NHTSA Complaint #11643892 — 2016 KIA SORENTO

As I was driving on the highway, my car began to lose speed. I attempted to accelerate but nothing happened when I pushed the gas pedal. There were no weird noises or RPM changes as if revving. I pulled onto the shoulder and slowed to a stop. If there had been more traffic on the highway I would not have been able to get to the shoulder without causing an accident. There were no warning signs or indicator lights before the loss of ability to accelerate. When I restarted the car, an "engine control" system warning appeared on the screen. I continued driving, staying in the right lane with hazard lights. The same thing happened a few more times on my drive home. I would lose the ability to accelerate, pull over, turn off the car, wait a moment, turn it back on and drive until it happened again. The car has not been expected yet but I have noticed small oil puddles when parked, which hadn't happened before this incident.
