2025 9800 miles.. no issues at all.. love the fuel mileage !!

2022 1500 refresh LT Z71- 5.3 Without DFM. 45k I have one for the gurus, the problem Started about 5 or so months ago, We started getting a service Transmission message going into reverse. We Took it to the Dealer and they ran the codes, 1) P07B4 -Transmission park Position switch 1 Circuit High (ECM). 2) U0131 - Lost Communication with Power Steering Module (this is listed under the transfer Case Control module) I have been able to recreate the Service transmission message. When going into Reverse (only reverse), the errors come up if I don't pump the brakes first. If I pump the brakes 3 or 4 times and then put the truck into reverse, the errors don't come up. The service transmission message will throw the CEL, but after about 20-25 miles, the CEL goes out. Everything works fine, 4x4 High-low - power steering. One of the dealers I have taken it to said if I can live with it then drive it. I have searched on Google, there seem to be a few out there with the same issue. Some were fixed by replacing the rear brake actuator. has anyone had the same issue? looking for any advice. The dealer wants us to drop it off the truck for 3 to 5 weeks without a loaner.

Same issue here, 22 Refresh 1500 LT Z71 W/O-DFM... I had another issue with my Trk, The rear camera was replaced and the firmware was updated during that visit, all was good and everything worked. Fast forward 2 weeks later and the first of 2 OTA came through, Then the 2nd one about 5 days later, and that's when it all went to the dogs. same issue as above, running the fan, AC or not, it doesn't matter, the Radio burps and the fan speed drops just like I was on the phone, During this time I have noticed the steering wheel controls (volume and switch radio stations buttons on the back of the steering wheel) stop working. The radio will burp the 2nd time and then it seems like everything is back to normal with the controls, but the fan speed is still very low. I have to use the mute button on the steering wheel to mute whatever it is, and the fan speed goes back up automatically to where it should be. The update was GM QIHM22B-00708

I wanted to wait a week or two before I responded to the thread... My truck visited the dealer the other week, same issue as before, the rear camera would crash, reset, repeat, during the evening, low light. They replaced the rear camera, tested the coax cables, and updated the firmware, not sure to what version or if it's the same as the one listed before or not, my service writer didn't know. I'm not sure what was included with the update but, there are definitely some changes to the truck, things that I thought were normal NOW work normally, surprise 3 different features, and counting. So far, the issue with the camera has not come back, The video seems a "little" clearer.

Good news, maybe?!.. my truck visits the dealership Monday for this camera issue.

Same issue here, 2022 LT..
