- Fuel/propulsion system
The fuel tank has a leak from a defect in the plastic, and my local Mercedes dealership is unwilling to honor the Warranty Coverage Extension that covered fuel tank components to replace the fuel tank.

While driving the vechile lowered and I noticed a puddle while idle
- Power train
Defective internal speed sensor does not send signal to tcm(transmission control module) causing loss of power while moving. The only way to get car going again IS to shut off car and restart hoping it will reset. If this were to happen in construction zone with nowhere to pull over, may be deadly.

Driving highway speeds and suddenly vehicle jerked and losses all power. Engine revs but doesn't move. This can be a very dangerous situation. Transmission went into 'limp' mode and check engine light lit. Many other mercedes owners reporting same problem with the 722.9 transmission valvebody, conductor plate, and/or tcm. this should be investigated as countless other people are reporting this same issue for several years now.

I am referencing action # pe12001. After each of my last two fuel filllings, the car IS emitting a very strong smell of gasoline from the back seat & trunk compartment. I park my car in my garage and the smell IS strong enough that I can smell it in my home. I am extremely fearful that there will be a fire. I do not desire to park my car outside, but I believe the car IS unsafe to keep in garage. I have lost confidence in my car fearing that even driving it around town could pose a danger to me and my passengers.

Note that the vehicle on has 43,733 miles - cabin interior strong live fuel fumes - constant gas fumes on the inside of the car cabin. note that the car was stationary at my residence parking. I did not know where were the fumes coming from at the time. Got a headache just for the moment I was trying to determined where were the fumes coming from. This IS currently for all drivers and owners a very hazardous dangerous condition to all extremes, very high risk from ignition from static or electrical, due to wire hardness in the area. Vehicle was towed and took it to mercedes benz dealer and found the following: leakage in fuel system. replaced fuel tank fuel tank drain/fill observed accident prevention regulation "12 WL08" fuel tank and fuel for storagebring observe accident prevention regulation "12 WL08" performed by mercedes-benz of new orleans. fuel tank leaking in the interior was found / was drained & refilled and fuel tank replaced. This was cover under a new settlement with mercedes benz and nhtsa. I think that this should have been a recall when it relates to safety factors.

My husband and I purchased the 2007 cls550 about september 2015. We noticed when filling the vehicle with gas, we would have gas fumes in the vehicle specifically on the passenger side rear inside and outside. The fumes were light and would dissipate once the vehicle was driven to reduce the amount of gas in the tank to about three-quarters tank. Last week we filled the tank and the small IS now stronger and has yet to dissipate although we have a quarter tank of gas remaining. I checked for any recalls on this since we have no knowledge of the vehicle having been in any accidents, but find we do not. This online search did not reveal any recalls for the gas fumes, but I noted there are multiple complaints about the same problem for this year, make and model of vehicle. Have any people died from this, any fires, accidents as a result? We have not yet, but will be taking our vehicle in for evaluation of the problem and would be able to provide documentation of the results in the future. Given the name, I am surprised mercedes IS not stepping up here! *tr

Every time I fill up my tank with gasoline, once I park in the garage, the garage IS filled with strong gas fumes from my car. I checked for leaks under the car and found nothing. I have to raise the garage door to let the fumes out, due to getting lightheaded from the fumes. The fumes remain with the car for 7-10 days. This has been going on for the past four years. This problem IS a danger to my family's health!!!! Surely, there IS a recall on this problem! 2ND issue: I turned my car off and the fan kept running. I noticed that the fan was so loud that it sounded like it was about to blow up. Black smoke came from under the hood. I went on into the building to my meeting for an hour. When I came back outside, the fan was still going and still loud. This had never happened in the five years that I had the car. The car would not start. I had to call someone to boost it off to start. I then went to the shop to check to see if I had battery or starter problems. No problems found in either. This has happened twice since then. I am afraid that the car will catch fire with me in it or my family or friends. 3RD issue I was driving along and the dashboard read out in red to stop the car ..vehicle IS too low... When stopped, I noticed that the passenger side of the car was low and the driver side IS raised high. I have to sit there for a few minutes until the red lights went out. This happens often. 4TH tire pressure light stays on. I took it to check on pressure, it was ok. I did not need new tires either. The yellow light stays on and this week the red light popped on and will not go off. 5TH the check engine light stays on and mechanic can not find the problem. 6TH steering system loud popping noise when I back up or turn steering wheel. It used to be random but now it IS every time I drive the car.

There IS a fuel leaking into the backseat of my 2007 mercedes benz CLS 550 I began noticing the smell in my car a few months ago and I finally decided to remove the back seat, under the back seat lies the fuel tank and a fuel filter module which IS leaking and creating a small pool of fuel and a fuel scent in my car. Incidentally mercedes had a recall on the mercedes benz 2006 CLS (voluntary emissions recall campaign #2008-020001) my car IS a mercedes benz 2007 CLS with the exact same problem. I would like to file this complaint and ask that you help me in getting mercedes benz to take responsibility for this faulty fuel filter module and initiate a recall to repair this problem. This problem has been documented extensively on many mercedes benz forums http://www.mbca.org/forum/gas-leak-sending-unit this issue creates an immediate hazard to me, my family and other drivers. I ask that you take quick action in contacting mercedes benz demanding they make amends to this issue before someone gets seriously injured.

Upon smelling gasoline when the auto in question was filled, we were directed my mercedes dealership on west sahara in the city of las vegas in the state of nevada. The owner replaced the gas cap. The auto in question continued to smell of gasoline off and on. In september of 2014 the auto displayed a signal at the engine needed to be looked at. The auto was taken back to mercedes on west sahara and the owner was informed that there was a fuel tank leak. Due to the quote of $3500 to fix the issue, the auto was taken to g&g auto and authorized mercedes repair shop in las vegas. The lead mechanic confirmed the fuel tank leak and showed the owner how the gas pooled on top of the tank which IS just under the back seat. obviously a huge danger. the owner of g&g autoshop informed the owner that this IS a very common problem and alerted us to the documentation on the internet regarding class action law suits. The owner contacted mercedes head quarters in new york city and well as the general manger of the west sahara service center. The owner was told that the car was no longer under warranty and they would not repair the car unless paid. the car was ultimately repaired at g&g auto shop. *tr

I started to notice a strong smell of gasoline inside and around my car. This occurred soon after filling up my gas tank. I looked around my car to see if I could detect any leaking, or puddling underneath my car but didn't notice many drips. The strength of the smell decreased as I drove and as the gas tank level decreased. The next time I filled up my gas tank the smell came back and was very strong. Anyone who rode in the car with me including my wife and our son, would comment on the smell. After doing some research I realized that many others have had this problem, and that there IS even a class action suit open for this same type of defect in another year and model mercedes. I called to file a claim with mercedes USA, and they said that this IS not something that they would cover the repairs on. I can't believe that mercedes USA wouldn't cover defect repairs for an issue many people have had, especially with the health and safety risks associated with gasoline leaking from the gas tank, as well as the gasoline fumes leaking into the cabin of the car. I hope there are enough people that voice their similar experience so that a government investigation can bring out the facts of this obvious defective issue. Long term effects of gasoline fume inhalation are suspect to cause cancer. *tr

I've had this vehicle for years. Each time I fillup, there IS a very intoxicating smell of fuel inside and outside the vehicle. I was reading up on it and seems to be a common problem. This IS a true health hazard as you cannot breathe right because of the fumes. Not to mention the chances of it catching fire. *tr

I filled my car up sunday and parked it in the garage, the following morning there was a strong fuel smell that permeated the garage and all around the car. I looked for leaks found none. The smell was coming from under the seat on the drivers side rear. I reviewed some online forums and noticed this seems to be a common occurence with these vehicles. This IS very dangerous and a saftey hazard. *tr

When I fill up my car with gas there IS a strong gas odor around the left back seat on the interior and around the left rear wheel on the outside. After further investigation I found gas leaking around the left sending unit / pump. This IS a serious design flaw as the sending unit / pump IS made of plastic and servers a structural member to suspend the unit in place. The presence of gas fumes in the interior IS a fire and human health hazard and the gas fumes on the outside of the car IS at minimum a fire hazard. This appears to be a common defect on mercedes CLS and e-class between 2004 - 2008. Thanks for your assistance in this matter. *tr

I had filled my car up with gas the night before I noticed the incident. The next day when I went inside of my vehicle it had spelled horribly of gas, so bad I was getting light headed from the fumes and had to keep the window's open to air out. But the smell has remained for a week now.. I located the source of the smell coming from the rear seat on the drivers side, I removed the rear seat cushion and it smells as if it was doused with fuel. Even with the seat removed the smell remains. I proceeded to look online about common issues for this problem, I noticed a recall on the fuel sender unit for previous years but not the 2007 model of my vehicle. I have seen many people complain of this exact issue for the 2007 model. I called the mercedes dealer about the issue and they say there IS no recall for my model except for the camshaft selenoid. this IS a highly important issue that should be looked into, I have my children in the car at times. I have made an appointment with the dealer to further look into my problem but I think this should be investigated and reported as a recall since others have the same issue.

Check engine light came on. Reads p0456 evap small leak detected. After filling gas tank full or anything over 3/4 full. Strong gas fumes smell inside and outside of car. Checked top of fuel pump under rear driver's seat. Fuel was puddled on top of this unit. (I have pictures if needed) replaced fuel pump seal ring and gas cap with new parts. Problem has came back with more check engine codes and strong gas smell/fumes inside car. I believe e-class 03-06 have same safety issues, and hope my 07 cls550 will be included in a possible recall, etc. As I believe the cars use same parts/platform. Refer to: nhtsa# pe12001. *Tr

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
