NHTSA defect investigations
Federal safety investigators have looked into 2 possible defects involving the 2011 Mercedes-Benz E550:
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.

Takata recall. I bought the car new, received recall notices from mbusa in May and August 2016, stating that my driver's and front-passenger airbags have a defect related to safety. I have made four specific visits to the dealership in santa monica, simonson's Mercedes-Benz, asking that my airbags be replaced. Each time I've been told that there are no replacement airbags available.
Suspension all 20 →
The vehicle felt like it was all over the road at highway speeds. Took it to a mechanic and the rear subframe had become weakened with premature rust. The mounting point for one of the rear suspension arms had broken off of the subframe and was making contact with my gas tank. I called the dealer to see if there were any recalls. No recalls for this issue however there are a few reports on this website. I have also been on forums for my vehicle and it is a VERY common problem on these vehicles. From what i gather this is a widespread issue, and the fact that it could possibly puncture a gas tank and cause serious injury that something should be done to correct the concern.
When I parked my car there was a loud hissing sound near left front end but no smoke or anything from under the hood. When I drove it again I received a warning of (MALFUNCTION) when I was turning left the front left tire was grinding on the actual car and barely made it home. The car warning turned red and said pull over car too low. When I parked the car the front left side is now sitting on tire and touching the ground. Unable to drive. Not been investigated by a mechanic, insurance, etc. There was also an airbag warning before this issue. The contact has stated that she is disabled, and the vehicle is not currently drivable.
