2014 Chevrolet Silverado, 2015 Chevrolet Silverado HD, 2015 Chevrolet Tahoe and 2 other models Recall: Radios in the affected vehicles may become inoperative, and as a result…

The defect

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."

The 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.

The fix — what to do

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.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
