Exact thing just happened to my truck at 32000 miles and they said that a rock or an object must of got stuck in the pad causing the gouge in the rotor. The message I got on my dash was not to replace pads...it says Service Brake Monitoring System. Which to me means the monitor malfunctioned. So now they want 700 to fix the back brakes. Funny thing is that it showed 89% left right before the error showed up on my dash. Could you please provide any more detail as to what was covered and what you replaced it with. I am unsure what I should do next as I really don't think this is my fault and due to the brake monitor malfunction any damage should be covered under warranty. Thanks.

Please, please share this mod. I would love to keep mine in Sport mode as I keep forgetting to turn in on!

Thx. Tires are louder than stock, but not super loud or annoying. I bough them because they are XL rated and not LT so they weigh about the same as the stock tires. I towed my camper all last summer and they performed great. I would buy them again. Seem to wear great too. Made the stickers myself on a vinyl machine.

Nitto Ridge Grapplers 275/60-20XL

Put my AMP bed extender from my 2018 Denali onto my At\4 with Milti-pro gate (not carbon bed) and installed and works exactly as it should. No problems at all.

Not the same: x31 and z71 come with twin tube ranchos......AT4 and Trail boss come with different monotube Ranchos (upgraded).

I have a '21 AT4 with the 20" All Terrains and it has Sport mode. It's hard to believe that they would remove a feature just because someone choose the 18 Duratracs. Are you in 4x4 mode, maybe sport is only available when it is in 2wd High. Now I am going to have to check!

Mine has the wireless charging too. Just set it down, charges and connects wirelessly to Android auto. On a side note, my Google Pixel has worked flawless with Android Auto, while my daughters iPhone music gets choppy every once and a while. After having it both ways, I would not go back to a cable.

I too have had the Adaptive Cruise suddenly turn off exactly as the OP posted. Once I was driving with the Adaptive Cruise on with no vehicles ahead of me and the the seat vibrated, lights flashed, and disabled the cruise for no apparent reason. Second time I was on the freeway and the adaptive cruise was working fine for an hour or so, then as I was approaching a slower vehicle in my lane waiting for the adaptive cruise to adjust my speed to match the approaching vehicle the Adaptive Cruise suddenly shut off exactly the OP stated and I had to press the brake to slow down my vehicle. In BOTH situations, the Adaptive Cruise would not turn back on and I had to switch to regular cruise for the rest of the trip. After I restarted the truck after a stop the Adaptive Cruise starting working again. Definitely a malfunction of some sort.

I too installed the CURT Tailgate Hitch Solution. Plugs into the existing harness, no splicing wires, clean look, and works great so far.

I was in the same boat as you and the choices are very few options if you do not want a SL or LT E rated tire. If you want to something bigger than SL, but do not want an LT tire....than you want an XL tire. I have run XL rated on my last 4 trucks and find them the best compromise between SL and LT tires. Almost the same weight as an SL tire but extra strength in the sidewall for towing and stability. I was in the same situation as you and just got Nitto Ridge Grappler 276/60/20 XL tires (they also make them in LT in that size) and I love them so far. They look a bigger than the Trail Runner ATs and definitely more aggresse. Look like what the AT4 should of came with. If you want something less aggressive they also make their other AT tire, the Terra Grappler G2 in the XL rating. There are very few XL tires in that size, others being Cooper LTZ and I believe a highway tread tire in the General Grabber H series (I think). The only other option is Hankook AT, BFG KO2 and General Grabber ATx are all made in D instead of having to go to an E rated tire. I will try and get a pic for you and post it here.

I actually have the tool from Amazon due to me changing from Winter to summer wheels on my truck. The GM sensors are much more expensive purchased from the dealer than when ordered with a truck. Only $50.00 option if ordered, Was hoping to find someone with he GM ones they didn't need and wanted to sell. I can purchase aftermarket for around $80-$90, but was hoping for real GM, not aftermarket. Thanks.

Looking to add the Tire Pressure Sensors to each of the 4 wheels of my RV. If anyone's truck came with these and you do not need them, please PM me

Yep.....They sent me the wrong connector too. Mine was an extender like the one you posted instead of the T-tap it should of cam with.

Absolutely agree. My '18 Denali had the 5.3 w/ 8 speed and when upgrading to a '21 I had my heart set on the 3.0 or the 6.2. I drove them all, BUT once I test drove the 5.3 with the 10 speed I felt like it was a totally different engine compared to my '18. Very happy with the 5.3....now!

<Coming Monday Ridge Grappler 35x11.5 What tires are on it now? In the 2nd pic they already look like Ridge Grapppler's. Are the Ridge Grappler's going to be LT or the XL Load range? Looking to do the same on my stock 20s.

Thanks for posting this....I have been seeing it on my screen in the morning for the last couple of days. (5.3 V8)

Just called to cancel and asked about Costco/Onstar discount for Remote Access. She just kept reading multiple discounts available and I asked about a prepay for one year and she offered me $68.20 for a year subscription, which works out to about 5.68 month. I could of signed up for a 2 or 3 year for $8:13 month, but I took the 1 year....for now.

I have the same CK160s wheels but did not fit my AT4 due to the calipers. Did you puts spacers? What size? Do you have any more pics showing the stance or how much the wheels stick out past the fenders.

Yep, my 2018 with 31000 miles had a bad starter. was on national backorder at that time if that tells you anything ?

Looks Awesome! I think the BFGs are D rated LTs. I am Curious how the LT tires compare to the Ps that came with your truck as I would like to do the same. Would you mind sharing your experience with them regarding weight, ride, and gas mileage?

Could you please elaborate on these tires as I am thinking of going the same route. Mainly concerned about the ride of the D rated vs the P rated OEM tires. weight and fuel mileage. I really love the way the truck is now....except I tow a camper during the summer months and am unsure about the OEM tires!
