NHTSA ID 11511213 · filed Mar 10, 2023

My 2015 E350 with only 40,000 miles was diagnosed to have a rotted and detached rear sub frame . Seems to be a common problem because of defective metal used by the manufacturer. There seems to be a lot of others with same issue I found on the internet . While Mercedes’ Benz has no recall as of yet. While driving on the highway , while at 50 to 60 mph. The car would sway and feel like it was sliding . After hitting the brakes the car would pull drastically to one side . After inspection at my Mercedes Benz dealership they told me that it is completely rotted and broke apart, this is a life safety accident since it could disconnect and hit gas tank and rip apart brake lines. The rear axle would shift and possibly fall out. While driving this car it put my family in complete danger . There were no signs , warning lights etc . That could have made me aware of the severe situation.

I PURCHASED A PRE-CERTIFIED 2015 MERCEDES-BENZ E350 4MATIC SPORT WITH 19,550 MILES ON 3/9/18. WITHIN THE FIRST 175 MILES DRIVEN I HAVE EXPERIENCED A FLAT TIRE FROM COMPLETE SIDEWALL FAILURE IN ONE TIRE (WHICH WAS A NEWER, NON-ORIGINAL) AND TWO SIDEWALL BUBBLES ON TWO OF THE OTHER ORIGINAL TIRES. THE SIDEWALL FAILURE WAS DUE TO HITTING A SMALL POTHOLE WHILE THE BUBBLES SEEM TO HAVE BEEN CAUSED BY NORMAL DRIVING. THE TIRES ARE CONTIPROCONTACT 245/40R18 WHICH SEEM TO HAVE COMMON SIDEWALL ISSUES FROM THE COMPLAINTS. FOR SAFETY CONCERNS I HAVE ORDERED MICHELIN PILOT SPORT A/S 3+, SO WILL BE OUT AROUND $1,000 (PLUS THE $255 COST OF REPLACING THE FIRST BLOWN CONTIPROCONTACT, WHICH HAS ABOUT 50 MILES ON IT, BUT I DO NOT FEEL SAFE DRIVING ON IT).
