To find the precise details of your specific vehicle's warranty:
1. Check your owner's manual: This is the best source of information. The manual should clearly state the original warranty terms and conditions.
2. Contact a GMC dealership: Provide them with your vehicle identification number (VIN). They can access the vehicle's history and tell you what warranty coverage, if any, remains.
3. Review any extended warranty documents: If you purchased an extended warranty, the terms and conditions of that warranty will dictate its coverage.
Keep in mind that the original powertrain warranty likely expired years ago for a 2010 vehicle. Any coverage remaining would be from an extended warranty.
