Good luck trying to repair your KIA under NAZA distributor. They are known to give shoddy after sales service.

Most likely ignition problem.

Could be ignition timing, spark plugs or distributor cap problem. The service centre should know what's the problem.

Maybe you can try using RON97 fuel which could prevent engine knocking.

How low is the RPM? Below 1k? If that's the problem, I suspect it's the gearbox problem whereby it won't downshift to 2nd gear when the RPM is low. It could be the amount of Automatic Transmission Fluid (ATF) is not enough.

If you're driving a manual car, try engaging 3rd gear & travel at 30kmh or slower.. Your car will jerk as if the engine will die off.

Hhmm... I think the best way for you is to go back to the Service Centre & lodge another complain. Keep pestering them until they solve your problem. Getting a new car with such defect is really heartache

Try to check the ATF level in your vehicle bro.

Glad you managed to solve your problem ;-)

It's lucky you managed to determined that your gearbox was filled with excessive ATF. If you keep on driving it in that condition, the gearbox will not last long ;-)

KIA comes with 5 years warranty right?
