Yea. But the whining noise is very audible in the interior and it?s really startiung to bother me. Anyway it could be replaced by powertrain warranty?

It's not normal. Sounds like a turbo failure, but I've seen leaks cause whines like this before. It's covered by warranty.

I do hear it but it probably wouldn't be covered as a warranty claim until it fails. How many miles do you currently have on the CRUZE?

Woah turbo failure!? that sounds expensive. I currently have 143k km on it and I am having the diesel particulate sensor replaced and had the NOx sensor replaced.

Ah k. You had me worried there. I?m going in next week to have that diesel particulate sensor replaced and then I?ll let them know about the sound. See what they say.

I constant high-pitched whine at the back of the car would also make me suspect the in-tank fuel pump. If you have an automotive stethoscope or a short piece of hose/tubing and can place it on the fuel tank and it's really loud that would confirm.

Since you bought it used and it has a good amount of mile (kms) on it, did it come with any service or maintenance records? I'm wondering if the fuel filter might not have been changed. You can check in the driver information center (DIC) second screen remaining fuel filter life but that doesn't guarantee it was or wasn't changed.

If you pinpoint that the noise is coming from the fuel tank I'd suggest replacing the fuel filter before taking it to the dealer. If they do diagnostics and determine it's a clogged filter it won't be covered under the powertrain warranty and you might be out of pocket the time for diagnostics.

My fuel filter life in the screen isn?t even close to being zero. And the person said it had an oil change recently. So I don?t think the fuel filter would cause the noise. Idk I?m just starting to worry a lot.

I wouldn't worry too much. Let your dealer figure out where it's coming from, they have lifts and can locate it much faster.

None of us like issues, but if something isn’t acting normal just get it checked out.
