How do you inspect the piston rings without removing and dismantling the engine? Anyone with any engine knowledge knows that a failed piston ring = misfires, blow by, excessive oil consumption, and eventually a blown motor when the pieces of the failed ring get caught up all over the oil passages.

The resale value of EVERY Hyundai and Kia just plummeted. These things won't be touched in the resale market now. My wife loves her car, but hasn't driven it much so we have less than 2,000 miles on her 2019. And yes, to the others who mentioned it, I changed the oil at 750 miles as you're supposed to with a new engine. I wonder when the class action lawsuit will start?
Just plummeted................ Hyundai has had mass engine issues for the last 10 years, in a larger unit base then this one. Yawn, another on going Hyundai engine metallurgy issue. What else is new? The sun will rise tomorrow? If you have a late model Hyundai turbo motor you don't run into as many Hyundai metallurgy issues, since they use hypereutectic pistons in the turbo engines. The naturally aspirated engine get the soft very low quality pistons.

I believe my wife's 2020 Kona SEL 2.0L with 2900 miles has the piston oil ring problem, although my local dealer refuses to acknowledge it. I've posted a YouTube video of the noise it is making in hopes of helping me and others that may have this issue. Here's the link and description:


I would be interested to know if anyone else's Kona sounds like this.

So you already had it in for this sound? How long has it been since it was in for that? Are you burning oil and at what rate?

Exhaust leak? Sounds like 1 Cylinder

Yes, we picked up from the dealer yesterday. It seems to be burning a quart every 1500 miles and getting worse.

I had a 93 Escort GT. Developed a Knocking Noise at Cylinder 1. I was about to replace the Lifters. Then found a Bulletin from Ford concerning a Carbon Buildup. Ran a can of Seafoam through the Intake. Cleared it right up.

Isn't a quart of oil every 1200 to 1500 miles a bit excessive for a new car with 2900 miles? I get the feeling the dealer doesn't want to acknowledge or deal with this oil ring issue because Hyundai USA hasn't issued an official solution to the problem.

The Dealer has to follow what the Manufacturer instructs them to do. Oil Consumption test is part of it.

One thing is for certain: I'm not inclined to buy another car from a manufacturer that considers piston slap and excessive oil consumption normal. Nor am I inclined to recommend one to anyone else.

I have worked for Ford, Nissan and a GM Dealership in the past. Standard Practice.

Compression Check? Reove the Spark Plugs. Install the Gauge. Crank engine. See what the Pressures are? Low one is the Culprit.

I wondered if maybe you worked for a dealership in the past from some of your insights. What annoys me is they didn't do any of the things you mentioned. They only state they ran diagnostics (I assume OBD, which probably wouldn't show anything with this particular problem) and that they couldn't duplicate the knock (when clearly it is there, and there consistently for anyone to hear). I think we're going to try a different dealer or contact Hyundai USA Customer Service. My wife needs assurance the car is safe to drive and won't leave her stranded.

Sounds like a spun rod bearing to me. Post another vid with it reving to 2,000 rpm a couple of times. I don't hear an exhaust leak, I hear a mechanical knock.

It doesn't go away with RPM, just increases in frequency. I'll try to get a video up - good suggestion.

You also could have a cracked piston skirt, where the skirt is in the oil pan and the piston crown is still whole, BUT rocking in the cylinder.

That would be somewhat consistent with the recall - a brittle, damaged oil ring hanging on the cylinder wall and doing damage to the piston skirt. At this point I'm just happy that my wife and I aren't the only two people in the world THAT CAN HEAR this noise. ☺

Just changed my Oil and Filter yesterday. Magnetic Drain Plug was clean. 20k Miles on mine already.

20K miles with no symptoms yet sounds promising, as opposed to my Kona's loud knock at only 3K.. Hopefully the piston ring recall affects random people on the recall list and NOT EVERYONE on the recall list. So far I've been unable to get Hyundai (after taking the Kona to two different dealer service departments) to admit the knocking sound coming from my engine is NOT normal.

I have had other Issues. Steering Column and Brake Booster replaced. I am a Strong Believer in replacing the Drain Plug with a Magnetic one. Just incase. Had a 2015 Harley Street 750 which came Stock with one. And my current 2018 1200 Sportster has one in the Primary. Lets you know of any problems.
