Hyundai: a 10-year warranty that rebuilt trust
Hyundai's early US cars became a joke for poor quality. In 1998 it offered a 10-year, 100,000-mile powertrain warranty, backed it with real quality improvements, and sales took off.

What happened
Hyundai entered the US in 1986 with the low-priced Excel, selling more than 160,000 in the first year. Quality problems soon damaged its reputation, sales fell, and Hyundai became a punchline on late-night TV.
In 1998 Hyundai introduced ‘America's Best Warranty’: 10 years or 100,000 miles on the powertrain, far beyond competitors. The warranty told buyers Hyundai stood behind its cars. Crucially, Hyundai also invested heavily in quality control so the warranty didn't bankrupt it.
US sales rose from about 90,000 in 1998 to about 400,000 in 2003, and its quality rankings climbed to among the best in the industry.
