Forward Collision Avoidance

Most of the incidents have been when no other vehicles or impediments are anywhere close by.

Over the past 14 months, the emergency breaking system has gone off approximately 25 times during non-emergency situations. Most of the incidents have been when no other vehicles or impediments are anywhere close by. This has created a very significantly unsafe and ongoing situation for my family which so far are being ignored by Mercedes Benz.

The glass panel between the windshield and the sunroof spontaneously shattered. I wasn't aware of this and had just noticed increased wind noise while driving for a few weeks until I noticed that it was due to shattered glass panel. It is cracked almost all around and somewhat dislocated. Upon close inspection in can be seen that cracks run throughout the glass panel. There is no single point of impact of a possible foreign object, so I can rule out the possibility of something hitting it with high confidence. I took it to the dealership but they refused responsibility under manufacturer warranty, claiming it must have been an object hitting it and quoted $3,815.10 for repair. I have detailed pictures showing no impact marks.

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. thank you there were 2 incidents, [XXX] and [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
