    P1098 CEL

    This is the truth and ultimately the case for me as well. I ended up taking mine to the dealer and had the valve replaced under powertrain warranty. My dealer gave no stink about it. But I’ve heard others saying their dealer did not want to cover under powertrain, which is a load. If this ends...

    P1098 CEL

    Hello all! Just curious if any of you have experience with the P1098 code? I’ve only found limited information here on the forum, however I did seem to find additional info on other various websites regarding the code. Yesterday night, after start up, the CEL illuminated. Called onstar and they...

    DEF level sensor issue

    I’ve experienced odd things with my DEF gauge as well. Someone once said that it’s not a normal sensor and it uses more of a “guesstimate” by calculating the range or something? Anyhow, usually I only experience “issues” when I am towing. Same as you, gauge will show half tank, then suddenly...

    3.0L Duramax Towing?

    This was exactly our experience. On longer trips we now bring a few boxes of DEF just in case!

    2023 Tahoe LT Duramax (w/ Luxury Package) - Initial thoughts after 3k miles

    I’m fairly certain you can modify the settings to have the seat rumble when veering out of lane. I have a 21’ Yukon that vibrates the left/right side of the seat depending on which line I’m hitting. I recall changing that within the vehicle settings somewhere?

    3.0L Duramax Towing?

    I haven’t personally experienced oil consumption. Honestly I haven’t checked? But after 34k miles and maybe 5-6(?) oil changes, no one has expressed concern with the oil level. Not sure if this is normal? However now I’m curious to check though

    3.0L Duramax Towing?

    Nice! Yeah we blow through the DEF when we tow. Learned the hard way when the system suddenly told me I was critically low in the middle of no where LOL luckily we found a gas station that carried it fairly quickly.

    Duramax odors in cabin

    I have a 21’ 3.0l. I pretty much only smell it when it’s going through a regen and sitting at a stoplight or similar.. however I have notice when it’s cold out (below freezing or close) the smell is worse. I do smell it in the cabin.. and have been told by the dealer it’s normal. However after...

    RV Towing

    I have a ‘21 with the 3.0l and tow package. We pull a 24ft (28ft including tongue) weighing maybe 7k loaded. It pulls well but the wind kinda pulls you around. Biggest concern is the tongue weight. Wouldn’t be able to do it without a weight distributing hitch! Have to take it slow up hills.

    Towing 18' aluminum car trailer with diesel 3.0 23 Yukon

    I pull a 28ft travel trailer with my 3.0l Yukon. Weighs probably close to 7,000 loaded I’m sure. You can definitely tell it’s back there but it pulls well. My biggest concern is the wind pulling me around. I’m also patient when climbing hills.

    Yukon Diesel + Maximum Tow Package - Anyone??

    I have a ‘21 SLT with both the tow package and the diesel. I think I got lucky as I caught it on transport in may of 2021. Restrictions came soon after

    Integrated Brake Controller/Gain issue?

    Hey all! I am fairly new to towing, especially with my 21 Yukon with the duramax. We bought our trailer earlier this season. This last trip we took the trailer on, we ran into a strange issue with the trailer brakes. Normally we keep the gain set to about 5. However, coming off an exit on the...

    3.0L Duramax D.E.F. Gauge Issues?

    Hmm. That’s interesting to hear! Thank you for sharing. I’m keeping my eye on it for sure. Sort of waiting to see what happens this next time I get low on DEF fluid since I’ve just filled up. Hopefully it was a one time thing but we shall see!

    3.0L Duramax D.E.F. Gauge Issues?

    Interesting to hear. The math still doesn’t add up but I figured it would consume more when towing. I did consistently check after I filled it to see how much it would move the rest of the trip but the gauge never budged for another 200 miles.

    3.0L Duramax D.E.F. Gauge Issues?

    Recently while towing I had roughly 1/4 of DEF fluid left per the dash gauge. While we were towing, the message popped up letting me know I had roughly 270 miles left before empty on the DEF.. roughly 10-20 miles later another indicated came and told me I was critically low and it will start...
