Other Fuel System Tank Assembly Problems of Mercedes Benz CLK350

When I fill my car up I can smell gas in my garage. Once I drive it for a while and it gets below a half tank or so I don't smell the gas anymore. I am worried that the gas smell in the garage made some fumes into my house and this is a safety issue. I see some models of mercedes have been recalled for this reason. I would like mercedes to recall and repair this at no charge to me. Apparently mercedes covers model year 2003 to 2009 on the e class in 2006 to 2011 on the cls class. I am having the exact same issue.

Bought the vehicle at 42k miles 3 years and it smells fuel inside the vehicle and the garage for a couple of days on each tank fill up. It smells so bad I have leave the garage door open sometimes so that my house does not catch fire along the vehicle. Searched online a lot of owners of the same vehicle have the same complaint.

Purchased from private individual with mileage 43,000. Filled up the gas tank on two occasions. After each occasion, placed car in garage afterward and closed garage door. The smell of raw gas was overwhelming as soon as garage door was shut. Due to the overwhelming smell and safety concern, car was parked in driveway. No leaks on garage floor were found. Car parked in garage the next day without the smell of raw gas.

When I fill the gas tank, there is a very steong smell of fuel inside and outside of the car. The smell IA there util at least half the tank is used. The same problem has been with "e" series. Mb issued a recall. However, the dealership tells me there is no recall for 2007 Clk350 eventhough same parts are used to deliver the fuel.

Routine maintenance identified gasoline leaking from fuel tank's "fuel sender". Small crack in plastic fuel sender at point where fuel hose attached to sender allowed gasoline to accumulate over time in area surrounding sender and then travel to underside of car in an area immediately adjacent to exhaust system. At time leak was discovered approx 1/4 cup of fuel had accumulated. Had problem not been discovered a car fire was inevitable.

Strong odor of gasoline, mainly after refueling and then continuing when driving and when stationary. Mechanic assessed that fuel is leaking from the upper part of the gas tank and the fuel components.

On December 9, 2016 I took my 2006 mercedes-benz Clk350 to the dealership because of a strong odor of gasoline coming from the back seat area. The dealership found the fuel smell was coming from the left rear fuel sending unit leaking. Although I was aware of the extended warranty agreement between mercedes-benz and NHTSA covering leaking gas tank components on mercedes-benz cars, I was informed by the dealership that the agreement did not include gas tank leaks on my clk vehicle, despite the fact that the same gas tank leak was covered on other mercedes-benz vehicles. Thus, I had to pay for the expensive repair out of pocket. I am requesting that NHTSA amend your prior agreement with mercedes-benz to include additional models such as my 2006 clk 350 which have developed similar leaks in their fuel tank components.

After fueling up there is a strong fuel odor until the tank is about 3/4 full. The car has only 54k miles.

The contact owns a 2006 Mercedes Benz Clk350. The contact stated there was a persistent odor of fuel coming from the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed that the fuel tank was fractured at the sealing point and was leaking fuel . The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 72,000 and the current mileage was 76,000.

Similar to the gas fumes leak experienced on the e class, our 2006 clk class suddenly emitted gas fumes originating from the gas tank after the tank was filled with gas.

Driving down the road at a slow speed and the car just quits. Sometimes it will start itself back up and sometimes I have to pull off to the side of the road to turn ignition off and then on again. The car will just quit at highway speeds and after some quick thinking and realizing what just happened the only thing to do is drift to the berm of the road with no pwr steering or brakes. There are also times when I start the car it will quit and takes two to three more tries. Also had a severe raw gas coming from the car after a fill up. The gas fumes were so severe that we had to park the car outside for fear of an explosion in our garage. I took the car to the mb dealer in pittsburgh and they were able to repair the gas problem as the gaskets around the gas tank were dry-rotted and I paid approx $600. 00 for this repair which I feel that mb should have covered since at 66000 miles this should not happoen. As usual they could not duplicate the stalling issue. Mb know of this problem but will not do anything since it doesn't show up on there computer hook-ups. Something needs to be done before people get killed. I'm sure I'm not the only one this happens too.

The contact owns a 2006 Mercedes Benz Clk350. The contact stated that there was a strong odor of fuel outside of the vehicle. There was no fuel visible on the ground. The contact replaced the fuel level sending unit. The failure recurred and the vehicle was taken to the dealer, who replaced the fuel level sending unit located on the driver's side of the fuel tank. The manufacturer was notified of the failure. The approximate failure mileage was 35,000.

Vehicle was purchased from an authorized Mercedes Benz dealership and was a certified pre-owned vehicle. Automobile was garage kept and primarily driven to work with highway miles. Only premium non-ethanol mixed fuel was used from shell. Suddenly, one day, strong gasoline odor permeates garage. Most noticeable with full tank. The cause was a fuel tank sender unit. A plastic diaphragm within the unit developed a stress crack right at the boundary between two faces. It is clear that proper bonding between the two was not ideal during molding. Fuel would egress out this crack located under the back seat and on-top of the fuel tank. $1000 was recently spent on the replacement of sender unit. Some fuel odor still persists within vehicle. This was clearly a manufacturing defect and surprising considering the low miles and years on the vehicle. Regardless of ramifications, gasoline of sufficient quantity in places unintended, shows poor workmanship. Thank you. Updated 02/14/lj the consumer stated it appeared the plastic vessel itself was made by a tier supplier in germany. The leak stared from the seam.
