Ridiculous excuse! This button should work for the life of the car. Max presses probably a fraction of what other pushbuttons get per day! We have push buttons in applications EVERYWHERE in our world. Think of television remote controls... these get pushed and abused and last for years! Elevators, microwaves, toasters, yada... yada.....When you think of the wear and tear on that start/stop button over the course of 4-5 years especially if you are doing a lot of short trips during each day, it is not unreasonable to see it fail. It was a cheap diy repair and not a safety issue as far as I was concerned. It is also possible that some owners are pressing the button and holding it in until the engine starts which would cause issues. All that is needed is a one second press on that button to engage the start or stop cycle.
