2021 Kia Sportage

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 Sportage.

The 2021 Sportage is a model that carries a 5.1‑qt oil capacity and is approved for 5W‑30, 5W‑40 or 5W‑20 viscosity in its engine. It records 46 total owner complaints, with the engine again the most frequent complaint area and only two recalls documented. That figure sits far below the model’s peak of 394 complaints in 2017 but remains above the historic low of four complaints in 2003, indicating a modest improvement in reliability for the 2021 year.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2021 Kia Sportage sits in a period of relatively low complaint activity, with 46 complaints, 2 recalls, and 2 investigations, compared to 156 complaints in 2020 and 182 in 2023. Across the 2020‑2022 window, the recall count remains steady at two for 2021, falling to one in 2022, while the investigation count drops from two to zero. The 2021 model’s top complaint areas—Engine (14), Unknown Or Other (10), Engine & Engine Cooling (3), and Unknown Or Other,Engine (2)—mirror the broader trend of engine‑related issues that peaked in 2017 (394 complaints) and have since subsided. Fire complaints (7) and crash complaints (3) are modest, indicating fewer safety‑related concerns than the 2023 spike in crash complaints (182). Given the decline in both complaints and recalls relative to surrounding years, the 2021 Sportage represents a comparatively reliable choice, making it a solid year to consider for purchase.
