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).

A minor issue on a few years of one variant, of one engine, in one of the most-produced engine families, known for reliability in everything from 3rd world cheapies to 1st world supercars.

Not true at all.Timing chains and phasers. Watch Ford Tech Makuloco's videos.

The problem here is that many are relating their experiences with NBR or EPDM rubber to HNBR rubber which is quite a bit more durable under hot engine conditions. You can't blame the rubber for incorrect specification.

As for engine room fires, lube oil and diesel fuel both have lower auto-ignition temperatures than gasoline. Fires do happen. I've had one. It was a lube oil fire that ignited when a steel line broke.

I imagine whoever designed the belt (Gates maybe) is well versed in hot versus warm conditions. Seems like it is more not finding a mix that will tolerate all the chemicals in used engine oil for that amount of time/miles. Although, Honda has been using wet belts in their small equipment engines for decades - which notoriously have dirty oil.. Have not heard many issues with them although the consequences of a broken belt in that application is not much.

Warranty data proves their reliability, hence the reason they've been one of the top-selling engines for 15 years.

As mentioned previously, most of the top "influencers" on YouTube famously fake their videos for views and either mislead or blatantly lie about having professional experience. Their "barn finds" and "cold starts" arent, "restorations" often involve faux-rust applied to a restored car/gun/toy/etc, and "tear-downs" involve staged parts. Its entertainment like "reality tv," not a documentary., and often scripted by sponsors. Believing that nonsense is like believing the Instagram girls' 44ZZ-14-44 figures aren't AI-enhanced.

I am guessing you are a Ford Truck owner. Anything can make it past a 60k warranty. These things don't start failing until they are out of warranty.
They are likely top selling because people buy them based on Fords' past history of having reasonably reliable stuff and huge brand loyalty . I guarantee you that is changing.
