NHTSA defect investigations
Federal safety investigators have looked into 2 possible defects involving the 2011 Mercedes-Benz E350:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
Rear brake line failure
On April 10, 2020, NHTSA's Office of Defects Investigation (ODI) received a defect petition from Mr. Surjit Singh alleging premature corrosion of the rear brake lines in his 2013 Mercedes-Benz E350 sedan. The petitioner states that he was recently informed by a Mercedes dealer service department that his car had severely rusted brake lines that need[ed] to be replaced immediately at a cost of about $3300.

Suspension
We took our car into the local Mercedes Benz Dealership at Ft. Washington, PA for a routine service and PA inspection. Our vehicle is a 2011 MB E 4 matic and has ~70K miles. We received a call stating that the rear subframe of the vehicle had failed and was not considered safe and therefore did not pass the PA state inspection. We authorized the dealership to replace the component, which was done. The dealership suggested the corrosion may be caused by salt used for removing snow. The car was garaged routinely, washed including undercarriage routinely and the google search suggested that the amount of snow since 2011 was lower than normal. I explored the internet and it appears that this issue has been documented by others for this and other models of MB vehicles. …
The rear subframe has prematurely rusted. It had a shear failure at speed on the highway when I applied the brakes. The rear end of the car swerved, almost causing me to crash. I did manage to decelerate the car in a controlled fashion. I did not know the rear subframe failed at the time. This was confirmed by an independent mechanic several days later. After research, it looks as though a recall has already been issued for this issue in Canada and potentially Germany. The mechanic tells me that until the issue is repaired the vehicle is unsafe to drive. My and others safety was put at risk due to the failure of vehicle control at 65 mph on a busy road. The problem was verified by an independent mechanic. No police, insurance provider, or Mercedes dealer has inspected the car/damage, only an independent mechanic. …
