Tesla has won the Consumer Reports customer satisfaction survey for four years running, and by a large margin, but the folks arguing against it seem to be arguing "customer satisfaction" does not mean "customer satisfaction" or maybe that satisfaction has to do with the car but not the overall ownership experience. I haven't seen any data to support these statements.
Other studies of car owners' satisfaction have also found Tesla is on top. Based on its owner surveys, Strategic Vision found the Model S to be at the top of their Consumer Love Index -- the most "loved" among all vehicles.

According to Strategic Vision:
“Love” is the holy grail of the customer experience. Our research shows that true advocacy and brand loyalty begins not when buyers are simply “satisfied,” but when they truly love their experience!
The Consumer Love Index measures not just love of the car, but the overall ownership experience, including experience with the "dealer," for example:
Total Quality Impact
The customer’s assessment of the
complete ownership experience.
*******
Advocacy
Measurement of customer advocacy for the brand
and the dealership where they purchased their vehicle.

OP of course has the right to his opinion based on his own experience, but people who actually have tried to study these things systematically have found that Tesla owners on the whole are the most satisfied and "love" their full ownership experience more than any others in the industry.
