Engine hesitates from a stop and bucks and jerks while driving. Hard pick-up. RPM's up to max without vehicle acceleration. Feels like transmission slips into neutral. First visit, 5/18/2010 (8767 miles-bought new at 15 miles-10/10)/ presently, July, 2011, car with 22,000 is in for 4th return to dealer: 10/2010 car 1 year old, 14,000 miles, local oil repair shop notices both lower ball joints boots split, returned to dealer to resolve. Still hesitating and jerking and bucking, particularly during gear shifts. Second visit, 11/2010 returned for same driving problems. Third visit 6/30/11 service shop notices leak under carriage, returned to dealer. Service manager and I check under carriage, still obvious leak, he told me it wasn't a leak, we both had grease/oil/something on our hands. Refused to extend rental car coverage as car is "completely fixed", left with car, wrote on ticket, "leak still unresolved". returned for forth visit 7/8/2011 admits leak "somewhere". also, sealant around windshield melts and becomes tacky in hot weather (Texas). Had dealer reseal last summer. Now, area is getting tacky again. Will this occur each summer and will seal hold during hard rain?

Traveling at high speed with cruise control on. Applied brake to slow down for traffic, vehicle continued to slow and would not respond when I applied the accelerator. I had to put the transmission in neutral and had to push gas pedal several times hard before engine would respond. This happened twice while traveling from Florida to Canada. I had the Ford dealership in wetaskiwin, alberta, Canada check the vehicle, they could find nothing wrong. I continue to drive the car, but I am fearful that, if it happens again, I could be rear-ended.

While traveling at highway speed on a 4-lane divided highway, a slow-moving vehicle merged in front of our Fusion forcing a hard braking event (there was somebody coming up from behind in the left lane, preventing a lane change at that instant). The Fusion was slowed down to 50-55 mph as the car from behind passed. This allowed a lane change to avoid hitting the car that pulled in front to begin with. However, in order to keep up with the flow of traffic, 100% accelerator pedal was required. As the Fusion accelerated up to near the original speed, there was a whining sound coming from under the hood, then a violent jolt. This jolt severely shook the car, caused a sudden deceleration and to swerve on the highway. Luckily, my wife was able to keep control of the car. The seat belt grabbed. Had my wife not been wearing the seat belt, she is convinced that she would have been thrown into the steering wheel. The car was taken to a nearby Ford dealership. No problems were found. (however, a fault code specific to hybrid vehicles was logged in the PCM memory.) this appears to be a continuation of the transmission problems this car has been experiencing since the day after I purchased the car in August, 2010 - and Ford has been unable to correct. This vehicle has been into the Ford dealer numerous times for transmission issues. The car is now at my local dealership.

This vehicle was recalled for a known transmission issue in June 2010. Ford appears to have reprogrammed the computer to change shift points. Shifting is smoother but still it does not perform like a normal Ford transmission (I have driven Ford since 1964). Time out of service was one day. Jan 20, 2011 while my wife was driving at approximately 55 mph, the transmission completely disengaged. There was no power and car had to coast to a stop on the side of the road. After sitting for the amount of time that was required for me to reach her I was able to drive the vehicle to the dealership about four miles away. The transaxle seal was leaking and fluid was low. The required parts were on backorder at Ford and we had to wait for parts. The vehicle was returned on Jan. 31, 2011 (11 days out of service). On Feb.12, 2011, the vehicle was being driven by me at approximately 55 mph when the transmission again disengaged. I had to coast to the side of the road and call Ford road service for a tow. I parked the vehicle and turned the ignition off. I tried to start the engine to record the mileage and the engine would not run, acting as if the timing was completely out of sync. It bucked and missed fired as if the timing was not correct (I had experienced this once before when starting the vehicle one morning in late Sept. 2010 but had not experienced it since that time thought we had gotten some bas gasoline). On both occasions when the transmission has disengaged, the check engine, maintenance required and transmission service required was displayed on the dash by the computer but the dealer claims there was no error code recorded by the computer system. The transmission disengaged again ant highway on March 11, 2011. This is well documented on the web and will cause a death if Ford does not correct the problem.

This vehicle has been serviced nine times at dealer with symptoms of transmission slipping between 2nd and 3rd gear. It continues to do the same with harsh transmission engagements, slipping causing RPM's greater than 5000. A vehicle event recorder was installed into the vehicle and problem identified. Valve body has been cleaned, new transmission solenoid, "re-flashed" 2 times with no changes. Ford customer service involved from beginning. At one point received call from customer service district manager stating it is "normal" for the car to shift this way and there is no problem even after the problem has been identified. This continues to be a huge safety issue as the car slips at any time in any traffic. There has not been a solution to fix this problem nor any guarantee. Something has to be done to fix the problem that affects many owners with this 6 speed automatic transmission. Previous complaint ODI 10369166.

I purchased my vehicle on May 15, 2010. The vehicle began to stall almost 1 month later at 2100 miles. I was coming to a stop at a red light when I noticed that my vehicle had lost all power when I began to apply the brake. I took the vehicle into the dealer and they told me that they were not able to replicate the problem and no codes were showing up when diagnosed. After the first time the vehicle stalled on me I started to notice an acceleration problem prior to the vehicle stalling again. It feels like the vehicle is not shifting gears correctly when I'm pressing the gas for acceleration. The vehicle has trouble accelerating properly and I fear that I may get rear ended. When the vehicle stalls it does not give me any warning signs and just looses power. I have to turn off the ignition and turn it back on. The vehicle starts up right away like if nothing happened. Meanwhile I loose power in the middle of the freeway or on the street, fearing that I will get rear ended. The vehicle has stalled on me numerous times and each time I take it into the dealer they are not able to replicate the problem. The dealer placed a flight recorder to monitor the vehicle and they still weren't able to capture anything when the vehicle stalled, so they say. I have contact Ford corporation and have notified them of the problem but they are not working to fix the problem. They keep changing me from dealer to dealer and they have not sent out a Ford technician as promised to look at the vehicle. This is a huge safety concern that Ford is not addressing. I have put in numerous calls to Ford corporation and they have not fixed the problem to this day.

While under normal driving conditions and habits, we experienced a complete instrument cluster failure in our 2010 Ford Fusion hybrid this past Saturday, Feb 20. 2010. During the same incident we experienced a symptom of diminished power while accelerating as well as overly sensitive and /or mushy brakes. There have been other reported instances where the brake system has glitched as well during regenerative braking causing an abrupt application of hydraulic system over riding the regenerative system, brake system continues to have issues even after recall repair reprogramwas performed. We have had several instrument cluster glitches while driving the vehicle since purchase date of October 26, 2009. First incident was reported October 27, 2009. Several. Instrument cluster resets while driving since purchase date. First incident reported same date as previous.. on February 22, 2010 car stalled for no reason while driving 45mph in traffic to dealership to have instrument cluster and other issues addressed. Restarted when car came ro a complete stop and placed in park. Car is at dealer now and no codes were reported in systems. Ford engineers state that with no codes reported there can't be any problems.
