There are only two ways a car can unexpectedly shock someone, and the sources and solutions are different for each. A common reason people get a shock from their car is static electricity. This can happen when you touch metal on the car, although it is more common after the vehicle has been driven.
How to ● Avoid Getting Static Shock Effect ● from Your Car
The other way to get electrocuted by a car is to inadvertently act as a ground for the ignition system, which can be painful and dangerous. The other electrical systems in most cars are not dangerous or capable of shocking you, with the exception of electric and hybrid vehicles.
When you touch a car door handle, door, or other metal surface and feel a shock, the cause is a sudden discharge of static electricity. This is the same phenomenon behind the trick of sliding your feet on a carpeted floor before touching another person to startle them, or magically sticking a balloon to something after rubbing it on your sweater.
Static electricity occurs when an electrical charge builds up in one substance due to friction against another material. In the case of the foot-shoving trick, the two materials are carpet and your feet. In the case of a car that constantly gives you a jolt after driving, the materials are usually your clothing and the car seat, which rub against each other as you drive.
