Looks like I'll be the first to go to the dealer next week. Out of like 5 trucks of people we know, they're all leaking around that inspection cover.

Just crawled under and saw this..... My buddies 2020 is doing the same thing. 17k miles

I wish gmc would up the psi to 110 for G rated tires though Sent from my SM-G973U using Tapatalk

Had a 2017 Suburban that did this. First. Vehicle ever that could not block outside air with recirculate on. Just traded it in for a 2020 gmc sierra. Recirculate works like its supposed to and I can not smell any outside air any more. Such a Shit idea by GMC to not block completely. Inhaling exhaust fumes in tunnels and other areas is terrible.!

I'm thinking about rigging up a piece of sound proof material and gluing it around steering column and hole on the inside. Hell, I may even just duct tape it. Sent from my SM-G950U using Tapatalk

I heard a little ticking again the other night. I wonder if the grease they packed my new boot with is leaking out...... Sent from my SM-G950U using Tapatalk

Sometimes my recirculate is 100% and sometimes it's not it seems. I don't know. Carob air filter helps. Sent from my SM-G950U using Tapatalk

Truck is dead silent after pip5570 fix all. No ticks at all and drove 10 hours yesterday. Go get it done for sure! My dealer applied grease too, so not sure if it helps or boot is enough. Sent from my SM-G950U using Tapatalk

Got my truck back after I showed them the pip5570A Tsb. No ticking thus far and took some pics of the new boot. Looks like they put some grease in there too. Will report back in a week. Sent from my SM-G950U using Tapatalk

Dropped mine off Monday and showed them pip5570a. They're applying a new boot. I showed them the grease trick and explained how it was working and all makes sense. I just forwarded them the previous message about something behind the dash also rattling possibly. I'll let you all know when I get it back. Sent from my SM-G950U using Tapatalk

Please let us know if the new boot fixes it. More validation would be helpful before I drop my truck off again for the 5th time. Lol Sent from my SM-G950U using Tapatalk

I left my service manager a voicemail about it and asked him to call GM about it. Sent from my SM-G950U using Tapatalk

Welp, sprayed white lithium grease around boot and..... it friggen works. Not one tick..... I was thinking about taking a piece of high heat sound proofing material and wrapping it around part of the steering column. Should absorb any reverbaration up the column. What do you guys think?

Thank you both. I will report back my findings as well. Ticking was loud as hell on last road trip I took. Tick tick tick all the way down the highway on cruise. Sent from my SM-G950U using Tapatalk

Can you snap a few pics of the locations? Sent from my SM-G950U using Tapatalk
