Symptoms and warning signs

The primary symptom is, of course, the 2020 Charger Uconnect display blinking on and off. However, this can manifest in several ways and be accompanied by other indicators:

  • Intermittent flickering: The screen rapidly flashes on and off, or shows distorted images.
  • Complete blackouts: The screen goes dark for varying periods, sometimes returning on its own, sometimes requiring a vehicle restart.
  • Touchscreen unresponsiveness: Even when the screen is on, it may not register touch inputs.
  • Loss of integrated functions: Navigation, radio, Bluetooth, and climate controls (if screen-based) may stop working or become unreliable.
  • System reboots: The Uconnect system may spontaneously restart while driving.
  • Error messages: Though less common, specific error messages related to the infotainment system might appear.

How to verify and confirm the issue

Before diving into complex repairs, it's crucial to verify the issue and rule out simple causes. Here's how to confirm the problem in your 2020 Dodge Charger:

  • Observe patterns: Note when the flickering occurs (e.g., over bumps, after starting, in hot weather). This can provide clues.
  • Soft Reset: Perform a soft reset of the Uconnect system. For most 2020 Chargers, this involves holding down the volume and tuner knobs simultaneously for about 10-20 seconds until the screen goes black and the Uconnect logo reappears. This can resolve minor software glitches.
  • Check Fuses: Locate the fuse box (often under the hood or in the passenger footwell) and inspect the fuse(s) related to the radio/infotainment system. A blown fuse can cause intermittent power loss. Refer to your owner's manual for exact fuse locations and ratings.
  • Visual Inspection: Carefully check the wiring harness connecting to the back of the Uconnect screen and the main head unit (if accessible). Look for loose connections, pinched wires, or signs of corrosion.
  • Battery Voltage Check: Use a multimeter to check your vehicle's battery voltage. Low or fluctuating voltage can sometimes cause electrical anomalies, including screen flickering. Ensure the battery is healthy and charging system is operating correctly.
  • Scan for DTCs: While there might not be a specific OBD-II code for screen flickering, a general OBD-II scanner might reveal communication errors (U-codes) or other electrical faults within the vehicle's network that could be indirectly affecting the Uconnect system. For more advanced diagnostics, an OEM-level scan tool can check for specific infotainment module fault codes and perform software updates.

Common causes (most likely first)

Several factors can cause your 2020 Charger Uconnect display to blink on and off:

  • Loose or corroded wiring/connectors: This is a very common culprit. Vibrations over time can loosen connections to the screen or the head unit, leading to intermittent power or data loss.
  • Software glitches: Bugs in the Uconnect software can cause erratic behavior. Outdated software versions are particularly susceptible.
  • Faulty display panel: The screen itself can develop internal faults, leading to flickering or failure.
  • Defective head unit/radio module: The main control module for the infotainment system might be failing, causing inconsistent output to the display.
  • Power supply issues: Problems with the vehicle's electrical system, such as a failing battery, alternator, or a faulty voltage regulator, can lead to insufficient or unstable power to the Uconnect system.
  • Blown fuse: A partially blown or intermittently failing fuse can cause power interruptions.
  • Internal TSBs (Technical Service Bulletins): Chrysler/Dodge may have issued TSBs addressing known issues with the Uconnect system in your specific model year. These often include software updates or specific repair procedures.

Step-by-step diagnosis and fixes

Addressing the flickering Uconnect display in your 2020 Charger requires a methodical approach:

  1. Perform a Uconnect Soft Reset: As described above, hold the volume and tuner knobs for 10-20 seconds. This is the easiest first step.
  2. Inspect Fuses: Check all fuses related to the radio, infotainment, and accessory power. Replace any blown fuses with the correct amperage.
  3. Check Battery and Charging System: Ensure your 12V battery is fully charged and healthy. Test the alternator output to confirm stable voltage.
  4. Inspect Wiring and Connections:
    • Disconnect the negative battery terminal before working on electrical components.
    • Carefully remove trim panels to access the back of the Uconnect screen and the main head unit.
    • Visually inspect all connectors for looseness, corrosion, or damaged pins.
    • Disconnect and reconnect these connectors to ensure a firm fit. Use dielectric grease if corrosion is present.
    • Look for any pinched, frayed, or damaged wires along the harness.
  5. Check for Software Updates: Visit a Dodge dealership or use an OEM-compatible scan tool to check if there are any available software updates for your Uconnect system. Updates often resolve known bugs.
  6. Test Individual Components (Advanced): If the problem persists, a professional might use diagnostic tools to test the display panel and the head unit module independently to determine which component is at fault.
