2012 Mercedes-Benz E-Class E350 2dr Coupe (3.5L 6cyl 7A)
Until April of 2013, I thought this was one of the best MB models I have ever owned. That was until the dealer informed me about a new service bulletin when I brought the car in for the 10,000 mile service. Short story is that a bad lot of wrist pins installed in the engine will need replacement. So, three weeks later I had the car back with a rebuilt engine! They replaced the pistons, connecting rods and wrist pins along with every other engine gasket, seal and screw!
