A warranty IS a "legal" guarantee. That's its literal definition.
Warranty is not exactly a legal guarantee, it is just an agreement between two parties. A legal guarantee is governed by the given country's law. In my country, for example, there is a 2 year guarantee on any new device that's governed by the country's law. A defective device or part of it has to be replaced or whole device replaced or refunded within the 2 year period. That is, it could be on the last day of that guarantee. It is the seller, who has to do that, and no seller will sell anything from any manufacturer, if that manufacturer will not abide by the country's laws. All those shops, internet or stationary, don't buy the devices from the manufacturer, but the sells the devices sent to them by the manufacturer, or by its agent, and what's not sold in a given time frame are sent back. The seller pays for only the sold items, and after a certain agreed amount of days, most times, within 4 weeks. Anyway, the consumer's rights are much higher than the manufacturer's rights, or the seller's rights in my country.
In any event, me and a coworker both have Apple Silicon Macs and both of our bluetooth devices fail regularly since Sonoma. It happens about 3-4x per day for about 10 seconds, then works and connects.
In the matter of Bluetooth cutting itself off, it is a normal thing is many devices, Android, Linux, Windows or even in Mac. There are lot of reasons why that happens, and sometimes there is no why, it just happens. The best way is to disable and re-enable Bluetooth. Most times, the Bluetooth module in the device cannot connect with a few external Bluetooth devices. This happens when those external devices are fighting each other to get the connection, and by doing so, break each other's connection, or everyone's.
If that happens, it means the Bluetooth module is malfunctioning, as it cannot hold the connection(s). The Bluetooth module also takes lot of energy. If a connection breakage happens with many external devices connected, better to disconnect few and leave only the most important ones connected. Or, if you find that a headache, show your Mac to a technical person, so that person can physically check it. Otherwise, revert to an earlier OS, if that, as you say, worked well for you. If you continue to state that the fault is in the new OS, then send a feedback.
(Here's an article in LinkedIn why your Bluetooth device fails sometimes.)
