What Causes the Abnormal Noise in the New Jetta on Bumpy Roads?
2 Answers
Suspension System Abnormal Noise: The condition of the car's shock absorbers directly affects driving comfort and safety. Whether they need to be replaced depends on mileage or service life, with the lifespan of ordinary shock absorbers reaching up to 100,000 kilometers. If there is obvious abnormal noise when driving on bumpy roads, it is usually due to damaged or leaking shock absorbers, which require replacement. Braking System Abnormal Noise: Braking noise can occur in various types of vehicles, sometimes even in new cars, especially in low-temperature environments. Most performance cars use high-temperature brake pads with a large friction coefficient. If the temperature is not reached, abnormal noise will occur, which can be resolved by replacing the brake pads.
My new Jetta keeps making strange noises on bumpy roads, which is really annoying! Based on my experience, it's mainly an issue with the suspension system. If the shock absorbers are worn out, they'll clunk when going over potholes; also, those ball joints and bushings, once worn and loose, will make friction noises when vibrations get intense. Additionally, if the springs are too soft or deformed, causing unstable support, they can also create noise. Incorrect tire pressure or loose wheel hubs can also cause squeaking sounds when driving over bumps. I recommend paying attention to the source of the noise while driving. The simplest way is to check if the shock absorbers are leaking oil or if the ball joints are loose. When the noise is obvious on bumpy roads, it's best not to drive too fast to avoid increasing wear. If you can't identify the cause, go to a 4S shop for a comprehensive chassis inspection—safety first! Fixing these minor issues promptly will make your car more reliable and durable.
