My AT4 felt the exact same Felt like rear wheels were coming off the ground/which made towing scary at higher speeds. Put on some of the bilst 5100 shocks and so much better. seems stiffer over smaller bumps but i can tell it is stable on the ground. The rancho shocks are pure garbage, the rebound rates are all wrong-soft ride but no stability.

Yes I have had this problem Still do. 2 diff trailers both work perfect on a 2008 gmc, 2015 chevy and a 2018 gmc no bulbs out. plug them into my 2019 gmc and no trailer running lights. tells me bulb out. brake and turn signals work perfect. dealer can not find answers. Hook up to brand new trailers and it works perfect. If I disconnect one side or the other side lights it works perfect. I'm guessing the allowable range they programed the computer for is too narrow for older conventional trailers. Tried replacing plugs and lights with all new, no luck. This spring I will run a separate ground wire to each light instead of allowing chassis ground for the lights. Maybe the resistance is just to high on an old trailer.

My opinion, if the light comes on drive it till it seizes Guaranteed a new motor. Sorry there was no where safe to pull off and stop mr gm.

I have not heard the camaro or vette do it either. However this is the first 6.2 with the DFM Where it can go from 8 cyl all the way down to 2 cylinders during deactivation. While that does seem very smooth compared to the old AFM v8/v4 mode it is a completely new setup. I'm guessing they either have a design flaw that needs to be corrected or a supplier severely screwed up. Teach me to buy the first year Just really disappointing

Mine just started doing the exact same thing!! Defiantly not "normal" even though the latest bulletin claims to let run 5-7 minutes and if goes away give back to customer and tell them its normal. Research department is investigating the cause. Really? Normal? How ever if it continues past 20 minutes go ahead and replace the lifters. Been a technician for 35 years This sound is anything but normal. GM I hope you are watching/reading poor quality period You know why it is happening, you just don't want to cover/handle it. Can't wait to hear what load of bs my dealer tries to tell me. AsBIGDOGx stated let it blow up and make them warranty an engine.
