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.

my truck has had a cold start knock since new. Its now at the dealer for a misfire

I’m having very faint misfires under light acceleration when the engine is cold.

Have you gotten any resolution?

This could be dfm related.

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.

Ahh.. man don't make me loose sleep over this haha.

Really bummed about this guy's trailboss .. so far just the basic recalls for me

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.

update on my 2019 trail boss after 9 months of problems with no fix i took a loss and traded the truck in now i have a 2020 trail boss with no issues ... GM was no help and the only reason i got an other Chevy is cause the dealer knew there where issues with the truck but still gave me trade in value on truck in good condition ......

Keep us posted, I am considering trading my 2015 LTZ for a 2020 LTZ in the next week.

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.
