I had my 2014 Mazda CX5 for what will be a year in March. Just recently the backup camera stopped working. It would show a blue screen or scrambled video of what's behind me. The only explanation I can give for it to stop functioning properly is the massive amount of snow, salt, and water that we had in the North East (Central NJ). Other than I have no idea what happened but I would like to see if this issue is common or not? Regardless I have the 3 yr 36k warranty and will be taking it to the shop to look at.
