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. *tr
