So here's my story. I have a 2018 2.0 Auto. (25k miles) I got the Ktunerv2 from a member earlier this week. Flashed the car to the stage 2 dual tune. Drove around 400 miles with this tune. No problems,.

Then today the crazy thing happened. I was driving home from work and decided to pass a slower car. So I went from eco into sport mode and passed the car. Was going about 75mph. I notice the car did not shift. When I pressed the gas pedal, it down shifted as expected and took off maybe shifted once and went all the way to around 5600k rims. I let off the gas and used the paddle shifters to shift, went through all the gears just fine. So, I drove about another 5 miles, hit the exit ramp and all of a sudden lose all power while waiting at a red-light. Car shifts its self into park. I try to restart the car but the engine won't turnover. I had no CEls pop up and no errors show in the ktuner log either. I dont know if it was the tune that caused this, if my transmission messed up, or if my fuel pump just kicked the bucket. I flashed it back to factory,(not that it will matter) and got it towed back to the dealer.

Anyone want to offer their thoughts on what the issue could be?.

Can't really tell without the codes but could be a boost hose slipped off
Dealer ship called the other day. The turbo malfunctioned, and peices of the turbine broke off in the intake. Highly doubt their going to fix it. Their waiting on word from Honda. Seen a post about a turbo malfunction before from a user that didn't even tune his car. And he was told they were not repairing the turbo. Fingers crossed.

Don't see why they wouldn't replace a stock vehicle. So you need engines work to then,that sucks.

Unfortunately it wasn't/isn't no longer stock as it had KTuner installed running stage 2 dual tune.

@BMF Twitch keep us posted.

This was my first thought. He modified the car then was surprised when something went wrong. There's always a risk of failure or damage when modifying a stock car.

Unapproved Honda modifications and accessories violate the warranty. Even a Honda approved accessory violates the warranty if not installed by a certified dealer. So, I don't see Honda accepting responsibility for the repair.

I worded that unclear. I was referring to the stock vehicle he mentioned.
Ok, gotcha... you were speaking of this vehicle..

I would agree w/you in that particular case... If it was still running factory specs and still under warranty it should have been a warranty repair/replacement. (y)

Most definitely a risk when one goes to high performance accessories... sometimes you can get by... sometimes you don't... you have to pay to play.

There would need to be Something Wrong with Turbo ,

Even If Tune Held Waste Gate so it didn't Open as much - sure seems ~ Story is Bit Off ~ Lets say it went to
26 PSI - that may have spun Turbo extra 12000 Rpm so it Hit 130,000 Rpm instead of 118,000 that should Not Blow Up Turbo ..

These Tunes - should No Way in **** be Blowing up Motors Or Turbo's

U Guys Better start Paint marking Hidden Dab of Paint & Scratching Parts to make sure Those are Your Parts . .

Means Inducer Blade Blew Up - with Only 2 X Engineering in Play CHRA should be able to do 160,000 Rpm - just Seems Odd !

Shock Waves coming from Electronic waste-gate ? Still seems something a Mist - Poor Turbo Impellers ?

I have all Pieces Collected - Take these Pieces of Turbo & What's Left of Inducer Blade : To ~ Machine House for 50x Inspection -
Look for Porosity Inside Turbo Compressor's Inducer Blade **

I can only tell you as much as I know. The dealership was the ones that said the turbo malfunctioned. When the incident took place. The car was whisper quiet like usual. Nothing sounded abnormal.

Maybe I just had a bad turbo?. I'm thinking whatever caused this to happen was going to happen, regardless of the tune or whether the car was left stock.

If I hear any updates I'll let you know.

Very interested in what the dealer responds with. I do agree that the tune should not have caused the turbo issue.

Yea, that call was great news. The dealer mechanic thinks that turbo was faulty to begin with. He said he's seen issues with the accord but first time seeing a turbo problem with the platform.

Did mechanic mention what issues he's seen?
