The Git plugin supports specifying additional refspecs to fetch when checking out a commit to build (added as an Additional Behaviour on the branch SCM source).
This configuration is inherited by the Gerrit Code Review plugin, and works when building branches and tags, but is not applied when building Change commits.
This means that any pipeline stages requiring access to other refspecs will fail, unless git fetch is called manually first. For example, SonarQube's Pull Request analysis cannot diff the Change commit against the target branch, so "new code" detection is not available.
A 'good' build, triggered by new commits on the master branch, logs during checkout:
[Pipeline] { (Declarative: Checkout SCM)
[Pipeline] checkout (hide)

And the same snippet, from an open Change in Gerrit:

The key missing line is:
