NHTSA defect investigations
Federal safety investigators have looked into 2 possible defects involving the 2010 Mercedes-Benz E63:
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.
What 2010 Mercedes-Benz E63 owners say
Fuel & propulsion system
Have strong odor of fuel in cabin and outside driver's side rear of vehicle that has been increasing in intensity over the past couple of months. I removed the rear seat bench and the access cover for the fuel pump under the driver's side rear seat and found pooled fuel on top of the pump as well as a lot of dirt and grime showing that it had been a problem for some period of time. I dried up the fuel but the problem continues, and continues whether or not the tank is full or less than 1/2 full.
There is a fuel smell coming from the rear of the car. I remove the rear seat and verified the fuel sending unit is leaking. There was puddle of gas around the sending unit. Especially after filling the gas tank with fuel, the smell is much stronger. Other people have passed by my car while it is parked and have told me they small gas. I had the car serviced at Mercedes of gilbert in arizona. They verified the fuel sending unit on the driver's side is leaking gas. They want something like $1,350 for the repairs. My previous car was a 2004 Mercedes e55 amg. This car after thousands of complaints and NHTSA starting their investigation, had the same leaky fuel sending unit. Mercedes denied there was a problem and refused to fix it. Only after the NHTSA started their investigation did Mercedes admit there was a problem and fixed the cars under an extended warranty. …
