Two problems related to cruise control have been reported for the 2010 Ford Fusion Hybrid. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2010 Ford Fusion Hybrid based on all problems reported for the 2010 Fusion Hybrid.
While driving on the highway 70 mph speed limit the car stop accelerating and slowed down to the equivalent of driving in "cruise control" at 30 mph. A yellow wrench warning light turned on. Took car to Ford dealer and they felt problem was consistent with a throttle part problem and they recommended replacing the part which I did and fixed the problem. Of note, by the time I had the car towed to Ford dealer (day after incident) the warning light was off and Ford dealer said that the car system had no record of event.
Driving on highway w/ cruise control engaged at 65 mph speed. Suddenly car loses complete acceleration & propulsion ability, resulting in car to slow down rather suddenly. I was able to pull onto off ramp in my case, but if I was in a different location, I would have definitely been in a very dangerous situation/serious accident. I turned off vehicle and restarted the vehicle a few minutes later. Proceeded to the highway again, experienced the problem again, this time I was only able to pull over to the left shoulder, which was quite narrow to begin with. "wrench symbol" appeared the second time and stayed on with check engine light on. Car was unsafe to drive further. The check engine trouble shooting codes I had were p2111 and p2112. Cause of this issue is known to Ford motor but they refuse to include hybrid cars in their "consumer satisfaction program 13n03". Throttle body control module senor, including the entire assembly is defective as Ford has agreed to replace this on millions of cars across various model years, including the fusion 2010, but not Fusion Hybrid versions. Ford states they will not repair problem that I experienced recently under this established program which NHTSA was proponent for. The defective part in question is the throttle body assembly and sensor which is no different than the part in the non-hybrid version for the same model year. Real hazard to driver and I was lucky that I was not rear ended as a result or in a serious car accident from this known defective part. Ford motor must be required to notify all affected owners who will/have experienced this problem to have it repaired at their expense, as this is a serious safety issue that must be taken seriously given number of vehicles that are involved that will experience this. I experienced this at mileage of 75k but I have read that others have had this happen at much lower mileage.
