Beginning sometime in may 2013, the car began leaking fumes into the passenger cabin which made me very ill. After taking it to both park place mercedes here in dallas, and then Mercedes Benz of plano, neither service department could determine what was wrong with the vehicle. After repeated attempts to get to the bottom of the matter with park place, I took it to Mercedes Benz of plano in November 2013. They evaluated the car, changed the battery, and gave the car back to me in December of 2013 for a weekend, claiming it was fixed. The car, however, was continuing to leak fumes into the passenger cabin, sickening me again. I returned the car to them for further evaluation. They claimed to have repaired it, but instead of getting in the car, I sent an industrial hygienist to test the inside air of the car, after starting it up and letting it run for about 15 minutes. That test found unusually large concentrations of ethanol, propene, isopropanol, acetone, toluene, hexane, and cyclohexane -- chemicals which all appear to be components of gasoline. I am still, as of this writing, in October 2014, wrangling with Mercedes Benz and Mercedes Benz of plano over repair to my car. I would be happy to provide you with a copy of the report of the air test from the interior of my 2011 Mercedes Benz E550 coupe.
