18V340000	24/05/2018	AIR BAGS: AIR BAG/RESTRAINT CONTROL MODULE	General Motors LLC (GM) is recalling certain 2018 GMC Terrain vehicles. The sensing diagnostic module (SDM) that senses a crash and deploys the necessary air bags may not power down correctly when the vehicle is shut off, causing it to be inoperative when the vehicle is restarted.	If the SDM becomes inoperative, it will not detect a crash or command the necessary air bag deployment, increasing the risk of injury in the event of a crash.	GM will notify owners, and dealers will reprogram the SDM with updated software, free of charge. The recall began June 29, 2018. Owners may contact GMC customer service at 1-800-462-8782. GM's number for this recall is 18179.

The rear brake caliper pistons may have an insufficient coating causing gas pockets to form, potentially reducing rear brake performance.	A reduction of braking performance can increase the risk of a crash.	GM will notify owners, and dealers will bleed the vehicle's brake system, free of charge. The recall began October 11, 2018. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.

The high pressure fuel pump may detach from its mounting flange, possibly resulting in the pump damaging the high pressure fuel line.

The start/stop accumulator endcap may have missing bolts.	Missing bolts on the start-stop accumulator endcap could result in a transmission oil leak and may progress to a loss of propulsion, increasing the risk of a crash. A transmission fluid leak in the presence of an ignition source may increase the risk of fire.	GM will notify owners, and dealers will inspect the start-stop transmission accumulator and replace it if any bolts are missing, free of charge. The recall began December 15, 2020.
