After coming to a stop and the auto idle-stop feature engages (engine shuts off), the vehicle may not automatically restart when the brake is released. The driver must manually restart the engine, which can be alarming in traffic. The issue is related to starter motor or battery management software.
Honda issued TSB 23-008 to update the idle-stop control software. In some cases, the starter motor or 12V battery may need replacement if they have degraded. The software update is typically free under warranty.
Est. Cost: $0 for software update; $200 - $500 for starter/batteryStarter Motor Failure in Cold and Wet Conditions
The engine may fail to crank on initial startup after precipitation and sub-freezing temperatures. Water can enter the starter motor housing and freeze, preventing the starter from engaging. The vehicle displays no-start symptoms but all electronics function normally.
Honda issued a service bulletin addressing water intrusion into the starter motor. The dealer may replace the starter motor with an updated design that includes improved sealing, or install a protective shield.
