2017 MDX Infotainment Screen Flickering/Going Black

Vehicle: 2017 Acura MDX Technology Package

I have a 2017 Acura MDX Technology Package, and the infotainment screen has started acting up. It flickers on and off, sometimes going completely black for several seconds before coming back. It's really annoying, especially when using navigation or the backup camera, as it cuts out at critical moments.

It seems to happen randomly, not necessarily over bumps or in specific weather. Sometimes it's fine for a whole trip, other times it's constant. I've tried restarting the car, but the issue persists. Is this a common problem with the 2017 MDX, and what could be causing it?

ClearTheCode admin answer:

Infotainment screen issues like flickering or going black on your 2017 Acura MDX Technology Package can be frustrating and are often related to electrical connections or the head unit itself. Here are the common culprits:

  1. Loose or Damaged Wiring/Connectors: The most frequent cause is a loose or corroded connection behind the infotainment unit. Over time, vibrations can cause connectors to slightly dislodge, leading to intermittent power or signal loss. A technician would typically remove the dash trim to access and inspect these connections.
  2. Software Glitch: Less common for intermittent flickering, but a software bug within the infotainment system's operating system could cause instability. Check with an Acura dealer if there are any available software updates for your head unit.
  3. Overheating: While less likely to cause flickering, if the head unit is overheating, it might temporarily shut down or reduce functionality. Ensure vents (if any) are not blocked.
  4. Faulty Head Unit: If wiring and software are ruled out, the infotainment head unit itself might be failing. Internal components can degrade, leading to display issues. This is often the most expensive fix.
  5. Power Supply Issue: A fluctuating power supply to the head unit could also cause this. This might stem from a wiring issue or a problem with the vehicle's electrical system, though usually, other electrical components would also show symptoms.

OBD-II Codes: Infotainment issues rarely trigger standard powertrain OBD-II codes. However, a dealership-level scanner can access specific diagnostic codes for the infotainment system (e.g., communication errors).

When to See a Shop: Because this involves disassembling parts of the dashboard and potentially diagnosing complex electrical systems, it's best to have your MDX looked at by an Acura dealership or a specialized automotive electronics shop. They can safely inspect the wiring, check for software updates, and determine if the head unit needs repair or replacement.
