Honda turbo engines are bad - close to recall

[Omegaboost]

This is caused by the use of ultra low tension piston rings that allow too much blowby. Honda really screwed up, only way to fix it is by tearing apart the engine & replacing the rings.

Well, looks like they'll be some good contract repair work at Honda in the near future... that's a pretty big oversight.

Honda piston rings again?
Feels like it was just yesterday folks were talking about Honda piston rings

[Hail The Brain Slug]

As far as I can piece together, the problem is most prevalent when you idle for an extended period upon cold start in very cold weather. It's compounded by not driving long enough to heat the engine oil to operating temp and evaporate the fuel back out.

I picked up a 2018 Civic Si a few weeks ago and I've been watching my oil level like a hawk. So far, no problems. I don't let it idle more than the 30-45 seconds it takes to drop below 1200 RPM, though, and it warms up really quickly once I start driving.

Supposedly the ECU update to fix it makes the engine warm up more quickly during cold start/idle to minimize the time fuel can blowby into the crank case.

I'm not too worried in my case, I don't have an environment or driving habits conducive to the issue. A simple change in driving habits might solve it for others, such as minimizing cold start idle and going for trips long enough to fully heat the oil and evaporate contaminants on a regular basis. I've always done that with my vehicles, anyway, after having a 92' Jeep Cherokee that was never warmed up causing oil to cake onto everything due to condensation.

I read about this. Honda issued the recall for the CRVs with the affected engine. If they find that they indeed are suffering from a loss in horsepower, Honda engineering has agreed to retrofit the affected CRVs with complimentary NOS sticker, to be placed on the backglass. This is supposed to boost performance on the I4 turbocharged engines by 40%.

Had to get that done on my 2012 Odyssey. At least Honda covered it.
This might shatter the "Honda and Toyota are most reliable" for my wife. Finally.

"Skittish."

Some of their variable displacement engines (cylinder deactivation, from like 2008-2012-ish) burned craptons of oil, and the first 8-speed or 9-speed transmissions from like 2014-ish were problematic. (The newer 10-speeds are apparently pretty solid though.)

Never buy version 1.0 of anything, I guess.

I have a 2009 odyssey with the intelligent Vtec V6 with cylinder deactivation. It definitely uses oil. still has gone 154k+ miles with no real drivetrain issues (o2 sensor and a high pressure power steering line). It uses about a quart and a half between changes (a qt every 4-5k miles).

I have recently been researching a replacement sedan for my mother in law. the new accord is a strong front runner. they offer this in the 1.5 turbo, and the motor isn't what I would shy away from. I'm not sure Id want the CVT. She had a 2006 altima with the CVT and she says she likes it; and fingers crossed hasn't had a single issue with it. I am going to try to talk her into a 2.0t sport with the 10spd. I'll disguise the suggestion with the fact she gets the heated side mirrors and the sport seats bolstered in leather with clothe centers

I think CVTs fell into the "never buy v1.0" trap about 10-15 years ago, but they're apparently much better now, so I probably wouldn't let that put me off of a car.

Heck, remember back in 2007, gas was $4/gal and people (including my dad) were paying crazy dealer markups for second-gen Priuses? IIRC, those had some kind of CVTs, and they ended up being some of the most reliable cars, like, ever. (My dad's is pushing 400k miles.)

Yeah, I'm not a big fan of the turbo 4s either but I ended up with one because that's what everyone seems to be doing in this class. The mileage savings are honestly negligible, and in practice I think all of these changes for a few extra mpgs are actually causing more harm in practice. I also don't like 8 speed transmissions... I have yet to find a good one, yet that's what the market is doing if they're not already using CVTs. They're often tuned so heavily towards fuel savings that I have to accelerate harder to get the transmission into a lower gear in order to get moving the way I want. I didn't have to do this with other transmissions, and I'm sure I'm completely negating positive effects the transmission has on mileage by driving the way I do to overcome the terrible shift points.

The 8 speeds and turbo 4s just reek of things done to get the numbers to look better, even if in actual use nothing has changed (and maybe is even worse).

put it in S gear, for sport? turn off the eco button? i was pretty upset to see that accord went to 4 with turbo i get over 40 mpg with a 4 cylinder 2016 accord at 75mph.

Oh and for some reason the California DMV wont give me my registration until i take my 16 accord for a transmission computer update for some reason its required recall. Super annoying since they want me to leave the car for a few hours and im always busy or gone.

what scares me is that they are "sealed" units. not meant to be serviced or repaired.

 

[NutBucket]

Eh, most transmissions are considered "sealed units" these days.

The Subaru dealer is more than willing to change the CVT fluid even though it's supposedly a lifetime fluid. Which reminds me I need to get that done.

What Nutbucket said. The "sealed" units don't have dipsticks, but they still have drain and fill plugs, and it does seem to help them last longer if you replace the fluids now and then.

They're "lifetime" from the perspective of the manufacturer, and from the standpoint of the customer if you never keep a car past 100k.

exactly...

100k miles on a car these days is nothing.
