That is not a software or driver issue. the line is causes by either a bad pin to one of the lcd ports or a bad cable hookup. It rather sucks that it was an issue that they should have caught before they let the car leave the lot with you. But likely as with any dealership, they figure it's better to give the customer the car than hold it back. When I got mine, they had 4 days they said it would take from when we signed the deal to when I could pick up the car. supposedly to prep and get the car ready. we showed up and ended up waiting for over an hour as the car wasn't finished. Mine went out with all sorts of problems and had gone back to the dealership quite a few times. I look at it now as since they pissed me off enough by the attitude, any single fault gets brought in and the service manager now deals with me and I give him the list of what I think his wrong and then he goes out with me to look and if it requires a drive then he comes. I figure that i might as well get the perfectly working car and not let anything slip by that I have a question about.
