Optimum Warranty

GM Optimum Used Warranties

Buy a Certified Pre-Owned Vehicle from Chevy, Buick or GMC and you're protected from the moment you leave the lot. Why? Because all of our 2006-2011 vehicles come with two auto warranties that combine to provide fantastic coverage: a 12-Month/20,000-Kilometer1 Bumper-to-Bumper Warranty, and a 5-Year/160,000-Kilometer2 Powertrain Limited Warranty.


 3-Month/5,000-Kilometer Bumper-to-Bumper Warranty

Every Certified Pre-Owned Vehicle from Chevy, Buick or GMC comes with an industry-leading 12-Month/20,000-kilometer1 Bumper-to-Bumper Warranty. That's four times better coverage than Chrysler and Ford.

What's Included

Almost every part of our vehicles are covered under the 12-Month/20,000-kilometer1 Bumper-to-Bumper Warranty (excludes normal wear and maintenance items). See below for the list of exclusions.

What's Not Included

  • Tire damage or wear
  • Damage due to bedliners
  • Damage due to accident, misuse or alteration
  • Collision, fire, theft, freezing, vandalism, riot, explosion or objects striking the vehicle
  • Misuse of the vehicle such as driving over curbs, overloading, racing or other competition. (Proper vehicle use is discussed in the owner manual.)
  • Alteration or modification to the vehicle, including the body, chassis or components, after final assembly by Chevy, Buick or GMC.
  • Coverages do not apply if the odometer has been disconnected, its reading has been altered, or mileage cannot be determined.
  • Damage or corrosion due to environment, chemical treatments, and/or aftermarket products
  • Damage due to insufficient or improper maintenance
  • Damage due to contaminated or poor-quality fuel


Important: This warranty is void on vehicles currently or previously titled as salvaged, scrapped, junked or totaled.


5-Year/160,000-Kilometer Powertrain Limited Warranty

Every Certified Pre-Owned Vehicle from Chevy, Buick or GMC comes with a transferable 5-Year/160,000-Kilometer2 Powertrain Limited Warranty, plus roadside assistance and courtesy transportation. We believe in our vehicles and aren't afraid to stand behind them. When we say "No worries," we mean it.

  • $0 Deductible
  • Transferable to subsequent owners
  • Roadside Assistance
  • Courtesy Transportation

What's Included

       Roadside Assistance
