My 2017 Sierra gas pedal would click when I first got it. I ended up getting the pedal bracket replaced at the dealer and that fixed the issue for me.

I believe the valve was redesigned and may not be as easy to keep open as it was with the older exhaust. I ended up with the same problem with the squeak again, and bought a Borla Atak exhuast system. I like how loud it is, but it probably pisses off the neighbours on cold start in the early morning.

I took my '17 Sierra in for the same thing today. After doing a bit of digging online, I referenced PIT5404D (Dated June 16, 2017) and the techs were able to reproduce the squeak and verify that PIT5404D was the correct bulletin. I'm in Canada, it will take a week or two to get whatever parts necessary to fix it.

When I bought my truck, my requirements were Standard Box, Leather. There were only 3 available in the dealer group. I lucked out and got the only CC Standard Box in the dealer group inventory at the time.

Here is my "Executive Garbage Hauler" as my boss calls it.

I think that TSB is only for 15 and 16 model years. I wasn't able to find anything matching for 17 model years. That being said, I did notice that the loaner 2017 6.2 8 speed I had for a short time had a defined kick when downshifting to gear 1. My new 2017 5.3 8 speed is smooth like butter.....although I only have 900 miles on it, time will tell.

I traded in my 2015 GMC Canyon for this new 2017 SLT All Terrain. I needed something with a 6'6" box. It was hard to find, as most people in the city want their short boxes.
