2010 FORD FLEX Power Train Problems

While driving car suddenly losses power and the wrench light comes on. Loss of power with the car transmission wont move the car at all. have to pull over and turn off car about 5min then start it back up and now everything works with no codes. Happened 3 times.VERY DANGEROUS BECUASE CAR LOSSES POWER AND CARS BEHIND YOU ALMOST HITS YOU.

POWER TAKE OFF UNIT OR POWER TRANSFER UNIT STARTED MAKING A LOUD WHINING SOUND STARTING AT 40 MPH. NOW BEING TOLD THE UNIT MUST BE REPLACED. LOOKING ONLINE AND SEEMS TO BE AN ISSUE WITH THE MAJORITY OF FOR FLEX AND FORD EDGE.

TRANSMISSION AND POWER TRANSFER UNIT (PTU). THE TRANSMISSION HAS BEEN SHIFTING AWKWARDLY SINCE 10,000 MILES. HAVE BEEN TO THE DEALER NUMEROUS TIMES AND THEY ARE UNABLE TO DIAGNOSE. A MECHANIC AT LARRY H. MILLER FORD, IN LAKEWOOD CO, RECENTLY TOLD ME THE TRANSMISSION MIGHT OR SHOULD BE RECALLED IN THE FUTURE. AT 87,506 MILES THE PTU WENT OUT AND HAD TO BE REPLACED AT A COST OF $1,692.26. THE PTU CAME ORIGINALLY WITHOUT A DRAIN PLUG AND WAS IMPOSSIBLE TO SERVICE. REPLACEMENT PTU DOES HAVE A DRAIN PUG. I BELIEVE BOTH THE TRANSMISSION AND PTU ARE DEFECTIVE DESIGNS AND NEED TO BE RECALLED.

TOTAL MOTOR FAILURE WHEN DRIVING! TRANSMISSION FREQUENTLY SLIPS. MOTOR HAD TO BE REPLACED. WHEN PRESSURE EXHAUST FOR ECOBOOST IS REDIRECTED TO CYLINDER 3 AND 5 THE HEAD GASKET FAILS ALLOWING WATER TO ENTER THE HEAD OF MOTOR WHICH THEM STEAM FRIES THE CYLINDERS. THIS IS VERY COMMON IN THE 2010 FLEX WITH ECBOOST AND NEED TO BE RECALLED ASAP! MOTORS UP TO 100,000. MINE HAD 74000 WHEN FAILURE OCCURRED. *TR

AFTER OWNING THE NEW VEHICLE FOR THREE MONTHS IT STARTED RANDOMLY SLIPPING INTO NEUTRAL. AT FIRST, IT DID THIS WHEN ACCELERATING FROM A STOP (WHICH IS VERY DANGEROUS IN BUSY INTERSECTIONS, LEFT TURNS AND MERGING). IT NOW DOES IT THEN AND IN ADDITION AT HIGHWAY SPEEDS - 50+. IT ALSO AT TIMES HAS ENGINE SURGES WHEN AT A COMPLETE STOP. IT ALSO SURGES AND HESITATES AT 45MPH TO HIGHWAY SPEEDS, AT TIMES CAUSING SUCH A SPEED VARIANCE THAT IT WILL SHUT CRUISE CONTROL OFF, SLIP INTO NEUTRAL AND RAPIDLY DECELERATE BEFORE CORRECTING ITSELF. THERE HAVE BEEN 5 REPAIR ATTEMPTS AT A FORD DEALERSHIP. THEY HAVE NOT BEEN ABLE TO DETERMINE THE PROBLEM. THEY SENT IT HOME WITH ME UNTIL IT DOES IT "ALL THE TIME" OR BREAKS DOWN. *TR
