Quote: “Here, I would argue for a new replacement car.”
Well, one could try to argue that point, but the odds of winning that argument are somewhere between highly unlikely and impossible. This type of situation is why cars come with warranties, and why states enacted so-called Lemon Laws that come into play if problems cannot be rectified under the terms of the warranty during a specified period of time.
Consumers have recourse under existing warranties and under existing statutes, and as a result, manufacturers are unlikely to offer relief that goes beyond those forms of recourse. The manufacturer is entitled to a reasonable attempt to fix the problem, and the definition of “reasonable” will be found in the text of the Lemon Law for that particular state.
