2015 Ford Expedition: sudden loss of power

Filed May 3, 2021 · Engine · 129,000 miles · AL

While passing slower traffic on I 80 experienced sudden loss of power and no throttle response. Was travelling at speed limit (80) with cruise control engaged. Luckily I was able to drive into the median to avoid a sudden slow down in the left lane line of traffic. Later diagnosed to be throttle body failure. If this would have happened in an area or situation where I could not have immediately left the road it could have resulted in a rear end collision at highway speed.

When pulling out into heavy traffic on a divided four lane road, the vehicle suddenly lost power and went into limp mode almost causing a serious accident. The check engine light came on and the code was later to be determined p2112 throttle actuator a control system stuck closed. After researching the issue it was apparent that the ford 3.5 ecoboost motor has quite a history of these type failures. Often driver safety is compromised as the vehicle suddenly and without warning will lose power just when you need it. The fix is to install a new throttle body with electronic actuator.

I was driving at approximately 50 MPH, in a steady-state in mild traffic, when the wrench icon in the left-side of the dashboard lit up momentarily and the vehicle lost all power. The engine was still running but was unresponsive. I had to coast to a stop, turn it off then re-start the vehicle. It did so again upon driving it on monday aug 19. Ford was contacted and denied the issue, even though this exactly mimics the reason for the recall on 2015 ford flexes/lincoln mkts, etc. With the same powertrain!

On today's date, april 9, 2019 at approximately 4:20pm cdt, I was entering freeway accelerating to 40 MPH when power was lost and quickly decelerated to under 5mph. Engine still running, but it went into 'limp home' mode, no faster than 5mph. Was able to get to distress lane. Wrench symbol displayed on instrument cluster. Turned off engine and checked owners manual...symbol indicated power train trouble. Turned on started ok, and continued to freeway speed. About 1 mile later, lost power again, slowing to 'limp' mode. This time check engine and wrench lights came on and engine noticeably rough running. Turned off/on started ok, exited freeway and drove city streets home, about 3 miles. Check engine light never went off. Wrench light did go off after 2nd re-start. Manual recommends having ford dealer check it out. That's what I'll be doing tomorrow. This spontaneous loss of power has risk of causing a crash from other driver's as sudden decelerations without brake light warning is very dangerous.

55,000 miles. Orange wrench warning light came on driving through town about 25 MPH. Lost power and coasted across the rail road tracks in town. Vehicle was still running, however had no power and minimal idle speed. I got pulled off to the side of the road. Diagnostic said to check manual. I tried to do that and the vehicle wasn't idling the best, so I shut it off. I was at a busy intersection and was on my way to pick up my daughter from her first day at daycare, so in a little disarray. I turned the vehicle back on and regained full functionality. The next day it replicated the error twice in about a 4 mile stretch. I got it shut off and restarted then directly over to the dealership. They have had it for 8 days and can't replicate the error.

While traveling in the passing (3rd) left lane on interstate highway with speeds of 65 to 70 MPH, the vehical totally loss power, motor still running but just at an uneven poor idle, still in gear, I attempted to accelerate, it did absolutely nothing yet the motor was still at the poor idle. On the dash comupter a wrench appeared with "see manual" along with a small check engine light above that. I was forced to get out of that dangerous situation with no power, coasting through 3 lanes with my wife waving out the passenger window to let my powerless car drift over. Once off the highway, the motor was still poorly idling, giving it gas did nothing, still just a rough idle. I shut the car off and restarted it and miraculously I once again had control of the accelerator. I was still 3 hours from home with all highway driving ahead of me, which I did doing 55mph in the slow lane & ready to turn off road. I bought a new vehicle as to not have problems, let alone the most dangerous episode of our lives. What really is unacceptable is that I just had a 70k mile checkup at a local ford dealer where I was told they reccomend changing my transfer case oil along with an oil change & tire rotation. I was given a clean bill of health for a road trip. I refuse to pay anything for a flaw in their design, especially being a dangerous safety issue.

Filed complaint few months back, 10985979. Sudden loss of power. Started to happen again, this time it happened around 15 times in a 200 mile period. Happened during all driving conditions, city and highway, from a stop to highway speeds. No warring just full loss of power. Shut truck off, restarted and ran normally for 6-10 miles then would shut down again. After the 3rd time a check engine light came on. Drove to the nearest ford dealer. They ended up changing the throttle body assy due to a failure of a internal component.
