2022 Toyota Models Battery Discharge TSB

Symptoms of Battery Discharge

Owners of 2022 Toyota models, including the Toyota Camry, might experience issues related to a discharged battery. This can manifest as difficulty starting the vehicle, dim lights, or other electrical component malfunctions. Reduced battery performance and service life are common outcomes if the battery's State-Of-Charge (SOC) is not properly maintained.

Diagnosis and Trigger Conditions

Battery discharge in a stored vehicle, such as a new 2022 Toyota Camry awaiting delivery, can be influenced by several factors. These include the length of the storage period, ambient temperature, and parasitic drain from vehicle systems. The overall battery load also contributes to how quickly a battery loses its charge.

Important Warnings Regarding Battery Warranty

Toyota has a clear policy regarding battery warranty coverage. The manufacturer does not provide warranty coverage for batteries that are discharged or fail due to a lack of maintenance. This policy highlights the importance of proper battery care, especially for vehicles in storage or those recently purchased.

Owner Action and Dealer Responsibility

While battery maintenance is crucial, it is primarily the dealer's responsibility to ensure the auxiliary (12V) battery maintains its specified State-Of-Charge (SOC) while the vehicle is in stock. To prevent customer service concerns related to an undercharged battery during the initial weeks of ownership, dealers are instructed to test the 12V battery and recharge it if necessary. This check and recharge must be completed no more than 48 hours before the vehicle is delivered to the customer.

If you experience a Toyota Camry battery discharge issue shortly after purchasing your 2022 Toyota, it is advisable to contact your dealership. Understanding the conditions that lead to battery discharge can help owners ensure their vehicle's battery operates optimally.
