After several times that the engine stopped running and kia dealership couldn't find the problem, as I turned into the dealership the engine stopped running and I coasted into the parking lot. Repair order stated possible solenoid failure (code p0665) and replaced bank 2 intake manifold tuning valve solenoid. This was on 10/2010. The car was bought by us as new. Again, the engine has stopped while decelerating and/'or turning (Dec. 21, 2011). This is the third time in 3-4 weeks. Called kia consumer telephone number in owner's manual and they have no other incidents reported for this problem. Car know has 90,000 miles on it and they said we're out of warranty and we should take it to our kia dealer in our town. Called them and earliest appointment is next week as their technician is in school. The wife and I are worried that we may be "rear-ended" as this happened on a busy highway, as we were braking to stop at a traffic light or turning into a driveway.
