Does there seem to be a trend of which serial no. batteries are cracking? Or is it just random? Do the serial no's go in order of build date for example 0001 oldest 0004 newest?
Good question. Canyon knows this, the public "us" has not stated any of that yet. What I have seen is this issue started in Germany early spring so I have a feeling since there is such a large recall, that you will find different dates for bad batches of batteries. In china they probably got the plastic to hot off and on, which could be seasonal issues in china weather related. Over cooked plastic gets brittle once molded. OR just substandard plastic to begin with. Chinas quality control and greed is what bit Shimano- Canyon- us. People that blame on the engineers are clueless. American parts fail let alone the Chinese parts where they cut every corner they can.

to suppose the root cause here is a sub standard plastic used to form the casing is pretty naive.
If you have no education, or are not a mechanic, ignorance is bliss. The mounting location is the weak link, so its generally where you will see failure first, if the plastic is "substandard". Which you cannot even spell right. If it was engineering and not the plastic Einstein, we all would have failures. Not a very small percentage of the bikes sold. Why is my battery fine with more miles and speed then most here? because it is not the engineering. Fact is, and what we see is plastic failure. Like it or not, the plastic is failing regardless of why. So if we use our fkn brains its pretty easy to deduce plausibility. One of two things is causing the plastic to fail. Substandard plastic, or faulty engineering. #1 china produces the plastic. Enough said? #2 the plastic is also breaking in places away and remote from the mounting locations indicating bad plastic. #3 only a small number of units are affected. If this was an engineering problem, more units would be affected, and the breaks would for the most part, only exist in the mounting locations. And those who ride harder, would experience the majority of failures #4 the units failed, show signs of weak plastic. #5 Failures in the plastic with 47 miles is factually due to weak plastic.

the fact the same factory would have used exactly the same plastic for thousands of its other battery products, it is just not feasible.
Nothing is "fact"" you said. It could be the same plastic, but temperature fluctuations could cause some to be brittle.

Understood. That is the vast minority of bikes out there. Very few out of the thousands sold have failures.
What a completely unqualified response! How do you know this? You don't, you're guessing and are a million miles from the truth.
In reality, it's quite the opposite (verified by insiders and industry journos) and is actually the vast majority if not all bikes sold with these batteries, particularly the 900wH versions.

Owners aren't noticing and/or reporting them, it's not something one would expect and look for and most owners don't even take the battery out of the frame! So, would never know.
The cracks start as tiny almost imperceptible hairline fractures, only visible with magnification. It only takes one ride from new with light off road usage, this is how poorly designed and/or manufactured they are.

Personal case, the 900wH unit that came with my bike has only 47 miles under it's belt, mostly tarmac shake down use. The cracks from the thread bosses are visible with the naked eye.
I bought a second battery from CanyonUK, have never used it, checked it yesterday, nothing visible but under magnification there is a minute crack developing from one of the bosses! This unit had only been fitted to a stock bike to test before being dispatched!

Also, and importantly, the mounting thread bosses are NOT the only place cracks are developing although this is generally where they start. They are also occurring from the casing screw/bolt locations.

Idiotic, you cannot claim it is unqualified, and then ask how? after you have made your mind up already.

But there are valid answers that substantiate my claim. #1 Canyon has stated such. Not that I trust their rhetoric. But it matches what ive seen #2 this was never an issue online or in local bike shops. Very few warranty claims were filed through Shimano. These bikes have been out for years. One would have to be a dipstick to think people would not be vocal online if all the bikes had said failure points due to bad engineering that took place for many years.

Instead, what took place was a "few' complaints from Germany starting in spring, and most people just racking up miles and miles on their Canyons without a problem.

We sold 8 of these to our friends and family, and not one has failed as of yet.

What law is that?
"The European Union (EU) has several laws and regulations that protect consumers when buying goods and services, including a 2-year guarantee and consumer protection rules:

2-year guarantee
Consumers in the EU are entitled to a minimum 2-year guarantee on their purchases, regardless of how they made the purchase. This guarantee protects consumers from faulty goods or goods that don't work as advertised.

Conformity Guarantee
Consumers can return products purchased in the EU within two years if they are non-conforming. A product is non-conforming if it has a manufacturing defect, doesn't look as promised, or doesn't perform as promised.

Consumer protection rules
These rules ensure that consumers have clear information about the products and services they're buying, including the price, shipping costs, and delivery costs. They also protect consumers by requiring online marketplaces to indicate whether a seller is a trader or a private individual.

Repair encouragement
The EU is proposing new rules to encourage consumers to repair defective goods instead of replacing them. These rules aim to reduce waste, support the repair sector, and make it easier to repair goods.

The term "lemon" is often used to describe defective motor vehicles, but lemon laws can apply to a variety of consumer goods. "

And where it says that you can return goods to the seller?

Probably reading the regulation itself would prove illuminating. It might conceivably mean returning non-conforming products personally to Ursula von der Leyen in Brussels but I do have more than a few doubts about this possibility. 😂

Quoted from above:

"Conformity Guarantee

Consumers can return products purchased in the EU within two years if they are non-conforming. A product is non-conforming if it has a manufacturing defect, doesn't look as promised, or doesn't perform as promised."

Ridicilous law and I doubt that if it suits this case. But if it does, good for people who want's to return their bikes.

Just chatted to Canyon UK and was informed an update is being issued 11th December. Let's hope it is positive news and doesn't ruin Christmas 🙏

Well in UK and USA they have been authorizing returns already. A little complaining and they are setting people up with returns. But no details of how they will handle the return as of yet.

Ridiculous it is not. Protects consumers from faulty products. Here for autos, if you have the same issue that goes unresolved after 3 attempts to fix it, they are required to do a full refund. Most of the time it takes a lawyer to get involved to file for such. So to be technical, it may or may not apply. e.

Issues like this happened during covid, people had mechanical breakdowns, and or bodywork from accidents, and parts were not available. People were still making payments on leases and purchases, yet not able to drive their cars, some for over 6 months waiting. Lemon law did not apply.

As an EU citizen to be so ignorant and dismissive of an EU law that directly protects your consumer rights is
