    2019 AT4
  1. Chevy Shake

    I had the exact problem with my AT4. Brought it in and had the wheels balanced but it didn't help. They eventually found that the drive shaft had a dent! Replaced under warranty as I had it in for the shake shortly after I bought it. Rides smooth now. Hope yours is as simple of a fix.
  2. 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.
  3. 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.

  5. Anyone experiencing the following issue? 2019 AT4 I have set the radio to a maximum start up volume of 0 so that it is not on when I first start up my truck. About once a week when I start the truck, the radio thinks it's funny and pops on at half volume or more. I normally drop whatever I'm holding, spin the volume dial as fast as I can, restart my heart and go back inside my house to change my shorts. Anyone's radio being a jerk like mine? I've already had the truck in so many times for various issues, I'm just waiting for a few more issues to happen and do it all at once and waist less time.
  6. 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.
  7. Serice Steering Column Lock

    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.
