Nope, not throwing money at Onstar to use their app but would if it was free like it used to be. Going on 9 days now without issues!

I just had the newest one done yesterday -the update to fix the fix for the fix for the recalls. So far 36hrs and no problems!

I had the latest recalls done. Anyone else's lane keep assist go nutz afterwards? Dealer said that they had two others with the same issue. At least my brakes work... for now...

Taking advice not to get the recalls, been waiting for a few weeks for them to get sorted out and they still can't get them right. I've had such bad luck with this truck that I wouldn't be all that mad if the brakes failed and the truck found the nearest tree, personal injuries aside.

Ever since they replaced that usb-c plug under the radio it has work fine ever since. I believe there should be a tsb on it. Time to schedule your appointment!

Had the same problem with mine... After a tire rotate and rebalance didn't work the dealer found what the issue really was. The driveshaft had a dent! They replaced the driveshaft at no cost since the damage came from the factory. Hope you can find your gremlin!

Throw in 300# of sand in the box, you will get the level you want, cheaper, easier to install, more traction in the winter and it's easily reversible if you don't like the look! .02$

Just push the button on one side of the base and wiggle the head rest out, it's a little tight. I pulled the bars apart a bit when I switched then around and all was good when I put them back in.

I did the same and it worked for me too.

Brought mine in for this issue about two months ago. In the end, the dealer replaced the card, card reader, whole radio unit, and the USB/USB-c plug under the radio. They managed to finally fix it but it took two weeks for ordering various parts and stuff. Just for fun I asked what they do if all this didn't work. They said they still had one more option which would be to put in a new wiring harness. Luckily, they didn't have to do that.... yet. No problems now for two weeks now.

I went from a 2017 HC to the 19 AT4, I'm 5'9" and without the tailgate down, there is no way I can reach anything in the box from outside when standing in the ground. The new trucks are definitely taller. I love the extra height when driving around, able to see the roofs of most other vehicles.

There is a service bulletin on the 8sp transmissions for your issue. I had a 17 HC with this and I had it serviced several times for this issue. It drove me crazy until I finally traded it in. There is no fix but they may do a relearn on yours like they did on mine. It helped for a few weeks but returned to the normal harsh shift between 1 and 2 upon the first start up if the day. Unfortunately they told me that the transmission was "operating as designed". If you keep your truck look into an aftermarket tuner.

500 on my AT4 and I have this also. It only comes on when I use the onstar app to autostart it. I have an appointment at the dealer to have it checked out next week. If there is no fix yet it still needs to be documented.
