Here's a brand-by-brand look at the warranties on 2009 models.

Bumper-to-bumper protection includes parts and labor on virtually every component. A powertrain warranty only covers the engine, transmission, differential, drive shaft and transfer case.

A transferable warranty remains in effect if the car is sold or retitled. A nontransferable warranty is available only to the original buyer.
