That reasoning makes business sense for future sales. Unfortunately, automotive companies are driven by quarterly earnings and accountants often influence policy.

The lack of heat issue develops slowly over time and mileage. By the time most Mirage owners realize they have a problem, they will be out of warranty. It's better for Mitsubishi (short term) to ride it out and just handle the few complaints on an individual basis. This is what they have chosen to do with the rear axle problem. They are still shipping new Mirages with deficient rear axles and they have known about that problem for at least 4 years now. To the best of my knowledge, there still is no Technical Service Bulletin for that issue.
In other words... Don't wait for Mitsubishi to come forward and admit there's a problem.
