Due to a design flaw, the car's computer system cannot accept an indication of more than one digit in the "age" entry. For this reason, the electric high voltage battery stops working when the car approaches 10 years of age, causing a serious and dangerous hesitation in the drive train when starting from a dead stop creating a very dangerous driving condition, especially when making a cross-traffic turn. Repeated requests from my ford dealer to ford motor company for an explanation of how to fix this problem were unsuccessful. My letters to ford senior management have gone unanswered for several months. I have since learned how to reset the "age" data, and my dealer has followed the instructions to eliminate the condition. Ford should be required to issue a recall for correction of this known design flaw.

The vehicle no longer operates in electric mode, using the high voltage battery to power the electric motor. This is a major safety concern since there is no assist from the electric drive motor. When accelerating from a dead stop, there is a significant lag before the gasoline motor engages and provides enough power to move the car. This is especially pronounced when making a left turn against traffic.

The 2010 ford fusion hybrid keeps going into "limp" mode even on the highway. This causes power loss and loss of acceleration. This can be at anytime. This keeps happening more and more and ford does not know the cause or resolve.

The car stopped while driving through the free way@55 MPH. Do not accelerate. The engine vibrate and car shaking. After turn off and turned on the engine few times, the car was performing fine. The dealer checked. No malfunction code was detected. They told that 95% it is due to the clogging of electronic throttle valve. So replaced. I asked and they showed the old one. I observed no clogging or grease on the valve. It was clean. This parts/or throttle valve system was functioning. The car has 85,000 mile.I spoke to ford about this safety issue.

Starting july 2017 I noticed that my the gasoline engine of fusion hybrid had developed a noticeably "rough" idle when it came on. It also ran "rough" and had an uneven throttle response. A yellow wrench would also appear occasionally on the display panel. The owners manual indicated a "throttle control/powertrain malfunction"and recommended contacting the authorized dealer. Bill collins ford in louisville ,ky checked and ran diagnostics but could not find anything wrong. On september 25, while driving to work in the morning the car experienced a sudden drastic drop in speed going from about 65mph to about 30mph. The car become unresponsive to the throttle. The gasoline engine had completely shut down and the car was limping along powered by the electric engine. Both the wrench and the check engine indicators lit up on the display and stayed on. Luckily I made it off the expressway and got to work. This was very scary and I was lucky to not be rear ended or crashing the car. When I attempted to restart after about three hours the the gasoline engine came back on but with a very "rough" idle. I was able to drive the car to the dealership. This time they diagnosed a problem with the electronic throttle body and for about $600 replaced the etb, cleaned the "mass air flow sensor" and "reprogrammed the computer". However, the the car continues to idle "rough" and has poor throttle response, which were issues the car had leading into the loss of power on the expressway. The dealership does not know how to fix this problem and claims to be in touch the ford factory engineers to find a solution. There is no response so far. Searching on the internet, I understand this is a known issue with ford fusions particularly the 2010 model year. The federal safety agency mandated a recall problem for 2010 fusions gasoline engines but not hybrid models!

My ford fusion hybrid 2010 stalled without any warning in the 5th lane of I-85 in atlanta. My wife, the responding police officer, and myself were in grave danger because of this. We were blessed and fortunate that an officer happened to be very close when our car suddenly died in the middle of the interstate. The interstate traffic was heavy - but slow moving due to construction. The officer responded - literally - within seconds since he saw what was happening. He placed his car behind ours with his lights flashing. The the officer and I had to push my vehicle off to the side. We were all in grave danger! As the officer was calling for help and a wrecker, my car suddenly began working after several minutes. This was an extremely dangerous situation. I then researched this problem on the internet after I returned home only to discover that many other ford fusion owners have experienced the same problem of random stalling. This is totally unacceptable! What is ford waiting for to recall this vehicle?? I have no confidence driving this car now. It's only a matter of time until a tragedy occurs because of this. (if it hasn't happened already)
