The computers are, by far, the most reliable parts of a car. They’re not subject to mechanical stresses or wear, and the real-time/embedded operating systems are far more fault resistant than desktop/phone OSes. The computers also mean that you can buy a $20 OBDII scanner and have the car tell you what’s wrong with it. Maybe an extra $10 for an app that will decode most of the manufacturer-specific codes. The difference between those $30 diagnostics and the $10,000 system the dealer uses is mostly that the dealer system includes all the manufacturer codes and step-by-step directions for fixing each fault.
Thanks for this, it makes a lot of sense actually. Oh well, my mom has her car and the warranty she will hopefully never need, but it’s there if she does. I guess it all comes down to care tactics in the dealership, pressuring you to buy warranties and such that you may not need and cannot buy at any other time except right then.
I’ll be sticking with the recently used philosophy for the future though.

They can also change things, like idle speed. You also need one for any form of electric vehicle.
