NHTSA Complaint #11499788 — 2013 HYUNDAI GENESIS COUPE

Last December, 12/11/2021, my son and I traveled from Pittsburgh PA to Columbus Ohio so he could buy a used car from a dealer. It was a 2013 Hyundai Genesis Coupe. We spent a few hours at the dealership, I co-signed for him, and he drove back the Hyundai while I drove my own car. Nothing was disclosed to us that we would have questioned. After a few weeks or so of driving the car, a mechanic looked at his car and told us it had been modified. I asked someone who had the same car/year/model and he confirmed this. This modification is significant, in the drive train/engine/under the hood/exhaust rather than something visual, on the outside of the car. It not only sounds far too loud as compared to the exact same year/model but drives differently. The mechanic pointed out the modifications under the hood and told us it should have been obvious to the dealer. I even googled photos of what stock engines look like and mine is definitely different. So, my son never registered the car in PA, as he wasn't sure what to do with it. He drove it for a few months for roughly 5000 miles as he had no other forms of transportation. He's been using my car instead. We can't pay for a car that just sits. It’s still registered with the dealer. The car has just been sitting because we're not sure how safe it is. One of the modifications that wasn't disclosed was a performance kind of muffler/exhaust. It is so loud that the driver can't hear sirens and horns. Also, we didn't know who installed these items. The driver could be exposed to dangerous fumes. We tried working with the dealer to no avail. At this point, we'd just like to return the car and get our money back that we paid the bank.
