2024 Toyota Hybrid/BEV Battery Maintenance TSB

Why Battery Maintenance Matters for Stored Vehicles

Toyota has released a manufacturer communication, TSB 10252255, to address the importance of battery maintenance for 2024 hybrid (HV) and battery electric vehicles (BEV). Both types of vehicles are equipped with a Hybrid Vehicle (HV) battery and an Auxiliary (12V) battery. When these vehicles are placed in storage, the State-Of-Charge (SOC) for both batteries will naturally decrease over time. Proper maintenance is essential to prevent the auxiliary battery from becoming fully discharged during storage.

Toyota's Battery Warranty Policy

Owners of a 2024 TOYOTA Camry or other affected models should be aware of Toyota's policy regarding battery warranty. Toyota explicitly states that it does not provide warranty coverage for batteries that become discharged or fail due to a lack of proper maintenance. This policy underscores the critical need for consistent battery care, especially when a vehicle is not in regular use.

Dealer Responsibilities for Stored Vehicles

The manufacturer communication clarifies that it is the dealer's responsibility to ensure the specified State-Of-Charge (SOC) of a vehicle's battery is maintained while the vehicle is in their stock. Furthermore, dealers must ensure proper SOC at the time of vehicle delivery to the customer. This ensures that vehicles are delivered with batteries in optimal condition, ready for immediate use.

What Owners Should Know

If you own a 2024 Toyota hybrid or BEV model, such as the 2024 TOYOTA Camry, and your vehicle has been in storage, it is important to confirm that appropriate battery maintenance has been performed. This proactive approach can help prevent issues related to battery discharge and ensure your vehicle's batteries remain covered under warranty. The TSB emphasizes performing maintenance service for both the HV battery and the auxiliary battery.

Owner Action

If you are purchasing a new 2024 Toyota hybrid or BEV vehicle that has been in dealer stock for an extended period, or if your vehicle has been stored, consider discussing battery maintenance procedures with your dealership. Inquiring about the battery's State-Of-Charge history and the maintenance performed can provide peace of mind and help avoid potential battery-related issues down the line.
