NHTSA Complaint #11585740 — 2017 HYUNDAI SONATA

The engine was the part which failed. While driving the engine stalled and would not go forward. A foul smell was coming from the engine and the engine was rattling. The floor was wet on the passenger side interior. We let it cool down and took it to the dealer. They did not offer any explanation concerning why the car was not operating poorly or why the car smelled bad or why it stalled frequently and lost full power. Steve Taylor Hyundai service department quote "we don't know what's wrong with your car". It had 78383 miles on it. Taylor Hyundai said we can trade it in but you will have negative equity on your new loan. We were not credited for our trade in but we lost 4 or 5 thousand dollars on the trade-in. They did not cover the car with the warranty and did not repair it. The paperwork on the sale is quite confusing and does not make sense, but we know we lost money on the purchase of another car, and they did not honor the warranty. HELP
