I have a regular Giulia Q4. Sometimes when I have made a stop for about an hour and leave with the engine temp gauge at about two bars, I will stop at the exit with the brake applied and wait to go. The engine will go up to about 1200 rpm (like a fast idle) but there is no push. It almost feels as if it's out of gear. When I release the brake and exit the idle speed goes down to regular. This only happens when the engine is about half warm. When I leave the garage in the morning when the engine is dead cold this doesn't happen. I have absolutely no problems with this transmission otherwise.The shift points and power transfer are excellent (unlike every Fiat automatic I've ever owned). The dealer has no flash updates for this car at this time.
