2010 Mercedes-Benz E350 Body & structure Problems

Car was found to have the rear subframe corrosion for issue. But also the brake lines were corroded very badly. They should be covered under the rear subframe extended warranty replacement. The rear brake lines are an frequent issue and almost always shows up when the subframe begins to rot. Also the pattern of the corrosion seems to be consistent across multiple incidents. Look at photos I uploaded and the Reddit post; identical. Look at this post from Reddit, almost identical corrosion on the rear brake lines as mine. Furthermore, it always is the rear brake lines, almost never the front. This is a manufacturer issue that needs to be looking into.

Rear subframe corrosion and failure. Based on my queries this apparently a common issue. I am adding my report to add weight to this common issue. Vehicle is approximately 13 years old, is in good condition, and has not suffered any accidents affecting the rear subframe. Overall only minimal rust or corrosion is found during a visual inspection while on a lift. This vehicle has passed annual inspections as required by Virginia state law. The rear subframe has rusted from the inside. This corrosion was not visible from the outside, which is why it was not found in the annual inspections. Due only to this internal corrosion, the left-hand (driver) side of the rear subframe has broken loose where the rear wheel's control arm is attached. This removes one of the rear wheel's primary attachment points, making the vehicle unsafe to drive.

Per the technician: "the rear subframe is rusted out and the lateral strut arm is starting to break away". Because of this issue, the car unknowingly presented a safety risk to occupants and other drivers. A failure of the subframe or connected components could have resulted in a serious accident. Photos are attached. The vehicle is currently available for inspection upon request. There were no warning indicators to this issue. The issue was found only because the car was being serviced for brake pads. Mercedes Benz USA customer care said there was no recall or other warranty covering the issue and said the vehicle was outside their "good will assistance program". The vehicle is no longer able to be driven.

During maintenance check, mechanic indicated rust on the rear subframe that can lead to failure. Failure on this car would cause a puncture of the fuel tank due to car design. Upon further research, this is a well known issue with MB and is covered as a recall in all countries other than the US. Please encourage Mercedes Benz to do the right thing and issue a recall for this defective component, to avoid serious accidents.

MOLDS AND MILDEW BUILD UP IN THE AIR CONDITION DUCTS PLACING PEOPLE WHO ARE SUSCEPTIBLE FOR INFECTION (PEOPLE WITH WEAK IMMUNE SYSTEM) AT RISK FOR FATAL INFECTION. THE DEALER STATED THAT THIS IS A KNOWN AND COMMON CONDITION FOR THIS CAR BECAUSE THE AC BOX DOES NOT DRAIN THE CONDENSED WATER. THIS IS BECAUSE THE WAY THE CAR WAS DESIGNED. THE DEALER RECOMMENDED TURNING OFF THE AC FOR 30 SECONDS WHILE KEEPING JUST THE FAN ON EVERY TIME BEFORE TURNING OFF THE CAR TO DRY UP THE CONDENSED WATER ON THE AC COILS, NOT PRACTICAL. THE DEALER HAS A KNOWN SERVICE TO DISINFECT THE AC SYSTEM BUT BECAUSE OF THE CAR DESIGN COULD NOT GUARANTEE THAT THE CONDITION WILL NOT RETURN. THERE IS NO WARNING OR ANY INSTRUCTIONS IN THE MANUAL REGARDING THIS POTENTIALLY FATAL CONDITION FOR SUSCEPTIBLE PEOPLE. *TR
