What causes the buzzing sound and resonance in the Honda CR-V?
2 Answers
crv buzzing sound and resonance are caused by tensioner pulley wear and tensioner pulley wear. Details are as follows: Tensioner pulley wear: The function of the tensioner pulley is to tighten the engine belt, preventing the generator and power steering pump from slipping. Due to prolonged pressure and high-speed rotation, the bearings inside the tensioner pulley are prone to wear, resulting in noise and resonance. When it is confirmed that the buzzing sound and resonance are caused by the tensioner pulley, the engine mount should also be checked, as the engine mount helps reduce the vibration and noise generated by the engine. Tensioner pulley wear: In most front-engine vehicles, the exhaust pipe extends from the bottom of the car to the rear. When driving on rough roads or if the chassis is hit, the exhaust pipe can easily dent or deform. A deformed exhaust pipe increases exhaust resistance, leading to a buzzing sound and resonance.
My Honda CR-V also had a similar buzzing noise and vibration issue before. Whenever I accelerated, the whole car would buzz, and the steering wheel would shake violently, making the drive uncomfortable. After checking, I found that the main causes are usually unbalanced or worn tires – this tends to happen if you haven’t changed tires for a long time or frequently drive on rough roads. Additionally, it could be due to loose bushings in the suspension system, which amplifies the car’s resonance; or worn engine mounts failing to absorb vibrations, allowing noise to transmit. If the brake discs are uneven or rusted, they can also produce a buzzing sound at high speeds. I recommend first checking the tire pressure and wear condition – a simple adjustment might solve it. If that doesn’t work, take it to a repair shop for a professional inspection of the suspension and drivetrain to prevent minor issues from turning into major repairs. Car resonance isn’t just annoying; it can also affect steering control and safety, so addressing it early brings peace of mind.
