What owners say

Real owners of this exact model-year, shown separately from the NHTSA score. If they disagree, that’s worth knowing.

The fine print: this verdict is computed from public NHTSA complaint and recall records for the 2023 Mercedes-benz Gls-class as a model, not for any individual car. A well-maintained example of an “Avoid” can outlast a neglected “Buy”. Informational only, so always get a professional pre-purchase inspection.
