Very occasionally, as in 6-7 times in 18 months our 2006 Kia Rio 5 (manual trans) has experienced a sudden 2-3 second loss in engine power. It feels like the ignition is suddenly cut and the car decellerates quickly, not really dangerous on the highway where momentum and 5th gear keep you rolling, but around town in 2nd or 3rd gear it's certainly a big surprise for anyone following too close behind you! If in a high gear like 3rd, 4th, 5th, if you just leave the clutch engaged the engine will restart within seconds as vehicle momentum keeps the engine turning, if in a low gear you are forced to disengage the clutch, the engine will stop, but banging the clutch back out will "bump start" the car immediately. We really like this little car, besides this and it's reluctance to go into reverse it's been tremendous. Thanks for reading, anyone have info about this power loss?
