Please consider that most cameras are mounted without a plug near the camera. Having a dongle hanging from an Airstream rear camera would not be an appropriate fix.

They don’t have a hardwire option for anything but the Denali.

GM left it as "We understand that you were promised a trailer camera but we don't have a solution for you, you will need to discuss this with your sales team at your dealership, or you can try various third party devices that may provide similar capabilities." The Echomaster guy was excellent and gave me some ideas to try regarding remote antennas on the trailer but said he is not aware of any camera that will not have the interference from the TPMS as an issue as they are all made by same Chinese companies. Don't direct wire your camera, that will not fix this issue and you will be wasting money.

I have gone down the rabbit hole on this issue and talked to all levels of GMC even Echomaster support. The 2019 IOT Radio system in the SLT and Denali, was not developed by Echomaster and they had no input unlike other model years and even lower models of current year. GMC system they did internally is not compatible with wireless cameras for 2019. The TPMS system they decided to use is generating interference in the same wireless range as the cameras. The solution they used for Denali was to install RCA plugs in the back (admission of the issue) and expect people to run a wire to the back of the trailer to avoid the interference so they could keep promoting the trailer integration features. This is not a solution for something like an Airstream where running wires is not easy. They did not install the RCA plug in the other non Denali models with the IOT Radio so they have no towing camera option solution to hardwire it. The interference seems to be across the 2.5 to 5 Ghz range, so no aftermarket wireless system will work that uses that range (being all but wifi systems). Echomaster said to try and run an antenna from the rear camera to the front of the trailer to see if it will cut thought the TPMS interference. I just order a wifi based camera that connects to the phone, but this is not what was promoted by GMC! No integration. You can build the truck with the hard wired camera as an add-on online, but it does not really exist and does not ship on the non Denali trucks. Not a Happy customer! GMC will need to make a custom camera that can handshake with the bastardized version of bluetooth they implemented in the IOT radio system to avoid the interference. I doubt this will happen! Hopefully I saved people the 5+ hours of phone calls to arrive at that answer.

I sure hope we were just an anomaly, but it does not make us feel good going forward.

Our truck with only 6,200 miles bent a pushrod already. We are concerned as the dealership already had a notice of the known issue. They fixed it but worried it was not a real fix, just a replacement of the defective design. Has anyone else had this problem on the new 2019 Sierra 6.2L. Would love to know how big an issue this is.

Having the exact same issue on 2019 Sierra. Voyager camera turns on for a second every few seconds. Hope we can find a fix!
