Coils, I have been through 6 sets of coils since I bought this car in 2011. This causes the engine to run rough , sputter & have no pick up when trying to accelerate. The 1st set I paid the dealer $125 a piece bc they said I must replace all 4 at once even though when 1 coil burned out under warranty they only replaced the 1. I got smart after dealing with the dealer. I bought lifetime coils from autozone and about every 1.5 to 2 years I am replacing them. It's easy to do but thats not the point. I've never had or heard of any car doing this except mine. And please let's not talk about resetting the computer brain. That is an impossible task in LA the land of teaffic....please take a moment & read the hoops you have to go through on kia's Rio forum. After trying to get my car slogged for a year I paid a guy 135.00 gave him my car for the night so he could do it. Utter [XXX] !

The engine and all electrical shuts down without warning. This happened three times in heavy traffic and nearly caused an accident. The engine stops running and the electrical components turn off which shuts down power steering and power brakes. Each time this has happened the electrical is disabled and the car is completely dead with zero response when the ignition key is turned; no dash lights, no starter, no power. After the first incident the plugs and coil packs were changed out. After the second incident the fuse block was changed out which was said to have been overheating. After the third incident the car was parked and has not been driven since. After the "dead" car is towed and it sits for a couple of hours it will start again and run for indeterminable amount of time before shutting down.

AS I WAS DRIVING STRAIGHT THROUGH AN INTERSECTION OF WHICH I HAD A GREEN LIGHT, THE VEHICLE COMING THE OPPOSITE WAY THROUGH THE INTERSECTION FAILED TO YIELD AND TOOK A LEFT TURN HITTING ME HEAD-ON. WE WERE EACH GOING BETWEEN 30-35 MILES PER HOUR. I SLAMMED MY HEAD ON THE STEERING WHEEL, SHEARING MY BRAIN FROM THE INSIDE OF MY SKULL RESULTING IN A MASSIVE INTERNAL BLEED. I ALSO SUFFERED A SEVERE CONCUSSION AND TORE SEVERAL LIGAMENTS IN MY NECK. I CURRENTLY CONTINUE TO SUFFER FROM TERRIBLE MIGRAINES AND HAVE BEEN UNABLE TO RESUME MY PREVIOUS PROFESSION AS AN ARCHITECT. WHY DID MY AIRBAG NOT PROTECT ME FROM SLAMMING MY HEAD ON THE STEERING WHEEL? IT SEEMS MY AIRBAG ONLY PARTIALLY DEPLOYED. I REMEMBER IT TOUCHED MY FACE BUT DEFINITELY DID NOT PROTECT ME FROM HITTING MY HEAD ON THE STEERING WHEEL. I WAS IN A SERIOUS BRAIN FOG FOR MONTHS AFTER THE ACCIDENT AND MY LAWYER MIS-ADVISED ME IN NOT PURSUING LEGAL ACTION AGAINST THE AIRBAG MANUFACTURER. NOW THE CAR HAS BEEN SOLD FOR PARTS.
