| Description of the problem | 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 02/14/13*lj the consumer stated it appeared the plastic vessel itself was made by a tier supplier in germany. The leak stared from the seam. |
