I believe these studies to be problematic for many reasons. The first is because they measure owner satisfaction, but they make zero effort to measure owner expectations. Are the expectations for people buying Teslas much higher than people who buy from other manufacturers? Are they more sophisticated of a buyer and think more deeply about their car?
The second issue is they also do things like compare the Rivian R1T to the Model 3, which is half the retail price and less than a quarter of the manufacturing cost (Rivian takes huge losses on their sales).
The final issue I'll mention is that JD Power makes almost all of its money from traditional car manufacturers. This is a huge conflict of interest and there is zero legal accountability.
