2015 Tahoe LTZ faint chirping sound coming from rear while applying short accerlations.
I bought a brand new 2015 Tahoe LTZ 2wd and love it, however after about 6 months of owning it and 8,000 miles, I started hearing this weird chirping sound, almost like a high pitched squeal or whistle that goes away right after, so the chirp is like a second, and happens consistently when apply about 20-30 % on the gas pedal. This is truly annoying and is driving me nuts. Anyone else out there experiencing this issue? I currently have my Tahoe at the dealer and their first response was like 'uh.. I don't know....'
Had an 06 GMC Yukon in my shop some time ago and it had a similar noise just as you would take off from a stop, would only do it briefly, I finally found it was in the park brake shoes clearance, they were just slightly touching the park drum just enough to set up a squeal or squeak, clean the shoes and park drums and backed the brake off just a little and it went away. I don't know if that is the same thing your having but I'll past it along to you.
Take it to the dealer before you mess with it. Its still under warranty.
Mine does the same thing. Have they told you what it is?
