3 years ago I bought a Nikon d3400, it came with an AF-P 18-55mm lens, and an AF-S 55-200mm lens. Three years, no bugs, no problems.
Today I was hiking up to a waterfall, taking photos. Get to the top, take one photo, then the camera stops taking pictures.
I played around with it, and it seems it won't take a picture at all when in autofocus. When I switch it to manual it takes a photo, but it is blurry, and I can not adjust the focus. I can also hear a clicking and grinding when I rotate the lens between the 35 and 24 mm marks.
The 55-200mm lens works just fine, so I'm fairly certain it's not the camera body.
(Also, if I rotate the lens and focus ring together while half pressing the shutter, it takes a blurry photo in auto.)

Can someone please help me? 😁

It seems like either dirty contacts or something broken in the lens. Try cleaning the contacts with a good contact cleaner, such as DeOxit. Try to get one that is formulated for plated contacts. If that doesn't work, getting a new normal zoom is probably cheaper than having your basic kit lens repaired.

 

The lack of manual focus when the electrics don't work is a major drawback of the AF-P lenses. As long as things work, they are better than the AF-S equivalents, but there is no backup system if things go wrong.

Thanks man, I'll try that.
Do you generally use the af-p or af-s? I might have to go lens hunting soon
