My women drives a 18 corolla she had the same issue. She couldnt pay for registration online or in person without going to the dealership and getting a emissions update and certiticate.


I own a 2018 Civic Si. I did NOT get this notice. You made me panic though. So i just paid for my registration online. And it went through....

I also bought my 18 civic Si brand new. When 2019 were coming out. If that matters.

Should be the oil dilution update. You'll want to flash your car back to stock before bringing it in. I'm glad they decided to start rolling it out to Californians.

I suspected it’s the oil dilution thing, I’m in Ohio, I’m not getting any MIL lights I’m just wondering if the dealership is gonna flash the ECU and then afterwards I flash it with Ktuner, will I have basically undone the fix that the dealership did? If it is in fact what the dealership is gonna do?

The TSB started rolling out a while ago. Contact JR @KTuner , my understanding is they've worked the oil dilution fix into the current basemaps for most (all??) ECUs.

So far I did not get the notice, I was able to renew my registration online with no issues. I bought my Si in June of 2018, so possibly this issue was fixed

EDIT

I live in California, I don't think this issue affects us as most people who received this are in states with colder winter climates

Ok so sounds like nobody on the forum has received this letter or knows for sure what it’s about specifically? And if it’s a reflash whether Ktuner has put these settings on there maps? I guess I’ll go surfing the web thanks for the replies.

If you search “oil dilution” a lot of threads have been talking about receiving letters. I was reading a thread yesterday that ktuner claims to have reflash update included in new basemaps after TSB performed if you have an si. Base models are apparently still waiting.

Thanks yes I searched around and it’s the oil dilution problem and yes it appears that Ktuner has incorporated the Honda fixes into their tunes, at least that’s what I read on a few of the posts. Question I will flash the vehicle back to stock tune before bringing to the dealer, but also what is this “unlock” procedure I’m reading about for Ktuner? Thanks.

I don’t personally own ktuner yet. I’ve read other posts from owners that say ktuner can only be registered (I.e. locked) to one ecu at a time. I’m sure ktuner support page can show you how to unregistere yours before going to dealership.

i got the same mail today, I have a 2019 civic sedan 2.0L. So far nothing has popped up on the dash. Should i still bring it to attention at the dealership?

I have decided not to do the recall. I haven’t had issues and I’ve been running the tsp tune for some time now.
