Kohler warranty for generators & engines
The short version
Kohler doesn't cover everything, but keeps whole generator covered to 5 years. That full coverage is shorter than most of the 12 brands we compared, which typically cover 1 year in full. You don't need to register to get this coverage.
From Kohler's published warranty, checked October 2026.
