Among the better years
The 1991 Hyundai Sonata is among the quieter years of the Sonata on NHTSA's books: 41 complaints (80% below the model's median year), a single recall, and no open investigations.
No single system dominates the record — complaints spread across seat belts (9), engine (8), and electrical system (7), which usually points to general build quality rather than one defect.

Remedy
DEALERS WILL LUBRICATE THE TRACK ASSEMBLY AND, IF ANY SYSTEMS ARE FOUND INOPERATIVE, THE SYSTEM WILL BE REPAIRED OR REPLACED, AS REQUIRED.
