NHTSA Complaint #11667911 — 2024 GMC TERRAIN

infotainment system safety issues. I have video. Multiple times per week when starting the car and backing the rear camera engages. When placing car in drive the rear camera never shuts off, the sound volume doesn't work, the entire infotainment system completely malfunctions. The safety is when attempting to function the controls the volume will turn up and not able to turn it down, the screen flashes and the infotainment systems controls on the steering wheel do NOT function. I've had it to the dealer and they indicate PIC6591A from March 3rd 2025 is logged. When contacting GMC corporate they refuse to give any information. The PIC spans across many GMC vehicles including 2019 models. Why hasn't this been addressed? My son drives a 2024 Chevy Trax and this car has no issues like the my car does. His car also doesn't have the transmission/gear shift buttons like the 2024 terrain does. Anyone else having issues with the GMC infotainment systems, black screen, malfunction? I have video.
