Jeez, I am reconsidering picking up one of these new models if they are going to be having these issues right off the bat.  Not what should be happening when you spend $40k+ on a vehicle, plain and si

My 16 was in the shop over 30 times, and that was after three years of the manufacturer working out bugs. It's a roll of the dice. Sent from my Pixel 2 using Tapatalk

Some dealers can not give a crap about getting something fixed. If it's not something they know about they won't waste their time actually diagnosing an issue and trying to find a solution. There's a

I was hunting in the cold and snow in Utah. I tried to back up on a hill put in reverse tires spun loud pop and grind and loud spinning noise. All 4 wheel drive lights went off had no 4 wheel drive. put in drive, loud pop grinding noise loud spinning noise, and transmission  would no longer engage. Slid down hill over small embankment stuck. transmission  would not engage no 4 wheel drive lights  Error message included service transmission, transmission Service   ESC reduced engine power, brakes, trailer. and others. A hunter offered to pull me out put in neutral. After pulling me about a bit transmission came back. I drove it a bit 4 wheel drive came back. I turned it off and back on all Error messages were gone and truck ran fine. I took to the shop and there are no codes in the history so dealership and Chevy will not look for anything that caused the problem.  They say sorry no codes no help. IS there no history on the computers also can someone tell me what to tell the dealership that could tell Chevy what could have caused the problems. I am scared to death now to take it back into the mountains.

Nah, it’s mainly noticed taking off in 1st and 2nd gear under light load. I think it’s a bad temp sensor or something but I’d think it would throw a code.

Has anyone had an issue with what smells like mold? Like a musty smell? U can like taste it on your tongue. I bought a brand new 2019 trailboss at the end of September. Since then I have been to the dealer 4 times about it. Doesn't even smell like a new car and it basically makes me have an allergic reaction like one would have to pollen etc. I Dont have any allergy's so its pretty weird. I filed a complaint with GM and we are on month #3 and no solution. I have been pushing for them to test the seats but they haven't. Its cloth interior. Obviously when i first brought it back the guy who sold it to me said it was the new car smell. he is also the one that told me to file the complaint with GM the 2nd week of having the truck. Anyone else experiencing this smell? I was so jacked up when I got it I didnt even realize the smell.

I bet you have the rear window water leak.  Might check that out in the post titled for it.

My new 2020 TB got hydrolocked driving in rain on a very wet road.  Design flaw for sure.  They wouldnt even cover with warranty because they said it was my fault!!

It's a TRAIL BOSS 4X4 and I was on a mountain road in the rain!  WTF.   I hear this is an issue with a lot of the 2020 vehicles.  I just got a lawyer.

 

dont buy this truck

Andy, I work for GM on the sales side. This is par for the course.

 

I also have a 17 ltz midnight crew cab and a 20 custom trail boss

 

The trail boss I picked up yesterday, so far so good. 

 

The LTZ, inside of 35k miles has needed, tires, a battery, multiple adjustments to the leaf spring "area" because of a clunking and lots of gas (6.2). I also cut a turn too tight and hit someones f350 on the wheel well - ouch.... anyway

 

I drive on the beach alot to go fishing here on Long Island, and I air down normally to 20 or 18 unless its really sugar sand hot summer situation.

 

Last summer dead of night im rolling along and the truck starts spitting codes like you said above. I lose 4wd - luckily the locking rear diff and the aired down tires allow me to cruise for a bit to find a firm spot to stop - Almost every light was on but I was rolling - found a flat spot to stop on. I adjusted the gauge cluster to show me the 4wd screen and it showed I was in 4wd - so I tapped the gas a little and I was back in 4.

 

Got off the beach - it wouldnt come out of 4wd. SO I turned down the closest block after beach exit and fiddled with the rotating dial - service 4wd - . I shut the truck off and started and all seemed normal. Guys at my shop couldnt see anything.

 

Battery died on me at 30k miles for no apparent reason. Stuck me with my infant at home depot.

      Exhaust Question

      By C. Hart · Posted

      I have seen different people in different places post different sizes of exhaust as stock for my 2014 Sierra L83. Some say 2.5 some say 2.75. I am considering replacing the muffler with a Dynomax Super Turbo, perhaps 17739.  I had the factory L83 5.3 replaced with another L83 5.3 from Jasper Engines. I also put new Walker Cat / Y pipe on. I would appreciate opinions suggestions about what would be a good muffler setup. My main interest is a low rumble and the best flow / fuel mileage I can get. Not interested in straight through glass packs or loud exhaust. Those days are way behind me now.  Thanks Guys.

      Cold start Miss, oil in cylinder

      By newdude · Posted

      Its coolant disguised as oil.   TSB 20-NA-166 -  20-NA-166 1..3   "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix"     I'd say its the head, and its either leaking at the casting line and dripping down the intake into the cylinder, or its another spot on the casting itself at the cylinder that is getting wet.

      Cold start Miss, oil in cylinder

      By asilverblazer · Posted

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      Navigating senior years.

      By garagerog · Posted

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
