Seat belts

NHTSA 17V437000

July 2017

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.

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.

Electrical system

NHTSA 14V317000

June 2014

General Motors LLC (GM) is recalling certain model year 2014 Buick LaCrosse vehicles manufactured April 30, 2013, to September 1, 2013. In the affected vehicles, a wiring splice in the driver's door may corrode and break, resulting in the absence of an audible chime to notify the driver if the door is opened while the key is in the ignition. Additionally, the Retained Accessory Power (RAP) module may stay active for ten minutes allowing the operation of the passenger windows, rear windows, and sunroof. 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 118, "Power-Operated Window, Partition, and Roof Panel Systems."

Remedy: GM will notify owners and dealers will inspect the driver door window motor harness, and replace the electrical splice, as necessary, free of charge. The recall began August 2014. Owners may contact Buick customer service at 1-800-521-7300. General Motors number for this recall is 14235.

The affected vehicles may have had brake rotors intended for the rear of the car accidentally installed on the front.

Owners may contact General Motors customer service at 1-800-521-7300 (Buick) or 1-800-222-1020 (Chevrolet). GM's number for this recall is 14128.
