So, you have a handful of anecdotes here of varying experiences. It doesn't really add up to data.
Some people, such as myself, had terrible experiences with quality/reliability. My 2017 Model S had the following replaced in the first 5 months: battery (
the battery, in the first week), A/C unit, front wiring harness, and MCU (which is the 17" display and the computer that drives all the functions therein). None of the vehicles I've ever owned required warranty service (4-5 years of ownership each). This is not a testament to all Tesla vehicles, as it is a single data point. My second Model S (2019) hasn't had any equipment problems as of yet (3 months of ownership).
If we step back and look at many, many data points, you find this:
Tesla slips several spots in Consumer Reports reliability ranking
This is not forum bias. This is customer survey
of all makes, which is probably the best dataset we have (unless Tesla is providing data on the average warranty services per vehicle).
Some people will erroneously bring up "owner satisfaction." This is not a metric of reliability or quality. Tesla has very high owner satisfaction (by the same organization above). The questions, "Do you like your car?" and, "Would you buy another Tesla?" are not proxies for "What components of your vehicle have required service/repair under warranty?" There are many reasons the former questions can result in favorable answers, but the latter question does not, which is mainly predicated on the former questions being subjective/qualitative and the latter being descriptive/quantitative.
Some people will also erroneously define "reliability" as the ability for the vehicle to transport itself and at least one other person from point A to point B without abject failure that causes the transport to abort. This definition creates a false dichotomy, wherein many parts of the vehicle can fail without incurring a failure of "reliability."
