What Owners Say
"Fog lamps went out, very hard to replace. Must remove front bumper"Anonymous, TX (2018 GMC Sierra 2500HD Denali 6.6-L V8 diesel)
"Turn indicator light bulb burned out"Anonymous, (2018 GMC Sierra 2500HD SLT 6.6-L V8 diesel)
"The light sensing system reverts to night time driving if you are in a shaded area and it takes way to long when in the sunlight for the gauges and nav system to return to normal. It takes 20 or more seconds if you return to full sunlight."Daniel M., CA (2018 GMC Sierra 2500HD Denali 6.6-L V8 diesel)
"The light that illuminates the climate control buttons would turn off intermittently. When I took it to the dealer, it worked perfectly. However, most of the time the button is not lit."Anonymous, CA (2018 GMC Sierra 2500HD Denali 6.6-L V8 diesel)
