Sierra 1500

Standard equipment on a new 2008 Sierra 1500 crew cab was not on the vehicle. The item being noted as the dic or driver information center is the dashboard computer that show mpg, tire air pressure and other basic information vital to everyday driving, fuel management and safety. Again, this is listed as standard equipment. And it was discovered within the first 100 miles of driving the vehicle that the item was not on this/our particular vehicle. The deletion of this equipment also severely decreases the value (resale or not) of this vehicle.

Rodent problem causing a major gas leak during operation of vehicle, 2008 GMC Sierra 1500. This is the explanation from the service manager at fox Chevy in laurel md. There solution to fix this problem is to replace plastic fitting that was supposedly eaten by a rodent. Which leads to my concern that if this could happen to me once it surely could happen again and with disastrous results. I've been in contact with GMC customer service and I have started a case, file #71-623647784. I want the public to be aware of this because of its hazardous nature. I waiting to hear from GMC"S customer service specialist to see if there is a resolution, such as shielding the gas fitting from possible rodent accessibility.
