About Kia Service at Riley Auto Care

Kia has rapidly grown into one of the most respected automotive brands on the market, with vehicles like the Telluride earning top honors for quality and design. Whether you drive a sporty Stinger, a practical Forte, or a family-sized Sorento, Kia builds vehicles with genuine substance — and they deserve service from a shop that takes them seriously. Riley Auto Care & Transmissions services the complete Kia lineup with the expertise each model requires.

Like their Hyundai siblings, certain Kia models equipped with the Theta II GDI engine — particularly the Optima and Sorento — have documented issues with oil consumption and internal engine wear. We can perform thorough inspections and advise you on the best path forward. Kia's dual-clutch transmissions, found in the Forte and other models, also require specific service procedures to maintain smooth, reliable operation.

For Kia's growing lineup of hybrid and electric vehicles — including the Niro Hybrid, Niro EV, and EV6 — we provide the specialized service these advanced powertrains require. From high-voltage system inspections to regenerative brake service, our team is equipped to handle modern Kia technology. Serving Kia drivers throughout the region, we deliver quality repairs and maintenance that protect your investment and keep you on the road.
