NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2017 Mercedes-Benz E300:
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.

The Starting Current Limiter Recall (NHTSA Campaign 16V831000 / 17V114000): If your E-Class failed to start or struggled to crank initially, a defective starting current limiter can severely overheat the electrical lines to the starter, causing nearby components-including the battery assembly and main wiring-to melt and smoke. The above is exactly what happened. I was sitting at a red light and the car shut off and I tried to start it again and smoke started coming out of the right air vent in front of the battery. The wires to the battery were destroyed and part of the battery was melted. This is a certified pre-owned 2017 Mercedes E-300 4-matic. I just had the 100k mile maintenance done 2 months ago. The car is in perfect condition. New battery installed August 2025
