Rio

  • miles
I had driven my wife to her school about 5 miles and headed back to my work another 5 miles when i tried to accelerate pass car I lost almost all power barely making it up a slight hill I kept going trying to make it to my house barely going 10 miles an hour. I thought the transmission had let go cause while I had the gas peddle floored i went at best 10-15 miles an hour I eventually parked the car I knew it would never make it up another slight hill. It was rowed to a nearby dealer where they could find no problem telling me it was just some bad gas. This sounds like what I read about today with a couple of other models of Kia.
