It appears that there may be a trend of premature ima battery failures for this vehicle and should be investigated. On our brand new 2010 Honda Civic hybrid with less than 952 miles and less than 4 months of use, the ima and check engine lights came on. Ima battery - premature battery module deterioration (code P0A7F.) was determined to be the cause of ima and check engine light. The battery module was replaced by the Honda dealer. Ima and check engine light came again in October 2013, less than 3 year of use. Took it to the Honda dealer. They checked it out and replace the battery module on 10/31/2013. The ima code was the same, P0A7F high voltage battery deterioration. The mileage was 46,084. Two ima battery failure in less than three years appears to be excessive. The original warranty on ima battery module is 8 years, 80,000 miles (for Ohio) as listed in the owner's manual. For some states, it is 15 years, 150,000 miles. Although, both batteries were replaced under original warranty, it appears that there may be a trend of premature battery failures for this vehicle and should be investigated by appropriate agencies and the car company. Safety as a result of loss of power without the battery assist, fuel consumption (mpg), replacement costs of batteries and time required for the repair/replacement are the main concerns. The warranty info on the replacement is sketchy and unwritten.

On the 7/28/2013 I was driving normal highway speeds of app 70mph in my 2010 Honda Civic hybrid when suddenly every dash light came on and the engine died causing the power steering to freeze up. The resulting chain of events nearly caused me to wreck the vehicle but I was able to perform a controlled stop and exit the freeway. Approximately 10 minutes later I was able to restart the vehicle and continue on. When I took it to the dealership a few days later and have the problem diagnosed it was determined that there was a bad cell in the battery which in turn was confusing the vehicle computer resulting in the shutdown of the vehicle engine. Had the freeway not been straight at this particular point undoubtedly this would have resulted in a fatal accident. This problem should be investigated and resolved before this results in a fatal accident. Once the battery was replaced I had no more issues in regards to the engine shutting down prematurely.
