A growling sound in the engine of my 2017 Chevy tracks with 71,000 miles

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. With a noise, it's really important to be able to hear it. So, I would recommend you visit a local shop near you to let them hear the noise. Listening doesn't cost anything typically -- so you can demonstrate and ask for troubleshooting guidance from there. A good technician can hear many noises and know what too expect with them, so consulting one near you is a good idea. The noise could be something insignificant, or could be evidence of a major concern. Too hard to know. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
