2014 Mercedes-Benz ML-Class Body & Structure Problems

IN MY NEIGHBORHOOD APPROACHING A STOP SIGN ABOUT 20 YARDS AWAY. THE CAR ALL OF A SUDDEN ACCELERATED AT A HIGH RATE OF SPEED. I WAS GOING TOO FAST TO MAKE THE RIGHT TURN AND THE BRAKES DID NOT STOP THE CAR. I ENDED UP RUNNING THROUGH THE STOP SIGN UP AN INCLINE AND INTO THE WOODS HITTING MULTIPLE TREES BEFORE COMING TO A STOP. THIS CAUSED OVER $18,000 DAMAGE TO THE VEHICLE (NOT INCLUDING DAMAGE TO THE UNDER CARRIAGE). NOT ONLY WAS THIS PRETTY FRIGHTENING BUT WHAT COULD HAVE HAPPENED IF I WASN'T IN MY NEIGHBORHOOD WHEN THIS TOOK PLACE COULD HAVE KILLED SOMEBODY. IT REALLY SHOOK ME UP. THANK GOODNESS THERE WERE NO KIDS AT THE BUS STOP. I WAS ALSO SURPRISED THAT THE AIR BAGS DID NOT DEPLOY. THE INSURANCE COMPANY TOTALED THE CAR SO NO ONE REALLY SEEMS TOO CONCERNED ABOUT THE CAUSE OF THE UNINTENDED ACCELERATION THAT TOTALED MY CAR WHILE DRIVING IN MY OWN NEIGHBORHOOD! THIS SHOULD NOT HAVE HAPPENED. I HOPE SOMEONE WILL CARE ENOUGH TO TRY AND DETERMINE WHAT HAPPENED SO THIS DOESN'T HAPPEN TO SOMEONE ELSE.

Power Sun ROOF is coming off the tracks of the roof which it is attach to. I feel this is an extreme safety hazard because I believe it will eventually come off my vehicle and cause a serious accident flying into another vehicle or even a pedestrian. This was fixed by Mercedes Benz [ BENZE BUSCH of NJ ] back in to 2018 and now it is doing it again.I Contacted the dealer again about this and they refuse to repair saying Vehicle is out of warranty.I also contacted Mercedes Benz corporate Headquarters and they refuse to acknowledge the problem.Obviously this is a defect in the vehicle. I researched that they have had similar problems with other vehicles SUN ROOF problems and they acknowledge those facts and repaired them. I previously filed a complaint with the NHTSA ID #11478665 but it seems that you didn't have all the facts. Please look into this matter again now that you do. Thank YOU
