Why does the car make a buzzing sound with a resonance feeling?

[CollinFitz]

Car buzzing with resonance feeling is due to exhaust pipe deformation or tensioner pulley wear. Introduction to Exhaust Pipe: The exhaust pipe is part of the engine exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter for controlling engine pollutant emissions is also installed in the exhaust system. The exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe. Impact of Exhaust Pipe Emissions: If the angle of the exhaust pipe is bent towards the sides of the car, the exhaust gases emitted while driving can cause thermal airflow impact injuries to pedestrians. Additionally, car exhaust contains unburned atomized oil residues, including pollutants such as sulfides and carbides, which can cause personal harm to humans.

Last month while driving on the highway, my car suddenly started buzzing loudly, and I could even feel the vibration through the steering wheel. My old car usually runs fine, but once the speed hits 80 km/h, the whole cabin feels like it has a subwoofer installed. After inspection, we found the issue was with the dynamic balance of the left front wheel—there was a lot of mud stuck on the inner side of the rim. The aging engine mounts were also a hidden problem; with the rubber pads cracked, the engine vibrations were directly transmitted to the chassis. The most dangerous was when the driveshaft universal joint came loose—the mechanic said if we had discovered it any later, it might have fallen apart on the road. If you often feel numbness in your feet during daily commutes, it's advisable to first check the tire wear condition.

The buzzing noise is particularly noticeable when driving on the highway, right? I can relate. Uneven tire tread wear can cause resonance at specific frequencies, especially when the tire pressure is too high. During one maintenance check, I found a broken exhaust pipe hanger, and the entire cabin floor vibrated between 40-60 mph. After the engine mount rubber aged, I could even hear the plastic parts on the dashboard rattling at idle. If you've modified the rims, be extra careful—incorrect offset can lead to abnormal bearing stress. It's recommended to rotate the tires regularly and inspect the chassis rubber bushings every 20,000 kilometers.

After the repair of my car's driveshaft, a humming noise appeared because the mechanic forgot to tighten the flange bolts. Now driving feels like sitting on a massage chair, especially noticeable at 60 mph. Actually, an exhaust leak can produce a similar effect, particularly when the muffler rusts through in older cars. A couple of days ago, my neighbor's car had a rattling door panel, and upon inspection, it turned out to be a loose window regulator bracket. When these parts become loose and resonate with the car body's frequency, the humming noise becomes particularly annoying. Remember to secure any loose items in the trunk as well, as even rolling water bottles can cause resonance.
