What 300 owners told NHTSA about the 2014 Mercedes-benz E-class Wagon

Vehicle subframe corrosion (manufacturer extended warranty offered). Rear brake lines corroded/leaking. Vehicle leaks fuel; steel fuel line corroded. Vehicle has about 105k miles. Minor fire started when yard maintenance came in contact with fuel saturated ground where vehicle had been parked/moved out of the way just prior. With rear suspension subframe springs corroded, vehicle bottom can contact road surface while driving, scraping steel exhaust with fuel present. EXTREMELY dangerous. Local Sunbury Ohio Mercedes dealership inspected then offered subframe replacement. Stated it was leaking fuel and not hydraulic fluid we originally thought. Brake, suspension and fuel line corrosion repairs were quoted in excess of $4,000, which was a "great deal" according to them "because the subframe would already be removed and would make it much easier."

FOR A COUPLE OF MONTHS WHEN I PUT MY 2014 E350 SPORT IN PARK IT WOULD JERK FORWARD. NEVER REALLY THOUGHT ABOUT IT BEING A PROBLEM. I WAS DRIVING MY CAR INTO MY NEIGHBORS DRIVEWAY AND WENT TO TURN AROUND AND JUST AS I WENT TO PUT THE CAR IN REVERSE, THE CAR PROPELLED FORWARD DIRECTLY INTO HER TREE. IF THE TREE HAD NOT BEEN THERE MY CAR WOULD HAVE WENT INTO THE FRONT OF HER HOUSE. I AM THANKFUL THAT I AM JUST SHAKEN UP AND A LITTLE SORE. I AM ALSO THANKFUL THAT I WAS THE ONLY ONE IN THE CAR DURING THIS FREAK EVENT AND THAT IF HAPPENED WHERE IT DID BECAUSE THE 2 OTHER TIMES THAT I WAS IN MY CAR THAT DAY IS WAS IN HEAVY TRAFFIC AND I WOULD HAVE DONE MAJOR DAMAGE TO MYSELF AND POSSIBLY SOMEONE ELSE. AT FIRST I BELIEVE MY SHOE GOT CAUGHT ON THE ACCELERATOR, BUT THERE IS NO POSSIBLE WAY THIS COULD BE THE ISSUE AS I WAS APPLYING IT TO THE BRAKE WHEN THE CAR PROPELLED FORWARD. FOR AS HARD AS I HIT THE TREE THE AIRBAG DID NOT DEPLOY. I WAS ABLE TO DRIVE MY CAR BACK HOME WITH ALL THE COOLANT LEAKING FROM IT. *TR
