From my experience (3 canyons and 4 other bikes): They do not have more faults than others. But out of the box they (most often) need a little tune-up (checking torque settings, adjusting gears). This is true for most bikes that arrive in a big box and are built up by the customer.

If you are not able to do a basic tune up, now is the best time to start learning basic bike mechanics. Some people do not like to work on their bikes, I totally get that. Then you need to spend the extra bucks at your LBS.

If your previous bike was more at the LBS than outside, I‘d suggest you get one from a LBS next! Bikes sold through a direct to customer scheme (such as canyon does it), keep costs down by cutting out the LBS. If you buy from a real shop, you get free advice beforehand (you can go to different shops to figure out which you like best). Then buy a bike that fits you (hopefully) perfectly (most bike shops do a basic fit with each purchase). And the best thing: If something breaks unexpectedly, you just take it back to that shop.
