Along with routine oil and filter, I reported that the auto engine stop/start (at stops) was not functioning. The engine ALWAYS remains on (it used to turn off at red lights). The mechanic looked but couldn't find anything wrong, although he said that for this function to work, everything has to be just right. I decided to let it go... the car just stays running at red lights.

MB is going semi-autonomous - repairs don't necessarily fit into standard categories - and in fact crosses over several systems. Seriously need to consider a new category - this is the future and it's problematic. 360 degree camera control was replaced (but improperly aligned). It interact with Lane Keeping Assist, Steering Assist, Braking and I have no idea what else . Driver assist systems quit when this fails Another increasingly common system that's difficult to classify. The Eco Start/Stop system quit working as designed. It has essentially working backwards, functioning when unexpected, not functioning when anticipated. Dealer couldn't find issue, so said it was fine. Hasn't worked once in two months - even though all known parameters have been met - engine at operating temp, passenger compartment st set temps, fully charged (hopefully after 100+ miles) but no longer working. Dealer seems beyond their depth with these systems so to save frustration I've decided to just pretend I don't have the features

Another attempt to repair the Steering Assist function of the Distronic Cruise Control, and Start Stop. Dealer assured me not that all was well, but that it was good as it was going to get. Left dealer, engaged the Steering Assist, and cruised right off the side of the road. Appearently self driving is farther off than we might think. With lowered expectations I bought a second Mercedes, but didn't go for the Distronic System, a must have option if it worked. That problem solved, the new car convinces me that the start/stop on the 2016 simply doesn't work, hasn't worked in months, while the new car hasn't missed a day yet. M-B gets it in their mind that something works fine there's nothing a customer can say or do to change their mind.
