Can you add more about the tick... Is it a random, does it sound like it has rhythm to it? Is it loud like a hammer tapping on iron, or something else. DI engines tick like crazy!

I guess this is either a known issue or I'm the only one that notices this sub either pounds some decent bass or seems to shut off with a crossover.

I had a 2020 Tboss with the bose upgraded stereo and I now have a 2021 Denali HD. Same radio (as far as I know) and it has the same damn issue. The sub has a mind of its own. It comes on when it wants and it's great when it does, however it's not consistent and seems to work less of the time than more of the time. This is across the Genres of Country, Classic Rock, some of that EDM stuff and old school Rap. Any idea how to make the sub work 100% of the time? I have the bass all the way up, volume doesn't matter. I feel like it has a selective crossover but at times that selection is to just not work. Anyone else noticing this? If so is there a fix? Thanks in advance!

knowing a few people in the auto industry or just looking at stats... I'd say of the Big 3 GM is more than heads and shoulders above the competition. They are making "drivable" cars and putting them on the road. Ford's production is down 1/3 at minimum in terms of vehicle sales and they are screwing their suppliers by not fulfilling their orders with them and telling them to shove it. For instance their Chassis stamping is down almost 40% and they have no plans to pay their suppliers that let down despite being contractually obligated. So I believe what you are calling "cheap games" is GM making their vehicles run and at least fulfilling some kind of demand. They are the leader of this in the U.S.

I have a 2021 2500 Dmax and my power steering whines and groans like crazy!

This worked well for me as well. I did that and a quick booster test and now my brakes feel the same everytime I drive them with a nice firm pedal.

I feel the same way... If I lay on the brakes loaded or unloaded I stop very controlled and quickly. It just seems that the pedal travel to get to that point in consistent. I wonder if I should bleed the brakes.

I will try this and thank you!

I've found that making sure the exhaust brake is on helps.

Here in Michigan a dealer will go out of business if they don't accept GM discount. Get your vehicle from out of state and have it shipped to you. Those dealers are giving you the run around for no reason at all.

I follow your logic here and it shouldn't be dismissed. I've tested my brakes with and without trailer brakes and everything feels tighter when I'm towing. I have more feedback in the brake pedal and response just seems better. Sometimes coming up to a light (unloaded) I feel as if the TC isn't unlocking quick enough and torque of the motor is pushing it ahead. There are other times the brakes feel exactly the same and truck doesn't lurch... My head is going towards the TC not unlocking but I'm not a mechanic or expert so I could be way off.

@rRandom I feel exactly how you do and I had the same feeling in my 2020 TB. Brakes worked much better with a trailer attached, and I have to work more unloaded. Same exact feeling on my 2021 HD. I wonder if there is some kind of sensor that increases the pressure when it sense a trailer or load. I'd love to have an engineer respond to this because I do wish my brakes felt like they do when loaded all the time. Do they make an adapter to plug in that will make the truck think a trailer is attached? If so that'd be a great test.

I have a 2021 2500 Denali and my brakes are soft and feel very much like truck brakes with progressive braking power when I want it. My buddy's 2020 2500HD gasser has a much more stiffer pedal. Not sure why the difference but it's very noticeable. Mine feel fine, work fine, and I've already towed a few times with it and I have zero confidence issues and I tested my new trailer without trailer brakes vs. my half-ton... Stops almost unbelievably better coming from never owning more than a 1/2 ton before.

I've had a backflip MX4 on my last two trucks and like the flexibility of it. It will fold up against the cab with some spongy material so it doesn't damage anything and is held up by two little arms similar to a manual hood prop. It always seals fairly well and only leaks in extreme storms or a carwash. Even then it's minimal and while the definition doesn't fit here, I call that waterproof for a tonneau cover.

I get 9-11mpg towing a 7,500 TT with a half-ton 6.2 TB towing at 75mph. I just put a deposit down on 2500 Dmax as I feel it's much safer to have a bigger truck at this weight and speed regardless how good the 1/2 ton felt pulling the trailer.
