After repairs were completed on my 2012 E350 Bluetec requiring replacement of both intake manifolds my engine light came on within two days. Seems like the same problem. There is limited power. I sent a text and called 5 times over several days with no response. Repairs cost more than $5,000 and previous repairs within a few months were over $10,000. It is as if my service advisor just does not care if the work was done properly. Over the years I have purchased four Mercedes and I was planning on replacing my wife’s ML 350. Rest assured, this is not going to happen with this dealership. My car is a lemon (probably spent as much as $20,000-$30,000 that has required(?) very expensive repairs over its life time, and Clear Lake Mercedes is not the place to purchase or service your car. I’m off to Mercedes of Sugarland, Texas to use a trusted service advisor and repair shop.
