I bought a used Sigma 17-70mm f/2.8-4 DC OS HSM for my Nikon D3300. The lens powers up and otherwise seems to work, but autofocus does not engage when I half-press the shutter. The lens AF/MF switch is set to AF, and the camera display seems to alternate between AF and MF.
This lens has its own focus motor, so it should be compatible with Nikon D3xxx bodies. Other lenses autofocus normally on my D3300, and this Sigma lens autofocuses properly on a Nikon D5000.
Is this likely to be a lens firmware compatibility issue, and what basic checks should I try before sending it in?

The lens has an AF motor, so it should work properly with Nikon's D3xxx series.
Try cleaning the contacts on the lens and body with a clean micro-fiber cloth.
Sometimes turning the camera off, then taking the lens off and then putting back on again can fix these kinds of issues.
You may even want to ensure that you're using the latest firmware version in your DSLR.
Take your camera to a local camera shop to have it checked out.
Do other lenses properly focus? If so, then it's a lens issue.
Does the lens focus properly on a different Nikon body? If so, then it could be a incompatibility issue with your specific model of DSLR with it's specific firmware version.
If none of these suggestion fix your problem, then it's time to send the lens in for repair.

Yes — based on the troubleshooting already done, this points to a lens-side compatibility/firmware issue rather than a D3300 body limitation. The Sigma 17-70mm DC OS HSM has its own AF motor, so it should autofocus on a D3300.
Basic checks worth trying first:
- Clean the electrical contacts on both lens and camera with a clean microfiber cloth.
- Power the camera off, remove and remount the lens.
- Make sure the camera body firmware is up to date.
- Confirm behavior with another lens on the D3300 and this lens on another Nikon body.
In your case, other lenses work on the D3300 and the Sigma focuses on a D5000, which strongly suggests an incompatibility between this copy of the lens firmware and the D3300. Sigma support’s recommendation to update the lens firmware is the most likely fix. If a firmware update does not resolve it, the lens may need service.
