>The J.D. Power US Initial Quality Study, which gauges problems encountered in the first three months of ownership. A very questionable definition of "reliability".
It's not a good measure of reliability, but it's a good measure of quality control, where Tesla seems to be sorely lacking. I've had two Model 3s, and I love the car. I had one last year that I had to return when I changed jobs, but I loved it so much I immediately ordered another. With that context, the QC is really poor. The first one I got last year had lots of cosmetic issues that I spotted when I picked it up, mostly paintwork. I missed the fact that the cloth on one of the speakers was damaged until it was too late. The Model 3 that I got this year was delivered in March, just before lockdown, so I didn't get much chances to use it at first. I just collected it today from the service center where it had been to have a scary fault fixed. I was driving along when suddenly a loud chime, and regen braking was disabled and the handling changed completely, and the car no longer decelerated when lifting off the accelerator pedal. An alignment issue that was a quick fix (aside from the four week wait for an appointment and the two hour round trips to drop it off, and then collect it). I separately now need to wait for a mobile repair next month to replace a parking sensor. These sort of things should have been caught before the cars left the factory.
