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.

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).

I was driving in highway with speed of 60 mph and suddenly the driver side window dropped down and due to sudden air coming insude, my car was shifted and I drove to nearest exit and no matter how hard I tried, I was unable to pullup the window and took it to mechanic and he noted he has seen this several times before and the regulator suddenly malfunctions. The cost IS estimated $1,000 to fix it. I would like to warn that I am a highly experienced driver, if this incident would have happened to a driver with less experience, it could be very dangerous. My insurance decuctible is $2000 and cost to fix it $1000

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.

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.

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.

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!!!!

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.

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.

- 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…
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.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
Service bulletins
Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.
- 11010818Complaint Transmission control unit Y3/8n4 (fully integrated transmission control unit (VGS)) not listed in quick test and/or no communication possible with VGS. Cause Transmission control unit Y3/8n4 Remedy It is important that LI54.15-P-057373 is processed before replacing any component parts (transmission 722.9). After processing and complying with the above documents, perform a reset on the transmission control unit Y3/8n4 (VGS) (ignition reset), check that the transmission connector is seated correctly and inspect the PINs for concerns. If communication with the VGS cannot be established afterwards, the component part 'electrohydraulic controller unit (EHS)' must be replaced, as it is not possible to transfer the valve characteristics under the above-mentioned conditions. Installation of a VGS repair kit is not permitted in this case.
- 11009122Complaint Washer fluid system leaks Cause Various possible causes: 1. Washer fluid reservoir itself. 2. Seal on washer fluid pump/washer fluid reservoir. 3. Washer fluid pump. 3.1. Distributor housing leaks. 3.2. Pump fitting leaks. 3.3. Washer fluid hose cannot be snapped into place on pump fitting. 3.4. Washer fluid hose will not stay on pump fitting, although connector OK. 4. Washer fluid line. 4.1 Connector will not stay on pump fitting because it is broken. 4.2 Sealing ring in connector missing. 4.3 Sealing ring in connector fitted, but deformed and therefore leaks. 4.4 Damage to washer line by animal. 5. Seal on heating washer fluid reservoir/washer fluid reservoir. Remedy Replace defective component parts only. Do not replace any adjacent component parts that are intact. Note: Repair kits for washer line hoses do exist to allow patches for line damage.
- 11008323Complaint Headlamps fogged or droplets forming. Cause Due to its outlet openings, the headlamp is an "open system". This means that acidic gases, moisture, dirt and exhaust gases can penetrate into the headlamp. This can lead to the formation of condensation on the lens of the headlamp. The headlamps comply with all applicable US standards and regulations. Remedy Check housing cover of lamp unit for natural fogging or condensation as per LI82.10-P-078301. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. Note: Order service covers and desiccant packs based on the validity description. 1. Remove headlamps. 2. Remove all grommets from outlet openings. 3. Seal vent openings with sealing profile. Important: All openings must be sealed carefully for the pressure compensation diaphragm to work properly! 4. Remove existing service cover. 5. Place desiccant packs into the new service covers and bolt down (Picture_01). 6. Glue the new diaphragm onto the intended surface at the service cover (Picture_02). Note: The bonding surface must be clean and dry. 7. Attach service cover with desiccant pack at headlamp. 8. Install headlamp. To ensure that the desiccant pack (absorption) acts effectively, the headlamp has to be air-sealed. Observe or check the following points for this: 1. Seals at the central connector must all be present and correctly fitted (Picture_03). 2. The new transparent diaphragm must be correctly bonded (Picture_04). 3. Check headlamp housing for any external damage.

- 11007974Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamps or Front Fog Lamps Leaking or Fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: Connect test adapter to pressure tester. (Figure 1) Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (picture 3). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is not leaky and the problem is down to natural physical fogging. If a pressure drop of more than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Note: Desiccant packs can be installed for headlamps that are not leaky. See: LI82.10-P-064766 Fogged headlamp, desiccant pack installed - open ventilation system LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system
- 11007753Complaint Headlamp or front fog lamp leaky or fogged Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. Headlamps comply with all applicable standards. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps and LED rear lamps: 1. Drive vehicle into workshop (temperature higher than +18 C/+64.4 F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in the formation of condensation, check the headlamp for a defect. (See Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Remedy 2 A Damaged headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness in accordance with LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. Open ventilation system: LI82.10-P-064766. Closed ventilation system LI82.10-P-078304
- 11005294Complaint Rear lamps fogged up/not leaktight. Cause Fogging of the rear lamps is a natural phenomenon, which can occur under certain climatic conditions. This does not lead to any technical impairment of the rear lamps. Remedy Rear lamp: Remedy 1: Clearing fogged/condensed rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4 F) Note: Do not wash the vehicle or subject it to high-pressure cleaning before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the trunk. 4. Switch on the exterior lighting. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation -> a significant reduction in the formation of condensation must be clearly recognizable (defogging progress).
