This behavior is not normal. Some cars have a bulb failure indicator that will cause a quick blink when a bulb is not functioning properly. However, on your car, this can actually be a symptom of a faulty turn signal relay. The relay is responsible for controlling the flow of electricity to the turn signals, and if it is not working properly, it can cause the turn signals to blink abnormally.
If you notice this happening, it is important to have the car checked by a qualified mechanic to determine if the relay needs to be replaced, If left unrepaired, a faulty turn signal relay could eventually lead to the turn signals not working at all, which is a safety hazard.
