Obviously, the internet is calling BS on this 'survey', as the 'Shanghai Model 3' was shown to have many quality control issues even in cherry picked media test samples. Also German brands rank much better than Japanese brands which is also counter-intuitive. Just like J.D.Power's 'Initial Quality Study' which has been accused for being rigged to make American brands look better, this report is also not representative of true quality of a vehicle especially in the long term.
This survey tracks the number of complaints of ALL vehicles sold, which means older models will naturally rank worse as they age. The TM3 has only been sold for 8 months, and delivery on a large scale only started 3 months ago, so almost all TM3 owners surveyed have only received their car for a short period of time.
There's also the problem that people buying Teslas and premium vehicles are less likely to file complaint (for example a life-threatening malfunction is considered a 'minor technical glitch' to Tesla owners), while buyers of cheaper cars are more concerned with minor issues.
