What Owners Say
"The Sirrus/XM radio plays briefly and then stops playing whenever the vehicle is started or I change to AM/FM radio settings. I have to change the channel on the Sirrus/XM radio to get it to start playing again."Anonymous, MI (2020 GMC Sierra 1500 SLT 5.3-L V8)
"every time the truck was started the GPS SD Card acted like it was the very first time the truck had ever been used, and forced me to click a message saying something like "once this SD card is used in this truck, it can never be used again in another vehicle". Then when you shut the engine off and restart the truck, the same message would show back up again. It took two visits to the deal's repair shop, and a week of downtime for them to solve the problem"Anonymous, TX (2020 GMC Sierra 1500 AT4 6.2-L V8)
"Intermittent freezes up especially on sirius. Not caused by location or reception problem"Anonymous, NY (2020 GMC Sierra 1500 SLT 6.2-L V8)
"Crackling noise right off the lot"Anonymous, (2020 GMC Sierra 1500 Denali 5.3-L V8)
