Today while towing my travel trailer with my 2022 chevy 1500 lt duramax, I got this message display on the dashboard (dic). Warning vehicle/trailer weight may exceed combined gross vehicle weight rating. Any idea what cause this warning message to display? I know the weight of the truck and trailer are way below the gcwr, same for the tongue weight. Thanks for your input.

I get the same message on my dash information center. I went to the scale and noticed I still had 2500 lbs before I hit the 15,000 GCWR. I also have a 2022 Silverado LT Crew Cab with he 5.3 engine. I have pictures of my weight at the scale with trailer and my information plate from the door of the truck. In case you have issues I will list my weights below:

 

Steer Axle: 3200 LB

Drive Axle: 3240 LB

Trailer Axle: 6060 LB

Gross Weight: 12500

 

My information plate states:

GAWR FRT 3800 LBS

GAWR RR 3800 LBS

GCWR 15000 LBS

 

Any answers on why this is happening? I will also email you the information.

Do you guys have a leveling suspension out back by chance?  The computer knows it should squat so much at such weight and may be the case.  TFL Truck saw this message but I do not remember if it was for GM pickups.  We're still running leaf springs and regular shocks right?

I wonder if it sensed being ''close'' to the limit in GM's mind to cover their butts, so it set the warning. Lots of folks towing over their head so it may default to an early warning for the ''average'' owner, not experienced folks who actually scaled their rig. 

I'm wondering how system figures this out. Calculates throttle input, road speed, what gear it's in and factors all of that together?

I got the same message with my 2023 Silverado 1500 with the 6.2 and my GVWR is 15000 and the total weight of what I'm towing plus the truck cargo and passengers is 13200.

I also received this message on my 2022.5 GMC 1500 with the 2.7.  I know for certain my trailer is not over gross with the weight of the truck. I didn’t receive this type of message until a recent technical update was done. I’m assuming when I last took my truck in for a recall fix. At that point they did an update to the trailer brake that previously was not working. I typically get the code when accelerating, such as from a stop sign at an incline or when the wind is dragging, or when on the interstate even at lower speeds. 
I am very concerned this is to void a future warranty claim. The very reason I purchase new vehicles. 
 

I certainly follow the manufacturer guidelines such as higher octane gasoline but I’m definitely concerned that GM is looking for an excuse.

Traded for a '23 which has this feature, so thought I'd look up what the manual says about it. 

(I haven't towed yet...)

 

 

Gross Combined Weight (GCW) Alert

 

If equipped, the GCW Alert can display a message in the Driver Information Center (DIC), indicating that the estimated
combined weight of the vehicle and trailer may exceed the vehicle’s GCWR, under certain circumstances. See “Gross Combined Weight Rating” above.

 

The vehicle does not actually measure the loaded weight of your vehicle or trailer.

It uses vehicle data to estimate these weights after you begin a trip.

 

The alert will not activate unless:
. The feature is turned on in the trailering application. See Trailering App pg 321.
. The vehicle-trailer combination have been used enough together for the software to estimate the combined vehicle and trailer weight.
. The estimated weight could exceed the vehicle’s maximum GCWR. 

 

 

and from the Trailering App section (app info starts on page 321, this is from pg 327)

I Just bought a ‘22 Silverado Refresh 1500. Before installing air springs I towed the same trailer with the same weight (well under GCVW and conventional trailer weight) and had no alerts. Installed air springs and now I get the warning (conditions unchanged except air springs). I am assuming that they have something to do with the calculations the computer is making. 🤷‍♂️

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
