This concerns the rear view camera.. It operates sporadically, or intermittanally,first time inn didn't work as expected it blanked out and i hit a tree... As i backed up it did not show anything behind my car.... So i backed into a tree... Following that i made an appt. At mercedes dealer in newton nj. , explained what had happened, service manager stated he never heard of that problem, they checked it out and found no problem.... Approximately a 10 days later as i was backing up in driveway i backed into a pickup truck that was not seen on the screen.... My daughter was watching intently after prior crash.... Never did the image of the pickup show on the screen.. $5887. 00 in damage later to truck and nearly the same on my card called mercedes customer service? Got to their voice mail, left a message to return my call ,that it was quite important, a week later i still have not heard from them!!! I have chills when i think how this problem could manifest itself in aster parking lot, or more importantly in a school parking lot... A tragedy because of someone ignoring the problem... Hopefully your organization will not ignore this very real situation.... I never want to hear that something that is shown on google to be recalled hundreds of thousands of times is still occurring, i find it very disheartening that a $95,000 mercedes suv would continue since 2016 to have this recurring problem without being corrected. I'm sure there have been horrible instance of a child being injured or killed.... Please address this best you can.
