Hello,

I am new person to this site, and wanted to reach out to see if anyone might know the best number to call to contact GM Headquarters?
The 800 number is the right people I would like to speak too. And the Main office line online is not correct.
Just wanted to share a great story with them.

Thank you for your help!

 

All else fails check with one of the local GM brands dealerships.

 

This is probably the best way. There is no phone number, but a forum you can fill and send them.
