2021 Toyota Models Battery Performance TSB

Understanding Battery Performance in Stored Vehicles

Batteries in vehicles that are stored for periods, such as at a dealership, are susceptible to various conditions that can negatively impact their performance and overall service life. Factors like the duration of storage, ambient temperature, parasitic drain from vehicle electronics, and the battery's inherent load can all contribute to reduced battery health.

To ensure optimal Toyota Camry battery performance and longevity, regular inspection and maintenance of the battery are essential. This proactive approach helps prevent premature battery degradation and ensures the vehicle is ready for use when needed.

Toyota's Battery Warranty Policy

Toyota has a clear policy regarding battery warranty coverage. The manufacturer explicitly states that it "does not provide battery warranty coverage for discharged and/or failed batteries due to lack of maintenance."

This policy highlights the importance of proper battery care, placing responsibility on those handling the vehicle during storage to maintain the battery's condition. Owners should be aware that issues stemming from neglected maintenance may not be covered under warranty.

Dealer Responsibilities for Battery Maintenance

Toyota places a direct responsibility on its dealerships to maintain the batteries of vehicles in their inventory. It is the dealer’s responsibility to ensure the specified State-Of-Charge (SOC) of the vehicle’s battery while it is in stock. This also extends to verifying proper SOC at the time of delivery to the customer.

To prevent customer service concerns related to an undercharged battery during the initial weeks of ownership, Toyota mandates that "ALL dealers should check battery SOC and recharge, if necessary, no more than 48 hours before delivery to the customer." This step is critical for ensuring reliable Toyota Camry battery performance from day one.

What Owners Should Know

If you are purchasing a 2021 Toyota model, it's important to understand the dealer's role in pre-delivery battery maintenance. An undercharged battery at delivery can lead to unexpected issues shortly after purchase, impacting your initial experience with the vehicle.

Ensure your dealer has performed the necessary battery checks and recharging procedures before you take delivery. This helps guarantee optimal Toyota Camry battery performance and avoids potential problems that could arise from a neglected battery.
