A few weeks ago, my mom’s car started making a buzzing noise. It’s hard to describe, but it sounds a bit like wind noise. It doesn’t happen all the time, and it stops when she starts braking. We’ve taken it to the mechanic, but they haven’t been able to pinpoint the issue. They initially thought it might be the brake pads or low pressure. They cleaned the brakes and added air to the tires, but that didn’t help, and the noise seems to have gotten louder.
My dad is planning to take the car back in, and we really appreciate everything the mechanics have done so far. I’m just hoping for some outside-the-box suggestions on what it could be, as I want to ensure my mom is safe while driving.
There are far, far too many possible reasons a car might buzz to list here, especially since we can’t hear it. Many mechanics have listening tools that can help pinpoint a noise if you can describe when and where you hear that noise.
And given it is a '17 Nissan with a CVT I’d be changing the transmission fluid if it has not already been done since the car likely has over 70,000 miles. Nissan’s CVTs need to have the fluid changed regularly… I think the manual says every 60K miles. I’d do it more often considering the cost of a new transmission. May have nothing to do with the noise or everything to do with the noise. Good Luck
This sort of problem is best addressed by a shop tech test driving the car with the owner riding along. The owner might do a few experiments beforehand to try to narrow down what causes it to get louder, and what causes it to diminish, and what part of the car seems to be producing the loudest noise.
