2014~2018 Mazda 3 (2017) – Reverse Camera Blurry or Black Screen, Sensors Not Working in Reverse

[RuiAlessio]

Hi everyone,


I’m experiencing an issue with my Mazda 3 (3rd generation, 2017 facelift) and I’m hoping someone here might have some insight.


Today I noticed that when I shift into reverse, the rear view camera does not work properly. The problem shows up in two different ways:

• Sometimes the camera image is very blurry or unclear, like the photo shows us
• Other times the screen goes completely black

When the screen is black:

• The parking sensors do not activate (no sound, no visual indicators)
• The camera-related menu options become greyed out and cannot be selected

The issue happens specifically when engaging reverse gear. Outside of that, the infotainment system seems to work normally.


I haven’t changed any settings recently and this problem just appeared today.
Has anyone experienced something similar?


Possible causes I’m wondering about:

• Rear camera failure
• Wiring or connection issue (especially at the tailgate)
• Infotainment system (MZD Connect) software or hardware problem
• Reverse gear signal / sensor issue

Any suggestions on what to check first, or how to diagnose this properly, would be greatly appreciated.


Thanks in advance!
