I bought in 2013 and consider myself an early adopter. However, I am far less forgiving of Tesla's faults today than I was two years ago. I was willing to forgive a lot in 2013 because it was a new product by a new company. However, Tesla has fallen woefully behind in maintaining the vehicle's software, and its regular software updates invariably break something that was previously working. Tesla has shown an unhealthy obsession with acceleration performance at the expense of almost everything else, it seems. As soon as Tesla gets something "good enough" with a minimum feature set, like the navigation system, it seems to forget about it.
Version 7 of the car's operating system was a huge step backwards that left me questioning how decisions are being made at the company. The continued problems with drive units has me wondering the same thing. Elon's demotion of Jerome Guillen as a scapegoat for poor China sales left a bad taste in my mouth, especially when it was Elon's decision, ultimately, to enter markets that he was absolutely unprepared to enter. Witness Hong Kong and the fact that Tesla never bothered to apply for regulatory approval of Autopilot. Now the feature has been pulled by government order.
Current buyers have every right to expect big things from Tesla, not the least of which is quality. I've been noticing that despite Elon's insistence that hundreds of improvements have been made to Model S, I continue to read about the same recurring problems with recent builds that have plagued owners since 2012. I continue to hear about lack of communication from delivery specialists, continued delivery delays and changing of dates, and the continued lack of QC causing some horrendous initial quality problems for a car of this price tag.
It is my opinion that Tesla is unprepared for what may be coming.
