Engine Exhaust System problems of the 2013 Hyundai Veloster

During a normal drive from work, the car hesitated to accelerate from sitting at the red street light and white smoke began to come out of the exhaust pipe. There was no sign of car trouble,no engine light indicator nor any kind of acknowledgment that there was a problem with the car. I immediately coast to the nearest parking lot which was a holiday express hotel. I then called usaa and requested tow service to have towed to south towne Hyundai of riverdale, GA. On Monday August 12, 2019. I explained to the service representative of my issue. He called Tuesday morning and asked again what exactly was the issue in which I explained again. He never heard from the service representative again. I called Tuesday later that evening, left a message and no call back. On Wednesday, I called left a message with the service manager to give me a call and no one called. I went up to south towne dealership in which I waited and until I asked a lady who sat in an office next to the parts department for help. She went to the automotive garage came back and said they took the oil pan off saw shavings and noted it was a bad engine and the cost was $2500. 00 for the engine plus labor which would be around $5000 to $6000 dollars. I was shocked because I just purchased the vehicle less than a month ago and had not driving the car 1000 miles. I ask if additional test were performed she said no because the took the oil pan off first. There were no diagnostic reading, no oil check, no throttle cable check performed. I am lost because numerous cars are having the same engine issue and there was a recall for 2013 Hyundai Veloster turbo engine early this year however not for the non-turbo which is extremely unfair because of the shavings from the pistons which is not an oil change issue nor is it an owner maintenance issue and there were no warnings or sign of trouble.

Lag upon acceleration. Multiple cylinder misfires. All replaced and continue to misfire. To much oil being expelled through exhaust, regular oil change records and drive efficiency. Potentially ruining turbo as well as motor. Depleting mpg.
