2017 Ford Expedition Power Train

TSB 23-2143, citing cold-start cam phaser rattle as a manufacturing defect that impacts reliability and safety (loss of power, premature wear, noise).

The transmission suddenly downshifted to 1st gear while traveling at 45 mph with no warning. This created a very dangerous and life threatening occurence.

The vehicle has not been inspected by anybody so the problem is not been reproduced. It just happened this morning. There have not been any check engine lights or anything related pop up on the dash. I was leaving my house I just reached highway speeds 50 to 60 miles per hour I was in 5th or 6th Gear. The transmission suddenly downshifted on its own to first gear it downshifted so hard and so fast that it barked the tires really hard the RPMs went up to 5 to 6,000 I thought that it had somehow been hit into reverse or park or something I am the only one in the vehicle. I shift the vehicle into neutral and then I went back down to manual and cycled up and down a gear and then put it back in Drive.

Truck first would shift out of park but would not engage into a gear causing it to roll unexpectedly in the downhill driveway. Problem self corrected with a few ignition cycles. Week later truck became inoperable at a stop light and require shut down and restart and traffic. Same day truck would not start at all after returning home. Dealer diagnosed 6r80 transmission with molded lead frame assembly failure. This has been subject of a recall or customer satisfaction program for earlier year models but not beyond 2013.

While driving, the speedometer began to bounce around. This caused erratic shifting. At one point the speedometer went to zero while we were still moving. I pulled over put it in park and it would not go into gear. During this the air bag light came on. After turning the vehicle off and back on again, everything went back to normal. Over a period of days, it would do the same thing again, but not as bad as the time listed above. The speedometer will bounce around while driving and cause moderate shifting issues. I took the vehicle into a shop, and they ran the code as being Output Speed Sensor. After research, it appears Ford had a recall on output speed sensors for 2014 F-150 vehicles (Recall Reference Number 24S37) which use the 6R80 transmission. I contacted my local Ford dealership and Ford corporate via chat, and both told me my 2017 Expedition was not covered under that recall. Since my vehicle uses the same transmission, I inquired as to what they did to fix the output speed sensor issue. They could not provide me with that information. I have several videos of the speedometer bouncing around, but am unable to upload them here.

I am about to have the rear end rebuilt for the 2nd time since I bout the vehicle roughly 1 year ago, and am currently over 30th in line at my dealership to have a rear end rebuilt

At roughly 95,000 miles the bearings in the rear differential went bad on our Expedition EL. We drove it this way for a few months until we could get it properly diagnosed and repaired. It was repaired by Stearns Ford under our extended warranty (aftermarket) several weeks ago, and has been fine since the rebuild.

While driving, the vehicle suddenly went into a "limp mode" where it lost almost all power and a Power Train warning light came on. This happened once on July 14th and then again 5 times on August 2nd, 2002. The car was not drivable after the consecutive incidents so it had to be towed to the dealership. It was determined the Throttle Body had failed and needed to be replaced and because the car was about 2,500 miles beyond the power train warranty terms the repairs cost $790.

While driving today my vehicle lost power and went into limp mode. the warning wrench came on. This is very dangerous, especially on the freeway. There is no where to get off and the vehicle slows to a stop in the middle of traffic. I turned the vehicle off and restarted it to reset the warning. I did get home, very bad situation in the middle of traffic without any warning.

I WAS DRIVING DOWN THE ROAD AND ALL OF A SUDDEN WHEN I PRESSED THE GAS IT WAS NOT WORKING AND SO I USED THE BRAKE TO PULL OVER. THE WRENCH LIGHT CAME ON. WHEN PARKED CAR STARTED SHAKING/GRAMBLING SOUND. EVERYTHING ELSE WORKING BUT THE GAS PEDAL DID NOT GO WHEN PRESSED. TURNED CAR BACK ON AND WRENCH LIGHT APPEAR AND CAR DRIVES.

WHILE DRIVING THE TRANSMISSION COOLER LINE FAILED AND BROKE IN HALF CAUSING ALL THE FLUID TO PUMP OUT OF TRANSMISSION IMMEDIATELY AND CAUSED THE VEHICLE TO STOP MOVING ON A VERY BUSY FAST MOVING ROAD. VEHICLE HAS ONLY 34000 MILES ON IT AND HAS BEEN SERVICED ONLY BY FORD. FORD TELLS US THE TRANSMISSION NOW NEEDS TO BE REPLACED AT OUR COST AND IS NOT COVED UNDER THEIR POWERTRAIN WARRANTY. AFTER INSPECTING THE TRANSMISSION LINE THE ENTIRE DEALERSHIP AGREES THAT IT WAS A DEFECTIVE PART.

WHEN DRIVING MY FORD EXPEDITION WOULD AUTOMATICALLY DOWNSHIFT WITH NO WARNING AT HIGH SPEEDS. WHEN DOING 55MPH IT DOWNSHIFTED, AND THREW ME THE DRIVER ALMOST INTO THE STIRRING WHEEL. AT ANOTHER TIME IT THREW MY 11 YEAR OLD SON INTO THE DASH. IT FELT LIKE YOU WAS GETTING REAR ENDED WITH A BAD CASE OF WHIPLASH.

DURING ACCELERATION TOWARDS 60MPH- 70MPH THE TRUCK WILL BEGIN TO VIBRATE A LITTLE, THEN THE WRENCH LIGHT COMES ON. AS YOU SETTLE ON A SPEED THE VIBRATION STOPS UNLESS YOU HAVE TO SLOW DOWN TO SPEED BACK UP. ONCE YOU PULL OVER AND TURN THE TRUCK OFF FOR A BIT AND TURN IT ON THE WRENCH DISAPPEARS.

VEHICLE WAS PULLED 3/4 INTO THE GARAGE WITH THE BACK WHEELS ON THE APPROACH OF THE DRIVEWAY. VEHICLE WAS PUT INTO PARK AND SHUT OFF. I RETURNED TO THE GARAGE 10 MINUTES LATER TO FIND THE VEHICLE HAD ROLLED DOWN THE DRIVEWAY, STRIKING A TREE CAUSING SIGNIFICANT DAMAGE. VEHICLE WAS FOUND TO BE IN PARK AND STARTED UP WITHOUT ANY PROBLEMS. IN THE LAST COUPLE OF DAYS I HAVE NOTICED INCONSISTENCY WITH THE VEHICLE'S SHIFTER WHEN PLACING IT IN PARK. I HAVE SEEN IT GET HUNG UP BETWEEN REVERSE AND PARK. THIS IS A BRAND NEW FLEET VEHICLE WITH 1049 CURRENT MILES. IT JUST WENT INTO SERVICE ON JULY 5TH.
