    CarPlay audio cutting out (revisited)

    My audio cut out is becoming more frequent. Either way, I think I’m gonna have to have the dealer fix it, but I’d like to know what the issue is, and perhaps if there is an easy fix. Again, it’s all audio regardless of the source

    CarPlay audio cutting out (revisited)

    Came to see if anyone else is having the same audio cutout that I’m having in my 2021 Yukon SLT. Seems I’m not alone. For me, it’s all audio: CarPlay, terrestrial radio, satellite radio, ph calls, even the turn signal audio clicks go silent. There doesn’t appear to be a rhyme or reason to when...

    2022 Yukon XL Camper Towing

    Out of curiosity, what's the concern with sag? I recently towed a car with a '21 Yukon, 5.3L, and max trailering package. It looks like quite a big of sag (couldn't move car back on the trailer) but the Yukon pulled beautifully, without steering or stability issues. Total weight: 6000 for Yukon...

    Whining sound just started (after towing a car)

    Update: I took it to the dealer and they said the whining was the idler pulley and will be replaced under CPO powertrain warranty. They said the AC issue is a leaky rear evaporator and quoted around $1500-$1800 to replace. I called my indy mechanic and he quoted something similar. I think i'm...

    Whining sound just started (after towing a car)

    I’ve also seen people posting about a blending door not working properly. I’ll need to find out how to add refrigerant and then get someone to find the leak.

    Good call. I have no idea how to do that but I’m sure YouTube can tell me!

    Whining sound just started (after towing a car)

    Update: It sounds like the whine is coming from the engine bay. I couldn't pinpoint exactly where but as someone else revved the engine a bit, the whine definitely sounded like the motor. So, i suspect one of the pulleys or ancillary parts. I'll try to upload a video later. I am also having an...

    Whining sound just started (after towing a car)

    6000 for Yukon, 2200 for trailer, 3800 for car, 605 passengers and dogs, 100 luggage, 215 lbs fuel (both vehicles, full tanks)=12,920. I'm sure there are odds and ends I left out but I think i was safely under.

    Whining sound just started (after towing a car)

    Thank you for all of the replies! I'll get under the car tonight and look for leaks. I think it could be the transmission pump gear but will investigate further. Luckily, if it's a drivetrain issue, it'll be covered under the CPO warranty. F this thing. I'm dumping it before I lose the CPO...

    Whining sound just started (after towing a car)

    This past weekend, I used my 2021 Yukon with the 5.3L motor and Max Trailering package to tow my convertible to the Sandhills Open Road Challenge. I had three adults, two kids, two small dogs, and luggage in the Yukon and the car on a Uhaul car trailer. I'm strongly leaning towards a diesel...

    2021 Tahoe A/C blowing warm on driver side.

    Having this same issue in my 2021 Yukon. I have a few questions: 1. Doubeleive said "stick a camera up there and check it out, manually moving the door should make it work 100%" Where do I stick the camera? And how do I manually move the door? 2. DanJanson said that adding refrigerant helped. I...

    Emergency: Reverse button broken, won’t shift into reverse

    Third update: new buttons were installed and I picked up the Yukon today. The repair was covered CPO warranty. So, not great but lesson learned. If your button breaks, press the white tab!

    Emergency: Reverse button broken, won’t shift into reverse

    Ha! That's thinking positively! Also, my loaner on short notice is a 2024 "Turbomax" Sierra. I'm sure it'll do massive burnouts if given the opportunity.

    Emergency: Reverse button broken, won’t shift into reverse

    Second update: we were able to engage Drive by pressing down on the white plastic part in the button that appears to connect to the light. It also worked for Reverse so if you find yourself with broken shift buttons, press down on the white plastic “tab” to the left of the light.

    Emergency: Reverse button broken, won’t shift into reverse

    Update: the car in front left so I headed to the dealership. Stopped to get gas (needle pegged on E). Went to leave and whaddya know, the Drive button broke. The gas station is across the street so I walked to the dealership to figure out how to get it over here.
