Unplug it and spin the blade hub by hand; if it feels rough wobbly and or has up/down play, the jar bearing is failing and swapping the blade assembly is usually an easy, cheap fix. Make sure the jar is fully seated and locked on the base, then run a test with water; if it’s still jumpy, put the blender on a rubber mat or folded towel and start on low, ramping up slowly. Smaller batches with a bit more liquid can also calm vibration a lot.

Adding one thing - I pair your container limit with a quick 3F check: fits my life now functions without fuss, and a true favorite - if it fails two, it goes. For small-town realities, I add a replacement threshold: only release it if I can replace it in one errand and under a price I’m okay with; otherwise it lands in a dated 30-day maybe bin and leaves if untouched. To keep momentum in short sessions, I clear one micro-zone or surface to 100% each day so there’s a visible win and no backfilling.
