Engine Rattling And Whining Sounds problems of the 2017 Hyundai Tucson

Vehicle is 2017 Hyundai Tucson with just under 60,000 miles on it. Maintained with regular oil and filter changes. While driving the vehicle 4 days ago, a rattling noise was noticed coming from the vehicle. When coming to a stop, vehicle started to almost stall, then engine and rpms raced, no indicator lights. Called the dealer that it was purchased from to have it looked at and schedule oil change service that it was just about due for, a recall to be done and have the issue looked at. Appointment was scheduled for the following week, but the vehicle didn't make it to the appointment. Yesterday, I drove most of the day with no issues, then suddenly when coming to a stop, started hearing a rattling and knocking coming from the engine really bad. Vehicle started to stall, still no indicator lights on. Vehicle did not stall and started going again until I started to slow down at another stop sign. Oil light started flashing erratically, engine light came on and vehicle died on the side of the road. Called dealership about the issue, they had me contact Hyundai roadside assistance to tow the vehicle to the dealership. Upon arrival at the dealership, the service advisor, before even having the vehicle checked out, stated that it's going to need a new engine, as if they are already aware of the issues concerning these vehicles.
