Mercedes-Benz GLB

Mercedes-Benz’s boxy-looking GLB compact luxury SUV slots between the smaller GLA and larger GLC. It has very good visibility, generous passenger and cargo room, and is easy to get in and out of. In our tests we found it to be quick, nimble, and fuel efficient. By eschewing the heavily-tapered styling found on many of its newer models, Mercedes has built a useful compact luxury SUV—a rare find.

Reliability

We expect the 2022 GLB to be less reliable than other new cars. This prediction is based on Mercedes-Benz's brand history and similar models in its class.

Predicted Reliability

No Detailed Data Available

Consumer Reports obtains its reliability data from a questionnaire that is sent to subscribers. In the questionnaire, we ask subscribers to note any problems with their cars that occurred in the past 12 months. They are asked to identify problems that they considered serious (because of cost, failure, safety, or downtime).

A typical model has about 200 to 400 samples for each model year. For some model years, typically those of older or less popular cars, we do not have a large enough sample size to provide results of statistical confidence.

There are several ways in which a savvy car buyer can still research the quality of a car.

For this Rating, we averaged a model’s Overall Reliability for the newest three years, provided the vehicle did not change significantly in that time and hasn’t been redesigned for 2021. We include a prediction for a model that is new or has been redesigned, based on its reliability history or the manufacturer’s track record.
