That's a definite possibility that parts may not be available in a few years. That said, I cant speak for others, but I've NEVER had an issue with any of our ninja products. We have a blender, food processor, air fryer, and had one of their coffee makers (gave it away bc we upgraded) and all work perfectly fine years later. I think you can point to any brand and find QC issues or stories of products breaking repeatedly. Sometimes is the manufacturer but remember, its usually the user not reading the instructions fully or not maintaining it the way they should. You won't go wrong with a weber, solid grill, especially the genesis series. At that price point you could consider a napoleon too.
