2017 Hyundai Sonata Theta II Engine Problem, What Now?

After doing some research and talking with both my Hyundai dealership and a corporate case manager, I’m pretty sure I’m out of luck, but I’m hoping for some advice:

I’ve got a 2017 Hyundai Sonata with 72k miles. I bought it used with 12k miles, and it’s run fine for the last 4 years.

Earlier this year, I noticed it was burning oil heavily, so I did some research and learned about the Theta II engine problems. By that point, I was already past the 5-year/60k mile warranty that would’ve covered it. After talking with a tech at the dealership, I just kept adding oil and driving it, hoping for the best.

Fast forward to a few weeks ago, the engine started chugging, and the check engine light came on. The dealership said the engine needs to be replaced, but the issue isn’t related to rod-bearing failure—it’s due to cylinder wall scoring. They also mentioned that even if a rod-bearing failure happens later, Hyundai still might not replace the engine due to the current damage.

So now I’ve got a car that still drives but with the check engine light on. I have all the records for regular oil changes and maintenance. I just didn’t know about the engine issues when they first started. Any advice on what I should do now?

I’m in the same boat with the same car. I just crossed 65k miles. I’m about $7k upside down because of theft and vandalism, plus the Theta II issues. I’d trade the car in right away if I could break even. I’m just hoping that if my engine fails, Hyundai will replace it. If not, I’m not paying for a new engine. I’d rather walk away from the car and put my money into something else.

It’s a bad situation for sure, and it feels like we’re stuck hoping Hyundai steps up. Maybe car insurance could help? I’ve seen cases where insurance covered engine failures, but I’m not sure how that works. I hope things work out for you, and just know you’re not alone. Hyundai should be paying for these problems, not us.

Unfortunately, car insurance doesn’t cover mechanical failures. They cover stuff like accidents, animal strikes, or theft, but not engine problems. That’s where the manufacturer’s warranty, extended warranty, or third-party warranty comes in. In this case, since the warranty is up and it’s not a rod-bearing issue, it looks like OP is out of luck.

It wouldn’t hurt to ask the dealership to submit a goodwill claim to Hyundai, but it’s a long shot. These engines are known to have issues, and it’s sad to see. I’ve said it before, and I’ll say it again—never buying a Hyundai again.

You won’t get any disagreement from me! :raised_hands:

This is a link to the settlement notice. Not a download, just a PDF.

@Atkinston
Thanks! I looked into it, but I don’t think I qualify. The closest part of the settlement seems to be reimbursement for costs due to engine stalling, knocking, or engine failure. But since I haven’t done any repairs yet, I don’t have any expenses to claim. I’m not sure what to do at this point without knowing if the repairs will even be covered.

@Zack
There are two parts to the settlement—reimbursement and engine replacement. You should keep researching your options. Check out this article for more info: https://www.classaction.org/blog/new-hyundai-kia-engine-failure-settlement-covers-2m-additional-vehicles.

@Atkinston
Did you even read OP’s post? His issue is excessive oil consumption, not the rod-bearing failure. These are two separate issues. The class-action only covers rod-bearing failures.

OP: Sadly, I think you’re right—you’re probably out of luck.

@Dany
Actually, worn bearings can cause oil consumption problems. They are linked.

No, they’re not related. These are two different problems.

You clearly don’t know much about engines. Worn bearings can cause excessive oil consumption, and it’s part of what’s discussed in the class-action. Here’s a more detailed breakdown if you’re interested in learning more.

@Atkinston
I know quite a bit about the Theta II engine issues, and I can tell you the rod-bearing failures and oil consumption are two different problems. The bearing failure happens quickly due to oil starvation, not because of excessive oil consumption over time.

@Dany
You’re wrong, and here’s why. Worn bearings can indeed lead to excessive oil consumption. You should read up more before making claims.

You’re entitled to your opinion, but you’re still incorrect. Stop spreading misinformation about this issue.

This comment doesn’t seem to make sense, admin should fix it.
