Reliability & federal safety record

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

Federal data for the 2001 Hyundai XG shows minimal activity across the two-year span provided. Complaints rose from one in 2000 to two in 2001, while technical service bulletins increased from 23 to 31; recalls and investigations held steady at zero for both years. The 2001 model sits at the higher end of this brief arc yet still records only one complaint each for engine and cooling/air bag concerns and service brakes/hydraulic issues, with the data not specifying root causes. Crash and fire complaints are absent for the target year. Given the extremely low complaint volume, absence of recalls or investigations, and zero crash or fire incidents in the federal record, 2001 represents the more documented but still low-risk year of this dataset and is a reasonable candidate for a used purchase contingent on an independent pre-buy inspection.
