Lens won't focus in manual or auto

My canon 18-55mm IS II lens has recently stopped working after a month. Focus ring will still move in auto but doesnt get close to the image being in focus. When the lens is in manual moving the focus ring does almost nothing at all. If the object is maybe 4 inches away the camera is able to focus onto it but anything further causes problems. I have tried taking picture outside while the sun is high with the same issues.

It sounds as though the focus motor may have gotten jammed. This can happen if you manually rotate the focus ring while the lens is in autofocus mode. Canon's cheaper lenses are not designed to be used that way, and doing so can damage the lens. Sometimes this damage can be corrected and sometimes not. The process is described in two or three threads in the forum and should be followed carefully. It reads like a cure that's worse than the disease, but it has enabled some users to save their lenses.

 

If the prescribed fix doesn't work, you'll probably need a new lens. Repairing a cheap kit lens usually costs more than a replacement would.

 

OTOH, if it's an "STM" lens, it could just be that the camera's battery is weak. STM lenses use electric focusing, even in manual mode, and depend on the camera's battery for power. If it is an STM lens, it should say so on the lens itself.
