2015 GMC Sierra 2500HD Reliability - Consumer Reports
The Sierra HD and its twin the Chevrolet Silverado HD are designed for heavy towing and hauling. The 6.0-liter V8 and 6.6-liter turbodiesel are both mated to a six-speed automatic. The latter works well, and employs a heavy-duty Allison-made transmission. We measured 14 mpg overall with the diesel. The LTZ trim has a luxurious cabin but ascending to into it is quite a climb.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for over 300,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2021 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

After market lights are between $500 and $800."

ELECTRICAL SYSTEM, SEAT BELTS
Jun 06, 2014
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.
Summary:
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."
What should you 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.

What should you do:
GM will notify owners, and dealers will inspect the fuse block to verify that it is properly secured, repairing it as necessary, free of charge. The recall began on July 30, 2014.
