    Extended crank but no start issue

    Maybe. 54k miles now. Still liking it.

    Extended crank but no start issue

    I think the reflash helped… for the most part. For my truck, it will not start on the second or third try. I have to disconnect and reconnect the battery for whatever to clear so the truck will start. I have a 10mm socket in the glovebox just in case.

    Extended crank but no start issue

    Im guessing this is a computer thing. When it was trying to start it said low battery in the info screen. It mentioned something about going into battery saver mode. Thats a new one. I unplugged the negative for a minute, reconnected and the truck fired right up. It did ask me to roll the...

    Extended crank but no start issue

    So….. I had the reflash done a while back and just had the extended crank, no start…. Again… tried twice in a row, no go. I unplugged negative battery lead for a minute. Tried again and it fired right up…

    DEF can I drain the tank?

    The urea should go back in to solution I would guess. unless the def tank is an open system and water is evaporating to cause urea to crystallize out. I hope that wouldnt be the case.

    DEF can I drain the tank?

    Calcification sounds like they are not using distilled water. IMO

    Cost of Fuel Filter a little Shocking

    Went to my dealer to pick up a fuel filter today. $77.78. Ah… $28 bucks plus shipping at Rock Auto. Wow. I think the last fuel filter was like $40 at the dealer. Doubled in price from December 2021. Dang inflation.

    Exhaust/Engine Brake, or lack of

    I think that is just hill descent control. My 2021 has the same button.

    Exhaust/Engine Brake, or lack of

    How powerful of an exhaust brake should be expected for a 3.0L engine? I’m guessing it should be noticeable but nothing like a 6.6L duramax.

    Excessive oil consumption?

    Wow. I wish GM would have spent more time with this engine before updating it. Keep us posted on what GM has to say about it if you take it in.

    Extended crank but no start issue

    Didn’t happen to me until 25k. It did it 3 times before I had the reflash.

    Extended crank but no start issue

    Hopefully the reflash works for you. It worked for my truck. The engine turns over noticeably longer than before. That’s about it.

    Excessive oil consumption?

    Interesting. Another interesting thing I’ve learned… No magnet on the oil drain plug…

    Three weeks in the shop and waiting...

    They all have their problems. The new tundra and waste gate solenoid. Ram and that gawd aweful 8 speed trans not to mention the eco diesel. I also had a ‘14 Silverado with 5.3. After 70k. I burned a quart of oil every 5k. I had computer issues that locked the steering wheel in place while I was...

    BREAKING: New LZ0 Duramax Engine for 2023 GM Trucks

    Maybe the LZ0 is the version that is so efficient it doesn’t need DEF…. Glad they can design a new engine but struggle to optimize their DEF system from tank to “indicator.” Just poking… I am still happy with my LM2.

    Three weeks in the shop and waiting...

    Sorry to hear some people have had so many issues with their trucks. Best of luck with the ZR2. 6.2 should be a good engine. After this LM2, I don’t plan on ever owning a gas fed truck again. Time will tell. 31k miles I’m still happy.

    Extended crank but no start issue

    I had a 2015 Ram Hemi. Went through 3 transmissions. Heaviest towing was 4500lb snowmobile trailer maybe 2000 miles/year. Had both exhaust manifolds replaced, one head, and a pressure sensor in the fuel tank. All in 104k miles.

    DEF, Platinum DEF?

    Couple of YouTube videos and articles about Platinum DEF causing trucks to throw codes. There is another video that discusses a stabilizer in platinum DEF. Not sure what that stabilizer is and what it does to stabilize urea in water.
