2003 Mercury MARQUIS problems
Verdict · NHTSA data
One of the years to avoid
With 42 complaints filed to NHTSA — about 3.4 times the median MARQUIS year — the 2003 model ranks #3 of 28 MARQUIS years for complaint volume. It lands on the years-to-avoid list.
No single system dominates the record — complaints spread across lighting (8), speed control (5), and electrical system (4), which usually points to general build quality rather than one defect.
