| Description of the problem | After a few days, i had problems with the transmission; lots of downshifting affecting performance and braking. I had other issues as well, which none of them could be isolated. Hyundai of new port ritchey said they could not find an error code in the computer system and therefore, they felt there was no problem. After a few days and just a few hundred miles on the car, i attempted to return the vehicle for a refund. The dealer refused to take the car back and would not return my money. They basically said, you purchase it, you paid for it, you own it. So the problem is mine. |
