It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.
 
All involved vehicles that are in dealer inventory must be held and not delivered to customers, dealer traded, or used for demonstration purposes until the repair contained in this bulletin has been performed on the vehicle.

Condition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2011-2012 MY Buick Regal and LaCrosse, 2010-2012 MY Cadillac SRX, 2011-2012 MY Chevrolet Camaro, and 2010-2012 MY Chevrolet Equinox and GMC Terrain vehicles equipped with power height adjustable driver and passenger front seats. Some of these vehicles may have a condition where the bolt that secures the power front seat height adjuster can become loose or fall out. If the bolt falls out, the seat will drop suddenly to the lowest vertical position. The sudden seat movement may affect a driver’s ability to safely operate a vehicle or increase the risk of injury to the seat occupant in a vehicle crash.

Correction
Dealers are to replace the height adjuster shoulder bolt.

Vehicles Involved
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle History screen in GM Global Warranty Management system. Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.

The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall.
