    Odd misfire at idle on 5.3

    I’ve had that a few times too. It’s more than the usual shudder at idle and is an obvious misfire for a half a second or so. No lights illuminate or anything when it happens. I’m not sure if it’s a fluke or the quality of the gas (I usually do put in 87 octane w/10% Ethanol that’s Top Tier...

    Onstar vs Cell Phone Pairing

    I thought I saw there was a plan for $11 which allows for the in-dash and apps to work but I’m having trouble locating that now. Also remember if you buy a brand new one OnStar is baked into the cost of the vehicle for the first year or so. On my 2021 with the older system, my phones...

    Blacked Out Infotainment Screen Recall (Software Update) / Left Turn Signal Noise Briefly Disappears Occasionally

    Interesting. There is supposedly a new infotainment software version out (I think it's V160). I'm going to pressure my dealer to try installing that update as this problem for me started right after they installed that blanking screen update. Last time I complained about it they could...

    Ota update!!!

    What year is yours? I’ll have to check on my 21 Tahoe. If it’s a 21, hopefully it’s the V160 software version for the infotainment system. I’m hoping that fixes my turn signal noise disappearing while it’s flashing occasionally.

    2021 Denali OTA updates

    As of August 2022 there’s supposedly a new software update out that addresses multiple issues according to the TSB 22-NA-127. I’m not sure exactly what it addresses..curious if anyone is able to find that TSB description.

    Wheel alignment question

    Unfortunately mine has been a little odd since day one. I had the dealer perform an alignment on it to hopefully fix it being off a little to the left all the time and it did nothing for it. I’d be happy if straight on the steering wheel meant straight down the road. :)

    Front Bumper near Front Headlight

    That’s exactly how my 21 looked prior to them repainting it. Today though it’s still as bad as what the photos I posted. Really curious how long it will be before it chips off again. Curious what fix they do on yours and hopefully it’s better than what was done on mine.

    Real Life MPG 5.3 / 6.2

    Here’s the best I’ve been able to achieve in over a year on 87 octane with 10% ethanol (if it has didn’t have ethanol then it would’ve been higher). What’s interesting is on the other screen not shown after filling up it thought the max mileage is 520 miles. Some of this driving is a mix of...

    Anyone found Velcro that works for rear cargo all weather mats?

    The last section in my mind is the part that would sit behind the 3rd row seat. The others hold in place fine in mine, but that last part leading up to the rear gate doesn’t stick at all.

    Anyone found Velcro that works for rear cargo all weather mats?

    Lol…I agree that it sucks bad. I tried using some carpet tape to keep that last section stuck down but it didn’t help any. I’m not sure what to do but I am overly annoyed just like you with it. If it wasn’t for that one last section, overall the all weather floor mats and the other...

    Driving in L9 and DFM

    I have my doubts driving in L9 would be the perfect solution as when in Park the DFM will probably kick in while idling...if that's the case, then the issue is still going to crop up. That's just my take on it. I've had one side replaced at 9,100...currently at 11,500 and a little leery as...

    Premature tire wear

    Thanks for the info...Will keep that in mind for when I'm ready.

    Premature tire wear

    I can tell you that I'm not impressed with my tires on my '21 Tahoe which has 11k miles on it. It's got the 22" wheels. I was looking at the tread wear the other day and had the dealer perform an alignment at about 800 miles. Seems like they're wearing more on the outside edges than the...

    Front Bumper near Front Headlight

    Anyone else have an issue in their 2021 model with the fit and finish of the front bumper piece where it meets up with the fender and front headlight? Attached are photos if what mines doing. I had the dealership fix this once where they removed the bumper and repainted it as there was a...

    Fog/Driving Light Install 2022 Tahoe

    I think it's stupid the 2021 Tahoe Premier doesn't have fog lights. Would love to add them onto mine. I'm not even sure if the wiring exists for them. Curious if anyone chimes in.

    Add Failed Rocker Arm to the list...2022 Tahoe 6.2L under 6k miles!

    It drove fine for me to work that morning then when I started it up to drive to another location after it sat for a few hours I could tell right away it was missing. It was running very rough and after I started driving it down the road I got multiple warning messages about traction control and...

    Digital Review Mirror Green Hue

    I've noticed that a few times when first starting it up, but it goes away for me after a second or two. If it stays that way might want to take it in as maybe there's an issue with the LCD panel on the mirror.

    Order pulled?

    Wonder if this is a factor for it being pulled. Sounds like for the pickups the 6.2L is unavailable to order along with the diesel due to supply issues. Guessing it will be the same for the SUVs soon...

    Poll on lifters

    I had the same issue...mine was built March 2021 and had one failed lifter about a year later in April 2022 at 9,100 miles.

    Add Failed Rocker Arm to the list...2022 Tahoe 6.2L under 6k miles!

    I tried the same thing when I got half the lifters replaced last month. Supposedly they’re giving me two years of free oil changes and 20k in GM points, but I have yet to see either of those show up in my GM account. I’m not satisfied either with that…I feel extended powertrain warranty would...

    Can the rear unlock/locks be disabled.

    I’d like to be able to turn off or disable the switch. My kids play with the switch driving down the road. My old 2017 GMC Acadia had a disable button that worked great but I don’t think it exists on my 21 Tahoe.

    Real Life MPG 5.3 / 6.2

    Just curious…do most here leave the auto start/stop enabled or disabled? I had disabled it each time I started it for the past year, but now that I had the lifter issue and only half were replaced I’ve been leaving the auto-stop enabled. One side effect of doing that is I am seeing better...

    2021 Denali OTA updates

    Course right after I posted the last post, my wife’s 2020 Traverse which has the same Infotainment 3 system just received an OTA update today. Maybe there’s hope we still see some updates on our large SUVs.

    2021 Denali OTA updates

    I thought someone else on one of the other posts stated that GM stopped doing OTA updates on the 21’s due to some issues they ran into with it. I know with my ‘21 Tahoe, I haven’t seen any updates since something for the airbag. I’d like an update to fix some weird turn signal noise issue...
