2017 Ford Expedition acceleration problems

VEHICLE SPEED CONTROL

Vehicle suddenly shifts to 1st gear while travelling at 45MPH or more causing immediate jerking and slowing of vehicle, placing driver, occupants and other drivers at risk of crash. In this condition, the speedometer reads 0MPH while still travelling and other warnings on dash are: Airbag Failure, Blindspot system fault, Cross traffic system fault, and See manual. Vehicle then appears stuck in 3rd gear until pulling over, stopping the engine and restarting. All warnings clear after restarting. This has occurred many times without proper diagnosis from Ford service. Now vehicle is doing this two to three times weekly and is currently in Ford service. Now diagnosed as Lead Frame Failure. Estimated cost is $1,523.38 and Ford refuses to pay for repair due to no active recalls on this specific vehicle, however the same transmission issue is in recall on same year model F-150's with the same transmission.

VEHICLE SPEED CONTROL

Sudden and severe downshifts occurred at roadway and highway speeds resulting in sudden speed decrease. Also revving and loss of power occurred. Problem codes P0706 & P0707 were logged which point directly to the Transmission Range Sensor (TRS), which is integrated into the molded lead frame. This sudden and uncontrolled loss of speed caused significant danger to vehicles, ocupants, and other vehicles.

For 1.5+ years, the transmission will unexpectedly and suddenly downshift into 1st gear without warning. Which causes a sudden deceleration. No warning lights before it happens. It occurs randomly and at different speeds. It has happened over 20 times. I've experienced it happening at speed ranging from 35mph to 65mph. The gear shifter was in the drive position each time this issue occurred. The suv is the 2017 ford expedition EL with the 3.5L ecoboost engine with 6 speed automatic transmission. No check engine light before or after the issue (so no OBD2 code to read) a big yellow warning appears during/after saying "see manual". Sometimes the issue will resolve in a few seconds. The suv has not been to the dealership yet for this issue. But i will be contacting ford today.

Driving vehicle on road and car lost all acceleration power. The check engine light appeared and the problem was diagnosed as a faulty throttle body. This exact same issue has been identified as a recall item with an extended warranty (ten years or 150,000 miles) on other Ford vehicles but for some unknown reason the 2017 expedition is not covered. THIS IS A VERY SERIOUS SAFETY ISSUE... I did speak to Ford and they offered no assistance.

I can be driving up a hill the traction control warning light and hill decent braking light come on causing the vehicle speed to drop the vehicle shakes acting like it is trying to stop.

In 2022, around mileage of 67000, our SUV was climbing a steep road when it suddenly made a pop sound & went into limp mode with the wrench light showing and the engine sounding rough. It felt like no fuel was getting to the engine & the gas pedal was non-responsive. The RPMs didn't change when the gas pedal was pressed. The grade was so steep, we barely made it to the side of the road without rolling backwards into traffic behind us. After turning the engine off and sitting about 10 mins, we tried starting the engine again. The car seemed to have reset itself! It ran fine; the wrench light turned off, and the gas pedal was responsive again. (At the time, we were on vacation at the coast and had traveled from our home at about elevation 3500'. We had also recently had to buy gas from a small no name gas station, so we feared we may have gotten bad fuel). From there, we returned home without re-occurrence, and we used fuel cleaning additive to our Chevron fuel for the next 2 fill ups. Then, approximately 600 miles later on a flat grade, it happened again without the pop sound. We immediately went to our Ford dealer who found no error code but found our purge valve stuck open. They recommended we replace it, which we did, and we operated the vehicle for 2 years without re-occurrence and using only Chevron gas. Recently, it happened again! Luckily, we weren't on a steep grade this time or on the freeway, but if a car would have been behind us, we would have likely been rear ended, especially had we been on the freeway. Once again, we shut the engine off, and it reset with the wrench light disappearing, so no diagnostic code got thrown AGAIN! Based on many complaints, this appears to be a common problem. It's very dangerous as the car immediately losses power to a crawl no matter what speed you are traveling at the time. It seems to be the electronic throttle body in instances where the SUV can stay running, so a code can be obtained before it resets.

Driving at highway speed, vehicle gauges drops to zero and transmission stays at 3rd gear. Unable to know what travel speed is while trying to exit safety off highway. Have to turn off engine to reset issue, but no way to figure out what happened.

Than again on July 23, 2022, was on interstate and wrench illuminated and again stalled. 75 Mph traffic and thank goodness we was able to clear traffic to side of road. Limped home. 1st incident mileage was 118395. And second incident 128024.3

VEHICLE SPEED CONTROL:THROTTLE

The electronic throttle body gets stuck closed. The engine stalls or goes into limp mode. At highway speed I then have to try and navigate a dead car to the shoulder or am stuck in the middle lane with cars going past at 70+ mph. This is a known defect in fords engine and other years/models are recalled. 2017 Ford Expedition needs to be added immediately. This is dangerous.

VEHICLE SPEED CONTROL:THROTTLE

I WAS DRIVING TO A SCHEDULED APPOINTMENT WITH OUR LOCAL FORD DEALERSHIP FOR ANOTHER ISSUE WHICH NEEDED CORRECTING WHEN ALL OF A SUDDEN THE VEHICLE WOULD NOT ACCELERATE. THE CARS ENGINE WAS STILL RUNNING BUT NO ACCELERATION. I MANAGED TO GET OFF THE ROAD, WITHOUT BEING HIT, AND CONTINUED TO THE DEALERSHIP. I LET THEM KNOW WHAT HAD HAPPENED BUT THEY BLAMED THE INCIDENT ON A BAD BATTERY AND I THOUGHT THE ISSUE WAS FIXED. THIS IS WHERE THE ISSUE BECOMES CATASTROPHIC IN MY OPINION. ON NOVEMBER 1, 2020 MY WIFE AND TWO FRIENDS WERE IN THE VEHICLE AND HEADING OUT OF TOWN. WE LIVE IN A MOUNTAINOUS PART OF ARIZONA. FORTUNATELY WE WERE ON A FAIRLY LEVEL STRETCH AND IN THE RIGHT LANE. THE VEHICLE'S ACCELERATOR AGAIN FAILED TO FUNCTION. WE PULLED OFF THE ROAD TO THE SHOULDER. TURNED OFF THE ENGINE, RESTARTED THE CAR AND TURNED AROUND AND WENT BACK HOME, ABOUT A 120 MILE DETOUR. WE CALLED THE DEALERSHIP TO HAVE THEM DO A DIAGNOSTIC. THEY DETERMINED IT TO BE A FAILED THROTTLE BODY SENSOR. THIS INCIDENT COULD HAVE TURNED OUT MUCH WORSE. HAD WE BEEN PASSING A TRUCK, CAUGHT IN THE LEFT LANE AND ON A STEEP GRADE WITH NO ACCELERATION, WHO KNOWS THE OUTCOME. I CONTACTED FORD FOR THEM TO REIMBURSE ME FOR THE COST OF THE THROTTLE BODY REPAIR/REPLACEMENT. THEY DID COVER THAT COST, BUT I ALSO ASKED THEM TO GIVE ME AN ASSURANCE THE REPLACEMENT PART WOULD NOT DO THE SAME FAILURE AFTER SO MANY MILES. BY THE WAY OUR VEHICLE ONLY HAD 55K MILES WHEN THIS HAPPENED. I HAVE SINCE LEARNED FROM THE DEALERSHIP THAT THIS FAILURE (BAD SENSOR) OCCURS WITH FREQUENCY IN SIMILAR VEHICLES. IF THE FAILURE OCCURRED IN THE SCENARIO I MENTIONED ABOVE, WHO WOULD KNOW IT WAS THE THROTTLE BODY SENSOR THAT FAILED, RATHER THAN A DRIVER ERROR. IT IS A FAILURE THAT COULD BE CATASTROPHIC, AND PROBABLY HAS BEEN WITHOUT CONSEQUENCES. I ASKED FORD WHY THIS WASN'T A RECALL ACTION, NO RESPONSE. WHERE IS THE NHTSA?

VEHICLE SUDDENLY LOOSES ENGINE POWER WHILE DRIVING AND GOES INTO SAFE (OR LIMP) MODE. STEPPING ON THE ACCELERATOR DOES NOTHING, IT DOESN'T EVEN REV THE ENGINE, IT'S SIMILAR TO BEING IN NEUTRAL. IT HAS OCCURRED ON 3 SEPARATE OCCASIONS, MONTHS BETWEEN EVENTS - FIRST, WHILE ATTEMPTING TO ACCELERATE ONTO AN INTERSTATE HIGHWAY, WE SUDDENLY LOSE ENGINE POWER WHILE ATTEMPTING TO MERGE INTO THE RIGHT LANE OF TRAFFIC. WE FORCED TO SLIDE OVER ONTO THE RIGHT SHOULDER AND STOP. SECOND OCCURRENCE HAPPENED WHILE DRIVING DOWN A CITY STREET. WE SUDDENLY LOSE ENGINE POWER AND ARE FORCED TO TURN ONTO A NEIGHBORHOOD STREET AND COME TO A COMPLETE STOP. THIRD TIME, AGAIN DRIVING DOWN A CITY STREET, SUDDENLY LOSE ENGINE POWER BUT THERE WAS NO WHERE TO PULLOVER OR SIDE STREET TO TURN ONTO. WE FORCED TO STOP THE VEHICLE IN THE MIDDLE ROAD. LUCKILY NO ONE WAS DIRECTLY BEHIND US. IN ALL CASES, TURNING THE ENGINE OFF, WAITING A MINUTE, AND THEN RESTARTING THE VEHICLE "FIXED" OR CLEARED THE ISSUE AND WE WERE ABLE TO CONTINUE DRIVING. NO OBD-II CODES THROWN AFTER THE EVENT. FORD DEALER REPLACED THE ELECTRONIC THROTTLE BODY AND SO FAR WE HAVEN'T SEEN THE ISSUE.

LAST WEEK, MY 2017 FORD EXPEDITION EXPERIENCED A SITUATION WHERE WHILE DRIVING THE VEHICLE SUDDENLY STOPPED RUNNING. I WAS FORCED TO COAST OVER TO THE SIDE OF THE ROAD WHEN THIS HAPPENED, AS THE ENGINE WAS RUNNING BUT MY ACCELERATOR PEDAL WAS NOT OPERATING AND THE VEHICLE WOULD NOT MOVE. FORTUNATELY, AFTER SHUTTING THE VEHICLE OFF, I WAS ABLE TO RESTART IT AND CONTINUE DRIVING. IN THE SPACE OF 24 HOURS THIS HAPPENED SIX (6) TIMES. AFTER THE SIXTH OCCURRENCE, I DROVE TO THE FORD DEALERSHIP AND THEY DIAGNOSED THE ISSUE AS A THROTTLE BODY AND MOTOR.
