What are the possible factors for abnormal noises when a car is driving on a bumpy road?

[OElena]

There are 7 possible factors for abnormal noises when a car is driving on a bumpy road: 1. Dashboard noise: This occurs most frequently. When we drive out, we often place parking permits, sunglasses, etc., in the lower left corner of the front windshield, which can cause a crackling sound as the car moves. This issue is easily resolved by carefully checking for any foreign objects. 2. Glove compartment noise: If the glove compartment is stuffed with too many items, regular cleaning can effectively solve this problem. 3. Seatbelt buckle noise: The passenger seat often produces a metal knocking sound because the seatbelt buckle wasn’t properly secured after the passenger exited the car. Parking and adjusting the seatbelt will naturally eliminate this noise. 4. Window noise: If advertising cards or similar items are inserted into the window and not removed before raising or lowering the glass, the small card may get sucked into the door, occasionally causing a fluttering sound. Regularly checking for foreign objects in the window can prevent this. 5. Trunk noise: Too many items in the trunk can cause noise, and removing excess items will solve the problem. 6. Dome light noise: If the screws of the dome light are not tightened properly or the light is not positioned correctly, it can produce noise. 7. Loose wiring from installing devices like dash cams: If the wiring near the dash cam is loose, simply securing the wiring in the proper position will resolve the issue.
