GM Announces 100,000 mile/5-Year Powertrain Warranty

The warranty wars are heating up. Two months after Ford amplified its powertrain warranty to five years or 60,000 miles, GM announced today that it would extend its own powertrain warranty to five years or 100,000 miles across its entire line of 2007 models. That includes Cadillac, Hummer, Saab, Chevrolet, Pontiac, GMC and Buick, and is retroactive for anyone who has already purchased a 2007 vehicle.

Powertrain warranties cover the engine, transmission, transfer case and drive assemblies. GM’s bumper-to-bumper limited warranty remains unchanged. The news will be heralded in a new series of commercials kicking off during tomorrow night’s NFL season opening game. The commercials feature drivers stuck in traffic, with those in GM vehicles magically floating and passing all those stuck in the gridlock below. We’re not sure about flying cars, but any increase in warranty length is a good thing for consumers.
