Selected complaints filed with NHTSA by 2010 Ford Fusion Hybrid owners, lightly cleaned up (personal details are redacted by NHTSA).

My 2010 Ford Fusion Hybrid experienced identical symptoms (twice) to those of customer satisfaction program 13n03 however the Hybrid version of the Ford Fusion is not included in the program (Ford claims it does not have the issue). I first had the issue in August 2015. I was driving on I-40 in raleigh, going up a slight hill when I noticed the car wasn't going, it was just decelerating no matter how much I pressed the gas. Very scary on a high speed interstate in the middle lane. The two wrench lights came on. I was able to 'limp home'. When we got to the Ford dealer, the wrench lights were no longer on. The dealer claimed Ford Fusion hybrids did not have the etb problem. We asked them to drive the car around, which they did, and couldn't reproduce the problem. They said there was nothing they could do unless I came in with the problem happening. …

My 2010 Fusion Hybrid began a no-start/stalling condition. It has happened six times now. First occurrence was after fueling at low speed after entering street. Second occurrence was while traveling on the highway at 55 MPH. Third occurrence was while exiting the interstate. Fourth occurrence was at low speed. Fifth occurrence was immediately after refueling while still in parking lot. And sixth occurence was also immediately after refueling just after leaving gas station at low speed. Four of the six occurrences was a failure for the internal combustion engine to start after the electric motor had already began moving the vehicle. The other two occurrences was while coasting. …

First time, check engine light came on when driving on highway but no apparent impact to car's functioning. Took it to the dealer. They said that the surge valve needed to be replaced at a cost of $500 "to start with", but they didn't seem very sure about it so I chose not to proceed. The check engine light had gone back off and the car was driving fine. About two weeks later on a Saturday I was driving on the highway again, at about 65 MPH, when the car seemed to lose acceleration. Standing on gas pedal produced no result. Exited and was able to drive on battery power to pull over. After waiting for about 30 minutes, tried again. Check engine light was back off and car drove normally back home. Took to my regular mechanic first thing that Monday. …

My daughter has her learner's permit and was driving my Ford Fusion Hybrid on a 45 MPH street. The wrench light came on and the car would not accelerate as she was driving up a hilly part of the street. Cars began honking and passing and my daughter became extremely nervous. Thankfully, we were not involved in a car accident but she was quite shaken by the incident. I took the vehicle to the Ford dealership to have it repaired and was advised this was not a recall even though there are several thousand complaints and issues. I had to have the throttle body replaced which is apparently a defective part. I don't understand why there isn't a recall for this defect. I understand the NHTSA considers safety a huge factor when recalling parts. However, the part is clearly defective and has cost consumers greatly. …

When driving on the highway at approximately 70 MPH, the wrench indicator light ("limp home" mode) suddenly started flashing, and the gas pedal abruptly became unresponsivethe vehicle would no longer accelerate and could only coast. The abruptly decelerating vehicle was maneuvered across multiple lanes of traffic to the shoulder and turned off. Upon restarting the vehicle after a minute, it was able to resume normal operation for about 15 minutes, when the problem reoccurred, and the same steps were taken. It occurred again 90 minutes later. Symptoms correspond to other accounts of electronic throttle body issues, but Ford says that the vehicle is not covered under any recalls, extended warranties, or customer safety programs.

I was driving on the highway at 65 MPH when two wrench symbols appeared on the dashboard. Within a few minutes, the car began to decelerate quickly and lost power. I had to pull over to the shoulder to avoid an accident. It is the same issue that Ford has extended the warranty for with regard to the non-Hybrid Ford Fusion model. Also there are many similar complaints that Hybrid owners are reporting on the internet. I do not know why the extended warranty does not apply to the hybrids as it is the same issue. The dealer told me that the throttle body must be replaced in my car and they also have to reprogram the powertrain code.

Driving on city street, speed limit 45, unable to normally accelerate - did so extremely slowly - noticed wrench indicator light and stop safely warning light both on. Car would only accelerate to 40mph despite pressing gas pedal down completely. Could not drive to work as it required highway driving up to 60 MPH and couldn't risk danger of slow or stalling vehicle. Research indicates this is well known to Ford (faulty throttle body) and was partially accommodated with extended warranty (13n03) but otherwise eligible Hybrid vehicles not covered by that program. Dangerous issue + known to manufacturer = eventual lawsuit.

I was cruising along a major urban highway @ 50mph when I suddenly lost the ability to accelerate. Car lost speed and went to 45 then down to 40 and I was unable to accelerate. Luckily traffic was light and I was able to cross the two lanes over to the right and exit the main road and limped along to a stop in a safe area. Dealership had to replace the throttle body and motor. Was not covered by Ford's csp 13n03 which had been issued for a similar problem. Was told the program did not apply to the Hybrid model, and yet it was the same problem described in the NHTSA action number pe 13003!
