So my wife's 2015 kia started consuming oil a while back. It had around 115,000 miles when it start. The catalytic converter clogged up right before that and I didn't know about the excessive oil consumption issues these engines have at the time.

So now it's consuming about 1 quart every 500 miles or so and has 126k miles on it. And just the other day it started misfiring at throughing the 02 bank 1 sensor 1 code.

After restarting it, it ran smooth for a few days, but now it's started again.

My guess is the excess oil being burned is fouling up the exhaust and the O2 sensor.

I sent her to pick up a new O2 sensor to try, but what I really need is the engine replaced.

It has a PI2002 engine warranty extension to 150k for rod bearings knocking that some ECU update was supposed to solve.

The dealership says that doesn't cover the oil consumption, but they act like if I just intentionally blow the engine up by driving it hard etc (as long as I have maintenance records) the warranty extension would cover it.

Any thoughts or suggestions? I'm all for tearing up the engine, but how do I know for sure they would actually honor what they say in that case?

Thanks for any advice.

Another poster sometime back wrote of being told the same or similar by a dealership. I looked but didn't find the post.

If you drove it hard, would the engine actually "cooperate" and throw the required rod (for engine replacement), or might it fail for some other reason. And should it fail, might it do so at a very inopportune / potentially dangerous time.

Additionally I don't think there would be any way to know for sure a replacement engine would be approved until it actually is approved.

Maybe try a different dealer to see what they say???

Yeah, that was my thoughts. What guarantee do I have.

I've got it at a regular mechanic today. The O2 sensor my wife picked up was the wrong one, even though it said it was compatible the connector was wrong. Going to see what the mechanic comes back with.

Thanks

Don’t go blowing up your engine unless you have in writing that the dealer said they will replace it, because otherwise they’re going to play dumb and say it blew up because you didn’t check your oil and you let it run dry and then deny your claim.

Try another dealer and in the meantime search for “piston soak” and try that to help with the consumption. The new cat🐱 wont last long if it’s been burning that much oil.

Well, got an update from the mechanic. Cylinder 3 is full of oil. Surprise surprise. Worthless engine. 126k and all maintenance performed as required. Supposed to go talk to him tomorrow about some options.

Well the mechanic gave me some suggestions...

I'll come back and follow up with how they worked out in a week or so.

What were the suggestions?

There are other threads about Gen 2 oil consumption that you can refer to for detailed information. My nutshell response to this one is that if I were in your situation, and if the problem were just deposits and not mechanical damage, I'd do the following:

1. Ask the dealership how much it would cost to do the piston soak not under warranty. If they gave me what I thought was a reasonable answer, I'd have them do it. If not, I'd do it myself.
2. Same for an intake system cleaning, which incidentally cleans the rings somewhat.
3. Use a high-quality high-mileage oil if I weren't already using one.The extra detergents seem to be rectifying a much less severe oil-burning problem in my 2016 on their own. (I'm using Castrol Edge High Mileage oil, but there are others.)

With that much oil loss, however, there's a fairly high chance that the problem is mechanical damage (such as worn or broken rings, scored cylinder, or both). Nothing in a bottle or can will help that.
