Done with Mercedes Benz
After quite lengthy unsuccessful efforts to get Mercedes Benz to address the fuel dilution to the engine oil issue on my wife's GLA (do a search if you need more info - I also have numerous other items of information I did not post), we have disposed of the car and will not be purchasing another MB vehicle again. If only MB corporate had been honest and said 'yes, this is a known phenomenon that has no remedy' instead of 'there is no problem,' perhaps I could have resigned myself to it. But their numerous and continued denials, obfuscations and misrepresentations have left me with no respect for the organization, the people therein, or their product. (As for the local dealer's participation in the charade, I will not be purchasing any of his remaining brands - VW, Nissan, Audi, Porsche, Volvo - from him.) For what it is worth, we have purchased a vehicle that does not have a direct injection engine - a difficult task indeed.
For those of you who were truly concerned about this aspect of the MB experience, I wish you the best in your ownership journey. To those of you who scorned me because I was not into MB ownership for the culture, lifestyle, prestige and status aspects, I trust that you will celebrate my departure. I know I do.
