About Hyundai Service at Riley Auto Care
Hyundai has transformed from a budget brand into a genuine competitor in every segment — producing stylish, well-equipped vehicles that earn strong reliability ratings. The Elantra, Sonata, Tucson, Santa Fe, and Palisade are all popular choices for drivers who want modern features and solid value. At Riley Auto Care & Transmissions, we service the full Hyundai lineup and understand the specific maintenance needs that keep these vehicles performing at their best.
One of the most significant issues affecting certain Hyundai models is the Theta II GDI engine, which has a documented history of oil consumption and bearing failure. If you own a Sonata or Santa Fe with the 2.0T or 2.4L four-cylinder engine, we can perform an inspection and advise you on the best course of action. We also service Hyundai's dual-clutch transmissions (DCT), which require specific fluid and adjustment procedures to prevent shudder and hesitation.
Hyundai's hybrid and plug-in hybrid models — including the Ioniq and Tucson Hybrid — require technicians familiar with high-voltage systems and regenerative braking. Our team is experienced with hybrid service and can handle everything from routine maintenance to more complex electrical diagnostics. Serving Hyundai owners throughout the area, we provide the thorough, honest service your vehicle deserves.
