What would cause 2017 honda crv buzzing noise?

If the 2017 Honda CR-V is making a buzzing sound then it could be a couple of things. The AC clutch is slipping, the drive belt is slipping or the air filter is d***y and needs to be replaced. If it is coming from the radio then You have a bad wire and the radio is not connected all the way. This could also result in static. These can range from aggravating to serious, but in any case, You should have them fixed sooner rather than later. The clutch and drive belt will cost You around 600 in total, while an air filter is only about 100 for parts and labor. The radio depends on where the wire is. It won't be pricey, but You may need to hunt to find the issue.
