U0184 on Jeep by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Touchscreen completely frozen or unresponsive
- Screen goes black while driving
- System reboots spontaneously (showing Jeep logo)
- Climate controls unresponsive (managed through screen)
- Backup camera fails to display
- Bluetooth audio stuttering or disconnecting
How to Fix
First, perform a soft reset: press and hold the Uconnect power/volume knob for 10-20 seconds until the screen goes black and reboots. If the issue persists, visit the dealer for the latest Uconnect 5 software update (check for TSB 08-135-22 REV. C or later). Ensure the 12V battery is in good condition — low voltage causes Uconnect instability. Some owners have required a full head unit replacement under warranty. Disable unnecessary background apps and features like SiriusXM 360L if stability issues continue.
Owner tips & cautions
- TipBefore going to the dealer, try a hard reset: disconnect the negative battery terminal for 30 minutes, then reconnect. This fully resets the Uconnect 5 system and clears corrupted cache data. About 50% of screen freeze issues are resolved by this simple reset.

The 7.0-inch and 8.4-inch Uconnect 4 head units in the Gladiator intermittently lock up, reboot in a loop, or drop the rear camera feed - the screen goes black when reverse is selected while the rest of the radio still works. Owners report the fault appearing after a software update, after a battery replacement/disconnect (the radio loses its vehicle configuration), or spontaneously with no trigger. Because the backup camera is federally required equipment, a permanently blank camera is a safety-inspection failure, not just an annoyance.
Common Symptoms
- Backup camera shows a black screen in reverse
- Uconnect screen freezes or reboots while driving
- Radio loses audio or Apple CarPlay/Android Auto drops
- Screen stuck on the Jeep logo
- Fault appears after a software update or battery disconnect
How to Fix
First try a hard reboot: hold the radio power button roughly 20 seconds, release and hold again, or pull the radio fuse (F97 in the underhood PDC) for 10 seconds with the engine running. After a battery disconnect, the radio may need several key-off hours to relearn the vehicle configuration. If the fault repeats, have the dealer flash the latest Uconnect software and inspect the camera harness/connector at the tailgate - persistent cases end with head unit or camera module replacement, covered under the 3yr/36k warranty.

Uconnect resets or a blank screen, intermittent accessories, a discharged battery, and communication faults may occur together, but they do not establish that the Body Control Module is defective. Radio software or hardware, a weak battery or charging problem, poor power or ground, damaged CAN wiring or terminals, another module that will not sleep, and a true internal module fault can overlap. FCA has a software bulletin for specific early 2014 WK vehicles with RA3/RA4 radios, including radio resets and radio-caused battery drain, but that bulletin is sales-code and build-date specific and does not justify replacing a BCM, Intelligent Battery Sensor, or battery on every 2014-2018 vehicle.
Common Symptoms
- Uconnect radio resets, locks up, goes blank, or responds slowly
- Intermittent accessory or warning-lamp behavior
- Battery is discharged after the vehicle sits
- One or more modules store lost-communication faults
How to Fix
Start with a complete vehicle scan and save active, stored, and environmental data before clearing anything. Load-test the battery, verify charging voltage, and repair low-voltage faults first. Inspect the relevant fuses, power feeds, grounds, connectors, and CAN wiring, then measure key-off draw only after the vehicle has completed its normal sleep period and isolate the circuit that remains awake. For radio resets, identify the exact radio sales code and vehicle build date and check the VIN for the applicable FCA software or radio procedure. For a lost-communication fault, determine whether the named module is actually offline, whether multiple modules logged against it, and whether its power, ground, and network circuits pass before condemning it. Replace and VIN-configure a BCM, radio, IBS, or battery only when the component-specific test proves it failed.
Owner tips & cautions
- WarningU0140 means communication with the BCM was lost; it does not prove the BCM itself failed. Voltage, power, ground, wiring, network, and reporting-module faults must be separated first.
- TipAsk the shop to show the sleep-current measurement, the circuit that stayed awake, and the network scan before authorizing an expensive programmed module.

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.
Common Symptoms
- Touchscreen freezes / unresponsive buttons
- Radio reboots 3-4 times
- Black or blank Uconnect screen
- Backup camera blue/black screen in Reverse
- Camera image lingers after moving forward
- CarPlay/Android Auto dropouts
How to Fix
Reboot the head unit (hold volume + tuner knobs ~10-20 seconds) and reseat fuse F97 to clear a frozen state. Apply the latest Uconnect software update per TSB 08-008-24, which addresses many freeze/reboot and camera bugs. Check and tighten loose cabin fuses and verify the auxiliary/12V battery health, since low voltage triggers resets. If the backup camera still blanks, inspect the camera, its harness, and connector; replace the camera or radio module if a hardware fault is confirmed.

Frequently asked questions
What does U0184 mean on a Jeep?
U0184 stands for "Lost Communication With Radio." 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. On Jeep it is documented across 4 models: Grand Wagoneer, Gladiator, Grand Cherokee, Wrangler.
What are the most common causes of U0184?
The most common causes of U0184 are: 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. The specific cause varies by vehicle.
How much does it cost to fix U0184 on a Jeep?
