  I was driving and the reduce braking light came on. I pulled over stopped my vehicle because it stated that I needed to do so, restarted the vehicle and tried to make it home. I began to loose control of the steering and even though I was pushing the brake pedal to stop, the pedal went to the floor. I was in rush traffic and so scared that I would hurt someone or myself. I recently had my brakes and rotors replaced, months in advance. I barely made it home and since then I have tried to take my vehicle to the shop but in doing so the same problem arose. again, I was frighten to put it on the road I placed it back in the garage. please help. I am not understanding why I am having these problems. I brought the car in september of 2013 and this IS the only major issue I have had. I love my car. I also read that in 2006 some type of braking system was discontinued and that there was a recall on the sbc pump.

  I was entering onto a highway (100). at the point of the highway I was entering(from cty rd 81) it opens the highway to a 3RD lane on the right side of the highway. At the same place it opens the highway up, there IS an immediate exit(42nd ave). As I am accelerating to highway speeds, just prior to the new lane availability that drivers must enter to get off on 42ND, my car starts chiming and there's a red warning on my dash that states "stop, reduced braking power. Depress brake fully." or something quite similar. There IS no shoulder, I'm going like 10 mph, terrified. People are honking and trying to get over to get off on 42ND ave in a lane where I'm going 10 mph and they were at a speed of approx 60 mph(posted hwy speed). As I limp my car past this exit to a shoulder I then attempt to brake and have no braking power. I eventually rolled to a stop. Turned my vehicle off to determine my next move. I turned the vehicle back on to see what exactly the warning light said- there was nothing there. Tested my brakes a little on the shoulder and they were fine. I was able to drive the rest of the way to my destinations without any problems. This has since occurred a couple more times. Through a trip to the mechanic and thorough research it IS determined the problem lies in my sensotronic brake pump. This IS a pump that mercedes warrantied for 10 years due to this issue. This will occur to all other drivers of this vehicle that haven't had this part replaced. I never knew of the safety issue with the braking system until this problem occurred. I would have replaced it years ago (under warranty at the time of replacement). My children's lives, my life, and the lives of all the drivers on the highway that morning were placed at severe risk. This should have been recalled and still should for all of the other unsuspecting drivers- for their safety and others on the road.

I ask the store to exchange because it can cause dangerous accident but they said we can exchange as long as your tire IS not totally flat. I don't know which institution of government can impose this business to save the client for what they paying for. I can show photo to my tire as a prove and if this front tire can flat in high way , it will course big accident. It IS not fair to pay 1300$ tire with extra warranty and the store tire give a respond like" die first and after get reimbursement". Thank you

  I began smelling fuel in the cabin of my car and contacted the mercedes benz dealership in my area, westminster, co. the woman I spoke with told me that she was unaware of any issues, but that she would look into it and get back to me. I never heard back. the smell was getting worse and after 3 weeks, I could not drive with my windows closed, gagged when I got into the car and smelled like fuel upon exiting the car. I called mercedes benz again and asked if I could bring the car in. I was told I could and that there was a warranty extension for faulty fuel tanks. the fuel tank was allegedly repaired, but upon returning the car to me, the car still smelled like fuel. I thought the smell might dissipate over a few days, but it did not, seemed to get worse again, so I took the car back in. I was told by the service rep that the fuel had leaked into the underlayment of the car and was deteriorating the floor boards. I was also told to "not smoke in the car" by the service rep. mercedes benz IS now refusing to repair this damage caused by the faulty part. They feel that the car IS "safe" even though I was told not to smoke in it. I don't smoke, but if there IS an electrical spark or I get in an accident, I don't want the car to blow up.

• 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.
• 11008091Complaint During a phone call, the called party has difficulty understanding/cannot understand the driver, or interference/background noises are audible to the called party during a call. It becomes increasingly difficult to understand as the speed rises. Cause A. Seating of the microphones in the headliner. Side edges are covered by the textile cover (see picture "1") B. Assembly of microphones (B25/20 or B25/21) in the headliner. C. Dirt inside the microphone housing Remedy 1. Press finger on rear of microphone (on adhesive tape) 2. Remove microphone cap from the front 3. Eliminate protruding material residues of the microphone cutout at the headliner, e.g. with a soldering iron. The microphone must be seated in the headliner as shown in picture "2". 4. Push microphone from behind until it is firmly pressed into the headliner 5. Maintain pressure and press/clip cap into microphone from the front. Note: The cover cap must be clearly heard and felt to engage. 6. This procedure must be carried out on both microphones (B25/20 and B25/21) Note: It is recommended to replace the cover caps. The non-woven cloth in the cover cap protects the microphone from soiling and must not be removed.

• 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.

• 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).
