Does this sound like normal engine noise to yall?

Bought this 2019 Hyundai Elantra from a Hyundai dealership 4 months ago; it has been eating through oil, I’ve already had to put 4 quarts in it. 2 weeks ago I checked the oil and it was nearly empty after putting 2 quarts in it a month prior. I put two more quarts in it and parked it for the past two weeks while I waited for the dealership to get me in for a diagnostic.

Aside from it eating oil, it seems to be driving fine. I’m not gonna lie, I am not sure of what my engine normally sounds like because I typically blast my music while driving. The check engine light came on last night, but when I took my gas cap off and put it back on, it turned off. I’m at a loss for what could be wrong with it.

I know the spark plugs and coil packs are due for a change soon; could this cause excess engine noise? The fuel efficiency is still really good, around 30 to 50 mpg.

Is this on startup? Or at normal operating temperature? Mine sounds like it’s tapping on startup and pretty much until the temperature needle starts to move. Once it’s at normal temp it’s quiet as hell. Can barely hear it running.

Mine does the same. I hear something similar to that on startup but once the car is warm & in motion, it runs almost silently.

@Taylor
Startup and normal operating temp.

Unfortunately that is not good. That is not normal, and whether it’s under warranty or not, I would still take it in to be looked at as soon as possible.

I also just realized we have the exact same engine, 2.0L Nu MPI, and my engine doesn’t sound like that and I have 113,000 miles. Idk about your model year, but the '17 with the Nu MPI engine didn’t have many problems besides oil consumption. Which my car burns 1.5 quarts between 3000 mile changes.

@Taylor
I did a VIN lookup on the NSHTA’s website and it seems like there was a recall for my engine due to the piston oil rings not being heat treated properly; which caused excessive oil consumption and engine failure. I’m really hoping that this is the case and I get a new engine for free. Otherwise I am likely screwed and have a $15,000 lawn ornament in my future.

Maybe look up your VIN and see if your engine is affected as well. You never know.

Edit: Upon closer inspection of the recall page, only years 2019-2020 Elantras are affected by the recall, so your engine is likely good.

@Jason
Sorry to hear that, hope it works out for you. I love my car, and have already dumped $3k into it to keep it running right. Just check your oil level twice a week and add oil when you need to. Hyundai engines are known for burning oil. I’ve owned 3 now.

@Jason
Also, most of the engine failures were because the engine burned oil down to critical level and starved the engine for oil causing engine failure. Make sure you are changing the oil every 3000 miles and checking your oil level frequently.

@Taylor
Yeah, I checked it once a week (every Monday) before I would go into work. That is how I noticed the excess oil consumption. Makes me scared to imagine what could have happened if I never checked it and ran it dry. The engine could have seized up while I was on the highway.

I’m lucky enough to have seen my brother run his old Cavalier dry before and completely destroy the engine; I didn’t want that to happen with my car. On that day I decided when I finally bought my first car, I would baby it.

@Jason
Good! I check mine twice a week because I drive far daily for work. Anyway, I’ve read tons of forums and threads about Hyundais, and one thing I’ve learned is regardless of what any manufacturer recommends for oil changes, do it every 3k and use Hyundai’s OE oil filter. These engines require it from what I’ve read. They said aftermarket oil filters can restrict oil flow, so they recommend using their oil filter. I had a scary tap when I first got my car but since I’ve been changing every 3k and using the OE Filter, I haven’t had any tapping noises. Hope it works out for you! Good luck and take care :v:

@Jason
There were some class actions on the NU that don’t show up as recalls. Do some googling.

Belt issues?

That is what I was thinking as well. It kinda sounds like a wum-wum-wum sound is coming from the engine when it idles, especially when I accelerate.

You don’t mention the mileage; you’d think a dealership would have made sure the belts were good, but who knows.

@Umbrielle
It’s at about 86,500 currently. I bought it at about 83,000. I have barely put 4,000 miles on it, and this issue occurred.

Common with Hyundai vehicles, this is a knocking sound and it occurs because of a piston slap. If your vehicle is under warranty, I’d recommend getting it looked at by the dealer; otherwise, you’re out of luck.

@Juneta
No powertrain warranty, unfortunately. I bought it about 4 months ago; you would think that they would address any major issues with the vehicle before selling it. The amount of oil it has been consuming leads me to believe that something was wrong with it before I bought it. Hopefully, this is something Hyundai takes into consideration when it gets into their shop. I don’t have the money to throw at them for a new engine, and I still owe a significant amount on the vehicle.

@Jason
Wow, yeah that’s weird, it shouldn’t be consuming oil. That’s a little concerning. Yeah, this has been an issue of controversy for Hyundai as many believe they should issue recalls when this happens but Hyundai won’t do that. I know of people who got newer models, and when their engine started knocking, had to fight Hyundai to fix it, where Hyundai would either put in a new engine block or even give them a whole brand new car, but that’s in some cases.

Sonata sounded exactly like that before it threw a rod. Have fun!!!:sweat_smile::sweat_smile:
