GMC SIERRA

ELECTRICAL SYSTEM:SOFTWARE

Genera Motors LLC (GM) is recalling certain model year 2016 Chevrolet Camaro, Malibu, Silverado and GMC Sierra vehicles. The radio may intermittently fail to provide an audio warning when the key has been left in the ignition and the door is opened or when the driver does not fasten their seat belt. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standards (FMVSS) number 114, "Theft Protection", and/or 208, "Occupant Crash Protection."

Risk: An unbelted driver is at a greater risk of injury in a crash.

AIR BAGS:FRONTAL:SENSOR/CONTROL MODULE-INACTIVE

General Motors LLC (GM) is recalling certain model year 2016 Chevrolet Silverado and GMC Sierra pick up trucks manufactured October 13, 2015, to October 14, 2015. In the affected vehicles, the mounting stud used to secure the air bag sensing and diagnostic Module (SDM) may be incorrectly positioned, and as a result, the SDM housing could fracture.

Risk: If the SDM housing fractures, water may get into SDM causing it to malfunction and hinder the proper deployment of the air bags in the event of a crash, thereby increasing the risk of occupant injury.

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.

SEATS

General Motors LLC (GM) is recalling certain model year 2013-2014 Buick Encore and Cadillac ATS; 2014 Cadillac CTS, ELR, Chevrolet Caprice and SS vehicles; and 2014-2015 Chevrolet Silverado and GMC Sierra Trucks. Due to an incomplete weld on the seat hook bracket assembly, the front seats in the affected vehicles may not stay secured in place during a high load condition such as a crash.

Risk: A seat that does not stay secured increases the risk of occupant injury in a vehicle crash.

POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE)

General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado and GMC Sierra vehicles, and model year 2015 GMC Yukon and Chevrolet Suburban and Tahoe vehicles. In the affected vehicles, an electrical signal short may cause the transfer case to shift to neutral without the driver's input.

Risk: If the transfer case switches to neutral while the vehicle is parked and the parking brake is not in use, the vehicle may roll away increasing the risk of injury to bystanders. If the transfer case switches to neutral while the vehicle is being driven, the vehicle would lose drive power, increasing the risk of a crash.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL

General Motors LLC (GM) is recalling certain model year 2014 Chevrolet Silverado vehicles manufactured May 15, 2013, to January 29, 2014, and GMC Sierra vehicles manufactured September 19, 2013, to February 8, 2014, and equipped with both optional accessory all-weather floor mats (option RPO VAV) and optional vinyl flooring (option RPO BG9). The affected vehicles built with the vinyl flooring option do not have the retention features necessary to properly secure the floor mat on the driver's side.

Risk: The floor mat could shift such that it could interfere with the accelerator pedal, preventing its return to an idle position, which could result in unintended vehicle speeds, increasing the risk of a crash.

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.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

General Motors is recalling certain 2014 model year Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles, and 2015 model year Cadillac Escalade and Escalade ESV; Chevrolet Silverado HD; and GMC Sierra HD, Yukon, and Yukon XL, equipped with a 4.3L engine or 5.3L engine.
