Chevrolet offered various warranty options in 2007, including a basic bumper-to-bumper warranty and a powertrain warranty (which covers the drivetrain). The powertrain warranty was likely for a longer duration than the bumper-to-bumper warranty, but the exact length (in years or miles) varied and likely expired years ago.
To know the specifics of the original drivetrain warranty on a particular 2007 Impala, you would need to:
* Check the original warranty documents: The best source would be any paperwork that came with the car when it was new.
* Contact a Chevrolet dealership: Provide the VIN number to a Chevrolet dealership; they may be able to access information about the original warranty coverage.
Keep in mind that any original warranty on a 2007 vehicle would almost certainly have expired.
