2015 Kia Rio

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 Rio.

Body PASSENGER CARTransmission Automatic (S6)

The 2015 Kia Rio is a passenger car fitted with an Automatic (S6) transmission and EPA-rated fuel economy of 27/36/30 mpg, its engine requiring 3.8 quarts of oil with viscosity grades spanning 5W-20, 10W-30, and 5W-30 API. Within the model’s 2000–2023 production span, this year accumulated 52 owner complaints—far below the 2001 high of 227 yet above the 2000 low of 3—with engine issues representing the primary concern alongside a single recall. This positions the 2015 Rio as a moderately reliable entry that avoids the severe complaint volumes marking the line’s most problematic years.

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 third-generation Kia Rio (2012–2017) shows a clear complaint arc: a sharp spike in 2013 (153 complaints) followed by a retreat to roughly 50–52 complaints in 2014 and 2015, before rising again in 2016 (77) and tapering in 2017 (31). The 2015 model year sits in a relatively stable valley within that arc, with 52 complaints, 1 recall, and 2 investigations — nearly identical to the 2014 figures and well below the 2013 peak. Recalls and investigations remained constant across 2012–2015, suggesting Kia was managing a consistent set of regulatory actions rather than introducing new ones. However, the 2015 complaint profile warrants caution: 10 of its 52 complaints involve fire (roughly 19 percent), alongside 4 crash complaints, with engine-related issues dominating at 17 complaints — the data does not specify root causes for these. TSB counts declined from 133 in 2013 to 100 in 2015, indicating manufacturer service attention was tapering as the generation matured. Overall, 2015 is a reasonable buy within this generation — it avoids the worst of the 2013 spike and the 2016 uptick — but prospective buyers should prioritize a pre-purchase inspection focused on the engine and fire-related risk areas given the elevated fire complaint ratio.
