Hyundai Ioniq 5 owners have been experiencing a mysterious 12-volt battery drain for no apparent reason since July 2022. This issue has left many owners stranded, unable to access their cars or start them. Fortunately, Hyundai has identified the causes of this problem and has implemented some solutions.
The main cause of the 12-volt battery drain is “overactive unauthorized Bluelink use by 3rd party apps that is waking up the car too often.” This means that third-party Bluelink apps are requesting information from the Ioniq 5 too frequently, causing a significant draw on the battery until it goes to sleep. To combat this, Hyundai has limited Bluelink server traffic to 20 transactions per day and blocked certain problematic unauthorized apps.
The second cause of the 12-volt battery drain is something Hyundai calls “EV Light On with DTC P1A9096 ICCU related.” To solve this issue, the Integrated Charging Control Unit (ICCU) and ICCU fuse have to be replaced. In some cases, the Power Relay Assembly (PRA) in the EV battery may also need to be replaced. Hyundai has stated that this issue is not related to an Inverter Coolant Low Warning light on, which only applied to vehicles before 4/23/21 Production.
