1) visors cracked - driver's side does not stay up. 2) hybrid battery light showed it failed - dealership reprogrammed the car fall 2011 and since then the car does not accelerate as well. I have noticed lessened ability to accelerate when merging. 3) two of the doors fail to lock when the car reaches locking speed. One of these is a back seat passenger door where a child sits.
While braking, the car starts to regenerate (charge the hybrid battery) and then a short burst of assist (electrical drive from the hybrid battery) while my foot is on the brake. This happens about twice a week and is extremely dangerous since I sometimes get into stop-and-go traffic. This means that I could be braking and the car will accelerate, possibly hitting the car in front of mine.
2009 Honda Civic Hybrid. Consumer requests immediate replacement of a defective battery pack. The consumer stated the (ima) integrated motor assist light illuminated. The diagnosis indicated a battery condition monitor module intermittent malfunction. The light illuminated again two months later. Although, each visit resulted in electrical repairs with specific code reviews, recalibrations, clearance and resetting, the underlying condition still has not been resolved.

Honda Civic Hybrid has a problem with the battery that the system uses to run the integrated motor assist between the transmission and the engine to assist the gas engine when accelerating. As the battery deteriorates, it does not charge as well, hold a charge and therefore does not assist as well to accelerate, causing a dangerous situation at times to merge with traffic or accelerate from a stand still.
