2023 Toyota Camry Hybrid Battery Maintenance TSB

Why this matters

For owners of 2023 Toyota Camry and other hybrid vehicles, understanding battery maintenance during storage is crucial. Hybrid vehicles are equipped with two types of batteries: the main Hybrid Vehicle (HV) battery and an auxiliary (12V) battery. Both batteries can gradually lose their State-Of-Charge (SOC) if the vehicle is stored for an extended period. This TSB highlights the importance of proper maintenance to prevent discharge, which can lead to battery failure and potentially impact warranty coverage. This guidance is particularly relevant for the 2023 TOYOTA Camry manufacturer_communication.

Symptoms of a discharged battery

If your 2023 Toyota Camry has been in storage and its batteries have discharged, you may experience issues such as:

• Vehicle failing to start
• Warning lights on the dashboard related to the hybrid system or 12V battery
• Reduced electrical system functionality

These symptoms indicate that the State-Of-Charge (SOC) for either the HV battery or the auxiliary (12V) battery has fallen too low.

Trigger conditions

The primary trigger condition for battery discharge is vehicle storage. When a hybrid vehicle is put into storage, both the HV battery and the auxiliary (12V) battery will gradually decrease their State-Of-Charge (SOC). This natural discharge rate necessitates proactive maintenance to prevent the batteries from becoming fully depleted. This applies to the 2023 TOYOTA Camry manufacturer_communication.

Important warnings

Toyota explicitly states that battery warranty coverage will not be provided for discharged and/or failed batteries that result from a lack of maintenance. It is the responsibility of the dealer to maintain the specified State-Of-Charge (SOC) of the vehicle's battery while in stock and ensure proper SOC at delivery. Owners storing their vehicles should be aware of this policy to avoid unexpected costs.

Owner action

If you plan to store your 2023 Toyota Camry or other affected hybrid vehicle, it is essential to implement a battery maintenance strategy. This typically involves periodically starting and driving the vehicle, or using a suitable battery maintainer for the auxiliary (12V) battery. Consult your owner's manual for specific recommendations on long-term storage and battery care. If you are purchasing a new vehicle covered by the 2023 TOYOTA Camry manufacturer_communication, ensure the dealer confirms the battery's State-Of-Charge (SOC) at delivery.
