Dash crack around passenger airbag which could damage airbag or become shrapnel in an accident. This is my 2nd dash that cracked in the same location.

- Panama City, FL, USA

Around 37,000 miles a crack appeared on the passenger side dash, around the passenger airbag. There are now 3 cracks around the airbag and these cracks could potentially result in a tear in the airbag during deployment, rendering the airbag ineffective in preventing injury during an accident. From online searches, it appears this might have been a design issue on the 2010 model that was fixed starting with the 2011 trucks. The dealer informed me that there is no recall. I feel that due to the possible safety issue associated with this, the dashes for this model year of Sierra should be fixed by GM.

3 years ago while my vehicle was still "under bumper to bumper warranty" a crack on the passenger side dash appeared at the upper left corner of where the plate is that covers the airbag. Munday Chevrolet in spring Texas told me this was not covered under the "warranty" but they would replace it for a reduced cost of $1,000. GM is not getting another bail out from me. The single crack developed a secondary crack resulting in a "Y" shaped crack. About a week ago the area in the "top" of the "Y" fell out so now there is a hole and a crack. The problem is getting worse and not only does this unfairly devalue my investment because GMC used inferior, cheap materials, most importantly it is not safe. If the airbag deploys, there is an increased likelihood that the entire dashboard splinters into sharp deadly projectiles. This company has a history of covering up inferior products and poor decisions resulting in loss of life and financial loss. GM continues to expect customers and taxpayers to suffer for their lack of quality and poor decisions. GM needs to be held accountable and replace dangerous and defective dashboards or they will continue to cut corners and hide issues. Please do not allow GM to exploit hard working families.

I recently purchased a 2010 GMC Sierra crew cab. The rear seat head restraints are inadequately and/or defectively designed, and will offer little protection to the rear seat passengers in the event of a rear end collision. The restraints are mounted on short posts, which do not extend high enough to offer protection to most individuals who are seated in the rear. The posts also do not lock in place, (like the front headrests) and simply slide up and down freely. I contacted GMC by letter, and requested that they modify or replace the headrests, but they refused, stating that the vehicle was designed to pass all federal safety standards. After doing some research, I realized that auto manufacturers are not required to install head restraints on the rear seats of passenger vehicles, and that the shape, size and location of the restraints continues to vary from vehicle to vehicle. It therefore appears that many vehicles, such as mine, offer inadequate head protection for all but the front seat passengers. Indeed, the protection is so poor in the Sierra, that any front or rear collision will likely result in the rear seat passengers' heads colliding with the rear window, causing head trauma in addition to the cervical trauma sustained from the lack of head and neck support. I am quite disappointed that my vehicle offers such inadequate protection, and hope that the NHTSA will take action on the issue. The cost of installing adequate head restraints in all U.S. vehicles surely outweighs the health care and human costs that are being borne by our consumers every time someone is injured due to a manufacturer's faulty or negligent head rest design. Until the NHTSA mandates such protections, auto manufacturers will have free reign to continue to skimp on consumer safety, and the U.S. public will continue to suffer the consequences.
