2015 FORD C-MAX Power Train Problems

A low rumbling noise seemingly situated at the right front (passenger) tire started with no warning approximately two months prior; no warning lights came on, the car did not change its driving--only a low rumbling noise which increased in revolutions with acceleration and quietened with braking and when in neutral--emerged. I subsequently took the car to a local mechanic to evaluate if the brakes were failing but in his diagnosis, he thought the likely cause to be internal to the transmission--a finding now confirmed by two other mechanics, including the Ford dealership. However, in researching this issue, a Technical Service Bulletin (20-2219) outlining this known issue with the transmission of the 2013-2016 Ford C-max built before August 2015 (mine was built in April 2015) popped up, issued June 2020. My car is now marginally outside of warranty at 112,000 miles but this known issue is one that makes the car...

The contact owns a 2015 Ford C-Max. The contact stated while driving approximately 5 MPH, shifting from 1st to 2nd gear became difficult. There was no warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The contact related the failure to NHTSA Campaign Number: 22V413000 (Power Train). The approximate failure mileage was 142,000.

TL* THE CONTACT OWNS A 2015 FORD C-MAX. THE CONTACT STATED THAT WHILE DRIVING IN NON-ECO MODE, THE VEHICLE FAILED TO MAINTAIN HIGHWAY SPEEDS AND DECELERATED INDEPENDENTLY. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER ORIGIN LOCATED AT 6400 N 51ST AVE, GLENDALE, AZ 85301, AND WAS DIAGNOSED WITH A DEFECTIVE TRANSMISSION. THE CONTACT WAS INFORMED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED BUT NO ASSISTANCE WAS OFFERED. THE FAILURE MILEAGE WAS 55,000. *BF*JB

VEHICLE IS NOT HOLDING EV NOW/LATER MODES CAUSING UNEXPECTED BATTERY USAGE AND FUEL CONSUMPTION. AN EXAMPLE IS TRAVELING HIGHWAY SPEEDS (70-75 MPH); VEHICLE WILL UNEXPECTEDLY SWITCH INTO AUTO MODE AND REVERT FROM GAS/HYBRID PERFORMANCE TO ELECTRIC/BATTERY ONLY PERFORMANCE WHICH IS REDUCED POWER AND RESPONSE AGAIN AT HIGHWAY SPEEDS. THIS IS NOT ALWAYS THE CASE AS I HAVE FOUND THIS TO HAPPEN BEFORE I ENTER THE HIGHWAY AND CAN ADJUST MY DRIVE ACCORDINGLY. ADDITIONALLY, THIS HAPPENS IN EV NOW MODE WHICH HOLDS THE ELECTRIC ENGINE TO PREVENT GAS USE AT ALL BUT THE SYSTEM WILL INADVERTENTLY SWITCH TO THE AUTO MODE. CONDITION IS EXTREMELY SPORADIC AND DIFFICULT TO REPLICATE MOST TIMES WILL HAPPEN WITHOUT THROWING A CHECK ENGINE LIGHT CODE. FORTUNATELY I DO HAVE A FEW INSTANCES WHERE A CODE WAS THROWN AND I WAS ABLE TO HAVE THE DEALER TAKE A LOOK AND MAKE SOME WARRANTY REPAIRS NONE OF WHICH...

DRIVING MY 2015 FORD C-MAX AND ALL OF A SUDDEN I LOSE POWER. I PRESS THE GAS AND NOTHING. I WAS DRIVING THROUGH A INTERSECTION AND HAD TO COAST TO THE SIDE OF THE RODE. BIG RED TRIANGLE SHOW UP SAYING "STOP SAFELY NOW". CAR HAS BEEN AT THE DEALER FOR 4 DAYS, THEY ARE TRYING TO FIND THE PROBLEM. I HAVE READ ONLINE ABOUT THIS PROBLEM WITH MULTIPLE FORD VEHICLES AND A RECALL WAS CALLED FOR THE FOCUS. I GUESS FORD IS TO BIG TO GO AFTER AND THE NTSB DRAGS THERE FEET LIKE NO OTHER. CALL FOR A RECALL ON ALL VEHICLES THAT "STOP SAFELY NOW'. WILL YOU WAIT UNTIL PEOPLE DIE TO DO SOMETHING!!

1. ON TAKING A TRIP FROM PANAMA CITY BEACH, FL TO INDIANAPOLIS, IN THIS CMAX WAS PARKED & LOCKED IN THE NORTHWEST FLORIDA BEACHES PARKING LOT AT APPROXIMATELY 9 AM CST 2. AT APPROXIMATELY 4:30 PM EST A TELEPHONE CALL WAS RECEIVED FROM THE AIRPORT POLICE INFORMING ME THAT THE CMAX WAS IN THE PARKING LOT RUNNING WITH THE LIGHTS ON AND I WAS ASKED TO GO TO THE PARKING LOT AND TURN THE AUTOMOBILE OFF. AFTER I INFORMED THE OFFICER THAT I WAS IN INDIANA AND COULD NOT COMPLY WITH THE REQUEST, I PROCEEDED TO MAKE NUMEROUS TELEPHONE CALLS; FORD MOTOR COMPANY, GARY SMITH FORD AND OTHERS IN AN ATTEMPT TO HAVE THE CMAX TURNED OFF BUT WAS TOLD IT COULD NOT BE DONE. I THEN RETURNED OFFICER'S CALL AND ASKED THAT THEY GO TO THE PARKING LOT, BREAK THE DRIVERS WINDOW, AND PRESS THE START/STOP BUTTON TO TURN...

REVERSE GEAR SETTING ACTUALLY PUT THE CAR IN DRIVE AFTER STARTING THE PARKED CAR ND ATTEMPTING TO BACK OUT OFPARKING SPACE. I TRIED TURNING OFF ENGINE, AND THE SAME THING OCCURRED, THE CAR CONTINUED TO CREEP FORWARD UNTIL THE CAR MADE CONTACT WITH THE PARKING SPACE SIGN. THIS IS NOT A SMALL ISSUE AS 1) IT PROBABLY OCCURRED PREVIOUSLY WITH THE SAME MODEL IN THE SAME FLEET AND LEASER CHARGED ME UPWARD OF FIVE HUNDRED DOLLARS TO FIX VOSMETIC DAMAGE CAUSED WHILE PARALLEL PARKING AND 2) THUS COULD CAUSE BODILY INJURY HAD THE PARKING SPACE NOT BEEN BLOCKED IN FRONT. THESE CARS ARE PART OF A MEMBERSHIP BASED RENTAL FLEET, AND SHOULD BE HIGHLY MAINTAINED. AFTER CONTACTING THE EMERGENCY NUMBER OF THE FLEET LEASER, I WAS A FEW MINUTES LATER ABLE TO REENTER AND START THE CAR, AND THE REVERSE GEAR OPERATED PROPERLY. THE LEASER HAS PREVIOUSLY RAISED MY INSURANCE...
