What Causes the Buzzing Sound After a Car is Turned Off?
1 Answers
It is normal for a car to produce a buzzing sound after being turned off. This could be the sound from the turbocharger, or it might be an unusual noise from the automatic parking system engaging when braking. The correct sequence for turning off the car is: Press the brake to ensure the vehicle is completely stopped, shift the gear to N (Neutral); engage the handbrake and shift to P (Park), then release the brake; promptly turn off any unnecessary electrical devices in the car; check that the gear is in P and the steering wheel is straightened. Precautions after turning off the car: Avoid using electrical devices after turning off the engine; turn off all equipment before exiting the car; disconnect the negative terminal of the battery if the car will not be used for an extended period.
