    Benefits of the diesel?

    We have 3.0's well into the 100,00's, never had one go bad, never replaced one, but I am sure there are a few out there that failed. DPF's can be cleaned, which is done on Class 8 trucks at 500,000, I haven't seen any GM documentation on when, or if it needs to be removed and sent out for...

    What DEF Fluid?

    Truck stop DEF from the pump. The stuff has a shelf life. Rule of thumb I operate on, never let it go below 1/2 a tank. My mechanic told me years ago to always stay above a 1/2, if you get bad DEF, it will be diluted enough with the good that is there and you should be ok, and worse case you...

    The Most Reliable Duramax Diesel Engines ...

    When I read the LB7 was one of the most reliable, the author is talking out his backside. The LB7 from the factory had injector issues, even the updated injectors are junk. The LLY I would buy before the LB7. Some of the LLY's had an overheating issue, but I never saw one, but over a Diesel...

    Which center console do you prefer?

    We use our sliding console frequently. We usually slide it back when we have our kids, or grandkids sitting in the back seats, it moves the cupholders closer to them. I have a safe for ours, unless I remove the holster for mine, it doesn't fit in the lower drawer, it does in the console safe. I...

    How much trust do you have in the 3.0?

    This video has been discussed on most of the diesel engine forums. Most of the comments from the gearheads are there isn't any engine history, maintenance records, and they all commented that GM won't warranty the failure. Most of them suspect it was chipped, which GM can see in the ECM, there...

    Problems with emissions systems?

    I have had just about every GM Diesel starting with the 6.5, through the latest designs (Isuzu and Opal based). The 8 Cylinder engines were an Isuzu design. The only one I have had issues with was an LB7 (2003 MY), injectors. I had an LBZ (2007 MY) that I gave to my son, it now has 375k on the...

    Radio and Turn Signal Audio Anomoly

    The lane lines stopped working as well, the updates at least I have green lane lines, but they don't turn yellow anymore, nor do they disappear when there are no lane lines, they are green all the time. It went in this morning, there are no codes, everything passes diagnostics, but they test...

    Radio and Turn Signal Audio Anomoly

    First thing I checked, it is enabled, also noticed it doesn't try and gently nudge the steering wheel either. I always like when updates don't work as they should, or break something else. I could understand the lack of testing prior to release if there were variables GM didn't control that are...

    Lane assistant really bad

    I have a 23 Yukon and a 23 2500HD, both are the same trim levels. The lane departure is like night and day between them. The Sierra's is more what I would expect, when you get close you get the warning and it tries to correct what you are not doing. The Yukon, the lane departure on it and Super...

    Radio and Turn Signal Audio Anomoly

    Today was the day, a new update was done. Hopefully this is the fix. I rarely drive it, the wife does 95% of the time. I get in it, went to lunch, and I noticed the Lane Keep Assist was displaying, the seat wasn't vibrating, nor were there any beeps. Called the wife, she hadn't noticed it, so no...

    Question on the anti crash technology

    I know because if I don't have my foot on the accelerator and the red collision starts flashing, it applies the brakes. If you keep your foot on the accelerator, the flashing red crash comes up, but it doesn't brake. This was in an email the dealer sent me when I asked about it...

    Question on the anti crash technology

    I can override mine by accelerating, the red flashing you are going to crash still occurs, but if you keep your foot on the gas it won't apply the brakes.

    GDE tune for LM2

    I know for fact GM will check the ECM for changes done to it, GM somehow can tell it was changed (GM says there is a fingerprint written evrytime the ECM is updated, or restored), as well as non-GM approved exhausts (Cat back is ok, cat or before is not). GM started checking around the LLY and...

    VSE Fuel Saver System for 3.0L Duramax

    I have owned a number of diesels, the LM2 uses the same filter as the LP5. On our business side, we don't add any filtration, and we have yet to see any fuel issues in any of the GM, RAM, or Ford diesels we have. My son has my old LBZ Duramax, over 350k on the clock using the stock filters. The...

    If you didnt have a Yukon/Suburban/Escalade, what would be your next choice?

    Lexus LX600, the 2022 Expedition one of our sales folks drives, as well as everyone I know who has an Expedition, all have had their transmissions replaced at once, one of them is on their 3rd tranny. I realize they all have issues, but transmissions seem to be the weak spot.

    Bridgestone tires. good or bad? My experience.

    Our Yukon has 18,000 on it, plenty of tread remaining, they are 275-50-22. Most of the miles are highway speeds, 75-80, no flats, no abnormal wear, no balance issues, so far problem free.

    Might want to take a look at this thread. I doubt there is much difference between the year models. https://www.tahoeyukonforum.com/threads/dual-battery-setup-using-oem-parts.131917/

    2023 Yukon XL Denali consol safe

    It isn't deep like my 2500, but a S&W M&P, and Sig 365 fit in mine.

    Yukon 2022 instrument cluster stopped working and lights are flickering.

    I think there is a TSB for that.

    Waze on the main screen

    I installed it, then removed it. The only way the screen would show where I was in real time is if I had Waze open on my phone. I still use Waze, just launch it on my phone when I need it.

    Radio and Turn Signal Audio Anomoly

    The Y171 update was applied already, but my mechanic said there is yet another TSB for the issue GM is still working on trying to resolve. https://static.nhtsa.gov/odi/tsbs/2024/MC-10249982-9999.pdf

    Radio and Turn Signal Audio Anomoly

    Last night I am driving, go to make a left hand turn, used the turn signal, heard it through the drivers side speaker. About 10 seconds later the audio for everything, including the turn signal muted for about 5-6 seconds, then unmuted and worked fine. Around 30 minutes later, staring at a red...

    Beware: GM Nightmare - Defective 2024 and 2022 Yukon Diesel

    If your thought is GM is the only one with quality issues on some of their builds, you will be in for a rude awakening. Owning a business, we have a mix and match fleet, we used to be all GM until the vehicle shortage hit, then it was buy what we could find. The overall majority have minor, or...
