2019 Ram 1500 Uconnect Screen Flickering and Freezing - Help!

Vehicle: 2019 Ram 1500 Laramie

Hey everyone,

My 2019 Ram 1500 Laramie's 8.4-inch Uconnect screen has been acting up lately. It started with occasional flickering, almost like a bad connection, but now it's freezing completely for several seconds at a time. Sometimes it even reboots itself while I'm driving.

It's really frustrating, especially when I'm trying to use navigation or change radio stations. I've tried doing a soft reset by holding down the volume and tuner buttons, but the problem keeps coming back. Has anyone else experienced this with their Ram, and what was the fix?

Could this be a software glitch, or something more serious like a failing module? Any advice would be greatly appreciated!

ClearTheCode admin answer:

Uconnect screen issues like flickering and freezing are common across various Ram models and can stem from several causes, ranging from software glitches to hardware failures. Here's a breakdown and troubleshooting steps:

Common Causes:

  • Software Glitches: Corrupted software or a need for an update can cause erratic behavior.
  • Loose Connections: Wiring harnesses behind the head unit or at the screen itself can become loose.
  • Failing Uconnect Module: The entire infotainment control module can develop internal faults.
  • Power Supply Issues: Inconsistent power delivery to the unit.
  • Overheating: Prolonged use or environmental factors can sometimes lead to overheating and temporary malfunctions.

Troubleshooting Steps:

  1. Perform a Hard Reset: Disconnect the negative battery terminal for 15-30 minutes. This can clear residual power and force a full system reboot, often resolving minor software issues. Reconnect and test.
  2. Check for Software Updates: Visit the Mopar Uconnect website or your dealership to see if there are any pending software updates for your specific Uconnect version. Updates often address known bugs.
  3. Inspect Connections (Advanced): If comfortable, you can carefully remove the trim around the Uconnect screen and head unit to check for any loose wiring harnesses. Ensure they are securely seated. This step is best left to a professional if you're unsure.
  4. Check for Diagnostic Trouble Codes (DTCs): While Uconnect issues don't always trigger standard powertrain codes, a professional scan tool can sometimes pull 'B' (Body) or 'U' (Network) codes related to the infotainment system. For example, a U0140 (Lost Communication with Body Control Module) could indirectly point to a network issue affecting the Uconnect.

When to See a Shop:

  • If the issue persists after a hard reset and checking for updates.
  • If you're uncomfortable inspecting wiring yourself.
  • If the screen remains completely black, unresponsive, or frequently reboots.
  • If diagnostic codes are present that point to a module failure. A dealership or a specialized automotive electronics shop can diagnose a failing Uconnect module or related wiring issues more accurately.
