NHTSA Complaint #11422177 — 2014 KIA SOUL

While driving on the highway in cruise control, the engine suddenly went into a lower gear and lost acceleration. Since then, the car has had difficulty accelerating and struggles to get up to speeds over 60mph. I had the car checked out and was told it was a clogged catalytic converter and that it needed to be replaced. Prior to the highway incident, the oil light would come on frequently and oil would have to be added every two to three weeks. The dealer has inspected the car for the engine recall and found no issues even though the car was experiencing oil loss when it was taken to the dealer. The car has 110,000 miles.
