    Buzzing noise when cold which goes up and down with engine RPM

    '17 Cruze LT, automatic, built Dec. '16, 13.5K miles. Realllllly getting more noticeable. Last time I posted about this was told it was the DI, but geez, it didn't do this for the first nine months I owned the car.

    Any TSB's for this? Really don't feel like driving the twenty miles round trip to and from the dealer, leaving the car for a day, and hearing the dreaded 'Could Not Duplicate' or 'No code thrown; normal operation'.

    Thanks.

    It's from under-the-hood, if I wasn't specific in the original post.

    It's the direct injection high pressure fuel pump that is camshaft driven. Mine's always done it when cold outside. DI cars just make a lot of noise in the cold.

    I can grab a video if it'd help, but I suspect we're talking about the same noise.

    Loudest since the nine months you have owned the car....have the recent temps where you live been the coldest in those nine months?

    I notice it a fair amount with my car during the cold spells of winter. This morning at 12 degrees, I was a bee buzzin' down the road until I got to the interstate.

    I bought the car in Jan. '17. Didn't notice the noise in the cold weather until late fall or so--the second winter in the car. But thanks for the input, both of you guys. I guess I live with it.

    Mine makes this exact noise. Thanks for enlightening me. I thought it was an intake noise or something. Cold makes sense as it has surely been that here.

    I've had my 2018 for a month after totaling my 2012. I didn't hear that noise until about a week ago. It's pretty loud when it's cold. After I jump on the highway I don't hear it. It's less noticeable when it's warmer outside. When I started hearing it I wasn't to happy. I even have a appointment for this Friday, but I may cancel it now.

    Yep, ~45-55 starting temp, it isn't that noticeable. Gets louder the closer you get to freezing or below. And yep, goes away with some engine heat.

    We've got some very cold weather here in winter and we had some -20 celcius very often all winter long and I never heard this noise. We didn't get 45-55 fahrenheit yet lol. Maybe because it's too cold and no in between?

    I hear it now even when I start it and it's 80 degrees outside. It's definitely a change from the entire first year I drove the car. Goes away quickly and isn't as loud as when it's cold, but if I'm hearing it now, I'm thinking it'll be noisy, big-time, this coming winter...sigh.

    Just wondering...anybody on the forum get TSB's as they are issued for the second-gen?
