Kia rio5 LX 2013 started to make rattling / pinging noise in the engine at 70000 miles. I took it to the dealership was told they can't hear it. The noise started to get louder at 89000 miles brought it back to dealership and the technician said it's because of excessive carbon. Then was told to do decarb, replace serpentine belt, fuel tank filter & spark plugs and the pinging would go away. The pinging was still there but not as bad around 94000 miles brought it back for pinging had the technician ride with me and he agreed it was pinging all the time now. They did another decarb system on it and told me that its normal the car is going to ping and I should run 91 octane every 4th tank of gas. At 96000 miles check engine light comes on and it's knock sensor code they had to call North America Kia & Korea of Kia looking for answer to see what the problem is with my car. My Kia was at dch Kia of temecula for 7 days and they still couldn't give answer why or what was wrong with my car. They just said it was one of those issue that everyone was scratching there heads at. They used a top engine cleaner and the knock sensor code has been stable for now but the pinging is still there. They just keep telling me I drive to much & to use chevron techron fuel additive plus every 4th tank use 91 octane. I call Kia Consumer Affairs and was told my case is getting passed on to one of there analyze. Finally the analyze called me I asked him if he had my paper work he said no he didn't need it he talked to the technician at Kia of temecula and wanted to hear my side. I explained to him my issues and the analyze nick said so is the check engine light on? replied no he said so it's fixed then I explained to him no since Kia of temecula couldn't give me answer why or what is causing the issues of my Kia Rio. Nick said he would call me back, it's been 2 weeks no phone call back to me.

I was experiencing power loss and noises from the motor. I have taken this car in three times now for the same issue and the dealer (tempe Kia) says there is nothing wrong with the motor. The shop manager was extremely rude. The first time they took it for a test drive and heard the lifters. Took it back a month later and they say they hear nothing. Nothing was done with my car.

I detect a noise coming from the motor and went to service department of the dealer on January 14, they make a test drive and said that maybe the problem is with a "lifter" they gave me an appointment for service for the 28 of January. On January 22 I left my car at the service department a few days later, when I call for information they told me that the manufacturer decide to replace the complete motor due to a "recall" for some defectives on the unit that were posted. At this time I just know that the car still in service waiting for the motor. No warning lights turn on the panel ever and I just notice that the outside of the unit is too hot when I turn it off and park.
