NHTSA investigations into the 2014 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 2014 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.

Freeport, ME 1 injured

UNKNOWN OR OTHER

Rear powered tailgate closes by itself. There is no warning. It closes VERY rapidly. This hit me in the head, but I am mostly concerned with others, such as elderly people and children. It could easily cause a concussion, or worse. I have contacted MBUSA advocacy at 1-800-222-0100 three times. I was told all three times that I would be contacted back within 24-48 hours (business days) regarding this safety issue. It has now been two weeks, and I have not received anything such as a returned phone call, email, etc. The vehicle is at my residence and available for any inspection or test, etc. I also have video of this problem. Again, the rear powered tailgate closes by itself, without warning. It closes VERY rapidly with force far greater than gravity alone.

STRUCTURE:BODY:HATCHBACK/LIFTGATE:SUPPORT DEVICE/STRUT

The lift gate has an automatic open feature like many vehicles. When you press the handle or use the remote control to open the rear lift gate, the gate opens all the way. After some time (5 - 30 seconds), the gate slams suddenly either to half way open, or slams completely shut on its own. This is especially dangerous when a person is under the gate getting something out of the trunk, and the heavy metal gate suddenly slams on to their head.

IN DECEMBER 2019 I WAS ON THE EXPRESSWAY AND THE TRAFFIC WAS BUMPER TO BUMPER. I WAS DRIVING BEHIND A LADY AND WHEN SHE STOPPED I WENT TO PUT MY FEET ON THE BRAKES AND THE BRAKES WENT TO THE FLOOR AND MY CAR HIT HER. I HAD MY CAR REPAIRED OF COURSE AND PAID MY DEDUCTIBLE.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? -The entire electrical system failed and the power steering, SRS, and ABS systems malfunctioned. Yes, it’s available for inspection. 2. How was your safety or the safety of others put at risk? -Last night around 9 pm CST we crank the car and started to drive, (no warning light at that time) and all of a sudden the car had a warning message to start the engine or the vehicle would turn off the engine although we were already driving. The car started to show all the lights and the brakes got harder to press while we were driving about 40 miles per hour. We couldn’t stop completely at the traffic light and the SRS light came on in the dashboard. After we got off the main road, the power steering locked up as we were trying to turn into a parking lot to safely park. Even after removing the key, the engine remained on and the headlights. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? -No, a dealer has not confirmed electrical problems for this specific VIN, although there has been a “blanket recall” on the models in this class. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -No, not to my knowledge. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -The battery light turned on around 9 am when I was driving my son to his appointment. Then the light went off. Later on in the day, I was able to drive approximately 30-40 miles before going home. In the evening, when driving to the grocery store, the battery light came back on and went off. After leaving grocery store, this is when the car malfunctioned. The ABS and SRS were prominent during the malfunction.

On 1/17/25, I was on my commute to my office when I noted a very strong and unpleasant odor. Thinking it was from a truck in front of me, I passed the truck, cracked my passenger window and continued the short distance to my office. After work, when I returned to my car, I noted a hole burned through my driver's side leather seat. I didn't make the connection to the odor from that morning until I arrived home and did some online research. It turns out that my front seat warmer had malfunctioned, burning all the way through the leather. This problem is well documented online in various forums in my year, make and model. In some cases I read about, driver's clothing burned. In one case I found, a child was burned. This is also a well documented problem that occurred in earlier models of Mercedes, resulting in a lawsuit and a recall. My car is currently at the dealer for repair of the faulty seat warmer, replacement of the burned foam cushion, and replacement of the leather seat cover. This could have been so much worse had I been earlier in my commute, or on a highway where I could not have pulled over. It seems like this problem should prompt a recall.

On January 01, 2025, I started my wife's car after adding coolant. I just want to warm it up since we did not use it in a couple of days. I activated the heated seat on the driver side where I was seated and was just looking at the dashboard. I felt something on back right side and thought that there was an insect bite. When I turned and look, I discovered a dime size red small flame and smoke on the seat and realized that it is possibly and part of the heated seat heating element that burned through the seat material and burned my sweater a little bit. I turned off the heated seat immediately and shut off the car and made sure the burning stop or was out. I was thankful that this happen while I was just warming out the car and stationary and that it did not happen while my wife was driving the car. This could have produced a dangerous situation, a bigger fire while driving and could have cause an accident. I called the Mercedes Benz service department which was possibly closed but I got a call back the following day and they said that there is no open recall on this vehicle on anything. I ask what is my option and the answer was to get it checked at the service dept. and that it would cost $351.00 just to find out what was wrong with it. I schedule service for Jan 14, 2025 at 3:30 pm. No police or insurance inspection was done. There has been no warning lamp or message to warn me of the problem. Jan 01, 2025 is the first time it happened. I told my wife not to use the heated seat and put a note on the car to inform anyone that will be in the car even though it is just my wife and I that drives the car.

POWER TRAIN

Vehicle is a 4 wheel drive SUV, having the Mercedes-Benz "4Matic" drivetrain, has it's Center Differential Planetary Gearset (With Integral Clutch Pack) in failure. Mercedes is clearly aware that this is a drivetrain component that fails prematurely as there is a Technical Service Bulletin (LI28.00-P-051499) that provides methodology for diagnosing the failure for 4Matic equipped vehicles from 2003 to 2016, specifically listing 83 different 4Matic equipped vehicles. Particular caution is called out as to special lubrication required prior to assembling the component into the drive train. Very likely that the root cause of the widespread failures was the part not being installed correctly. Though the failure evidences initially by front wheel vibrations and shuddering at low speed, it is a latent serious safety issue in that the component could fail catastrophically when stressed, i.e., hard acceleration when merging onto a highway, at best causing a sudden imbalance in front/rear propulsion resulting in an affected vehicle compromised in its steering, or at worst locking up front or rear wheels resulting in a spin out. Mercedes has replaced this equipment under warranty for an unknown number of vehicles, but refuses to acknowledge how widespread the problem is. Mercedes Customer Assistance says "no recall' so refuses to address the issue and flatly told me to take it up with the NHTSA. Public safety dictates that all affected vehicles need to be inspected for the failure and these defective components replaced as a recall.

UNKNOWN OR OTHER

Rear powered tailgate closes by itself. There is no warning. It closes VERY rapidly. This hit me in the head, but I am mostly concerned with others, such as elderly people and children. It could easily cause a concussion, or worse. I have contacted MBUSA advocacy at 1-800-222-0100 three times. I was told all three times that I would be contacted back within 24-48 hours (business days) regarding this safety issue. It has now been two weeks, and I have not received anything such as a returned phone call, email, etc. The vehicle is at my residence and available for any inspection or test, etc. I also have video of this problem. Again, the rear powered tailgate closes by itself, without warning. It closes VERY rapidly with force far greater than gravity alone.

VISIBILITY/WIPER

On 11/18/2023, while driving my GLK350 2014, I decided to open and later close the sunroof. As I closed the sunroof, I heard a distinct cracking sound, which caught my attention. Initially, I was unsure of the source of the sound and continued driving. It wasn't until I arrived home that I made a shocking discovery - the front black stationary window panel, located just above the windshield, had shattered unexpectedly. Prior to this incident, I had meticulously cared for my car, ensuring it was regularly maintained and kept in excellent condition. There were no visible cracks or signs of damage on the front black stationary window panel. I even hand-washed the vehicle earlier that day and inspected the panel, confirming its integrity. I had a clear view of the area around the car while I was on a ladder, ruling out the possibility of any rocks or debris causing the breakage. My adult daughter was present in the car with me as a witness to this unfortunate event. We were both astonished by the sudden and unexplained shattering of the window panel. Given the circumstances, it became evident that there is a significant safety concern regarding the GLK350 2014 model's front black stationary window panel. The shattered panel poses serious risks to the safety of both the driver and passengers. These risks include compromised structural integrity, the potential for harmful glass projectiles, and impaired visibility that could lead to accidents or hazardous driving situations. To address these urgent safety concerns, I have written this letter to request an immediate safety recall for all GLK350 2014 vehicles. It is our collective responsibility to ensure the safety and well-being of all drivers and passengers who rely on your esteemed automobile brand. Please consider the gravity of this situation and take swift action to rectify

STRUCTURE:BODY:HATCHBACK/LIFTGATE:SUPPORT DEVICE/STRUT

The lift gate has an automatic open feature like many vehicles. When you press the handle or use the remote control to open the rear lift gate, the gate opens all the way. After some time (5 - 30 seconds), the gate slams suddenly either to half way open, or slams completely shut on its own. This is especially dangerous when a person is under the gate getting something out of the trunk, and the heavy metal gate suddenly slams on to their head.
