On Wednesday, I had my first 2010 Mercury Milan with the CSP. To my surprise, they also did the driver's side airbag recall. So far, the results are excellent, although it's hard to tell the difference between this CSP and the age fix which I did two year ago. Today I had my other Mercury Milan done, but no driver's side airbag replacement (on order maybe next week). Both cars have about 55 thousand miles, and the average mileage was slightly over 38mpg during the summer months with the age fix.

FusionDiffusion, thanks for the update! Do you have a link where I can find "Application Performance Upgrade 22G04 Certain 2010 – 2012 Model Year Fusion / MKZ / Milan Hybrid Vehicles Hybrid Battery Reduced Electric Vehicle Operation BECM and PCM Software Update" so I can show the dealer. Fords should have done this when they came out with the update that resolved this problem.

Thanks for the update. I will wait to get feedback to see how it works. I would assume when they reprogram the modules the new program would completely overwrite the old program and it would assume the car is 10 years. Hopefully this reprogram will take in all the factors needed to make an effective fix. I would think it should consider not only the battery age but the miles driven and the actual condition of the HV battery.

You need the license to implement the change needed to reset the age of the HV battery. Without the license you will not be able to do it. -

I am frustrated that Ford after all the owners complaints and finally recognizing the problem months ago is taking so long to come up with a fix. It would appear that the fix is of low priority. Meanwhile an increasingly number of owners now get lower gas mileage and increased engine wear from the increase engine on time. It appear that all 2010 to 2012 Ford hybrids have this problem. I wonder if the newer models also have this computer programming flaw that will curtail hybrid use after nine years. -

2010 Ford Fusion VIN 4757 Hybrid Electric Vehicle Battery Test Results - Department of Energy Conclusion: The Ford Fusion, with VIN 4757, experienced a 3.8% degradation in battery capacity and stayed below DOE targets for all aspects of the HPPC test over the duration of 160,000 miles of fleet testing. From this result I would assume the 9 year cut-off that Ford did on the hybrid function is much too conservative. Full hybrid functionality could extend for many more years without risk of HV battery problems. https://energy.gov/sites/prod/files/2014/02/f7/batteryfusion4757_0.pdf -

Thanks for the information! It appears Ford may finally do something about this problem. I complained about this to Ford on many occasions since January and I even wrote my Congressman about this issue. He also sent a letter to Ford about this issue. So hopefully Ford will oil the squeaky wheel! -

By now some 2011 Ford Hybrids should be exhibiting the HV barttery / computer problems that the 2010 hybrid vehicles have. If they don't then perhaps Ford became aware of the problem and put in a larger capacity computer that has programming for years beyond ten years. -

Another thing to check is the HV battery level. Most of the time it should be in the middle. If it is at the high (top) level most of the time you do have the same problem as the 2010 vehicles. -

I just spoke to my Ford regional manager. I have two 2010 Mercury Milan hybrid cars with currently 45,000 on each. Before the seven month storage for the airbag recall they were working perfectly. Now they both have problems going into the hybrid mode. The regional manager spoke to my service manager who stated according to the diagnostics everything is working correctly even though the service manager test drove one car and saw the car not going into the hybrid mode. So Ford said they cannot fix the problem. Hopefully the class action against Ford will have good results. -

Glad to read that you got the hybrid functionality of your car working! My question to you is can your car accelerate in the hybrid mode if you press the gas pedal very lightly in speeds under 47mph? Also where does the HV battery indicator stay previous to the repair and now after the repair? On my two 2010 hybrid vehicles both in the winter and summer the HV indicator stays most of the time all the way at the top which is not normal it should be in the middle. Also in the warmer months my cars will start in the hybrid mode and go into the hybrid mode while braking when the car speed is under 47mph. What may cars will not do is go into the hybrid mode when lightly accelerating under 47mph (which it previously did). I have 45,000 miles now on each car.
