Just had the warranty executed but when I got the car back as soon as I put it into reverse I was warned the rear brake assist wasn't working. The image from the rear cam when seen from above has a purple/blue tint to it. Has anyone else run into this? The thing that pisses me off is that my dealer has a pick-up/drop-off service so I find it hard to believe it wasn't noticed by the guy that drove the car back to me, or was it even tested before he got in to deliver it?
