2011 Kia Rio Engine problems

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...

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...

Ignition coils. Ever since I bought my kia in 2015 I have had to replace the ignition coils every 3-6 months. At first, when it was still under factory warranty, the dealership kept telling me they cannot find anything wrong with the car even though it would jump and even shut off on me when idling. It took 3 months of me taking the car back and forth to the kia dealership before the figured out what was going on with my car because the check engine light never came on. It turned out to be the ignition coils. Once...

I was driving and the car started driving rough and finally stopped.

Sold a car that turned out to be a 'lemon' after only a month of having it began breaking down the most recent issue being the cadillac converter making it a little dangerous to drive because speed is affected along with toxic fuel, whenever I drive up a hill the car is loud slow to where it sometimes rolls backwards or stops and at a green light car can not reach minimum speed cause other cars anger and strong fuel order sometimes when starting car, car cut off once at red light and when turning vehicle moves entirely too slow to when oncoming cars almost make contact

Tl* the contact owns a 2011 kia rio. While the vehicle was idling at any stop, the engine threatened to shut down without warning. The contact called a local dealer and was informed to have the vehicle towed to a shop, but the contact did not want to pay for the towing. The failure was not diagnosed. The manufacturer advised the contact to tow the vehicle to the original dealer. The vehicle was not towed. The failure was not diagnosed or remedied. The failure mileage was approximately 62,000.

I'm really not sure what's wrong with it bit this is way happened. I was driving to workfrom lunch wasn't having any problems then all of a sudden the engine light stayed flashing. In the 4 mins that followed my car started loosing power so I pulled over to a gas station once I stopped the car I heard a knocking sounds and then the car shut off. There was oil, it wasn't black, it did not have white spots and there was no smoke v of any color coming from the hood or tailpipe. What was weird was that the antifreeze...
