Car Will Not Start Problems of Porsche Cayenne

The car cut out as I was crossing a intersection while in motion leaving the car disabled in the middle of a busy intersection, luckily other drivers saw the problem and went around me. All warning lights came on including the ignition lock fault. I turned it off and after 2 minutes it restarted. The next day the car would not start, the ignition lock fault came on, and then all of the other warning lights came on and the engine would not turn over and was locked in park. This happened once before in Feb 2017 when a corroded wires were found in a main bundle of wires in the drivers footwell. There was no water on that area and nor has there been any water on the car or the footwell. I have had weathertech mats in place hte whole time to prevent that. This is a safety concern that it could go dead in the middle of operation not just a starting issue. I have reviewed technical bulletin NHTSA 10056337 which does not provide any explanation for implying that the lack of feedback has lead to the factory not knowing to fix the problem. Porsche need to fix this problem the improperly spliced wires and the bundle need to be retrofitted in a way to protect them from ongoing corrosion that in my case happened happened twice the second time on 6,000 miles after the last in a car that is kept in a garage.
