The modern car runs on code as much as it runs on gasoline. Every command, from braking to unlocking the doors, flows through a layered network of processors built to regulate motion, safety, and comfort. When that network works, it feels invisible. When it falters, the entire vehicle can feel unpredictable, even hostile. Problems inside a car computer system rarely announce themselves gently. They escalate fast, leaving drivers staring at warning lights with no clear sense of what broke or why it matters.
