2018 Honda Accord 1.5T engine failure

Hello everyone first post here although I’ve been reading the forum a while. Like the title says on April 24th my wife went to start the accord to drive home from work and it would not start. Got the vehicle towed to the dealer and it turned out to be a bent piston rod. Been driving a rental covered by warranty since. They claim that they are waiting for a head gasket and it is on backorder. Very frustrating it’s been at the shop for 5 weeks now. The car was 8 months old with only 12000km all required maintenance was done by the dealer. Does anybody else have similar issues?

Wow. Did they explain how that could have happened? Do they have any idea how much longer to get the gasket in? I think I'd call Honda and suggest they have the engine plant overnight a gasket and build one less engine tomorrow. I'm sure it wouldn't work but I'd have to do it anyway. Good luck.
Forget the gasket, I'd want a new engine. Did they perform a oil analysis to determine if they have fuel in the oil 8K miles is low for an engine to fail. Personally, I believe that 3.5 quarts of oil in a 1.5L engine with a turbo is not providing enough lubrication or cooling. The 2.0L is a much better IMO and holds 5 quarts and and special valves to dissapate the heat. We already know that antifreeze got into the oil, not a good thing.

I argued for a whole new engine but they are replacing the short block and they apparently sent the head to some lab for analysis(pressure test he said) and say it’s good.
So they're not going to replace the head? I used to have alot of confidence in Honda, but after a recent discussion with a local dealership they would not admit they have a problem with CMBS. I just wanted to know if the latest TSB solved the problem and they were adamant that they don't have a problem. This issues is widely documented and I even sent an email to corporate and all they told me is take my car to the car to the dealership even though I don't have a car and was just checking if the issue had been solved. So neither the dealership or corporate won't admit to a problem that is general knowledge to just about everyone else.
Correction:It was a bent connecting rod. Sorry my bad.
Piston rod and connecting rod are the same. Connects the piston to the crank. Good luck, hope everything goes well!
It's been documented previously (and a couple threads on this site) that there is a problem w/the 1.5 Turbo in the Civics and CR-V's. This article - Honda's Popular Turbo Engine Is Causing Problems showed up on my news feed yesterday. I have yet had someone explain to me why the 1.5 Accords aren't included in this issue, and/or what is the difference between the 1.5 motors in the Civic/CR-V's and the Accord.

Since Jeff reported the mileage in kilometers, he's probably from Canada. The fuel/oil dilution could have occurred during the Winter months and the consequences just appeared now.

Regardless of whatever they do, you should request an extended warranty given the work that they’re doing.
Wow. I guess this is where I mention that maybe getting a Blackstone report with each oil change would be a good idea. I think I'll be doing that now for early warning.

I did Blackstone reports on my 2014 Accord and got to be a bit lazy about changing the oil every 6 months because the oil was doing great after 9 months and even more. But with this known issue out there it seems like a rigorous 2x a year old change + Blackstone report would be a very good idea.

Looks like Accord engine is in fact CR-V engine (see bolded test)

"The CR-V offers a 2.4-liter naturally aspirated inline-four that makes 184 hp and a 1.5-liter turbocharged four that makes 190 hp. But because the base LX trim is the only version that uses the 184-hp engine, we wouldn't say the CR-V offers much of a choice. The Accord, meanwhile, uses a 192-hp version of the CR-V's 1.5-liter turbo. "

Car Compare: 2018 Honda Accord and 2018 Honda CR-V
From Autotrader:

"However, things get even better with the Civic EX-T and Touring, which have a 1.5-liter turbocharged 4-cylinder that produces 174 hp and 162 lb-ft of torque. Not only does this engine yield some of the strongest acceleration in its segment, but fuel economy actually goes up to 36 mpg combined with the CVT. It's also available with a 6-speed manual transmission, but if you're game for changing your gears, the manual-only Civic Si sedan offers a 205-hp version of the same engine without a substantial fuel economy penalty.

The Accord has the same basic 1.5-liter engine, but it's retuned to produce 192 hp and 192 lb-ft of torque. That, too, is one of the strongest outputs in the segment, and its fuel economy follows suit with an exceptional estimate of 33 mpg combined when paired to the CVT. Should you want more power, the Accord is available with a 2.0-liter turbocharged 4-cylinder that produces 252 hp and 273 lb-ft, and returns 27 mpg combined with its standard 10-speed automatic transmission. A 6-speed manual transmission is available on the Sport trim with either engine."

I will say that the acceleration on my 2019 LX Accord CVT seems to blow away my 2014 air breathing 6 speed manual (R.I.P.). And that was without the S engaged.

I'm afraid I don't have numbers for 0 to 60 manual vs CVT. Does anyone?

It's just that I do a left turn onto a major four line highway and hard acceleration is often needed. In the old Accord I would take it up high in 1st and then high in 2nd before shifting directly into fourth or fifth gear at around 45 mph. When I punched the CVT I seemed to be pushed back into the seat a bit more. It wasn't like I was holding back with the old one. The 2014 had 185 horses, no turbo, no CVT.

Anyhow the sum of it is that one buys an Accord so as not to sweat stuff like gasoline getting into the oil. If this is a big issue it's sort of like, why the **** are we buying these cars.

And there's this article which says that there is a gasoline in oil issue with 2017 and 2018 and that there might be a recall. The article also says that for 2019 the issue is being addressed in the factory.

I must say the dealership is taking care of me the rental car is being covered. Talked to the technician himself and says parts are taking a long time to get to them from Honda. I was a bit frustrated when I first posted. I will come back with an update later.

So WHat did they say ?

Piston rod and connecting rod are the same. Connects the piston to the crank. Good luck, hope everything goes well!

What Bent Freaking Rod ?




I'll Guess Either to Lean Fuel Mix , or to much Fuel in Oil ~ or Bad Injector ~ what Minds need to Know ~ Did You have it Documented Before Hand ( Any Issues ? what so ever ? )

Did You have Stored Codes of any Type ? Before or After ?


Please get Codes from Honda's Tech ?


Did You see the Connecting Rod ?


Please Note If there are ~ Injectors being Replaced as Compared to Stock OE Units came with Your Vehicle ?



Take some Picture of this Work or it didn't Happen ~ Besides ~ You need to keep Tabs on this - Like Lets see How they are Dropping the Engine Out !

Do Honda Tech's have an Engine Jig that Mounts everything in Correct Spot ( Hello ) ! ( Many Dealers ) Don't Pop for the Real Tools ~ :nerd: ~ OMG You Mean to say

They could be Screwing it Up - Oh Yeah !

Was a reason for them needing replacement given?
Every light on the display came on but the car was running and did not feel any different. I was on a 100-mile trip and was able to continue. This was to the town I purchased the car in. Dealer had it for 5 days. Said the 3rd cylinder injectors was bad. They replaced all four. No explanation or specific problem was given when I asked. The said sometimes it just happens.
