Symptom: The battery is dead after the car sits for a day or two, sometimes with warning lights after a jump.

Likely causes

  1. 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.
  2. A tired battery from repeated drains.

Cost

The software is typically covered by warranty or done for a small labor charge.

DIY or shop?

  • Dealer: the VSA update.
  • DIY: battery test or replacement.

Useful steps

  1. Ask for TSB 17-032.
  2. Until it's updated, wait a few seconds after shutting off before setting the parking brake.
  3. Have the battery tested after a deep drain.
