Is It Normal for a New Car to Make Strange Noises When Driving on Bumpy Roads?
2 Answers
It is normal for a new car to make strange noises when driving on bumpy roads, mainly due to component misalignment, collisions, or electrical sounds. Below are detailed explanations and solutions: Component Misalignment: Gaps, deviations, or shifts between leather and plastic components can cause squeaking noises when squeezed or loosened on bumpy roads. Solution: Identify the source of the noise and use materials like tissue paper or rubber as spacers to block the gaps. Component Collisions: Noises caused by collisions between the car's audio speakers and other components. Solution: Tighten screws to secure the speakers, CD player, or other loose parts. Electrical Issues: Electrical sounds inside the car are usually louder when the vehicle is first started, especially during cold starts when audio, air conditioning, or other devices activate immediately or automatically. Solution: The noise will naturally disappear after the engine warms up or after driving for a while.
I have quite a bit of experience with strange noises in new cars going over bumpy roads. Just last week, while helping a friend inspect a car, we encountered a similar situation—the dashboard of that brand-new SUV creaked when going over speed bumps. In reality, new cars undergo road tests before leaving the factory, but parts can shift during transportation. The most common issue is interior panel clips not being secured tightly, causing plastic parts to rub against each other. Another possibility is wiring harnesses not being properly fixed, causing them to knock against the body when going over bumps. My suggestion is to first check yourself: empty the glove compartment to see if small items like coins are rolling around. If there's a persistent metallic clanging sound, pay attention to whether the suspension system bolts are loose. Don't rush back to the 4S dealership; observe after driving for half a month during the break-in period, as many strange noises will naturally disappear.
