U0184 on GMC
Lost Communication With Radio
U0184 on GMC vehicles indicates lost communication with radio. Au7o has documented this code across 1 GMC model — most commonly on Terrain. This network code means a module stopped receiving expected communication messages from the radio/audio module over the vehicle's data bus. When the radio module goes offline or its bus connection fails, this code is logged. On some vehicles the audio module also acts as a network gateway, so its loss can trigger several related communication codes. Symptoms are typically a dead or unresponsive radio/infotainment system; it does not affect drivability. Typical repair costs on GMC range from $100 to $900, depending on the specific model and root cause.
Common Causes of U0184
- •Loss of power or ground to the radio/audio module
- •Blown radio fuse
- •Wiring or connector fault on the communication bus
- •Faulty radio/audio control module
- •Corroded or loose module connector
- •Network/bus wiring short affecting multiple modules

- IntelliLink Infotainment Freezing/Rebooting and Backup Camera Black Screen2013-2019
The IntelliLink/MyLink touchscreen freezes and spontaneously reboots, losing control of radio, climate, navigation and Bluetooth, and often displays a black screen or a frozen backup-camera image. During a reboot, phone calls drop and the rear camera can go dark while in reverse - a visibility concern. Root causes include software glitches, outdated firmware, and occasionally loose display/camera wiring.
