I am very interested in the BYD LFP blade batteries. A lot of the BYD BEV's look great.
My #1 concern about Chinese EV's is the implications of Chinese government ambitions around Taiwan and how that could impact BYD's sales outside of China.
As far as service nightmare, I have long list of complaints about my Nissan Leaf. Nissan still doesn't have a fix for a potential battery defect recall causing overheating and fire risk during L3 DC charging. Recall has been open for 1+ year with no fix. Good thing is since my oldest daughter just uses it as a College commuter car, we don't need DC Charging. The people that regularly used DC charging for their Leaf, I guess they are SOL. The seat sensor has gone out twice on my Leaf for the front passenger seat which has been a $1k fix both times, not covered by my extended warranty

. The only service I have needed in 2+ years of ownership for my Y, a tech came to my house and did the service in my garage. I rotate tires myself since my Dad has a 2-post car lift. My biggest complaint for my Y is how Tesla did the access for the Cabin Air Filter which is dumb. This was a little bit off-set that it only cost me $80 for a tech to come to my house and change it out and it is a 2-year cycle for the Y cabin air filter instead of 1-year I am used to for most cars. Interesting enough it looks like the HEPA filter has better access for it's 3-year service. Currently 34k miles on my Y and I expect I will have to put new tires on the Y sometime this year, keeping a close eye on the tread but so far appears to be wearing fairly evenly.
