2024 Mercedes-Benz Glc 300 problems

Verdict · NHTSA data

Worth extra scrutiny

The 2024 Mercedes-Benz Glc 300 is a recall-heavy year with an otherwise ordinary complaint record: 7 NHTSA recall campaigns apply, yet its 33 owner complaints run below the Glc 300 median. The recalls matter more than the complaint count here — verify every campaign was completed before buying.

No single system dominates the record — complaints spread across engine (7), electrical system (6), and transmission (5), which usually points to general build quality rather than one defect.
