Took my 2021 Silverado 1500 into the dealer for this problem as my warranty expires this month. They had the truck over two weeks and had to make several calls to GM before they finally fixed it. It had the latest software, but they said they had to reflash multiple computers across the vehicle, not just the radio.

I just put the B8 5100s on my 2021 Silverado 1500 after 30,000 miles. These should have been my first mod! What a transformation. Rather than experiencing highway bumps three times after you hit it, the truck just sucks these up.

Anyone know where the inverter is located and if you can swap it out for a bigger one?

I specifically asked the dealership doing the first free oil change if it was a synthetic oil and it was, so free synthetic oil is hard to beat.

I used a different dealership. They did the tire rotation, but did not adjust tire pressures or register the tpms sensors in the new locations. I figured that out once it started to get cold outside and I needed to add air to the tires. Luckily I have a tpms tool and fixed it myself. So check the dipstick and tire pressures when you get home.

Both my front door handles with the grey wood on my 2021 LTZ were destroyed by bug spray on the driver and passengers legs touching them, melting the glossy finish. Right side front: 84631247, crew door: 84631265 Left side front: 84631246, crew door: 84631259 GM Parts Direct says these are Anteak.

This was pushed to my truck OTA. It does show up in the Update History.

The Chevrolet Connected Vehicle plan includes live traffic and map/POI updates on the nav and it is $10/month full price.

My 2021 LTZ has USB ports inside the armrest. They are near the front on top by the SD card slot and there is a nice gap left to have cables pass through with the armrest closed. USB Port This vehicle is equipped with two USB ports in the center console under the armrest and another two in the center stack. These ports are for data and charging. There may also be two USB ports for charging only at the rear of the center console.

My 2009 Silverado did something similar so I parked it and had it towed unnecessarily -- dealer said the fuel tank sender shorted out the CAN buss. Only a couple gauges were affected, not all.

I have this cover on my 2021 Silverado and everything works perfectly, both automatic opening and closing. VANISH Roll-Up Truck Bed Cover | Low Profile Tonneau Covers (accesscover.com)

Exactly. You can run stiffer springs and shocks to control body roll at the expense of ride quality. My Silverado 2500 HD had very little body roll because it was sprung for heavy loads. My Silverado 1500 with softer springs and upgraded sway bars has very little body roll now too, and it rides much better than my Silverado 2500 HD.

I decided to install the Hellwig 7781 front sway bar as well on my 2021 Silverado 1500 Crew Cab Short Bed. Not as big as an improvement compared to adding the rear sway bar, but still very significant. Since it's cheaper that makes it a worthwhile investment. Also much easier to install since there already is a sway bar there. Now you can really tell the all-terrain tires are the weak link.

As truck mods go, I give this one a 10. Well worth the cost and the effort. I took Rook126's advice and used the stiffest setting. Now the suspension will take a set in less than half the time it took before and inspires much more confidence.
