What Problems Does the 2015 GMC Sierra 3500HD Have?
Frequently reported problems for the 2015 GMC Sierra 3500HD include issues with the diesel exhaust fluid (DEF) system on diesel models, sometimes leading to sensor failures or reduced engine power. Some owners have reported glitches in the infotainment system, such as freezing or unresponsive touchscreens. There have also been reports of occasional transmission issues, particularly with harsh shifting or delayed engagement.
Recalls for the 2015 Sierra 3500HD have addressed concerns such as potential steering shaft separation (affecting a limited number of vehicles) and issues with the brake vacuum pump. It's crucial to check the vehicle's VIN for any outstanding recalls before purchase. Long-term reliability concerns generally revolve around the longevity of the diesel engine's emissions control systems, which can be costly to repair. Rust, especially in areas with road salt, can also be a factor affecting long-term durability. Early model year 2015 trucks seem to have more frequent reports of infotainment glitches than later production models. As with any vehicle, regular maintenance is key to mitigating potential problems.
