General Motors is increasing the Powertrain warranty on all of its 2007 passenger vehicles to five years and 100,000 miles.
The automaker says the increase, from the previous warranty of three years and 36,000 miles, covers 900 engine, transmission and driveline components. The warranties, which have deductibles and are transferable, are accompanied by GM's roadside assistance and courtesy car programs.
The Powertrain warranties will be in addition to the current three-year, 36-thousand-mile bumper-to-bumper guarantees. Buicks, Cadillacs, Hummers and Saabs currently have four-year, 50,000 mile bumper-to-bumper coverage.
The program takes effect today.
Korean automaker Hyundai offers ten-year, 100,000 Powertrain guarantees.
In July, Ford extended its Powertrain warranties by up to two years on its 2007 Ford, Lincoln and Mercury models.
