Does the 2017 Mercedes-Benz GLA have engine problems?

Owner complaints say yes, as a model-year pattern. 14 of 30 relevant complaints filed with NHTSA about the 2017 Mercedes-Benz GLA concern the engine, transmission or fuel system (47%), and the largest group is filed under engine (9). For comparison, the 2016 scores 52% and the 2018 scores 48%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

That depends on the car in front of you, not just the model year.
