NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2015 Mercedes-Benz GLK250:
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.

Engine & cooling
The DEF exhaust system has failed. It was replaced before under a recall. The warranty was previously extended on the system but I am outside of the mileage window but inside of the time window. I have $6000 in repairs so far and am trying to get assistance. I have been dealing with issues since October 2024
While driving on an interstate highway during rush hour my Mercedes glk suddenly slowed down to about 30mph. The car was unresponsive and would not accelerate. A .message that said 'inoperative see owners manual' appeared. We turned off the car and it started up without problem. We were very fortunate that we were able to pull over, as there is repair work being done and part of the highway didn't have a shoulder. We were lucky that we were not hit. This is very dangerous and needs to be corrected before someone gets hurt.
Electrical system
The driver's side seat failed. Due to a seat electrical harness failure the seat became stuck and neither the seat seatback or headrest could be moved. I could comfortably still reach steering wheel and pedals but my wife could not safely do so. The car has approximately 36k miles on it. I paid to repair this $831 negotiated down from $1600+. This is a pressing NHTSA issue because on the repair invoice the technician noted that a 40 amp fuse had been installed in a 30 amp socket. Presumably it came from the factory in this condition. The car has only been serviced by MBZ dealers - 2, palm springs and sandiego- and to my knowledge no one has touched the fuses or box. The electrical system from the factory is running 40 amps on a circuit designed for 30. …
When driving, the steering wheel locks and I can no longer steer the vehicle, it locks in a way that I cannot move the steering wheel at all, which may cause me to crash if I am at a dead end road and need to turn. I have been trying to contact the manufacturer for resolution but have not received any responses. This was a recall back in 2017 under NHTSA Campaign Number: 17V-595 for 2015-2017 Mercedes Benz cars, with the component of Steering/Electric Power Assist System. I am not sure why my car is not listed in the recall since it does have this issue.
