The Porsche Cayenne may lose charge from the battery daily due to several factors, such as parasitic drain from electronic systems like alarms, infotainment, or onboard computers that remain active even when the vehicle is off. Additionally, frequent short trips can prevent the battery from fully recharging, leading to gradual depletion. Cold weather can also hinder battery performance and capacity. Regular maintenance and checks can help identify and mitigate these issues.
