Safety recalls (2)
Exterior Lighting:headlights 2022-03-08 · campaign 22V137000 · 740,581 vehicles
Defect: General Motors, LLC (GM) is recalling certain 2010-2017 GMC Terrain vehicles. A reflection caused by the headlight housings may illuminate areas above the vehicle and outside of the driver's view with excessively bright light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: The bright reflection may cause a glare for other drivers, reducing their visibility and increasing the risk of a crash.
Fix: Dealers will install headlamp appliques, free of charge. Owner notification letters were mailed September 8, 2022. Owners may contact GMC customer service at 1-800-462-8782. GM's number for this recall is N222363740.
Seats:front Assembly:power Adjust 2014-07-23 · campaign 14V447000 · 414,333 vehicles
Defect: General Motors LLC (GM) is recalling certain model year 2011-2012 Buick LaCrosse, Regal and Chevrolet Camaro, as well as certain 2010-2012 Cadillac SRX, Chevrolet Equinox and GMC Terrain vehicles, equipped with power height adjustable driver and passenger seats. In the affected vehicles, the bolt that secures the driver's and passenger's power front seat height adjuster may fall out causing the seat to drop suddenly to the lowest vertical position.
Risk: If the driver's seat unexpectedly drops, the distraction and altered seat position may affect the drivers' control of the vehicle, increasing the risk of a crash.
Fix: GM will notify owners, and dealers will replace the height adjuster shoulder bolts, free of charge. The manufacturer distributed interim letters to owners on September 11, 2014. The recall began on December 26, 2014. Owners may contact GM customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14271.
