Ahh, so you think the ABS module (which is still Bosch) has such a simple failure mode? 12V power isn't clean enough so it disables brakes? Or noisy communications cause it to block brakes? Geez man. Do you think every engineer besides yourself is incompetent? This isn't the Wild West. There are standard that automobile components have to live up to.
I didn’t say it would be a simple failure mode, or that it has anything to do with incompetent engineering on anyone’s part. It’s clear that the OP had some major electrical/electronic issue affecting hardware in different areas of the car systems before the issue.
if every automotive project always lives up to standard then why did VW have thousands of cars sitting for months because of a software issue, shouldn’t it all have been figured out during initial engineering And qualification?
How was takata, a engineer company founded in the 1930s not able to engineer, test and qualify an airbag without figuring out that moisture would affect it over the years and kill people when it went off?
How could GM and Delphi not engineer a ignition lock that wouldn’t lead to 124 deaths?
How did Boeing, a aerospace juggernaut for decades, not realized that their master event timer on their starliner capsule would go haywire during the launch to the space station?
It’s got nothing to do with a Wild West attitude, bottom line is complex systems fail in complex ways.
I once worked on a race car project with a professional driver testing the car, he came in after a run and said the car stuck at full throttle, We checked the pedal assembly and it was working just fine, smooth as can be, the logging data supported it, both fly by wire throttle potentiometers were showing that the pedal had been depressed. People on the team directly started talking about how the guy made a mistake, confused the brake and accelerator etc but he was adamant.
We ended up tracking down an issue with the return spring binding up under heavy vibrations down the straight, locking up the pedal.
Moral of the story is don’t always assume its user error, it’s could be a complex error that is easier to blame on the user than digging into and finding other potential causes for.
