“I am filing a safety complaint regarding my 2022 GMC Terrain after experiencing a sudden infotainment system failure that also disabled my backup camera functionality.

NHTSA complaint #11655739, filed 2025-04, 22,000 miles“The vehicle experienced a complete loss of infotainment/audio functions immediately following a GM over-the-air software update. The OnStar indicator turned red, all vehicle audio including turn-signal sounds stopped functioning, and the rear backup camera stopped displaying an image. The backup camera failure creates a safety concern because it eliminates a federally required rear visibility safety feature. GM has advised me that software updates do not cause these problems and instead reveal an underlying issue. …”
