See below for details. Safety: Thankfully i was not driving 70+MPH down a busy highway when the car shut down.

FUEL PUMP CONTROL MODULE HAS FAILED TWICE. FIRST TIME VEHICLE WAS STRANDED IN MIDDLE OF 6 LANE HIGHWAY. SECOND TIME WAS NOT AS SERIOUS LOCATION. THIS PART FAILS WITHOUT ANY NOTICE AND VEHICLE CAN NOT BE PUT IN NETURAL TO BE PUSHED OR TOWED WITHOUT A LOT OF DIFFICULTY. SERVICE MANAGER TOLD ME THEY CHANGE UP TO 15 OF THESE MODULES A MONTH. SAME PART FOR CADILLAC MODLES XT5,XT6 AND ESCALADE. AND STATED HE IS AWARE SOME VEHICLES HAVE BEEN DISABLED IN VERY SERIOUS CONDITIONS
My new car has a serious lag issue. The car is not responsive to the gas pedal. You have to press the gas a lot to get moving. Once moving a lot lag. If I press it fast. Completely non responsive. My car is slower than any other car I have driven. Although this is 310 HP. Feeels like 150 HP. And I get only 12-15 miles to the gallon. Regular driving in suburbs and highway.
