GTW_w177_dead12VBattery
The 12V battery voltage has dropped below 10.5V for at least 5 seconds. If this alert is present, the 12V battery has likely become damaged through excessive discharge and should be replaced. The root cause of this damage should also be diagnosed and repaired to prevent future occurrences in the new battery.
The flooded batteries used on Model X vehicles are especially sensitive to deep discharge, which can result in failures developing weeks or months later even if the battery looks fine initially.
