I am reminded of the Mercedes-Benz Sensotronic Brake Control (SBC) system that was developed by Daimler and Bosch. It was in two mass-market models, the E-Class and the CLS-Class, and it was so unreliable and expensive that it was replaced with a traditional brake system during mid-generation refreshes for both models. Mercedes-Benz USA has also had to give the brake system components an extended warranty to not lose goodwill with its customers. I believe every single Mercedes-Benz with SBC in the USA is still under warranty with no mileage limits? Definitely not worth the headache despite having a backup system if (or rather, when, as the control unit had a fixed lifespan) the system fails and a separate auxiliary battery just for the brake system. I believe back in the day it was several thousand euro to have the SBC pump replaced when it gave out?
