Do you have the link to the actual survey numbers? Otherwise from the link provided, I think you are also bias. The statement stated says nothing about the numbers, other than it was "higher." I would want to see the numbers broken out to be sure it is indeed really the majority. Otherwise, all I can conclude from the article is the fast charging network is why people like a certain brand. If this is the case, going forward, more people will want other brand because the charging network is getting better and better.
O btw, I have the opposite experience. I also had another EV on a lease, and from day one to return date 3 years later with 45K miles, no issues. My tesla had tons of issues mostly addressed before the warranty was out. Though there are now more problems in addition to the usual battery problem.
I doubt you'll get the actual data, but here's JD Power's direct interpretation of their data: 2021 U.S. Electric Vehicle Experience (EVX) Ownership Study
"The study finds that 95% of EV owners whose overall ownership satisfaction exceeds 900 points say they will purchase another EV. Nearly two-thirds (64%) of these owners say they “definitely will” repurchase the same brand. However, likelihood to repurchase the same brand lessens as satisfaction declines. Among owners whose satisfaction is between 600 and 750 points, 77% indicate they “definitely will” purchase another EV—although their likelihood of repurchasing the same brand is only 25%."
So basically, the higher the satisfaction score, the more likely the owner is to rebuy that brand. Seems rather obvious isn't it?
Then if you scroll down to near the bottom of the page, they have the average score for each model, with i-Pace and e-Tron ranking dead last. I suspect that podcast missed that the stat only applies to cars who scored below 750 in the owner satisfaction score.
Edits: Oops, mis-interpreted the JD Power results myself. Wish they would provide the actual data too!
