2021 JEEP WRANGLER

The video for my backup camera became intermittent, then stopped working. I brought it into the shop. They say the camera is not the problem and that it is either a connection under the dash or a radio problem. The next diagnosis step will take 3 hours and $675 just to take the dash apart. This is a safety issue, a defect in manufacture, and not related to wear and tear. In researching online, this is appears to be a complaint that a number of others have had.
