This is a crying shame. This should not be happening to a truck that is only 4 years old. I might go back and just buy myself a Toyota Tacoma. This is happening to my 2019 trail boss and I am not impressed.

Yes, we've had 3 trucks and done them all with no questions asked. Our dealerships always tries to go above and beyond.

1/27/19 @ 5:35 am my truck threw this code.. "Service 4WD" after attempting to switch it from AUTO to 2HI. I was not moving, the truck was in neutral and I had just driven it the day before about 100

No.  They have their fair share of issues.  If you want a truck with fewer issues, go back about 10 years to the GMT-900s (without AFM) or even the GMT-800s.  Find a low millage and you'll have a GREA

Same issue... 2019 Custom Trail Boss... @1800 miles, towed to dealer as parking brake would not disengage (computer reprogrammed); 4100 miles, service 4wd and parking brake engaged, was able to get electronic brake to disengage (been at dealer for 2 weeks, replacing actuator and contacts).  Was given a loaner vehicle.  Hoping to get vehicle back soon and that this fix works!

 

11/16/19 -- vehicle still at dealer, waiting on "new connectors"!!!

This is exactly what's happening to my same year same truck. This is a crying shame. This should not be happening to a 4 year old truck. Might go back and buy a Tacoma next. I used to have a 2000 4runner and never had this problem no matter how old it was.

Sensors came in and they are currently installing them... hopefully thats the fix.....

Just found out this is the issue with my 2019 custom trailboss. Fixable. But my grind is why is this happening to a 4 year old truck? This is unacceptable. If this is happening everywhere, should this not be a civil suit? I mean they charge an arm and a leg for a new truck only to have it break down in 4 years?! This is so stupid already. 

Here's what happened so far to this "new" truck.

Oil coolant hose popped off. Had to get them to fix and was worried about internal damage.

Back up camera is dying.

4wd service.

Parking brake engaging automatically after I got the "service 4wd" sign. And they say it's not related to the 4wd. I think it is because that never happened until the 4wd service light went on.

Check engine light keeps going on periodically and then it's off again.

Wtf?

Apparently this is another issue that GM will stick their head in the sand and hope nobody notices that all of these issues are VERY similar!  Just like the poor quality lifters they put in their 6.2, 6.0, and 5.3 but GM wouldn't honor covering the fix when it was a known problem!  I spent over $5,000 on my 2015 Sierra 1500 with the 6.2 to put better quality lifters in that GM should have used to build their engines in the first place.  Now, I apparently made the same mistake purchasing a brand new 2025 GMC Sierra 2500HD AT4 that has 180 miles on it and I TOO am getting the Service 4WD message and the parking brake auto sets!  The weather has been very nice and I have YET to even try to switch out of 2WD.  So explain to me GM why this issue is happening!  COME ON GM!!!  Do better!  These issues are UNACCEPTABLE!  We do not have the time to constantly bring our vehicles to the dealer because your Quality Control/Quality Assurance, and company standards obviously suck.  Good thing Toyota doesn't make a 3/4 ton or GM trucks would be put out of business!  I believe a strong civil suit sits just within this thread alone and I'd bet this is just the handful of people who searched the issue out for themselves!  A good law firm will have a heyday with this.

      Tire psi

      By Chuck FB · Posted

      I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ).

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      Some Assembly is Required

      By Chuck FB · Posted

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
