Complaint (2) about gearing in low RPM’sservice

After a vacation where I drove across Europe and back home, noticed following symptoms.

Car is starting to make the grinding noise on more frequent basis. Now I can almost always provocate the noise in second and third gear. Especially when coasting and downshifting (on itself) from third to second gear. Occasionally the grinding noise would be audible in almost all gears except seventh. Also, I’ve experienced, twice,  that when holding still, engine would stall and shut off. Stalling happened once in reverse gear. Display for the gear indicator would only show “D” as no gears are selected. Usually is shows in which gear it is eg. “D2”.

But dealership is refusing to do anything about it, as they are saying that it should be like that. But I disagree, and am looking for second opinion.
