I will never buy another Tesla again for political reasons, but regarding reliability: their new models have always had reliability problems, but then reliability has always gotten much better within a year or so.
I don't know if the Cybertruck will follow the same pattern, or if the whole company has jumped the shark, but if we're looking for non-political opinions I would not necessarily write them off on quality issues alone.
The Model 3 and Y, particularly after the refreshes, are really good cars.
Political=> he did a full blown Nazi salute twice and has been working to have millions fired from their government jobs. The conservatives who don't seem as bothered by that have never been interested in EVs to begin with and his liberal fanboy customers will never buy from him again now. He is extremely unpopular in Germany and China's Tesla market is being out competed. I don't think that makes Tesla look good long term, so I'd be cautious about a long term investment with them like rooftop solar. That's just my opinion anyway.
