My 2017 Cruze Premier Turbo has an odd issue that no mechanic has been able to figure out. When accelerating up a slight incline going from 45 to 70 mph there is a "chirp" that sounds like is coming from the front of the car. You can hear it when the radio is off. It is very faint and only lasts about 2 to 5 seconds then stops and may or may not do it again but the car does it every day. I've had Chevrolet look at it as well as multiple mechanics. They all say nothing is wrong. The car has 60,000 miles, I've had all bearings, ball joints, etc checked. I've even replaced the tires. I've never missed any oil changes. Any idea what might cause this? Possible hole in turbo? Thanks for the help!

Whom are you yelling at?

Two reasons for a chirp come to mind. One can be caused by a failed PCV valve that pressurizes the crank case and blowing the front seal.

The other is a loose spark plug / bad resister spring.

There are other causes as well, but those should be enough to investigate for now.
