Did you ever find out? Mines has this now


I would go to auto parts store and try some good "Lucas complete engine treatment" Hyundai recommends doing their version of this every 15k miles... Or something like that. I believe your engine is a direct injection engine and they can get finicky if they aren't taken care of completely, over time. When you use the Lucas stuff, add it when you need to fill up your tank. Fill up with a tank of premium. If you can go for a cruise on the highway for a bit this will help burn everything off better. Not 100 percent if this will solve it. It's a good easy place to start. It's also the least expensive option.


Thanks I put some premium gas in and it seemed to help a bit I'll go ahead and try your suggestion tomorrow.
