What Causes the Abnormal Noise When the 9th Generation Accord Goes Over Bumps?
3 Answers
The reason for the abnormal noise when the 9th Generation Accord goes over bumps is: plastic parts in areas with more components such as the dashboard or interior door panels may produce resonance noise, or friction noise caused by mutual squeezing. Generally, this type of noise will also vary with seasonal and environmental temperature changes. If you want to eliminate this type of noise, you need to disassemble and inspect the parts where the noise is coming from. The 9th Generation Accord was launched in 2013. Taking the Accord 2013 2.0L LX as an example: it is a mid-sized 4-door 5-seater sedan under GAC Honda, with a length, width, and height of 4960mm, 1860mm, and 1480mm respectively, a wheelbase of 2800mm, equipped with a 5-speed automatic transmission, and a fuel tank capacity of 70L.
With over 20 years of experience in auto repair, I've found that the 9th-generation Accord commonly develops creaking noises when going over bumps, mostly originating from the suspension system. The primary cause is aged or worn suspension bushings, as daily driving vibrations on rough roads gradually crack the rubber components, producing squeaking sounds. Secondly, if the shock absorbers are leaking oil and their rebound force weakens, the chassis will make clunking noises when crossing speed bumps. Loose chassis bolts are another hidden danger, as prolonged jolting can loosen certain mounting points over time. I recommend checking the chassis for oil stains or noise sources when parked, and regularly replacing suspension bushings to extend service life. For the 9th-generation Accord, bushings typically need replacement around every 80,000 kilometers—don't delay this to avoid compromising handling safety. In summary, it's best to promptly visit a dealership for a comprehensive inspection of such noises to prevent minor issues from escalating.
I've been driving the ninth-generation Accord for over two years now, and I often hear squeaking noises when going over speed bumps in my neighborhood, which is quite annoying. At first, I thought it was a seat issue, but later found out it was mainly due to loose chassis components, like vibration noises caused by aging control arm bushings. The vibration is more noticeable when going over bumps, and older cars are more prone to this. The inspection is simple: pop the hood to check if the shock absorbers have oil stains or insufficient bounce; you can also tighten the chassis bolts yourself. During regular maintenance, I always ask the mechanic to check these parts—prevention is better than cure. Excessive noise makes driving unstable, especially in rainy weather, which is more dangerous. Better to fix it early—safety first.
