When I had mine replaced under warranty, advisor said the module was behind the backseat and they had to remove it to change out the module. But once they did that, an error code on a sensor came up, they then replaced that sensor and it's worked fine ever since.

I have finally got mine fixed. Dealer had to put in a new park assist module, which then gave them an error code for a front sensor. Once they replaced the front sensor, all works fine now. Good Luck

just wondering if you've had any luck with this issue? I'm still fighting it.

I'm having the exact same issue. The park assist on these trucks has always been crap. I had a rear harness replaced a few weeks ago, and it worked for a couple days, now the same thing you said above is happening to mine. I've reached out to my service advisor, I'll report back if i find a fix

I put my rev tonneau cover off my 2016 Sierra short bed onto my 2020 and it fits just fine. Sent from my iPhone using Tapatalk

I have the exact truck! I have a 1.5" level with 275/60 bfg's and HD Gator Back Mudflaps. My tires sometimes rub on the bolt heads holding on the flaps at full lock. BTW which in channel visors are those? I tried the AVS ones and couldn't get them to work.

I use a WDH hitch as well, always have towing anything 5k or more. It’s common sense to use one, or should be. Air bags add that extra help on the ride, bounce, sag, etc. Sent from my iPhone using Tapatalk

I pull about the same trailer. I have these airbags: https://www.airliftcompany.com/shop/89288/ And this compressor: https://www.airliftcompany.com/shop/25980ez/ It’s a nice set up. Really like being able to adjust the pressure as I go. Easy for hooking on and unhooking, etc. Definitely worth the $ if you tow lots. I tow every 2nd weekend or so. Wouldn’t go without this set up.

I have bags on mine for pulling my RV. Also have an wireless One On-board compressor for quick, easy adjustments. Highly recommend. Easy install. Wouldn’t tow with air bags. Have had then in my last 3 trucks for towing. Sent from my iPhone using Tapatalk

I have a GMC duramax. I tow a 28’ wilderness 2475BH, approx 6500lbs loaded up. Pulls great, Tons of power. Most of my towing had been on relatively flat terrain. Avg over 1000miles, 12mpg. Sent from my iPhone using Tapatalk

What’s the part number? And how much did they cost? I have a 2020 slt duramax and would like a set. Power, blind spot, etc w/ no camera Sent from my iPhone using Tapatalk

Depends on the loaded trailer weight but the 6.2 w/ 10sp will make light work of that trailer Sent from my iPhone using Tapatalk
