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 1998 Kia Sportage sits at the peak of the generation’s complaint trend, with 383 complaints and four recalls, compared to 217 in 1997 and a decline to 349 in 1999. Its recall count is slightly higher than the surrounding years, suggesting a modest uptick in safety‑related issues. The top complaint categories—Engine & Engine Cooling (57), Service Brakes, Hydraulic (48), Power Train (42), and Electrical System (26)—indicate a concentration on core mechanical and electrical reliability rather than isolated defects. Crash and fire complaints (19 and 6 respectively) are relatively low, but the overall higher complaint volume implies more frequent owner concerns. Given this context, 1998 represents a year of higher reported issues than its neighbors, so a used 1998 model should be inspected closely for engine, brake, and electrical components before purchase.
