NHTSA defect investigations
Federal safety investigators have looked into 2 possible defects involving the 2015 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.

Wheels & tires
The contact owns a 2015 Mercedes-Benz E350 equipped with General Tires, Tire Line: Altimax RT43, Tire Size: 245/45/17, DOT Number: 838RWC094518. The contact stated that while driving approximately 30 MPH and making a left turn, the front passenger's side tire suddenly experienced a blowout. The cause of the failure was not determined. The tire was replaced at the local dealer. The contact later discovered that the rear passenger's side tire had experienced outer sidewall bubbling. The manufacturer was notified of the failures, but no assistance was offered. The failure mileage was 25,000.
I purchased a pre-certified 2015 Mercedes-Benz E350 4matic sport with 19,550 miles on 3/9/18. Within the first 175 miles driven I have experienced a flat tire from complete sidewall failure in one tire (which was a newer, non-original) and two sidewall bubbles on two of the other original tires. The sidewall failure was due to hitting a small pothole while the bubbles seem to have been caused by normal driving. The tires are contiprocontact 245/40r18 which seem to have common sidewall issues from the complaints. For safety concerns I have ordered Michelin pilot sport a/s 3+, so will be out around $1,000 (plus the $255 cost of replacing the first blown contiprocontact, which has about 50 miles on it, but I do not feel safe driving on it).
