NHTSA Complaint #11476044 — 2016 HYUNDAI VELOSTER

I took my car to a dealer called Lee Johns in Everett WA for 2 recalls, but they told me I had problems with my catalytic converter and they replaced it under warranty at no cost to me. After 2 days they gave me the car and it did not work more than 2 hours and the engine light started blinking and from one moment to another it reduced the speed to 20 miles per hour. I called the dealer and they told me to take them, but to this day they only replied that the car warranty would only cover 55% for the replacement of the damaged engine. They gave me the defective car after they changed the catalyst and I gave them a working car that now doesn't work and they only tell me that I have to pay 4000usd so that they can repair it and they haven't given me any report of the engine revision because It failed, after they changed the catalyst, only telling me that I should pay and then make a claim or sue the manufacturer. I delivered my car to them on June 27 and to date they have it in their possession, leaving me unable to move and me having to assume the costs of renting and paying friends to pass their cars to me. I hope they can see my case since they wrecked my car.
