2015 Chevrolet Spark Fuel System Problems

THIS VEHICLE HAS BEEN VERY SLUGGISH SINCE I BOUGHT IT. IT IS NOW UNSAFE TO DRIVE, ESPECIALLY IN THE HEAT. THERE HAVE BEEN MANY INSTANCES WHEN I'M AT A COMPLETE STOP AND THE CAR WON'T GO WHEN I HAVE THE GAS PEDAL FLOORED. I HAVE HAD 3 CLOSE CALLS AT INTERSECTIONS WHEN MAKING A LEFT HAND TURN, WHEN THERE SHOULD HAVE BEEN AMPLE TIME TO GET THROUGH THE INTERSECTION BASED ON THE DISTANCE BETWEEN MY VEHICLE AND ONCOMING TRAFFIC. I HAVE TAKEN MY VEHICLE TO THE CHEVROLET SERVICE DEPARTMENT FOR THIS ISSUE. THEY HAVE DONE DIAGNOSTICS AND SUPPOSEDLY DRIVEN IT, BUT COULD NOT FIND A PROBLEM. THIS IS A REAL SAFETY CONCERN. THIS HAS HAPPENED ON BUSY CITY STREETS, AT ON-RAMPS GETTING ONTO THE FREEWAY, AT BUSY INTERSECTIONS GOING STRAIGHT AND TURNING BOTH DIRECTIONS, AND ON LOW GRADE HILLS, I HAVE TO FLOOR THE GAS PEDAL TWO OR THREE TIMES BEFORE THE CAR WILL MOVE. THE PROPULSION INCREASES AT A VERY SLOW, UNSAFE RATE OF SPEED.

YOU GET FUMES INSIDE. TRAVELING AT ALL SPEEDS.

ON MAY 15, 2015, AFTER DRIVING ABOUT 15 FREEWAY MILES, I TOOK THE FREEWAY OFF RAMP. AFTER TRAVELING ABOUT 1/2 MILE, AFTER EXITING, THE "PROPULSION POWER IS REDUCED" WARNING LIGHT CAME ON FOLLOWED BY THE VEHICLE SLOWING DOWN ALTHOUGH I'M PRESSING THE ACCELERATOR FOR MORE POWER. AFTER STOPPING AT A TRAFFIC LIGHT, THE CAR MOVED VERY SLOWLY EVEN WHEN I'M FLOORING THE ACCELERATOR. I FINALLY MADE IT TO THE CHURCH PARKING LIGHT WITH THE VEHICLE TRAVELING AT ABOUT 5 MPH. THE CAR WAS TOWED BACK TO MY HOUSE, ABOUT 17 MILES AWAY. THE FAILURE COULD HAVE BEEN VERY DANGEROUS IF I WAS USING THE FREEWAY. THE "PROPULSION POWER IS REDUCED" WARNING LIGHT DID NOT COME ON THE FOLLOWING DAY WHEN THE POWER WAS TURNED ON. HOWEVER, THE "SERVICE THE VEHICLE SOON WARNING LIGHT " CAME ON THE FOLLOWING DAY. THE VEHICLE WAS TOWED TO A CHEVROLET DEALERSHIP FOR SERVICE ON 5/26/15.
