United States, I'll post back what they say.

The dealer was rude, but he said that it's possible that just replacing the oil filter will solve the problem. I asked them to do that first, since it would be a $25 fix. I've been having the oil changed by a national chain place, using the correct oil viscosity and whatever brand filter they use. If the problem persists even with the correct filter, I guess I'll keep pressuring them to solve it, because it's getting progressively worse.

Do not compare fuel prices just converting from one currency to another.

What is an average salary of full time employee (let say bank teller or pick any other profession) in those countries?
How much fuel they can buy with monthly paycheck (net, after all taxes and other bs)?

Then compare who pays the most...

Picked up the car last night, heard exactly what I expected: "Couldn't reproduce the noise." They burned up a quarter tank of gas, so I'm guessing they just ran the engine at different RPMs without driving it, since the fuel economy gauge went from mid 30's to under 10 when I picked it up.

So, they changed the oil ($40 for a conventional oil change? Robbery.) and said the car sounded fine. I pulled out of the dealer, drove about 30 feet and "ting ting ting ting" again.

Going to go back to the dealer on Friday and put a technician in the car while I reproduce the sound. I don't think it has anything to do with the oil/filter, because the noise only happens under certain load conditions. If there was internal engine damage, it would happen all the time, rather than only under certain conditions. It's also possible that it's the transmission, the noise varies in pitch from a soft ticking/thunking noise to a higher pitched metallic sounding pinging sound.

You just described my experiance with my dealer to a tee except I returned right away and had a tech ride with me. I was able to reproduce the sound within about 50 feet. He told me it was probably "combustion echo" that it was common in 4 cylinder engines and "what do you care anyway, you have a 100, 000 mile warranty".

Not a satisfactory response but I also knew I had gone as far as I could with this avenue.

Heres hoping you have better luck.

I would be willing to accept that diagnosis if the sound was consistent, however, in my case, it's not. That, and it's getting worse. It started off only happening once in a while, now it's happening pretty much all the time.

I'm sure that's what I am going to be told, that it's "normal" and when my engine blows up in a few years, they will try to blame it on poor maintenance. Save your reciepts, records and who you talked to and when, I get the feeling this is going to wind up in court.

what you're describing is 'knocking' which is either pre-ignition (very bad) or detonation (bad but not AS bad) which you don't want in any engine, regardless of the length of warranty like you were told by that champion of a mechanic. The discretion between the two possible issues is to do with which cycle the piston is in at the time of the unwanted explosion. When fuel is ignited in a normal cycle, it combusts which is a controlled smooth burn. When it ignites due to knocking it is a supplementary out-of-control explosion which causes (among many other mechanical stresses) the engine to resonate due to the huge spike in cylinder pressure, and makes a metallic noise that you hear as pinging.

The solution is running on premium. Premium fuel can take more compression before it explodes, making it less volatile and less prone to premature ignition. Mine's been on it for most of it's life due to the same problem you have. It sucks because no one will admit the engine is basically tuned for 95-98RON, but it is. It runs smoother, has a quieter exhaust note, has more response and feel in the throttle, instantly, not over time like a car not tuned for premium slowly seeing benefits.

Was your car due for an oil chance? or did they just take you up the garden path? Very hard to find good mechanics these days. You know, the ones who actually know about cars.

Run it on premium, your issues should go away.

OzSLS, I know we have discussed this in other threads. I did take your advise as well as the "champion of a mechanic" as to running premium fuel. After three tanks, there was little to no difference so I switched back to regular. I dont see any reason to spend the extra money and not achieve any results.

To me it just seems to be one thing after another with Kia. Fuel economy, fuel grade and oh yeah you can only use our oil filters in your car but we aren't going to tell you that until after the the purchase and you possably do damage to your engine.

Honestly unless things turn around big time and quickly, this will be my last Kia!!!

I've run premium, top-tier gas without resolution, and I've run fuel system cleaner as instructed by the maintenance manual, and the noises are still exactly the same. ><

It was due for an oil change, which is why I didn't mind paying a little extra to have them do it, since according to Kia, the filter causes this problem. The noise has a few different pitches/tones, there is a plastic-y sound that sounds like putting a baseball card on the spokes of a bicycle wheel, and a more metallic sound similar to taking the tab off a soda can and dropping it inside and shaking it around. It only occurs when the engine is under load (doesn't happen if you rev the engine while stopped) and the engine RPMs are lower and close to triggering a shift. I've noticed that the sound will immediately stop and the engine sounds fine as soon as the gear shifts up or down.
