2017 Ford Expedition: check engine light

Filed Dec 24, 2025 · Driver assistance, Transmission · TX

We were driving on the highway and suddenly lost all power. Vehicle downshifted so hard I thought someone had hit us. Then it was back to normal, driving fine. But now we had no speedometer and the check engine and wrench light were on. My wife said she had felt something like that before but it was minor and at a lower speed. It had never resulted in a check engine light or loss of speedometer. I told her to exit the highway. She was shaking like crazy because she thought we just got rear ended. I can see how this could cause someone to completely wreck it was so harsh. We towed it home and when we started it up at home all those error lights were off. So I drove it around the block and it drive fine. I had my friend come take a look. He scanned it and it had a P0720 code. He said his F150 had the same issue and the same code as well a few years back and it was covered. It turns out we have the same transmission in our Expedition that he has in his F150. I havent had a chance to call the dealer yet but the paper I read in the recall and extended waranty coverage states only going up to a 2013 vehicle. They say it was a leadframe issue causing this. My Expedition has the same leadframe, and the same issue. This is very much a saftey concern since it changes harshness of downshifting out of no where. It could be even worse next time locking the wheels up or blowing the engine. Knowing its the same transmission and the same leadframe, why isnt my year model under that recall. I was reading in the forums and there are hundreds of similar questions coming from people with Expeditions and F150s that are near to my year and not covered. Can you please let me know if there is something im missing. Thank you.

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.

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.

We were out of town driving to a baseball tournament going 80 miles an hour when the car completely lost power and a wrench came up. My husband barely coasted us to a shoulder. The car would not reset or restart unless it was in park. Happens twice. Took it for code read they said it is a throttle body issue but that instead of check engine light it shuts the whole car down until reset. Very scary on the interstate. Could have easily been in a bad collision.

This issue has happened multiple times, once on the highway the vehicle felt like it lost gear/ the engine completely cut off. multiple warning lights came on such as airbag, ABS, engine light. was eventually able to get to the shoulder and after multiple attempts it started back up, showed no warning lights. drove the rest of the way fine. another time that could have put other at risk is when driving in the city, the vehicle lost power and also lost the ability to stee. causing me to be standstill in the roadway. the vehicle started back up after two attempts. the vehicle has been to the local deal a total of 4 times with the last time requesting a through inspection of the grounds, as this seems like an electrical or mechanical issue the service manager requesting me "not to bring it back until it's broken" leaves me lost.

We were on vacation and on our way back to the hotel from hiking on our last night in North Carolina. The check engine light came on and the car started sputtering and the accelerator would not work. We were slowing down and the car just would not go. We put it in park and turned the car off and sat there for 10 minutes. We turned the car back on and and then the wrench light came on. We had to keep turning the car on and off for the last 5 miles of the drive home which took us over an hour with letting the car cool off and turning it back on. When we did manage to go, we could only drive 25 mph. This was on a holiday weekend. We had to pay another $150 to stay where we were to get the car towed to the dealership. We then had to wait for the dealership to open to take the car and fix the problem which then cost me $800. Now prior to even going on vacation, I had the car completely checked over and service done. Nevermind, that the warranty had just expired on it. But who thought that with actually taking care of your car, it would break down and as soon as weeks after the warranty is up. I looked online and saw that this issue has been an ongoing issue for thousands of other Ford Expeditions. I would like my money back and this to be recalled. I've attached all the paperwork. It is due to an inoperable throttle sensor where the throttle then fails to work. Please recall this issue and have them return my money.

Driving through a mile-long tunnel on an interstate highway (speed limit 55 mph), the vehicle ceased to respond to the gas pedal and would not accelerate or maintain speed. Attempted to shift gears but that produced no change - it was as if the transmission was stuck in neutral, but pushing the gas pedal did not increase the rpm. As we exited the tunnel at approximately 30 mph, the driver attempted to pull over and stop the vehicle, and found that the power assist for the brakes was not working, making stopping difficult - the driver had to push the brakes very hard, multiple times, to stop the car. We did contact 911 dispatch when we thought we were going to likely impede traffic, as the tunnel only had two lanes traveling the same direction. However, no intervention was required as we reached the end of the tunnel and were able to pull over before the call was completed. The vehicle was towed to a dealership and they diagnosed a fuel pump and/or fuel pump module problem, but have ceased to respond to our calls for the past 48 hours, so we have no further information. The check engine light turned on when the car was restarted, but then later turned off, without any repair work having been completed.

Ford Expedition suddenly lost acceleration while driving. This results in the accelerator producing no power, essentially placing the vehicle into neutral. After turning vehicle on & off, it worked properly. Took it into auto repair place & was told this is a common problem and the THROTTLE MOTOR had to be replaced. After replacement, vehicle was towing a boat and the same thing happened and the check engine light came on. However, this time, after about 20 seconds, the vehicle shifted back into gear, the engine light turned off, and vehicle operated properly for the rest of the drive.
