U1424 on Jeep
Implausible Engine Torque Signal Received
U1424 on Jeep vehicles indicates implausible engine torque signal received. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. 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.
Common Causes of U1424
- •Outdated PCM/module software needing reprogramming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
U1424 on Jeep by Model
Jeep Grand Wagoneer(2 issues)
- 360-Degree Surround View Camera System Glitches2022-2025
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.
- 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.
