People show up with lists of things to check on their new M3 and so inevitably find something. Literally lists, with over a hundred items. If other customers did that for other brands, they would find just as many things if not more. On your last new car purchase did you look at panel gaps? Answer = no, because that is not rational. There are currently several threads of people taking their car in because they 'lost' 5% of their range even though it is easily found by google that is a balancing issue not a range issue. Imagine if everyone who didn't get rated mpg in their Audi took it in for service? There was a post a couple weeks ago about someone demanding tesla replace the plastic lining inside the trunk because it had a scratch...After a week of ownership (and kid duty) that piece on my car looked like it survived a grenade attack.
Tesla has its issues, but most of these new car 'service visits' are for dumb things that don't matter. Bloombergs' quality survey showed that Teslas are actually well above industry standards for quality on important things and basically, Tesla owners are a bunch of whiners.If something important actually happens to your car, tesla typically fixes it within normal industry timelines and continues to improve.
That isn't going to change. If tesla paid for more service techs then they would just be paying more money to fix dumb things. Tell people to stop being OCD on paint work and whatnot and then service centers will be like the maytag repair man.
