Two problems related to software have been reported for the 2003 Honda Civic Hybrid. The most recently reported issues are listed below.
"takata recall" 2003 Honda Civic Hybrid with ima and engine lights went off. No charge to battery cause the car to malfunctions. Such as electrical steering wheel stop working. Engine lost power and stop while driving on city street at stop side. I changed new diehard 12v battery and also checked and verified the ima battery is good (each cell above 7 volts). I think the car need to update software from Honda. Please help us for the recall to update software. Many people have the same problem and they post their story on youtube.
I drove my car to Honda of san angelo dealership for a recall, a software update campaign was done, I picked up the car and upon driving off the dealership lot, I noticed immediately that the electric part of the hybrid was not working, at all, it was working when I dropped it off and getting 47 mpg. Upon returning to the dealership, the service manager told me not to blame them for having a 9 year old car with 100,000 miles on it. I argued the point, that it was working when I dropped it off, and it isn't now, simple as that and as I drove off, the service manager flipped me off. The car is unusable, I parked it in my garage, and dropped the insurance on it. I plan to tow it to a san antonio dealership, which is a 4 hour drive one way, when I can afford it.
