What Causes the Door Seal to Make Noise on Rough Roads in a New Car?
3 Answers
New car door seal noise reasons on rough roads: Door hinge wear: Wipe off surface dust with a cloth or tissue, then apply a small amount of lubricating oil using a cotton swab to repeatedly coat the door hinge and the red-circled area of the door limiter. Open and close the door repeatedly, and repeat the steps of applying oil and operating the door until the noise disappears. Avoid excessive lubrication to prevent contaminating other door parts. If the issue persists, it may be due to wear and require replacement of new hinges and limiters. Door seal aging: Check if the door seal is aging. The seal is a rubber product, so regularly clean dust and rainwater from the seal gaps to prevent aging. Since sand and dust can easily accumulate in the seal gaps, use a brush to frequently clean them, then apply a layer of high-permeability protective agent to prevent seal aging. If the seal is severely damaged or significantly aged, it needs to be replaced with a new one.
I remember being really happy when I bought my first new car, but within a few days of driving on bumpy roads, I started hearing squeaking noises from the door seals, like an old record player. A friend told me that the seals on new cars might not have softened yet or weren't installed tightly enough, causing friction sounds when going over bumps. I first tried cleaning the dust from the seal grooves myself, wiping them clean with a soft cloth and applying some automotive-grade silicone lubricant, which significantly reduced the problem. Later, I went to the dealership for a free adjustment. The technician said minor seal issues are common in new cars and advised not to let prolonged vibrations wear out other parts. Now, I check the condition of the seals every month, spraying some protective agent to maintain their elasticity, preventing potential leaks or dust intrusion, which would be troublesome. New cars always have minor issues during the break-in period, but addressing them promptly brings peace of mind—driving safety is what matters most.
There are several common reasons for the squeaking noise of new car door seals on bumpy roads, such as improper installation, overly hard materials, or gaps causing vibration friction. I suggest that car owners who encounter this issue should not panic. First, manually check if the seals are properly aligned and intact, and look for any signs of looseness. A simple solution is to apply rubber conditioner to reduce the noise—it’s inexpensive and provides immediate results. If that doesn’t work, visit a 4S shop; new car warranties usually cover free repairs. This noise isn’t a major issue, but early treatment can extend the seal’s lifespan and prevent water leakage that could corrode internal components. Additionally, driving slowly on rough roads can reduce vibrations and minimize the frequency of squeaking. Remember, regular cleaning is key—wipe the seals during car washes to keep them clean and free of debris that could cause friction.
