I was driving the 2014 kia sorento on us27 in cincinnati, ohio (55mph zone) and all of a sudden the vehicle slowed (i wasn't pressing the brake pedal) and the vehicle stopped in the middle of a busy roadway. i had to floor the gas to get it to move to the side of the roadway. there was a odor of something burning when i finally got out of the road. the traction control light was illuminated during the time. the vehicle had to be towed to a local kia dealer. they said it had 5 major codes on diagnostic, they couldn't duplicate the problem that lead me to the dealer. but they wouldn't return the vehicle due to safety concerns.
