2023 Hyundai Sonata Engine

My car was having an issue where it was losing all the coolant, causing my engine to overheat twice while driving down the highway. Unfortunately I couldn't find a leak anywhere and there was no fluid leaking in my garage. I lost an entire reservoir of coolant overnight. After taking my car to the dealership to get repaired, I was told that it was leaking my coolant into the exhaust system and burning it up. I was also told "it was a know issue, they had a bulletin from Hyundai on how to fix the problem, and Hyundai completely redesigned the part to stop the leak and it had to be special ordered." I was without my car for a week and left with a $1300 bill as apparently it was not covered by my warranty. I have no idea how a known issue is happening so frequently that requires a nationwide bulletin and a part redesign, yet somehow is recalled. Especially considering it left me stranded on the side on the side of the highway in Indiana during a snow storm but someone seriously needs to investigate it.

Coming home from work I stopped at a red light and when I tried to accelerate the vehicle was surging and jerking shaking and wouldn't pick up speed 2 min later the check engine light appeared flashing thankfully I was 5 min from home got the car towed the next morning to hyundai dealership said it was an cylinder misfire the car only has 30,000 miles on it
