  General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500, 2500, 3500, and Chevrolet Silverado 1500, 2500, and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator, or the inflator sidewall may rupture.

  SERVICE BRAKES, HYDRAULIC:PEDALS AND LINKAGES

  General Motors LLC (GM) is recalling certain 2015-2016 Chevrolet Silverado 2500, 3500, 1500 Crew Cab Special Service, Tahoe Police Pursuit/Special Service, GMC Sierra 2500, and 3500 vehicles. The brake pedal pivot nut may loosen, causing the brake pedal to be loose or inoperative.

  Risk: If the brake pedal becomes loose or inoperative, the driver may be unable to stop the vehicle by using the brake pedal. Additionally, a loose pedal may also interfere with the accelerator pedal. Either condition may increase the risk of a crash.

  Remedy: GM will notify owners, and dealers will add adhesive to the nut and reinstall the nut with increased tightness, free of charge. The recall began October 3, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 18278.

• Recall 17V664000Oct 19, 201735,292 vehicles
  FUEL SYSTEM, GASOLINE:STORAGE:AUXILLARY TANK

  General Motors LLC (GM) is recalling certain 2011-2015 Chevrolet Silverado 3500 and GMC Sierra 3500 trucks equipped with dual fuel tanks. The low fuel level sensor for the front tank may stick causing the rear tank to overfill the front tank.

  Risk: If the front tank overfills, the excess pressure may cause the front tank to expand and contact the driveshaft, possibly resulting in a hole in the tank. The hole will leak fuel, which in the presence of an ignition source, can increase the risk of a fire.

  Remedy: GM has notified owners, and dealers will replace the rear tank fuel pump or update the fuel-level sensor software, as well as inspect the front tank, replacing it as necessary, free of charge. The recall began December 11, 2017. Owners may contact GM customer service for Chevrolet 1-800-222-1020 or for GMC customer service at 1-800-462-8782. GM's number for this recall is 17399.

  AIR BAGS:FRONTAL · AIR BAGS:FRONTAL:SENSOR/CONTROL MODULE-INACTIVE · SEAT BELTS:PRETENSIONER

  General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

  Risk: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.

  Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. 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. GM's number for this recall is 17287.

  Desiccated Air Bag Inflator Rupture

  From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants.

   I own a 2015 Chevrolet Silverado 3500HD Duramax diesel. At approximately 130,000 miles, the high-pressure CP4 fuel pump failed internally, sending metal shavings throughout the fuel system and contaminating major components. The truck suddenly lost power on the freeway and became inoperable without warning. I was barely able to get out of traffic before it had to be towed to a Chevrolet dealership. This created a serious safety hazard, especially considering the risk if it…

   Truck was operating on the highway at highway speed. Suddenly the truck went into a drastic engine power reduction mode and severe automatic downshifting occurred; the truck came to a complete stop on the highway. Diagnostics proved to be a CP4 injector pump failure sending metal into the fuel system, needing a complete contamination kit and new CP3 pump conversion. This apparently is a known defect in GM vehicles and should have been recalled.
