These are issues documented for the Mercedes-Benz GLA in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

Driver's Door Lock Micro-Switch Corrosion Causing Auto-Park Failure
Electrical / Safety System · severity: Safety-critical - a failed micro-switch can prevent the electronic parking brake's Auto-Park feature from engaging when the driver exits, creating a real, documented unintended vehicle-rollaway hazard. · confidence: 55/100 · 2 cited sources
ⓘ Not yet individually classified
Symptoms to watch for
Electronic parking brake / Auto-Park feature fails to engage automatically after the driver opens the door and exits, even though the vehicle is in Park
In the underlying failure mode, the vehicle may not register that the driver's door has been opened at all
No dashboard warning is guaranteed to precede the failure - this is a silent electrical defect, not one that reliably announces itself first
What To Check
Not detectable on a normal test drive - this is a corrosion-driven electrical defect with no guaranteed precursor symptom, and a test drive does not exercise the specific door-open/exit/Auto-Park sequence the defect affects in a way that reliably reveals it. A VIN-based recall status check with Mercedes-Benz (US or SA, as applicable) is the only reliable way to confirm whether a specific vehicle is affected and whether the remedy has been performed.
This is everything documented for this issue - no repair-cost estimate or TSB/recall reference was found for it, so there's nothing further behind a full report for this specific finding.
