NHTSA Complaint #11474427 — 2011 KIA SORENTO

Driving the vehicle on a two lane road at approximately 50 mph (steady cruise state), the vehicle experienced bump or jump in the powertrain (shutter). I immediately lost power to continue at the desired speed (engine missing or lack of power). I slowly tipped into the throttle, but the vehicle was not responding as expected. I put the vehicle in neutral and slightly revved the engine to see if the engine would run normal without load, and it would increase in RPM, but not smoothly. I let the engine return to idle and the engine stalled. I lost my power steering and power brakes and had to muscle the vehicle into a parking lot where I was able to bring the vehicle to a stop and put it into Park. While this event took place the engine or vehicle warning lamp was on the instrument cluster. I got out of the vehicle and looked under hood to see if I could see any obvious signs of an issue and found nothing. I then restarted the vehicle after having the key in the off position. It started and seems to rev up normal. I put the vehicle in drive and cautiously drove the vehicle to my home (about 3 miles). There is no sign of the issue and no lights on the dash. This is not a condition I would want my wife or daughters to encounter, as it produced no warning leading up to the event. The loss of power steering and brakes makes the vehicle difficult to maneuver in a safe manner. It's difficult to trust this vehicle now. The mileage is 92K.
