> No, it's not. That's why some manufacturers offer much longer warranties than others despite having similar reliability numbers. Warranty terms are driven by the business and encompass a lot more than mean time to first failure.

What's an example of this controlled for the price of the car?

Warranties are a good approximation in the context of cars. Virtually all other consumer devices have a 1 year warranty so it's not really a distinguishing feature.

In any case, warranty aside the reason I even brought it up is because many manufacturers warranties imply potential for up to 30% degradation after about 8 years which is why I used the numbers I used (https://www.recurrentauto.com/research/how-long-do-ev-batter...)

According to Consumer Reports, Lexus is the most reliable brand and Lincoln is the least reliable. Cars from these brands are similarly priced. Both of them offer a 4/50 basic warranty and a 6/70 powertrain warranty.
