As the title asks, I've got a Ghost system fitted and I took my car in for a service today and to have some issues looked at; the massage function on the seats goes a bit crazy sometimes, handbrake is a mystery as to when it activates, gearbox sometimes doesn't activate. I told the technical about the ghost system as he had to take it for a spin to try to replicate the issues. He had never heard of anything like it despite being a mechanic god according to him. His opinion was that it was the ghost causing the issues and that it would invalidate the warranty. Anybody heard anything about it invalidating the warranty?
