Rear subframe snapped under hard braking on the highway and caused my to veer into leftmost lane. It was terrifying and a severe hazard on the highway. Had vehicle towed to my house. I lifted and inspected my car and found the rear subframe was rusted and a crack straight through. The rear brake lines were also severely corroded and are very close to failing. Front brake lines have no corrosion. It seems that the rear subframe and rear brake lines have the same anti rust coating which are clearly not sufficient.

Mercedes Benz E350 2014 - Panoramic Sunroof rattling and squeaking noise/sound: This issue has been reported by many online, and it is a well known problem with E350. It starts with a little bit of squeak and metallic rattle noise here and there, and then after a year or so it is almost happening all the time as you drive the car. Dealer states that Sunroof Frame bolts have to be retorqued and loose bolts which rattle around have to be put back on. Estimated cost $712. If not a safety risk causing Pano sunroof to eventually fly off, it should definitely be a recall as many E350 owners have reported the same issue, and it is a manufacturer defect.

MY WIFE HAS HAD THE TRUNK LID CLOSE ON HER HEAD ON TWO OCCASIONS WHILE TAKING ITEMS OUR OF THE TRUNK. SHE INADVERTENTLY ENGAGED THE AUTOMATIC CLOSURE WHILE LEANING INTO THE TRUNK. THE FIRST TIME, THE TRUNK LID HIT THE BACK OF HER HEAD, THE SECOND TIME IT HIT HER FOREHEAD.

IN OCTOBER OF 2013 I LEASED A 2014 MERCEDES E350. THE VEHICLE HAD BEEN PARKED OVERNIGHT AT MY HOME ON 12/25/13 AND UPON ENTERING THE VEHICLE ON 12/26/13, I NOTICED A LARGE CRACK EXTENDING APPROXIMATELY 15 INCHES FROM THE BOTTOM OF THE DRIVER'S SIDE WINDSHIELD WIPER AND UP TO THE CENTER PORTION OF THE WINDSHIELD. WHEN I PARKED THE VEHICLE AT MY HOME ON 12/25/13 THIS LARGE 15 INCH CRACK DID NOT EXIST. I TOOK THE VEHICLE TO THE MERCEDES DEALERSHIP ON 12/27/13 AND WAS TOLD THE HUGE CRACK IN THE WINDSHIELD WAS CAUSED BY A SMALL IMPACT, ABOUT THE DIAMETER OF A PENCIL POINT JUST BELOW THE WINDSHIELD WIPER. THE EXTREMELY SMALL PENCIL POINT DIAMETER IMPACT CAUSED THE WINDSHIELD TO DEVELOP THE CRACK OVERNIGHT WHILE THE VEHICLE WAS PARKED AT MY HOME, SINCE THE LARGE CRACK DIDN'T EXIST WHEN I LAST EXITED MY VEHICLE AT MY HOME ON 12/25/13. I BELIEVE THAT IF SUCH A SMALL PENCIL POINT SIZED IMPACT AS ALLEGED BY THE DEALER, COULD CAUSE SUCH A LARGE CRACK TO DEVELOP OVERNIGHT WHILE MY VEHICLE WAS PARKED AT MY HOME, THE WINDSHIELD ITSELF IS DEFECTIVE AND THE WEAKNESS OF THE E350 WINDSHIELD POSES A SERIOUS SAFETY HAZARD. *TR
