward safety system, traction control, front end collision avoidance, electronic parking brake, and auto hold all in an orange color followed by a check engine light shortly after. Safety was put at risk due to the vehicle suddenly and uncontrollably braking without any warning on prior indication. The vehicle has not been inspected by anyone yet, but is schedule for a dealer diagnostic on August 9th, 2022. Currently, this vehicle has 10,900 miles on the odometer.
