GVW Error (Gross Vehicle Weight) when towing

[AliBaba]

Has anyone else seen this error when towing? I'm towing a 5,100lbs boat trailer with 550lbs tongue weight. Vehicle only has 4 people in it and all the gear is in the boat. I've had it weighed and am no where near my max trailering weight of 8400lbs. Dealer has no idea why i'm getting it either. Basically, the car things it's overweight and yelling at me.

My only thought: I have air ride suspension and i have lifting links that took me up .5" to get a cleaner ride. I'm wondering if while daily driving the car thinks I've just always got more stuff since it has a higher PSI to keep it at the set height BUT when i'm towing it's putting so much air to keep it there that it thinks it's overweighted.

My next step is to swap to my original links and test that theory but that's going to require a free weekend day to play with that. Otherwise I'm at a total loss.

I’d 100% return to stock configuration before messing with anything else….. good luck.

I think that your theory is correct. Let us know the results.

The lift links are def messing with your calibration. Or the trailer is not entered correctly in the app.

I take it you can't just turn that nanny off?, seems like you should have a check box in the settings to uncheck and carry on

I don't know anything about lift links or air ride suspensions but I hope that's causing the problem and it's easily remedied.

If it doesn't, I'd re-check your weights to make sure you haven't exceeded your Tahoe's GCWR. It sounds like your rig had quite the load.

Well I put the factory links back in and when that GVWR toggle is on it still tells me I’m over weight. Tongue weight (measured) is 650lbs fully loaded and the trailer is about 6200lbs. Both are well within the 8400 max towing for my Yukon XL.

It’s going into the dealer on Wednesday to have them take a look BUT yes you can turn it off. The question is WHY is it thinking that.
