What Causes the Honda Accord to Make a Buzzing Noise at High Speeds?
2 Answers
The reasons why the Honda Accord makes a buzzing noise at high speeds: it could be tire noise; or a resonance phenomenon occurring in the body position. Below is an introduction to the Accord: Body dimensions: The Accord is a mid-size car under Honda, with a wheelbase of 2830mm, and length, width, and height of 4893mm, 1862mm, and 1449mm respectively. Powertrain: The Accord uses two engines in total, which are the low-power version 1.5-liter turbocharged engine and the high-power version 1.5-liter turbocharged engine. The low-power version 1.5-liter turbocharged engine is matched with a CVT transmission. The high-power version 1.5-liter turbocharged engine has a maximum power of 143kW, equipped with VTEC technology and direct fuel injection technology, and uses an aluminum alloy cylinder head and block, matched with a CVT transmission.
Last time I drove my Accord on the highway, I also encountered this kind of humming noise. After careful inspection, I found it was a tire issue. When the speed exceeds 80 km/h, uneven tire wear or unbalanced tire pressure can easily cause this kind of noise, especially if the front wheel alignment is off, it becomes more noticeable. However, it could also be due to worn wheel hub bearings—these things tend to hum when spinning fast. I suggest first checking the wear condition of all four tires to see if there's any uneven wear. If the tires are fine, it's best to go to a shop, lift the car, and spin the wheels to listen for bearing noise. Don't underestimate this sound—if left unchecked for too long, the bearings could fail, and the wheel might even come off. Safety first!
