NHTSA Complaint #11623218 — 2017 HYUNDAI ACCENT

My catalytic converter failed on my car and will eventually needed a new engine. I was driving a busy road doing about 55 miles per hour and my car suddenly dropped down to 3-5 miles per hour without warning now flashing light on the dash nothing. I could have been killed or hit causing a multi car accident. I was so scared and it was so hot I thought my engine was going to blow. I coasted back into the auto place that just preformed my oil change thinking they had done something wrong. They did a throughall diagnostic of my car and my car was read that my catalytic converter was bad. So I then got my car to the Pearson Hyundai dealership where there formally diagnosed my car stating that I needed to replace my catalytic converter for 2500 - 3000, but I had done my research and new it was a known problem. People in several Hyundai Forums have been complaining about this same issue. I asked for assistance in getting my car repaired from Pearson Hyundai, Hyundai USA, and I even wrote a letter to the CEO of Hyundai to no avail. I have been without my car since June. Hyundai has a real issue with oil consumption, bad catalytic converters and they need to replace my engine warranty or not. I feel my vehicle is very unsafe and I am nervous to drive it. I can't drive it if I wanted to more then a few feet because it chokes up and the goes 3-5 miles per hour feel like it is going to die at any moment. I am asking that Hyundai take ownership of it's faulty car parts and do the right thing by its consumers. Anything could have happened to me in that day in June and it seems nobody is worried about it. Hyundai can not just pick and chose who gets a replacements when other models are having the same issue. There were no prior warning lights or signs other than the error code that the auto place provided.
