Symptom: The battery is dead after the car sits for a day or two, sometimes with warning lights after a jump.
Likely causes
- VSA module drain. Honda's bulletin describes the stability control unit staying awake, especially when the electronic parking brake is applied within a few seconds of shutting off. The fix is a VSA software update plus a sensor recalibration.
- A tired battery from repeated drains.
Cost
The software is typically covered by warranty or done for a small labor charge.
