The front camera on my 2016 Murano Platinum was cracked from a stone hit, so the view was very fuzzy. I searched online for a replacement and had sticker shock at the prices I found - $260 to $290 - on sale - plus tax, shipping, etc. I kept looking and found one with the exact same part # 284F14BA0A - on Amazon for $53.23 + sales tax. I have Amazon Prime, so shipping was no charge. It arrived in 2 days, installation took me about 45 minutes due to removal of several push-pin retainers on the grille cover under the hood. The round chrome NISAN emblem pops off - by carefully prying with a plastic trim tool. I replaced all the push-pin retainers, as they are available cheap on eBay: 50 x Bumper Splash Shield Hood Engine Push Clip Screw Rivet for Nissan Infiniti 715668952430 | eBa
This is the link for the new camera at Amazon. It says it is for a Rogue, but is an exact fit for 3rd Gen Murano - and probably other models:

I think the front camera is the same on 2015 - 2018, not sure newer than that. You should find the camera part number by just popping the NISAN emblem off first, then order a new one if yours is cracked/broken like mine below:

Hope this helps!
