The official notice
Defect
Certain vehicles may fail to conform to Canada Motor Vehicle Safety Standard (CMVSS) 202 - Head Restraints. The optional Universal Tablet Holder accessory may have been incorrectly installed on front seat head restraints, which may prevent the head restraint posts from fully engaging in the seat back. A head restraint that is not fully engaged in the seat back could loosen and dislodge, or inadvertently move to an undesired height which may provide insufficient head and neck support, increasing the risk of injury to the seat occupant in a crash, and would fail to comply with the requirements of the standard.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the head restraints and tablet holders for correct installation and reinstall if necessary. General Motors will also mail corrected installation instructions to customers who purchased the Universal Tablet Holder over the counter for installation on their own vehicles.
