Mercedes-Benz is recalling certain accessory all-season floor mats sold for use in model year 2012 and 2013 Mercedes-Benz ML-Class vehicles. This all-season floor mat may not fully conform to the contour of the vehicle's floor plan as intended. Clearance between the mat and the gas pedal may be reduced, possibly allowing the pedal to become trapped.
Risk and remedy
Risk
This interference could prevent the gas pedal from retracting and the vehicle may not decelerate as expected when the driver lifts their foot from the gas pedal, which could increase the risk of a crash. Should the pedal become trapped, steady application of the brakes will allow the vehicle to be brought to a stop.
Remedy
Mercedes-Benz will notify owners, and dealers will replace the floor mats free of charge. Until replacement mats become available, consumers are advised to remove their floor mats from the vehicle. The safety recall began on December 21, 2012. Only vehicles equipped with the accessory floor mats are affected. Owners may contact Mercedes-Benz for more information at 1-800-367-6372.

My name is [XXX] My vehicle cut off on me 3 times twice while stationary and once at an intersection. Found oil in engine control module due to failed cam position sensors. Oil has traveled through the engine harness to ECM causing oil to get into module and cause it to shut down but it did start back up. This is very dangerous and could cause serious injury to someone.

Vehicle stalled without warning, and I was advised by a mechanic that the fuel pump control unit was reporting a fault through the onboard diagnostics port and the check engine light on the dashboard. It was necessary to replace the fuel pump control unit as the defect was intermittent and subject to occur at any time the vehicle was being driven. There is no available solution save the replacement. I had the fuel pump control unit replaced at my cost and after replacing it found information concerning the NHTSA recall campaign online. The defective fuel pump control unit was discarded upon replacement and is not available for inspection. I believe the failure of this fuel pump control unit is a direct result of the recall not being complied with. I believe the manufacturer; Mercedes Benz USA is responsible for my costs expended in repairing this defect under the recall campaign because they did not notify me of the recall. I purchased this vehicle from an authorized Mercedes Benz USA dealer, my personal contact information is a matter of record of the sale, and I believe Mercedes Benz USA had a duty to contact me concerning the NHTSA recall campaign #2023010002 concerning this vehicle.
- Forward collision avoidance › Adaptive cruise control · Lane departure › Blind spot detection · Seat belts
The driver's seat belt is locked and the retractor is not working without any reason. The front adaptive cruise control radar is also not working, along with the crucial blind spot sensor. Because of this, the vehicle cruise control (even without adaptive mode) is not working at all. This is a big safety issue and it is illegal to even drive this car without the seat belt working.

My wife was driving home from shopping and noticed an accumulation of dust on the rear window. She used the rear wiper to clean it but it came right back, she repeated twice and gave up. Approx 3-4 miles later she heard a POP and red lights came on the dash, when she pulled over ASAP in a safe spot smoke started coming from under the hood. She shut the engine off and tried to exit the car to find the hood release under the dash but there was fire coming out from under the car. She closed the door, grabbed her purse and cell phone and got out quickly as possible, burning her ankle and singing her long skirt. She got approx 50 feet away, looked back and the entire car was ablaze, centered mid vehicle, as well as 4-5 spot fires along the road she had just traveled. Previous to the POP the car was driving, steering, and braking normally, no warning lights of any kind. Visiting the site the next day revealed sound deadening/insulation material in and along side the roadway for 2-300 yards as well as dripping molten aluminum, corresponding to the area traveled after she first heard the POP. The vehicle had extensive repairs of cascading failing emissions system components only 7-9 months earlier, culminating with 42 days at Mercedes San Rafael where one component after another failed and was replaced. Myself and all knowledgeable persons i talk to assume it was an overheated catalytic converter that caused the problem. So far Mercedes has not been aggressive i trying to determine the cause. I've hired a forensic company and a joint inspection is pending. Cal Fire was able to contain the vegetation fire started by the vehicle at 85 acres, known as the Veteran's Fire-Igo as it occurred near the Veteran's Cemetery, using multiple fire engines, bulldozers, helicopters and a boride bomber. We are thankful she was alone in the car at the time without grandchildren buckled into car seats in the back or the results surely would have been much more tragic.

My indicators stopped working a month prior to accident, then they started working again. On March 10th the issue happened again where I turned my signal on and no light appeared and no light on the dash with the indicator sound either. Boom, I had sideswipe someone on a major road causing an accident. NHTSA needs to do something about this because corporate won’t do anything!

Steering column module is intermittently not working as intended, therefore the blinkers will sometimes not work causing it to be a safety concern if I can not signal where I am going. When looking this issue up online I have seen numerous different forums and posts where people have had the same issue. When I took my vehicle to the dealership they had told me that this is very common with the vehicle I have and they do the fix all of the time, just for the issue to happen yet again later down the road.

The contact turned off and restarted the vehicle. The contact drove the vehicle for a short distance and the failure reoccurred. The vehicle lost motive power and failed to restart. The vehicle was towed to an independent mechanic where the contact was informed of water entering the spare tire wheel well in the trunk of the vehicle. The contact was advised that the spare tire wheel well, was filled with water. The contact was advised to take the vehicle to the dealer for assistance. Per the dealer's records, the work associated with NHTSA campaign #22V955000 and MBUSA recall #2023010002 had been completed in March 2023. However, that recall failed to address the source of the issue where water was improperly entering the spare tire wheel well. The dealer did not maintain any records as to the status of the fuel pump or signs of water entry when the recall was completed. The manufacturer refused to cover this repair under the associated recall. The failure mileage was approximately 141,000.

Cuando enciendo mi guagua hace un ruido muy fuerte y SE siente como si SE va a apagar. El motor SE puede romper en cualquier momento. Si SE ha llevado a diferentes talleres para confirmar el ruido y me refieren que son mas de 80 guaguas que han visitado su taller con el mismo problema. No presenta ninguna advertencia cuando aparecio por primera vez. En el taller me dicen que SE debe cambiar el motor por que son los motor stroker y eso puede causar un feo accidente. when I turn on my bus it makes a very loud noise and it feels like it's going to turn off. The engine can break at any time. If it has been taken to different workshops to confirm the noise and they tell me that there are more than 80 buses that have visited their workshop with the same problem. It does not present any warning when it first appeared. In the workshop they tell me that the engine must be changed because they are the stroker engines and that can cause an ugly accident.

Due to water in the spare wheel well, (Recall ID:22V955) our fuel module and fuel pump went out. While driving in traffic on I-5 our car stalled then stopped which put us at risk of a crash.The first time (July 2022) It was repaired by Cooper's Auto Repair), After the 2nd time it failed again in Aug 2022, once again as we were driving, our mechanic at (Boyle's Foreign Car Repair) Aug 2022 & Dec 2022 (replace) decided to do an inspection of the whole car to see why this was happening, upon inspection he found water in the spare wheel well, He pulled out the plug to stop accumulation. 2 months later (Feb 2023 )we received the recall letter. In the letter it states that MBUSA would reimburse repairs performed prior to the recall. MBUSA is now refusing to reimburse for replacement but also refusing to find and fix where the water in entering. We reside in a very wet part of the country and see this as a continuing issue. There also is condensation in the back tail lights, which was not there until this issue started occurring. The car was previously in S Cal so there was no issue with water accumulation until it was moved to the rainy Pacific NW. We are fearful of using this car during very wet times as we do not know if this (failure of pump/module) will occur as well as condensation and water being in the back tail lights possibly resulting in the car stopping during it being driven. Therefore putting our lives in potential danger of an accident.

The steering column does not operate properly. The column no longer adjusts positions and more importantly, the turn signals work ad-hoc. When you start the vehicle, the turn signals tend to operate properly; however, after driving for approximately 15 minutes, the turn signals operate sporadically. THIS IS A SAFETY CONCERN as it's impossible to know when the turn signal will operate correctly or not, thus creating a hazard to me and others on the road. It is my understanding from investigating this online that this is a systemic issue with this model and not unique to my vehicle (just google "2012 Mercedes ml350 turn signal problems"). I discussed this with Mercedes Benz USA and they told me that the only way to resolve this issue is to replace the steering column (part #: 166-460-62-00) at the cost of $3,373.81. I hope that the NHTSA investigates this further as Mercedes-Benz has decided to ignore this safety issue that may cause harm or death. Sincerely, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The following has been happening over the last 2 - 3 yrs. Also confirmed with other customers on MB world blog site. After traveling in the car for 5-15 minutes, and sooner if connected to cell phone via bluetooth, the indicators stop working. This leads to deactivation of the blind spot assist as well. The problem is temporarily resolved after switching the vehicle off and then on again, only to recur after driving it again for 10-15minutes, and earlier if attached to iPhone via Bluetooth. The blind spot assist is then permanently inactivated. 2 Mercedes dealerships in 2 separate states where I took the vehicle could not even identify a problem, let alone resolve it. When I called MBUSA, they claimed ignorance to the issue and told me to repair or change the vehicle myself. Since this is an issue with multiple vehicles, a recall needs to be issued for this model. It’s unknown how many collisions can be attributed to this since the problem has not been acknowledged by Mercedes’. The problem has occurred almost everyday over the last 3 years. I have narrowly missed being involved in collisions because of the inactivation of blind spot assist and changing lanes. I have almost been rear ended a bunch of times because of the indicators getting inactivated. All this has happened with my family traveling me with. Please lets not wait for loss of life before a recall is initiated. thank you.

- 11010907Complaint The flap of the reversing camera opens and closes by itself during forward travel. This happens several times during the trip. The customer notices the sound of opening and closing. No camera image is displayed in the head unit. The reversing camera or the 360 system functions normally when activated manually or by engaging drive range "R". This behavior occurs again during each driving cycle. Cause This is not a malfunction, but an intended system behavior: Calibration of the reversing camera is in progress. For this, the cover on the camera is opened for max. 5 cumulative minutes in forward travel. The calibration can be performed if the vehicle speed is < 35 km/h and the steering wheel angle is < 10 (for early vehicles from MFA2 facelift model series such as A-Class, CLA, etc., the 35 km/h (~22 MPH) opening limit may only be reached after the SCN coding is replaced). If the speed of 35 km/h (~22 MPH) is exceeded, the camera retracts and the calibration is therefore aborted. The sequence is started again once the speed returns to the range of 18 km/h (~11 MPH). Remedy Complete the calibration successfully. For this, the vehicle must be driven forwards for a certain time (usually significantly less than one minute) at a speed < 35 km/h (~22 MPH) and a steering wheel angle < 10. This should occur during daylight and without a vehicle following too closely (the camera must be able to see the asphalt). When calibration is successful, the camera flap closes automatically at an unchanged speed. For the rest of the driving cycle, the camera now only opens if the customer requests this, for example by applying the reverse gear. When starting a new driving cycle (ignition change), another calibration is required. The customer can generally perform calibration at the first attempt when a speed in the range between 15 km/h (~9 MPH) and 35 km/h (~22 MPH) is briefly maintained and can therefore play a significant role in reducing the actuation frequency and therefore also the noticeability of the noise to a minimum. In the case of early MFA2 facelift vehicles (A-Class, CLA, etc.), the parking control unit may have to be SCN-coded again to have the complete speed window available for the calibration.
- 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.
- 11010755Complaint After a control unit replacement of "N112/9 - control unit for telematics services (HERMES)" or the "N112/2 - control unit for telematics services (RAMSES)", the Digital Extras (previously Mercedes me) cannot be activated. The DTC B15CE00 is active or active+saved. In vehicles with "N112/9 - control unit for telematics services (HERMES)": The message "SOS - service not activated" permanently lights up in the instrument cluster AND the actual value "Error when replacing certificate (CEP.36)" is displayed in the actual values for the activation status under "Registration status" (see picture 1). In the control unit log of the "N112/9 - control unit for telematics services (HERMES)", the registration error "CEP Invalid VIN/UniqueID combination" is displayed. In vehicles with "N112/2 - control unit for telematics services (RAMSES)": The actual value "Error when replacing certificate (CEP.36)" is displayed in the actual values for the activation status under "Registration status" (see picture 1). In the control unit log of the "N112/2 - control unit for telematics services (RAMSES)", the registration error "CEP_ VIN_UNIQUEID_INVALID" is displayed. The emergency call is not impaired. Cause In the event of a control unit replacement, sporadic problems in the back end could result in data from the new control unit not being updated in the back end system. Remedy Please create a TIPS case. In some cases, the problem rectifies itself on its own after a little while.
- 11010750Complaint Creaking noise, in irregular sequence when driving slowly in combination with slight steering movements. Sound file attached for comparison. NOTE: Steering functionality is not affected. For 192 and 232: Only affects vehicles up to FIN vehicle identification end number. If vehicle falls outside of FIN range, create a TIPS case. Model series 192: xxx xxx xx 002 876 Model series 232: xxx xxx xx 022 312 Cause Contact area between wheel bearing and steering knuckle. Remedy 1. Perform Operation A and evaluate by testing vehicle. 2. If noise is still present, perform Operation A again. 3. If noise is still present after re-testing, perform Operation B. Operation A: 1. Clean contact surfaces of wheel bearing and steering knuckle with brake cleaner (see areas marked blue in pictures "2.jpg" and "3.jpg"). NOTE: The front area of the wheel bearing and the seals must not come into contact with the cleaner, otherwise, the sealing rings will be damaged. 2. Clean threads of wheel bearing mounting. 3.

- 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
- 11007790Complaint Headlamps fogged or droplets forming. Cause Due to the housing cover with pressure compensation diaphragm, the headlamps are a "closed system". This means that the headlamps are protected against acid gases, dirt and exhaust gas. However, moisture can still enter from two sources. Through absorption and desorption (the commonest cause) or through permeation. Moisture is either absorbed by the plastic material and, when the light source is switched on, it is released from the plastic by desorption, or the moisture penetrates through the plastic materials of the headlamp from outside (permeation). 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 headlamps 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 existing service cover with diaphragm (Picture_01 (1)). 2. Insert desiccant packs (Picture_01 (2)) into new service covers with diaphragm and seal with protective grille and bolt down (Picture_01 (3)). Note: One desiccant pack is required for each small service cover, and two desiccant packs are required for each large service cover. 3. Stick the supplied diaphragm onto the new service cover and attach at the headlamp. Note: The bonding surface must be clean and dry. 4. If the headlamp housing has an additional 2nd diaphragm, this must be covered over with masking tape. Note: The bonding surface must be clean and dry. 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_02). 2. The new transparent diaphragm must be correctly bonded (Picture_03). 3. Check headlamp housing for any external damage.

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
