U0184 on Jeep
Lost Communication With Radio
U0184 on Jeep vehicles indicates lost communication with radio. Au7o has documented this code across 2 Jeep models — most commonly on Grand Wagoneer, Wrangler. 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 Jeep by Model
Jeep Grand Wagoneer(1 issue)
- Uconnect 12-Inch Touchscreen Freezing and Black Screen2022-2025
The Grand Wagoneer's 12-inch Uconnect 5 infotainment system experiences frequent freezing, black screens, and spontaneous reboots. The system may become completely unresponsive, disabling climate controls, navigation, backup camera, and vehicle settings that are exclusively managed through the touchscreen. Stellantis has released multiple over-the-air (OTA) software updates to address stability, but the issue persists for many owners. The McIntosh audio system amplifier can also contribute to system instability.
Jeep Wrangler(1 issue)
- Uconnect 4/5 Touchscreen Freezing, Reboot Loops & Backup Camera Blackout2018-2024
The 8.4-inch Uconnect 4 and the newer Uconnect 5 head units frequently freeze, glitch, reboot multiple times before booting, or go to a black screen. A common and safety-relevant failure mode is the rear backup camera failing to display when shifted into Reverse, showing a blue/black screen, or staying on after moving forward. The system is sensitive to 12V voltage drops (a weak auxiliary/aux battery makes it lag, reset, or refuse to boot), and many JLs ship with loose fuses that aggravate the problem. Stellantis acknowledged a broad list of Uconnect 5 failures across 2021-2024 vehicles in Technical Service Bulletin 08-008-24.
