This survey is incredibly suspect ... as the author themself states, there's an inherent bias for non-american brands.

I find it surprising the FCA and GM cars are topping the list, while being notoriously unreliable in the car community.

Also worth noting that both Toyota and Ford have been ranked as worse than industry average.

I'm not saying that Tesla(s) don't have quality issues, but this survey seems pretty meaningless.

Perhaps it should be redefined as build quality, but it is still a decent metric worth analyzing.

I don't doubt that Tesla's are less reliable by other definitions, but I agree that this isn't a great measure.

Tesla's have lots of new and untested technology. That's their appeal. If toyota wanted to be less conservative and start using blazing new technologies in their cars, I'm sure we'd see the same issues there.

Teslas are notorious for software bugs that eventually get fixed. What i'm more interested in is whether Teslas end up lasting a long time. Electric motors are a lot simpler and so in a sense, I suspect they have the potential to last for more years with fewer issues.

It would be really interesting to take brands that have improved dramatically over the years, and do a thorough analysis of what internal processes they changed to achieve that result. You know that there are QA folks within each company doing that kind of analysis.

After doing that analysis, it would then be a fun project to try to apply those manufacturing or design process changes to software development.

I suppose in such a competitive and proprietary industry, such transparency is not likely.

Here's another source (consumer reports) that backs up the idea that Teslas are on the less reliable end:

My thoughts are that Tesla is a newer company, they are trying things that others aren't, and third, reliability never seemed to be a top goal for them.

Most product failures happen very early on, or very late in the design lifespan: https://en.wikipedia.org/wiki/Bathtub_curve

I think this is a bit misleading. The metric is "problems" per 100 cars. That could mean the car's transmission gave out or it could mean there is a software bug or paint issue that is causing the driver problems. In the case of Tesla it could be the case a lot of problems are due to software bugs that can be corrected over the air seamlessly for free. I think classifying each problem into categories with associated weights would help to make the metric more meaningful

I drove a rental Tesla recently. We were parked in a long line waiting to board a ferry and I was playing chess on the main console. When the line started to move, I tried to too and car just wouldn't go or start. People stuck behind me started getting impatient and honking while I was trying to figure out what had happened, turning off and on again, pressing random buttons, accidentally popping the trunk, etc. It took several minutes to realize that the car wouldn't start while you were playing a game on the console, so I had to quit the game, and then drive.

My point with this anecdote is that it seems to me that Tesla has many such features, some of which may change with software updates, and, given the expansive definition of "reliability" used here, perhaps this is a driver of issues.

I wonder what the rates would be if you restricted it to "issues requiring professional repair" or something like that.
