This era of Hyundai production suffered from quality control issues that the company has since addressed. Common problems included engine failures, particularly timing belt issues that caused catastrophic damage. Transmission problems were frequent, with rough shifting and premature failure. Electrical system failures and poor crash protection also plagued these vehicles. The 1998 and 2000 models showed similar concerning patterns.

Buyers interested in Sonatas should consider the significantly improved 2006-2010 generation, which showed dramatic quality improvements. Modern Sonatas bear little resemblance to these early models.
