What failed & is it available? The infotainment/radio module failed entirely due to an OTA software update (Codes: U18B4, U0184, B1325). The vehicle and component are fully available for inspection upon request. How was safety at risk? The federally mandated backup camera is now too faint/dim to read, destroying rearview visibility. Bluetooth/hands-free phone pairing is completely disabled, increasing driver distraction risks and preventing compliance with hands-free driving laws. Is it confirmed by a dealer? Yes. A local GMC dealership inspected the vehicle and confirmed the module is bricked, quoting $2,286.00 for a hardware replacement. Inspected by manufacturer/others? It has been inspected and confirmed by the local GMC dealer network, but GM corporate has refused to physically inspect or resolve it. Prior symptoms? No prior warning lamps or symptoms occurred. The system functioned perfectly until it instantly crashed during the remote update on August 10, 2026, at 9:00 PM.

Since we purchased our 2022 Acadia 6/24/2022 we have had the warning "Service Safety Restraint System" pop up randomly. We have mentioned it numerous times over the years when the vehicle has been in for routine service at our local dealership. They have never been able to determine the cause as no service code ever shows up for them. Today in addition to the warning the red air bag warning light also lit up briefly. The warning has popped up 2x in the last 2 weeks again with today being the only time we noticed the red light as well. We are now more concerned about the safety of our vehicle. (We will be on vacation now through 8/25 & would be available after that date for any contact)
