    How reliable is the new GMC Yukon Denali CL, especially with the new LZ0 diesel engine?

    You asked about "long term reliability", but this is still only a 3 year old platform. I think that you are going to find more negative feedback in an online forum than reality. People don't share good experiences nearly as much as they do bad ones. My '22 Duramax has been flawless with the...

    How can you afford the cost of a new SUV?

    I definitely understand the economies of scale and lack of investment, but I don't believe for a minute that you can get all the parts made, to a single location, and assembled for 500 - 750. Tires, Body Panels, Engine, transmission, differential, glass, paint, interior components... Oh, and...

    Cany you clarify the $500 - $750 per vehicle cost. What does that number include? I am struggling with that one...

    21+ IRS SAG issues when towing product design (looking for someone in Michigan)

    I thought that the "new" independent rear suspension on this generation of Tahoe / Yukon prevented these options. I am very interested in stiffening up my rear suspension to avoid towing sag if possible. Do you have any specific information, i.e. a link to a product, that can be added to these...

    Important Update!

    I am not saying that you are wrong, but a couple of updates ago it failed on me 3 times in a row. I connected to Wi-Fi for the 4th attempt and it worked. Maybe it needs communication to validate or something?

    Important Update!

    To prevent the failed updates, I have decided to only do updates at my house where I can connect the vehicle to my home wifi before installing. This method has been succesfull so far.

    Intermittent A/C

    This wont help you, but I had a similar problem in my 1987 Balzer in the late 90's. The clutch on the compressor would stick and not kick on. The solution was to find some bumps on the road or the shift into neutral and rev the engine. The vibrations from either solved the problem 95% of the...

    OTA Update GM N22-238206 HVAC Quirk

    Took it back in yesterday and they now find a bunch of codes stored. I didn't get a copy of them, but all connection issues with the radio. will leave it with them next week to try to address. This kind of works for me. The fan speeds up, but them I get a voice telling me that I need a...

    If you had a do-over, Would you buy your duramax all over again?

    I am by no means high mileage yet, but I am on about a 30k / year pace. 36k miles in about 14 months. Not issues, knock on wood, other than software. I do regular oil changes per the schedule, fuel at 2x the recommended rate, and will likely do transmission fluid early (50k) too.

    Pump DEF or bad idea?

    Yeah, but then you have to go to Walmart... Truckstops are nicer and safer than Walmarts where I live!

    Pump DEF or bad idea?

    I have only used "pump DEF" for the last 20k miles. No problems. Easier and cheaper.

    OTA Update GM N22-238206 HVAC Quirk

    Following up on this... I left mine with the dealer for 2+ days. Complaints were Google Speech error message popping up, HVAC fan slowing, and radio cutting out a couple of times within the first several minutes of a drive. The tech notes were: "Radio Software Update Y167 Available to correct...

    Dealer oil change $$$

    $110 each for the "diesel" if you buy 3 at a time at my dealership as of this AM, but it didn't have any distinction between the 3.0L and the bigger diesels.

    OTA Update GM N22-238206 HVAC Quirk

    Does anyone know how this type of thing will be handled out of warranty? I am at about 35k miles and reported the issue to the dealership, I plan to leave it with them next week, but if there is no fix and I run past 36k am I then on my own? I am certainly not anti tech, but this tech seems to...
