  ELECTRICAL SYSTEM:IGNITION

  General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado and GMC Sierra trucks manufactured January 24, 2014, to February 26, 2014, 2015 Chevrolet Suburban vehicles manufactured February 12, 2014 and Chevrolet Tahoe vehicles manufactured February 6, 2014, to February 13, 2014. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.

  Risk: If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.

  Remedy: GM will notify owners, and dealers will replace the ignition lock housing, free of charge. The recall began on November 20, 2015. 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 15573.

  ELECTRICAL SYSTEM:SOFTWARE · SEAT BELTS:FRONT:WARNING LIGHT/DEVICES

  General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado and GMC Sierra, and 2015 Chevrolet Tahoe and Suburban vehicles equipped with a base radio and an internal amplifier. The radios in the affected vehicles may become inoperative, and as a result, there would be no audible chime to notify the driver if the door is opened with the key in the ignition or no audible seat belt warning indicating the seat belts were not buckled. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 114, "Theft Protection and Rollaway Prevention," and 208, "Occupant Crash Protection."

  Risk: Without an audible indicator, the driver may not be aware that the driver's door is open while the key is in the ignition, increasing the risk of a vehicle rollaway. Additionally, there would be no reminder that the driver's or front seat passenger's seat belt is not buckled, which could increase the risk of injury in a crash.

  Remedy: GM will notify owners, and dealers will update the radio software, free of charge. The recall began on July 2, 2014. Chevrolet owners may contact GM's customer service at 1-800-222-1020. GMC owners may contact GM's customer service at 1-800-462-8782. GM's number for this recall is 14315.

    The 2015 Chevrolet Tahoe seems to be known for thermostat failure. My thermostat gauge while driving would drop from 210 to 160 and stay pinned on 160 and the fans would turn on.
