Lexus is toyota. Accura is honda. So it’s really like: 1. Toyota 2. Mini 3. Honda 4. Subaru 5. Mazda Congratulations Japan.

It's incredible how the Japanese carmakers were able to perfect the auto manufacturing process and then proceed to hold that advantage for what, 30+ years now? It's not a secret how they did it, it's been studied to death, every manner of technology/expertise/management transfer has been tried, and still no one comes quite close enough to threaten their position.

I don't see how 'Tesla' is not top of the list here. For the 'Trouble Areas' I suspected they're normalizing over the 'length of ownership' which would bias the scores towards older car companies.

On the contrary, I'm impressed by how much Tesla has improved. They used to be second last, and the effort they've put into improving quality - especially on the Model 3 - is clearly paying off.

Very weird how EVs and ICEs are intermixed. I would expect vastly different results across different drivetrains, and probably even more differences across shape/size platforms (compact, sedan, truck, van, etc.).

There's a chart "How Electrified Powertrains Compare" which shows "Problems compared to gasoline-powered vehicles." You might be surprised to see that in fact EVs fare significantly worse than ICEs. I'd wager that they're mostly newer designs that naturally have bugs but instead of making modest changes to the car design in a new model, they're making significant/sweeping changes.

Oddly enough they don't state what the problems are. Meanwhile the ADAC (German car club) find that EVs have similar defect rates in components they share with ICE while having less engine issues. Overall, they conclude there is insufficient data for a meaningful statistic at this time:

In the end, they're both a type of "car". And they're judged on how reliably they "car".

It's especially important to see how they compare given the zealous push for EVs to replace ICE completely.

Tesla's reliability scores have always been pure and utter trash. This is the best result they have ever had. While other companies have a higher failure rate of major drivetrain components, Tesla is stuck somewhere between reinventing everything (thus lacking legacy knowledge) and not fixing things because they don't have the time/manpower for it. A great example of this is Model 3 Suspension failures. The Model 3 upper control arms are known to fail prematurely and seemingly, there is no fix. By all means, this is an extremely dangerous failure that can cause loss of vehicle control. Germany has a far more serious inspection process than the US and the result for Tesla is truly a disaster: https://www.autoevolution.com/news/tesla-model-3-is-the-car-...
