When owners complained
A spike years after the car went on sale usually means a part wearing

NHTSA investigations into the 2011 Mercedes Benz GL350
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.
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 rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.C...
Recalls on the 2011 Mercedes Benz GL350
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

Upon deployment of the driver's frontal air bag, excessive internal pressure may cause the inflator to rupture.
Risk: In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death.

SERVICE BRAKES
- The hard brake lines from the going to the rear axle ruptured during light braking. The corroded sections have been removed and are available. - I had no indication of a problem until I went to stop the vehicle. I was able to slow the vehicle down but could not keep it from moving forward with out being in neutral. Had there been another car in front of me or in traffic, I would not of been able to stop. - The problem cannot be reproduced by a dealer, since the corroded and ruptured section of the lines had to be replaced. There has been no inspection of the issue since no accident occurred. - No warning lamps or any indication of a problem until the brake pedal was applied. Pedal was firm then suddenly went to the floor (repeatedly). Only until all the fluid drained from the reservoir did the "brake" light come on.

UNKNOWN OR OTHER
Malfunction with the air suspension. The vehicle is currently lowered and will not rise which is causing the tires to sit in a bent position and a horrible ride. The tires appear that they will detach from vehicle which is a safety risk for myself and others. After repairs from someone who presented themselves as a certified Mercedes’ mechanic, the issues still exist. The problems first existed about a year and a half ago, about 6 months after purchasing. I am making payments on a vehicle I am unable to safely drive or use for travel with my family. This should be a recall due to several vehicles jus in my area with same issues.

SEAT BELTS
THE LEFT REAR PASSENGER SEAT BELT IS BROKEN. THE MECHANISM WILL NOT RETRACT. WHEN I SPOKE WITH THE MERCEDES DEALERSHIP THEY SAID THEY HAVE BEEN SEEING THIS PROBLEM, BUT THERE IS NOTHING THAT THEY CAN DO. THEY ONLY RESPOND TO RECALLS THAT NHTSA INITIATES. THEY WOULD NOT REPLACE THE BROKEN SEAT BELT FOR FREE, BECAUSE IT IS NOT UNDER WARRANTY ANYMORE EVEN THOUGH THE CAR ONLY HAS 37,000 MILES, BECAUSE IT IS 5 YEARS OLD, THE WARRANTY WAS 50,000 OR 4 YEARS, WHICHEVER CAME FIRST. WE PAID OVER $400 TO REPLACE THE SEATBELT BECAUSE THIS IS A DEFINITE SAFETY ISSUE THAT NEEDED TO BE ADDRESSED IMMEDIATELY. WE HAVE PICTURES AND THE ORIGINAL PART IN OUR POSSESSION. WE KNOW THIS IS A PROBLEM WITH THIS MODEL AND WE HOPE YOU CAN ISSUE A RECALL. THANK YOU.

HELLO. MY VEHICLE HAS EXPERIENCED TWO SEVERELY ELONGATED TIMING CHAINS IN 30,000 MILES OF DRIVING. TOTAL MILES ON THE VEHICLE ARE 114,000, AND THE VEHICLE IS A 2011. I HAVE BEEN ADVISED THAT IF THE TIMING CHAIN FAILS DURING DRIVING, IT WILL CAUSE AN ENGINE STALL, AND MAY POTENTIALLY CAUSE SEIZURE OF THE TRANSMISSION AND WHEELS, CAUSING A SEVERE SAFETY HAZARD. AT A COST OF APPROXIMATELY $8,000, THE TIMING CHAIN AND ALL RELATED TIMING COMPONENTS HAD BEEN REPLACED APPROXIMATELY 15 MONTHS AGO, AND NOW, THE PROBLEM HAS RECURRED. IN SPEAKING WITH OTHERS, THIS IS NOT AN ISOLATED INCIDENT; HOWEVER, RECURRENCE OF THE PROBLEM SUGGESTS TO ME THAT THERE IS AN INHERENT DEFECT IN THE ENGINE THAT CAUSES TIMING CHAINS TO FAIL.
