U0184 on Chevrolet
Lost Communication With Radio
U0184 on Chevrolet vehicles indicates lost communication with radio. Au7o has documented this code across 4 Chevrolet models — most commonly on Colorado, Equinox, Silverado 1500. 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.
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
U0184 on Chevrolet by Model
Chevrolet Colorado(1 issue)
- Infotainment System Freezing/Rebooting2015-2021
The MyLink infotainment system can freeze, become unresponsive, or reboot randomly. This affects the radio, navigation, backup camera display, and phone connectivity. Issues are often software-related but can indicate hardware failure.
Chevrolet Equinox(1 issue)
- Infotainment / MyLink Display Goes Black or Reboots Repeatedly2018-2024
The center touchscreen (Chevrolet MyLink / Infotainment 3) intermittently goes completely black, freezes, or reboots in a loop while the rest of the car operates normally. Owners lose the backup camera, climate display, radio, Apple CarPlay/Android Auto, and OnStar screen. The failure is usually a software/HMI-module fault but is also commonly traced to loose or corroded connectors and cables at the radio receiver located behind/below the glove box, or to a failing HMI (Human-Machine Interface) display module. A temporary fix is a system reboot (hold the power/volume knob ~10-15 s, or hold Home + fast-forward for 10 s), but it returns until the underlying module or wiring is addressed. This is one of the most-searched Equinox electrical complaints across model years.
Chevrolet Silverado 1500(2 issues)
- Infotainment Screen Freezing/Black Screen2019-2023
The infotainment system can freeze, display a black screen, or reboot randomly. This affects navigation, audio, backup camera, and vehicle settings. Software bugs and hardware failures are both possible causes.
- Google Built-in (13.4-inch) infotainment freezing, lockups, and audio dropouts (2022+ refreshed cabin)2022-2025
Trucks with the larger Google Built-in infotainment system (rolled out on the refreshed 2022+ Silverado 1500 interior and continuing through 2024-2025) suffer frequent screen freezing, full lockups, Bluetooth dropouts, navigation errors and streaming-audio (e.g., Spotify) lockups. Owners commonly have to switch the ignition off and wait several minutes for the head unit to recover. Internal GM bulletins attribute many freezes to the system being overloaded when processing too many tasks at once, and to communication errors between the infotainment system and the body control module. This is a newer-generation, Google-OS-specific complaint distinct from earlier MyLink/Infotainment 3 freezing on pre-refresh trucks.
Chevrolet TrailBlazer(1 issue)
- Infotainment System Freezing and Rebooting2021-2025
The Chevrolet Infotainment 3 system freezes, goes to a black screen, or reboots spontaneously. Bluetooth connectivity drops and Apple CarPlay/Android Auto connections are lost. The system may become unresponsive to touch input, requiring a manual reboot. Software stability issues have been addressed through multiple OTA updates.
