      I have a 2022 Buick Encore GX with the 1.2 litre engine, After sitting overnight or for a long period of time I get a noise from what seems to be an exhaust leak for about 30 seconds then it goes away. I’ve had it to my local dealership but they can’t diagnose anything.
      Just wondering if anyone has had the same issue.

      Thank you in advance.
