2016 FORD TRANSIT CONNECT Fuelpropulsion System Problems

JUST GOT THIS VEHICLE, WAS PURCHASED AS USED BUT WITH WARRANTY STILL AS IT ONLY HAD 16500 MILES. AFTER DRIVING FOR FEW WEEKS I HAD THE FOLLOWING PROBLEMS. #1 FUEL ECONOMY ON VEHICLE IS 15 MILES PER GALLON (ON A 4 CYLINDER ENGINE?). PREVIOUSLY TAKEN TO DEALER WHERE THEY REPLACED A RECALL PART (THROTTLE BODY) AS IT WAS DOING ONLY 13 MILES TO THE GALLON. DEALER STATES THAT IS WORKING NORMAL???? #2 AFTER DRIVING FOR 4 HOURS OR MORE (CITY OR HIGHWAY) HOT AIR COMES OUT OF AIR VENTS EVEN WHEN OUTSIDE TEMP IS 40 DEGREES FE.( AND TEMP IS SET TO LOW ON CLUSTER). 20 DEGREES DEFERENCE IS NOT OK (MAYBE IN WINTER BUT NOT IN SUMMER). DEALER WAS ABLE TO REPLICATE THE PROBLEM AND CALL FORD ENGINEERS, TO WHICH THEY SAID THAT IT IS NORMAL. DEALER WAS ABLE TO REPLICATE THE SAME ISSUE ON 3 SIMILAR VEHICLES BUT...

THE VEHICLE CUT OFF WHILE IN TRANSIT POWER STEERING GOES OUT FIRST BATTERY LIGHT COMES ON VEHICLE STOPS CAN NOT RESTART

FUEL EFFICIENCY FAR FROM STATED. THIS IA AN XLT MODEL WITH A 1.6L ECOBOOST ENGINE, AND A STATED MPG EFFICIENCY OF 25/29. THE ACTUAL MEASURED HWY EFFICIENCY IS 22.3 MPG WHILE ON CRUISE CONTROL, AT INTERSTATE HIGHWAY POSTED SPEED LIMITS, ON WIND-LESS, SUNNY DAYS, AND ZERO-LOAD OTHER THAN DRIVER'S WEIGHT. THE EFFICIENCY ABOVE NOTED HAS BEEN REPETITIVELY MEASURED OVER THE FIRST 3,500 MILES OF VEHICLE USE.
