Car failed to respond to keypad lock transmitter, and then failed to start 3 consecutive attempts. This same car's previous battery died completely approximately 4 weeks after initial purchase and was replaced just 4 months ago. Car has also had numerous incidents where voice recognition and cellphone blu-ray connection acted erratically or failed completely.
The battery and electrical system frequently goes dead, leaving my family stranded and feeling insecure about the safety of this vehicle. For example, if I sit in the car, turned off, with the key in the ignition (no lights on, no radio, etc. ) the battery will die. I have to have it jumped, or wait hours (without the key in the ignition) for the battery to recharge. I don't feel safe being stranded someplace for hours at night.
Battery died after owning brand new car for about 5 weeks.
Ongoing intermittent problem with battery low warning light and chime. Car gets regular use of different length trips -- but warning often appears when door is opened. Dealer advises that this results from short trips. But that should not apply to our usage. No apparent lack of charge in cold starting car -- so this is possibly a false alarm? but -- do not want to be stranded by sudden battery failure or related problems. Honda needs to fix this -- common complaint appearing in the internet.
