2002 Hyundai XG

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2002 XG.

Body PASSENGER CARTransmission Automatic 5-spd

The 2002 Hyundai XG is a passenger car equipped with a 5-speed automatic transmission, achieving EPA-estimated fuel economy of 16 mpg in the city, 24 mpg on the highway, and 19 mpg combined. This model year accumulated 68 owner complaints across its lifespan, with air bag systems representing the most frequently cited concern, alongside three issued recalls. While any complaint tally indicates areas for potential improvement, the relatively modest number of reported issues positions the 2002 XG as a reasonably dependable offering within Hyundai's model lineup for that period.

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 federal record shows a clear escalation into the 2002 model year. Prior XGs reported only 1 complaint in 2000 and 2 in 2001, with no recalls or investigations either year, while technical service bulletins rose modestly from 23 to 31. In 2002, the four most-reported complaint areas alone—air bags (11), suspension (10), power train (6), and gasoline fuel system (4)—total 31 entries, already far exceeding the prior full-year counts, and the year also registers 9 crash-related and 3 fire-related complaints. No recalls or investigations are listed for 2002, but the data does not explain root causes. This places 2002 at a deterioration point in the generation’s early reliability arc, with safety-critical systems dominating the complaint profile. For a buyer, that makes the 2002 XG a risky choice unless a pre-purchase inspection specifically verifies air-bag, suspension, fuel-system, and power-train condition; on balance, it is not the strongest year to buy.
