0k so would we be covered in this coverage adjustment if we are not the original owners and the truck has barley over 100,000 miles on it? and where can I take it? Thank You your help has helped a great deal!
GM Mechanic: John, GMC Technician replied 8 years ago
Most likely,since there has been an excessive amount of failure with these fuel injectors ,I believe they will cover the replacement of all fuel injectors.I suggest you contact your local GM dealer & speak with the service manager about this.
