Example complaints

“I recently purchased this car. The rear back-up camera was in a flip flopped state. Meaning, what was displayed on the cabin screen on the left, was actually on the right plus the guiding lines on the screen were missing. I purchased and installed a new camera from Ford.

But, I wonder how long it will take to fray to raw wire? …”
