Ford continued to delay a warranty repair on my car for months. Until coincidentally, I managed to get hold of an internal email from Ford showing that she was deliberately opposing the repair.
The internal document outlines Ford's policy to postpone warranty repairs for as long as possible, along with a list of possible excuses for their dealers.
Only after the intervention of a lawyer was Ford willing to repair my car. Customer service 0/10 - so far my worst experience with a company ever.
