Hello, I searched but couldn't find anything. I am looking for advice on resolving my CEL P0449 on my 19 suburban 5.3 with 110k miles.  I replaced Vapor canister vent valve solenoid and Canister Purge Valve. I cleared the code and it came back.  I am thinking my next step is to trace the wiring but before i did that id like to see if there is a common issue i am not aware of. Any suggestion on what i should look at next?   Thank You     ..read more

Truck is a 2020 Yukon XL Denali.  This is a used but new-to-me truck.     I confirmed in the settings that the handsfree is selected "on"   As title says, my handsfree liftgate is not working and I'm looking for guidance as to where to start troubleshooting the issue.  I crawled under the bumper this morning but could not visually identify a sensor.  Where should I start looking to chase down the issue?     It should be noted that when I picked up the truck, it was missing the tow-hitch cover and the very bottom of the bumper, directly bel ..read more

2015 Yukon Denali. On my other vehicles the adaptive cruise control is a very nice feature, but on this truck it is terrible.  Even at the farthest setting, it keeps creeping up on the car in front until it's dangerously close.  I'm talking 10 to 20 feet away from the car in front, even at highway speeds.  Also, it seems to accelerate above the set speed to keep up with the car in front.  I'll be cruising along at 75, set at 75, and as soon as a car pulls in front of me it abruptly accelerates to 77 as soon as it recognizes the car. I find this very strange.   In my pr ..read more

I just completed a 6-inch suspension lift on a 2019 Suburban Premier 4x4.  The Adaptive Cruise control keeps stating "Temporarily Unavailable".  What do I need to do?  Recalibrate the radar box behind front bumper?  Relocate the radar box?  Is there any way to bypass the radar system and have standard cruise control???   Thank you for your help ..read more

So I bought a one owner 2015 gmc yukon denali and right away noticed a terrible noise on the drivers side when you go over any sort of bump or hill. It is much worse when you sit in the middle bench seat. After 6 months of my dealership trying to figure it out ( replacing all shocks and much more) I decided I was done and traded it in on a 2016 yukon denali xl. I have now owned the car for 3 weeks. The first couple days I didn't hear anything. So excited! But then I pullout to the side of the road and boom I head it! It was minor so I ignored it. But not it is all the time just like with my 20 ..read more

I know it sounds completely rediculous but I have a rattle that drives me crazy. It's been there ever since we purchased it and I've moved things around (rear middle seatbelt, latches on the wall in the 3rd row, so forth.) anyone else have this or can give me any ideas where to look next? I am waiting to get my rear spoiler replaced due to it popping and not opening. So I guess I can have them laugh at me when I bring it back to have the spoiler installed and make them track the rattle down ..read more

What exactly does the "On With Towbar Attached" setting change about the park assist?  I have not noticed any change.  When having my rear mounted cargo basket attached, the park assist system will automatically disable itself after sensing such a close proximity that doesn't move after a certain period of time, regardless of the infotainment system setting.  I really wish the rear park assist could be disabled separately from the front sensors but that's a pointless conversation given how little I use a cargo basket out of a full year of driving.  From my research the owne ..read more
