Kia Repair & Service
in Marietta, GA

Kia’s growth in the Marietta market parallels Hyundai’s — Forte, Optima, Sorento, Sportage, Telluride, and Soul are common across the area. Kia and Hyundai share most platforms and powertrains, which means most of what applies to Hyundai applies to Kia, including the Theta II GDI engine recall and warranty extension on 2.0L and 2.4L models from roughly 2011-2019. The good news for Marietta Kia owners is that the warranty coverage is real and meaningful — but only if the shop verifying it knows where to look and how to navigate the claim process.

In Marietta specifically, the Kia models we see most often are the Sorento (LX, EX, SX trims), the Sportage (LX, EX), and the Soul. The 2.4L GDI in 2011-2019 Sorento and Sportage shares the Theta II rod-bearing failure pattern with the Hyundai siblings. The 1.6L turbo on the Soul X-Line and certain Forte trims is a newer platform with emerging patterns. The Telluride (2020+) and Sorento Hybrid (2021+) use newer Smartstream architecture that doesn’t share the Theta II issues. The 2.0L turbo on Stinger and Optima/K5 (later years) is a high-performance variant with its own service considerations.

At Advantage Auto Service in Marietta, we treat Kia and Hyundai as the same diagnostic platform when they share components — because they do. We know the recall status, can verify warranty coverage, perform the KSDS software updates that activate Theta II warranty extensions, and handle the broader service schedule on the shared platforms with the same approach as the equivalent Hyundai. We use OEM or quality aftermarket parts and explain what we find. If you own an affected Kia and are facing repair decisions, talk to us first — the warranty extension may apply even if you bought the vehicle used.
