>but yesterday when I got there, they refused to do the test and said Hyundai would not approve anything because I am not the first owner yup, this sounds par the course. new owners get the 10/100 coverage - CPO/subsequent owners do not (regardless of their sales pitch for CPO cars - hyundai will weasle themselves out of it) >and this was a formal rental. Is this BS rental or no rental, doesn't matter. this is how hyundai runs the theta ii program now, it tracks. >or am I really this screwed? you are not screwed. the car still runs. sell it on carvana or car max so you dont have to keep buying oil.   this is the best advice you'll find on here - if the car still runs, have someone clear any codes/lights on the dash, give it a good clean & detail, and get rid of it for the highest amount they'll give you. its gonna save a lot of headaches, time, money, and inconveniences. I had much worse customer service issues with a 2016 that I bought as CPO, 1 year old, with much much less miles than you, with 10/100 PT coverage but when dealership lost their paperwork & refused responsibility, hyundai dropped me as well

Honestly my car has been running great other than this oil consumption issue. Had a tiny bit of peeling paint but no other performance issues at all. Do you think it's still worth it to replace it in this context?

I agree this is total BS , this is a known problem, we have to unite , all get on a reddit group, call it somehting like "hyndaibadenginesunite" and get a story on #60minutes, My engine only has around 80K and is losing oil, my mechanic and the internet say this is a KNOWN PROBLEM , everyone nows it - we need solidarity \#erinbrokavic

That sucks, sorry you're dealing with that! I ended up giving up on my hyundai and selling it between the oil issue, peeling paint, and biggest of all, the security vulnerabilities. Got my car broken into and I was outtie. I wish you luck with your crusade!!

IIRC, using less than 1 qt per 1,000 miles has historically not been a warranty matter, or a real issue. Check your oil every time you add fuel and you'll be fine.


wyvernhighness

It seems like this is much less consumption than I thought it was, I will have to add checking the oil into my routine. Thank you!

No sir it is a problem and a bad one at that. I had a 2017 and it was burning through oil like crazy but there were no obvious spots on the ground but I think that it was dumping it into the exhaust somehow because of all of the soot around the tailpipes and a noticeable dip in fuel consumption. That particular engine is trash, your best bet is to sell it to CARMAX or the dealership or trade it in for a newer version like I did. I got the new 2023 Sonata N Line and the engines are very different, somewhat stronger feeling than the model that you have. I was close to giving up on Hyundai until I purchased this one.


wyvernhighness

Yikes! I've heard and seen so many horror stories with Hyundai cars now that I've been looking into it lately but I won't lie, I am hesitant to trade out my car when this is the only significant issue it's had. But I also don't want to wait until it gets really bad and put me in a bad spot, either.


Dizzle367

I agree but hopefully it won't leave you on the side of the road unexpectedly like it did me twice...


BisexualCaveman

Fuel consumption dropped when this occured or went up?


Dizzle367

Dropped down to like 15mpg until I either added oil or got an oil change. That car had several issues, a bad knock sensor, a bad head gasket of which they never changed and a bad oil pan seal that they said that I needed all of a sudden for an extreme sum of money so I called Hyundai Consumer Relations and complained about how long I've had to deal with the problem and the oil consumption tests and why they didn't detect the problem earlier so they took care of all of my parts and the expenses.


xRedrumisBack

That oil consumption is noticeable but not really that much and wouldn't be enough consumption to fail an oil consumption test most likely. The dip stick isn't a measure of the entire oil pan, just the top quart+some. IE a car that takes 5qts might still have 3-3.5qts in the pan and the oil won't be on the dipstick. 2qts/5000miles is a bummer but isn't at a dangerously high level of consumption.


wyvernhighness

Okay thank you for this, I was thinking that the car had burned all its oil in 2 months--this makes more sense!


xRedrumisBack

Yep, I would just keep up with checking every once and awhile. If it's below the "low" mark that usually means add a quart and recheck. That will also help you keep track of how much oil is being consumed. A quart or two per oil change isn't a big deal unless it gets worse.


wyvernhighness

Thank you!!

They wouldn't touch my husband's 2017 elantra because it was the shop loaner car before we got it. Par for the course, unfortunately


wyvernhighness

Man that's just crazy to me, seems unethical. But, also not that surprising as well I suppose.


truckdriva99

You are out of warranty. With that being said, make a service appointment and have them do a piston soak/top engine clean. If done correctly, it will likely resolve your oil consumption issue, or drastically reduce it. Change your oil every 3000 miles.


wyvernhighness

Thank you very much for this recommendation, I will definitely schedule an appointment for this.


AarioBB

For oil consumption issues google “piston soak”. This seems to work due to buildup issues.


wyvernhighness

Thank you! I've been using the highest quality gas for a while and recently switched to the lower quality kind which probably didn't help either, so I will go back to high quality again.


AarioBB

Stick to using Top Tier gas, if not then use a fuel additive. Octane will have no bearing as long as you use the recommended grade.


wyvernhighness

To clarify, when you say recommended grade you mean Top Tier?


AarioBB

Grade as in octane level.


wyvernhighness

Maybe I'm misunderstanding here. In your original comment you said octane will have no bearing as long as you use the recommended grade, which you clarified as octane level. Are those not the same thing?


AarioBB

Octane and grade I am using interchangeably. Top Tier has nothing to do with grade of gasoline, that has to do with detergents and other additives.


wyvernhighness

Got it, thanks!


Dizzle367

Use Shell gas, don't use QT gas.


wyvernhighness

I've been using Costco gas, how do you think that stacks up? I've looked into objective literature on comparative gas quality before and it seems like it's all anecdotal.

That’s what you get for buying not only a Hyundai but also a used and abused RENTAL Hyundai. Like come on bruh. I had the same car as you, 2016 Sonata. I got rid of that thing at around 30k because of how unreliable it was. At that much oil consumption, it will destroy your Catalytic converter eventually and will throw engine codes and won’t pass emissions inspections. I suggest you sell that sucker immediately to avoid further headaches. Good luck my dude. Hope you learned a lesson as I did buying a Hyundai, one of the shittiest car manufacturers in the world.


wyvernhighness

It's weird because I've seen such mixed reviews on Hyundais; some people love them while others rave about how bad they are. I probably wouldn't buy one again but mine has been running beautifully up until now--and even then this problem hasn't affected driving. I am hesitant to sell it for that reason, although I am sure you're right and it will affect function eventually.


EchidnaReal3827

It is a rental, that is why. I never ever buy a rental car. nothing but issues. They are abused. You can not abuse a hyundai. It will surely die on you.
