Parasitic drains occur when components continue to consume power even after the engine is off. Over time, this can deplete a new battery.

Bad Battery Cables

Damaged or corroded battery cables can prevent the proper flow of electricity, causing the car to die despite having a new battery.

Faulty Ignition Switch

If the ignition switch is malfunctioning, it can interrupt the power supply to the ignition and fuel systems, causing the car to stall.
