NHTSA investigations into the 2011 Mercedes Benz GLK350

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.

1 investigation is still open.

EA21002 Opened 17 Sep 2021 Still open AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE

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 rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants.

Recalls on the 2011 Mercedes Benz GLK350

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.

FUEL SYSTEM, GASOLINE

Mercedes-Benz is recalling certain model year 2011-2012 S400, S550, S550 4Matic, S63 AMG, C300, C300 4Matic, E350, GLK350, GLK350 4Matic, CL550 4Matic, and CL63 AMG vehicles manufactured from April 18, 2011, through July 12, 2011. Due to an irregularity stemming from the molding process of the fuel filter flange, the fuel filter flange may crack when operated in high temperatures.

Risk: If the fuel filter flange cracks, it will leak fuel which may lead to a fire if an external ignition source is present.

STEERING

My kids and I went into a football game and when we came out I used the key fob to unlock the doors but the vehicle didn’t recognize my key fob when I tried to start it. There were no lights or warnings leading up to this incident. The dash didn’t say anything besides “remove key from ignition”. We were stranded for 5 hours before I had to have it towed. It cost roughly $2000 to have it repaired with no clear reason for why it happened. It was a censor on the steering column that was somehow deprogrammed while we were in the stadium and suddenly failed to recognize its own key fob once it was inserted into the ignition. The anti-theft security feature kicked in and I could not get the vehicle to respond or bypass the system and it left me and 4 children stranded in a very dangerous area for several hours with no information as to why this happened or how to avoid it in the future. The steering column locked up when the tow truck driver tried to load it and caused a significant amount of added expenses on to the repair costs and towing costs.

FUEL/PROPULSION SYSTEM

I noticed fuel / gas smell from my vehicle. I looked up cause for this type of occurrence. I was referred to a recall bulletin for this particular cause - Recall Campaign #2013020002. My vehicle (VIN #) is not on the recall list. Both MB dealerships in my area state I would have to cover the cost to replace the Fuel Filter Flange. I am certain the Fuel Filter Flange is defective and should be listed in the recall. I pulled up the rear seat and removed the cover to expose the Fuel Filter Flange. There was gasoline on top of the Fuel Filter Flange. (I have documented with pictures).

When we fill up the SUV with gas, there is a very strong odor of gas outside of the passenger door & some odor "inside the SUV. We looked online Motortrend.com said Certain 2011-2012 MB CLK 350 4matic are being recalled for a potential fuel leak caused by a crack in the fuel filter flange, Dec 15, 2012.' We stopped by MBenz of Lynnwood, Wa and spoke Garrett, a service rep. Garrett said that this was not a safety issue and we can continue to safely drive the SUV. We disagreed! We are very concerned because we believe there is a safety issue, our SUV has a crack fuel line could catch on fire while we are driving and potentially anyone around us could be affected. We did not get a malfunction or error message.

Bradenton, FL

VISIBILITY/WIPER

Headlight bulbs failed. Owners manual states that the low beam bulb on the driver's side can be replaced by simply removing back cover, inserting hand and removing and replacing bulb. However, this is fraudulent. Every mechanic and the Mercedes dealers state that the bumper and possibly fender must be removed to replace this SAFETY item. The bulb went out on a trip and could not be replaced even though the bulb was readily available and I purchased it at a Walmart but could not replace it. Even though the Walmart replaced bulbs, after I waited 2 hours they told me they could not do it. I took it to two mechanics and they said they "did not have time" since it required disassembly of the vehicle. The Mercedes dealership said they could not provide an estimate because it required substantial time and disassembly. Now I have a car that has a bulb out, it cannot be driven at night, and to replace the bulb it requires an appointment at Mercedes and apparently hundreds of dollars of expense for labor. Like windshield wipers, tires, etc, etc, this is obviously a CRITICAL SAFETY ITEM and Mercedes has committed fraud in its representation that the bulb can be owner replaced. MY CAR NOW IS A DANGER driving at night. The NHTSA has statutory responsibility for the safety of vehicles and the internet has endless entries about the difficulty of replacing the headlight bulbs on this vehicle. I pay taxes. Do something.

FUEL/PROPULSION SYSTEM

I noticed the smell of fuel coming from my vehicle, specifically when I top off at the gas station. This is dangerous as fuel can combust if ignited. I took the vehicle to be service, to find out about the fuel odor and was advised of the NHTSA recall. Upon researching I see that although the NHTSA recall #12V557000 specifically covers this issue, when entering my VIN, the recall does not appear for MY specific vehicle, which is a 2011 GLK-350. It appears there are several affected vehicles not included in the recall. This is a failure on behalf of Mercedes Benz as it is simple to conclude that the issue includes more vehicles than initially recalled. These vehicles need to be included as well.

SERVICE BRAKES

There were two incidents, one when my daughter was driving and one when I was driving. We were on a highway going 65 mph and had to brake as we came upon traffic. The car fishtailed/swerved back and forth out of control several times until we could bring the car to a stop. I had to pull onto the shoulder so I didn’t hit any of the cars near me. It was terrifying and I felt lucky that I didn’t have a serious accident. When I got home, I took my car to my local mechanic who inspected the car and said my rear subframe was cracked and rusted out!! After doing some research and talking to the Mercedes dealership where I bought the car, this is a widespread problem with several different models over many years, but they have not issued a recall. Apparently the frames were not rustproofed properly so they are rusting/corroding from the inside out. These frames should last the lifetime of the vehicle with no issues!! There are thousands of people driving their cars out there with this problem and they have no idea that their cars are UNSAFE to drive!!! Someone is going to get killed if Mercedes does not issue a recall for this problem. They recently sent an internal memo to all of their sales and service managers in the US saying they will offer an extended offer on the rear subframes. This does NOT help because many people are unaware of the problem and haven’t received notification that something could be terribly wrong. Mercedes has know about this problem for years and Canada and Europe issued recalls on the rear subframes 2 years ago!!! How can Mercedes USA allow their customers to continue to drive UNSAFE vehicles?!? A class action has been proposed for this problem because Mercedes has been so remiss in their responsibility in protecting their customers. Please please please bring this to light before someone gets injured or killed!!!!

ENGINE

I'm having the same issues as described in Recall no. 12V557000. However when I called Mercedes they mentioned that my Vin wasn't part of that recall. I don't understand how can that be when my car is 2011-2012 glk350 model as described in recall and I smell gas, can see gas leaking and the flange where my fuel filter is cracked as well as the flange to the fuel pump side. This car as well as many other Mercedes have two separate flanges that are prone to crack and not just the fuel filter side but the fuel pump side as well. there's many forums where they all have complained about this issue. If you can smell gas, there's obviously fuel vapors leaking and not to the mentioned the physical leak that is landing everywhere you drive. This is a serious fire hazard and is extremely harmful to my kids and passengers.

If you can smell gas, there's obviously fuel vapors leaking and not to the mentioned the physical leak that is landing everywhere you drive. This is a serious fire hazard and is extremely harmful to my kids and passengers.

FUEL/PROPULSION SYSTEM

Fuel/Propulsion System - There is a gas leaking from somewhere above the gas tank. I did not have this fixed yet because I see a recall for this but my VIN wasn't included in the initial recall. There are 17 other complaints on here for the same issue but we haven't been included in the recall as of today 1/2/2023. The recall that fixed other 2011 GLK 350s is NHTSA CAMPAIGN NUMBER: 12V557000 (FUEL SYSTEM, GASOLINE). My car is available for inspection upon request. I am very afraid of a fire because the tray underneath the car on the passenger side is full of gas & the tray is right over the exhaust. I stuck a large cotton swab in the tray to soak up the liquid & since it smelled like gas I tried to light it. It caught on fire immediately. This is definitely a safety hazard as it can ignite if a spark or lit cigarette would happen to bounce up in there. Yes it is unlikely but I have seen stranger things. The tray holds a large amount of gas and is directly under the gas tank. The check engine light came on and the diagnostic machine says fuel evap control system leak. A mechanic looked at the leak after taking the rear passenger tire off and finding the gas pooling in that tray. Odometer reads 145,000.
