General Motors dropped a bomb this week when it announced that it was upping its powertrain warranty coverage to 5 years/100,000 miles. That gives the General the best warranty coverage of any full-line automaker, but which company has the best overall warranty coverage and which the worst? Where does your favorite brand fall in the mix? Cars!Cars!Cars! did some digging and compiled a complete list of every automaker's warranty coverage. It's great to see this information compiled in one place, and a little telling, as well. Below are some highlights we found interesting.

Best Overall Warranty Coverage
  • Hyundai (Basic - 5 yr. / 60,000 mi., Drivetrain - 10 yr. / 100,000 mi.)
  • Kia (Basic: 5 yr. / 60,000 mi., Drivetrain: 10 yr. / 100,000 mi.)
  • Mitsubishi (Basic: 5 yr. / 60,000 mi., Drivetrain: 10 yr. / 100,000 mi.)
Worst Overall Warranty Coverage
  • Chrysler (Basic: 3 yr. / 36,000 mi., Drivetrain: 3 yr. / 36,000 mi.)
  • Dodge (Basic: 3 yr. / 36,000 mi., Drivetrain: 3 yr. / 36,000 mi.)
  • Jeep (Basic: 3 yr. / 36,000 mi., Drivetrain: 3 yr. / 36,000 mi.)
Interesting Note: We noticed on a commercial for the Ford Focus that it was being offered with a 5-year / 100,000-mile warranty. Curious, we checked Ford's website and learned that the Focus has been offered with such extensive powertrain coverage since late 2003. It's identical to GM's new warranty save for a $100 deductible. We seem to remember other individual models being offered with extended warranties like this. Can anyone remember others?
