Honda Recall - 3.5L main bearing problems 1

[drwebb]

So Honda is having trouble with their V6 main bearings: https://www.cnn.com/2024/11/11/business/honda-engine-recall/index.html

Not a good look such a basic component has a defect coming from an OEM that leans into their engine durability prowess (or at least used to).

The only opposition is literally 'rubber belts couldn't handle oil 30 years ago, wet rubber belts can never be durable'

 

[TugboatEng]

I think the word "rubber" needs to be removed from our language. It is holding humanity back. Start calling it what it is: nitrile, neoprene, Viton, EPDM, etc...

Could you grab me that EPDM hose? I need to water the garden.

Well. look at how many recalls Ford has. Their eco-boost line of engines are garbage. GM's AFM and 6.0L, Chrysler - I means it's Chrysler. Toyota replacing 100,000 Tundra engines, Honda 3.5. Nissan CVT's.
Manufacturer's doing dumb shit like wet belts (some located at the back of the erngine) , internal water pumps.

Interesting post but not data. Makers have always had recalls - even back when the consequences of not having a recall were far less serious than now.

Cars are far more effective, complex and tightly toleranced than ever before yet reliability is (probably) higher.

I mostly agree with what you say but the current generation or engines has quite a few stinkers that may have you on pins and needles just to get to 100k miles. If you have one of the engines prone to cam failures do invest in the best synthetic oil you can get and do your oil changes at 5k and not the manufacturer interval.

There are a few engines that are prone to catastrophic failure no matter how well you treat them.

Quality and design failures happen no doubt, but I would be careful to research and understand them before making decisions. Misinformation is getting more common and realistic between AI, staged YouTube "repair" videos, and other nonsense. I've honestly started to wonder if some arent sponsored by rival OEMs rather than "influencers" doing anything for views/clicks.

Back in the so-called good old days, it was not common to get to 100k miles. It was common expectation that 75 000 was "high mileage".

There's a reason odometers didn't have the extra 100 000's digit back then ... it wasn't often needed.

Brain as old timer here I had many vehicals back in early 70 run an run, they would not die.they were simple. V8 and six engines refuse to die.. their demise was from an accident or neglect.

I think early to mid-2000's was peak reliability. Also, today's vehicles cost a fortune to fix. So many control modules in car nowadays. I think the F150 has an issue that the expensive ass LED taillight gets water inside, shorts out and takes out every module on the CANBUS.
Love the reliability of my 2004 Tundra. The engine and 4 speed automatic easily go over 500k.

Volkswagen invented the water in the harness problem quite some time ago. The pressurized coolant expansion tanks or degas tanks had a level switch. The seals would fail and the first symptom was coolant in the tail lights. It would also fill the ECM. This was in the early 2000's. Oil injection into harnesses is common as well. Some OEMs have these problems, most don't

The issue is electronics, how long does a complicated computer system last. It's a fine line.
It's cool at the biggining. But the bugs begin after time. The government is pushing to unrealistic requirements.

 

[TugboatEng]

Electronics last longer than vacuum hoses.

 

[BrianPetersen]

The nemesis of many cars of the late 1970s and into the 1980s was the "vacuum hose routing diagram". The vacuum system was basically a primitive engine computer. The car started and ran OK as long as all that was good. When vacuum hoses started leaking, or when mechanical thermostatic switching valves started acting up, or actuator diaphragms started leaking or sticking open or closed, good luck with diagnosis, because there was no hooking up a laptop and getting a "Pxxxx: coolant temperature sensor implausible range" and a live-data display to point you in the right direction.

As soon as EFI started, 90% of the vacuum hoses went away.

If my memory is correct 60, and early 70 year vehicles only had a carburetor with only a pvc valve. Late 70 and 80 emissions controls with vacuum hoses. Those were a pita. Again worked great until age, heat, carbon built up , it only effected emissions. While I agree fuel injection
With a simple module works really well and was more efficient. But so did well designed and well built after market carburetors. Holly, edelbrock and more. Simple electronic module for the distributer was bullet proof.

The revisionist history will never not make me laugh

Modern cars have problems, and the level of technology has created new systems with problems that never could have existed in previous generations. That's a fact.

But cars today are substantially more reliable and have much longer lives than cars did in the 50s/60s/70s/80s. That's also a fact. And it's demonstrably true.

If that is true I had 1983 f250 460 Cid still runs.
I had a 1953 Chevy Belair 210 2 door still runs.
I now have a 1947 cj2a , 4 cylinder hurricane engine still runs. And there are thousands of examples.

I feel like once cars moved to GDI and turbos they went down hill.

You providing examples of vehicles you own that are old and still function has literally nothing to do with statistics across hundreds of thousands of vehicles and their average lifetimes or the level of service they need to make it to 100k miles and beyond.

Your Bel Air, if it's completely unmodified with the numbers matching engine and trans, is a major outlier.

Good for you bro, never take ant thing for hear say. Always have actual justified data.

In my experience, it's the breakdown of the dash pad that determines when a vehicle is no longer worth maintaining. You have to look at it the entire time you're driving and it is extremely difficult to source once obsolete.
