Legal Question in Consumer Law in California

Against who for what? "A case" is based on facts that show that someone did something wrong, or failed to do something that they were obligated to do, and that misconduct caused damage. If the dealership did something wrong and that caused the engine to sieze, then, yeah, you probably have a case. But one thing happening after another thing was done, doesn't constitute proof that the thing done caused the thing to happen. It's called the "post hoc, ego propter hoc" fallacy. Roughly translated that means "after the fact, therefor caused by the fact." Not necessarily so.
