Car Stall problems of the 2016 Chevrolet Malibu Hybrid

Vehicle in motion in left hand lane, on 5 lane main road during rush hour, traffic going approx. 35 mph. As I was driving the vehicle stalled, engine light came on and a warning message said the vehicle was "slowing down" (it stalled completely). I was unable to drift into the right lane and forced to abandon my car into the center lane - used for merging from other lanes of traffic. Police responded but no report was filed. Officer suggested I leave the vehicle for my own safety & when tow truck arrived to request the auto be towed to a safe spot for removal of personal items. This situation was not only dangerous to myself but others. A crash could have been the result. According to dealer, no recall on this issue. Did have a transmission problem. Less than 10,000 miles on car approx 18 mos old. Dealer hopes gm fix will work, but I am now nervous about driving the vehicle.
