This is the first I've learned of this, and of course, after I just bought a 2024 Ridgeline with 10K on the clock. 🤷

Anyone have any knowledge or experience of these Honda V6 issues in the Second Gen Honda Ridgeline?

Honda recalled 249K vehicles for possible rod bearing failures. The NHTSA received complaints of failures outside of the recalled population so the agency launched an investigation in November of 2024.
MYs 2016 - 2020 are under investigation and include Honda and Acura models with the J35 V6. The RL MYs are 2017-2019.

And the inspection/repair:




Rest easy - as others have noted, 2024 is not affected by this recall.
Well not yet, but that is no surprise. The later model Ridgelines may or may not end up being recalled. Much more often than not, it takes 3 or 4 years minimum for these sorts of problems to be fully revealed, and then to have enough failure instances that a recall eventually is forced on the manufacturer. For obvious reasons, auto manufacturers do NOT want to do major recalls -- it costs them a lot of money, and their reputation suffers.

Case in point -- the Toyota Tundra redesign -- 2022 to present. These trucks are blowing engines right and left. The 2022 and 2023 were finally recalled. Blown engines on warranty initially were being replaced with short blocks -- lots of labor for the Toyota techs. But now they are replacing them with long blocks.

The 2024 Tundras and even some 2025's have also started blowing engines, but the recall has not yet been expanded to 2024-25. Clearly Toyota has not solved the problem. I expect the newer ones will eventually be added to the recall, but that will take some time.

Similarly, it will take a few years to see if any of the later model Ridgelines end up with the same V6 issues. The jury is out and will be out for a while.

My 2017 RTLE is also approaching 100k - I'm likely to hit that threshold by the end of May or June. A VIN search on the NHTSA site for mine turns up nothing, except the recall for the tonneau cover (which I have never had installed).

The NHTSA Safety Recall Report 23V-751 says "Owner notification is scheduled to begin and end on or about 1/2/2024." Does that mean mine is not affected???

V6s for the RL are assembled at the Alabama plant. The ZF-9 AT is assembled in SC by ZF. At some point Honda transitioned V6 production from the Anna, OH engine plant to Alabama so the recall population may have been assembled in OH.

It would seem that not all of the vehicles built within those date ranges are included in the recall. My 2018 doesn't show up in the NHTSA search either.

When I saw that GM was recommending a thicker oil for their 6.2L V8, I started thinking about how our Honda’s use 0w-20, and wondered if they might end up recommending a similar situation down the road. 5w-30 has always appeared to be a well proven weight in Motor oil.

Mine RL has a build date of Jan 2020, so for now I’m good, but who knows later on?

In terms of oil, I use Mobil 1 0w-20 Truck & SUV, and thus far haven’t had issues with 67k miles on it (got it with 23k miles on the odo).

It is possible that that could happen, but it is also important to remember that if an engine won't benefit from 0w40, then you won't see any difference, other than slightly decreased MPG.

IOW, don't just throw 0w40 in your Honda thinking it will prevent issues, or that it will protect the engine better. If you ran your engine at 6500rpm all day long in 90+ temps, then the 40w would help, but how often do you do that?

In the case of the 6.2L, the engine bearings are wearing in such a way and under such conditions that the 40w will protect those bearings better under extreme stress. In simplified terms, GM will check the alignment of the crank, and if it doesn't meet spec, you will get a new short block. If it does meet spec, they will recommend the 0w40.

I thought GM is only addressing unsold vehicles.

For Honda, we still don't read about engine failures at high levels and it seems like some aren't covered anyway, outside the population. Meanwhile, Honda continues to run out the clock. Still no answers as to how many engines have been replaced and if the failed engines that were eligible for repairs/replacement had the knock that IMO all of these engines have. The media isn't much help either, they just throw out large numbers for a headline but buried in the story is that a tiny fraction of the population to be checked will receive a fix. Does this mean you own a ticking time bomb and once out of warranty you're SOL or is it a low impact liability to Honda and Honda owners. I don't think we will ever know unless the government isn't satisfied with Honda's plan. IMO this one is a yawner but how Honda deals with it creates the interest.

GenI Ridgeline has been around since 2006 (2005 actually) and was originally specced with 5-20 oil and later shifted to 0-20 (which was subsequently approved for use in all years of the GenI) There has been NO notable indication of lubrication based failures over millions of miles driven in thousands of vehicles. I doubt very seriously that the oil weight is the underlying cause for 2nd Gen bearing failures. Could a heavier weight oil help the problem limp along a bit longer? Who knows? . . .Maybe or maybe not, but again it's not likely the root cause of the issue but rather a manufacturing problem.

Just a reminder that the engine failures that triggered the recall were caused by out of tolerance crankshaft connecting rod bearings. The problem was caused by improper machine configuration during crankshaft manufacturing. That's according to Honda anyway. My memory is fuzzy on this, but I think they might have tracked the problem down to one particular parts supplier.

So the recall is about a manufacturing issue that affected a small number of engines that were built with crankshafts that might be out of spec,and among the vehicles recalled less than one percent were expected to actually require repair. Again, that's according to Honda. The recall had nothing to do with a design issue or poor lubrication.

The current investigation of engine failures on vehicles that weren't in the recall is just that - an investigation. There isn't enough information available publicly to know if it's the same problem as the recall, a different manufacturing problem, a design problem, or maybe even not a problem at all (i.e. the number of failed engines might be within the normal range).

Yes, well our 2017 Ridgeline had the exact same problem, the exact same issues, and Honda kept our truck for over a month after I filed a complaint - and after a month they declined to do anything at all. They wanted $12000 for a used engine replacement. We are having our mechanic see if he can just replace the rod bearings instead. Horrible service.

Suddenly all the lights came on and it was making a loud noise, the same thing that the other cars incuded in the recall had. And both our mechanic (who used to work for Honda) knew right away what it was, and so we had it towed to the Honda dealer who told us the same thing, the connecting rod bearings, and wanted to charge us $12,000 to replace the engine with a used one - just because ours was not included in the service recall. AND it took them over a month to let us know that they would not cover it after I initiated a complaint and had a case number. Seems like they could have let us know that in the first week instead of keeping our truck for over a month.
