How Do I Cancel My GM Extended Warranty?

by Leonardo R. Grabkowski

The GM Extended Warranty, officially known as the GM Protection Plan, can be canceled anytime prior to the expiration date. If you cancel within the first 60 days, you are eligible for a full refund of the warranty. After the 60-day period, the warranty refund is pro-rated, meaning that you'll get a portion of your money back depending on how much of the warranty term and mileage allotment is remaining.

Step 1

Find your GM Extended Warranty contract. The contract should have been provided to your by the dealer at the time of sale. The contract has your customer number on it. If you cannot locate it, the warranty representative should still be able to help you cancel your warranty.

Step 2

Read your current odometer display to determine the vehicle mileage. Write the figure down. The amount of your refund depends upon the length of time remaining and the mileage allowance remaining.

Step 3

Contact the GM Extended Warranty cancellation line by calling 1-800-631-5590. Wait to speak with an associate. Tell the associate you wish to cancel your GM Extended Warranty. The associate will request information from you, including but not limited to your customer number and current mileage. The associate may also need your name, address or other personal information. Once the associate has the information, he can look up your account and tell you the amount of your refund.

Step 4

Determine if you want to cancel your warranty based on the pro-rated refund amount. If you wish to cancel, continue with the process over the phone. If not, tell the associate you appreciate his help and hang up.
