Where did the ceramic part go? Did that come out of the engine like that?

 

When the shop pulled the plug out, the ceramic was gone.

 

I would borescope in the cylinder to see if the cylinder walls were damaged as the ceramic was being destroyed and exhausted out of there.

I'd also do a compression and leakdown test on at least that cylinder + others for comparison, to see if valve sealing was affected.

And I'd replace all the other spark plugs.

But that's what I'd do on my own car at my expense, doing it myself. Whether those things are justifiable or reasonable per the terms of your warranty is a different story. If they won't cover those tests, but will cover repairs if needed, you may want to pay to get them done.

 

Copy that...the first shop I went to was familiar with the 2011-2013 recall and assumed my Ody was part of the same cohort, but it’s not. I’m waiting to get feedback from Honda who said they would probably not get to it until first thing tomorrow. Unfortunately, this is my family hauler and I have 4 little ones...so this puts us in a major bind!

Am I the first person to experience this with a greater than 2013 Odyssey? My dealership cannot give me an answer as to why this happened, and for now they cannot explain why or why not this is covered under the Powertrain Warranty, which is good until 60k miles or 5 years. I'm still waiting to see if they can give me a definitive answer about the warranty, since my Service Advisor started to stumble over his words when I questioned this last part.

I should mention that the Service Advisor described following all of the steps as described in the 2011-2013 Odyssey Service Bulletin 13-081 to the letter about how they would approach addressing my Ody with the repair.

No, you are not the first. I’ve seen others with Odyssey’s newer than 2013 that were just out of warranty, but thankfully Honda was doing good will coverage of like 90% cost of repair.

There’s no reason your Odyssey shouldn’t be covered 100% under warranty if the fix described matches the 2011-2013 warranty extension.

 

I have a 2015 Odyssey EX-L like you. I had the issue around 54K about 1.5 - 2 months ago. Same cylinder. My spark plug was caked in oil as well. They said my misfire was due to cracked ceramic on the spark plug. I asked my brother if he had ever seen a cracked NGK spark plug. He stated, only if someone dropped it. I can't prove nor suggest that it was dropped to prevent them from fixing anything. They replaced that plug, I replaced the others and put an S-VCM on my van. Crossing my fingers everything will be ok.

 

After a lot of back and forth and discussions about the Powertrain warranty and my CarMax MaxCare extended warranty, I wound up having to cover the cost of new plugs for the rear bank of cylinders and oil/filter change, because Honda finally stepped up and covered the cost of the repair under the Powertrain warranty. The initial quote was 35 hours of labor and no discussion about how much the cost of parts would be. They did the work as described similar to the old service bulletin with cleaning the pistons and replacing the piston rings in the rear cylinder bank only, since the only affected cylinder was in that bank. We have had the Ody back for a week, and so far so good with a healthy dose of paranoia.

 

Thanks for the update, keep an close eye on it as I would think Honda owns this repair! But that all sounds like steps in the right direction...

 

35 hours of labor????

 

That's what they quoted me that got me worked up about the cost of the entire repair. The service bulletin I mentioned puts the Procedure B repair for piston rings at only a flat rate time of 8.5 hours, but I'm not sure if that was a real estimate or not.

 

I need to get in touch with my dealer again today, since I discovered the Ody is leaking oil in the garage.

 

The dealer has had the Ody for two days now, and they thought it was just the valve covers that needed to be replaced. They claimed to have looked over everything and replaced the valve covers. However, there is still an oil leak. They speculate there might be a hairline fracture, but it was not clear where the hairline fracture is located. I'm hoping not in the block somewhere. They're going to continue to hold onto the Ody in the meantime while they get us a "loaner" so we can head into the long weekend with something to get by. There was no oil leak prior to the work they performed at the start of this repair.

 

Got the Ody back just in time for 4th of July road trip, and the small residual oil slick in my garage the day we left was probably what they didn't clean off from the previous day's work. The paperwork we received later as they shoved my wife out the door with little explanation stated that both valve covers had to be retightened and that one of the valve covers developed a hairline fracture that required it to be replaced. They redid both valve cover gaskets as well. I am going to be keeping my eye on this repair job closely as the work is not infallible.

 

May I ask what they ended up charging you in total?

 

For everything that has happened, I only covered the cost of the oil change and plugs at $167 during the initial repair. I did have to pay a $50 diagnostic fee when I took the Ody to a CarMax affiliate prior to my dealer when the problem first happened, and fortunately, my AAA membership covered the cost of towing the Ody from that shop to the dealer when I was told that I should not drive it further by the original shop (it was in limp mode anyways).

 

Not bad considering the work that was ultimately done to get you back up and running.

 

Why does anyone care if it were 35 hours or 135 hours considering the problem was covered under the extended power train warranty?
