Jeep Grand Wagoneer · 2022–2025
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.
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.

Jeep Grand Wagoneer · 2022–2025
The Grand Wagoneer's 360-degree surround view camera system displays stitching errors, frozen images, distorted perspectives, and intermittent black screens. The system uses four cameras (front, rear, and both side mirrors) composited into a bird's-eye view, and the image processing frequently produces visual artifacts. Individual cameras may fail to initialize, leaving blank quadrants in the surround view. The issue is exacerbated in cold weather and after OTA system updates. The Night Vision camera (if equipped) has separate but similar reliability concerns.
Common Symptoms
- Distorted or warped surround view image
- One or more camera quadrants showing black
- Stitching errors where camera views meet
- Camera system fails to activate when in reverse
- Frozen or lagging camera image
- Night vision display intermittent (if equipped)
How to Fix
Ensure all four camera lenses are clean — dirt, ice, or water droplets cause stitching errors and distortion. Perform a Uconnect soft reset (hold power knob 10-20 seconds) to reinitialize the camera system. Check for and install any available OTA updates (Settings > Software Update). If specific cameras consistently show a black image, the individual camera module may need replacement (front: 68488165AA, rear: 68488166AA). Side mirror cameras require mirror cap removal for access. Dealer calibration of the surround view system is required after any camera replacement.
Owner tips & cautions
- TipBefore going to the dealer for camera issues, try cleaning all four camera lenses with a microfiber cloth and glass cleaner. The front and side cameras are especially prone to salt spray and road grime that causes the stitching algorithm to produce bad composites. 30% of camera complaints are just dirty lenses.

Frequently asked questions
What does U1424 mean?
U1424 stands for "Implausible Engine Torque Signal Received." U1424 is a manufacturer-specific network/communication code reported on Ford and Chrysler-family vehicles. It indicates that a control module received an engine torque value over the data bus that is implausible (out of expected range or inconsistent with other inputs). This often points to a software calibration mismatch or a sensor/module sending bad data rather than a single failed part. On many vehicles the fix is a PCM/module software update, though wiring and sensor faults can also cause it.
What are the most common causes of U1424?
The most common causes of U1424 are: Outdated PCM/module software needing reprogramming, Faulty sensor feeding torque calculation (e.g., throttle, MAF/MAP), Network/CAN bus wiring fault or poor connection, Mismatched or improperly flashed control module, Intermittent module power or ground issue, Failing PCM/ECM. The specific cause varies by vehicle.
How much does it cost to fix U1424?
Repair costs vary widely depending on the root cause and vehicle.
