Consumer Reviews for the GMC Sierra 1500
Read recent reviews for the GMC Sierra 1500
Good but not class leading
Davelv, 07/08/2020
2020 GMC Sierra 1500 Denali 4dr Crew Cab 6.6 ft. SB (5.3L 8cyl 8A)
Just put 8500 miles in 7 weeks on a new 2020 Sierra 1500 Denali with the 3.0 Duramax. Overall mpg was 24 with highway speeds at 75 to 80 mph. Driving at 55 mph in construction zones netted 40 to 50 mpg. Fantastic engine. Ride is smooth. Seats are comfortable. Easy to drive all day. However.... the navigation voice input is useless as it can't recognize most requests. Navigation … also will try to send you down a goat path which might be on the maps but is not a real road. And worse it still has the 2016-2018's occasional problem of saying go right when the direction is really left, and vice-versa. Expect to always have to use Apple Carplay as backup for finding stuff and getting good directions. Also the screen is small and can't adequately display maps and music info at the same time. Tailgate is very heavy, as is its subdoor which is tough to close when the gate is down. Truck came with an electrical cable hanging from underneath that if it had caught on something would have torn it away - but was easily re-positioned to tuck it out of harms way. Heads-up display is nice, but the navigation map doesn't fully translate to it, just arrows and road numbers. Radio when it starts in a garage says no satellite signal message which doesn't go away until the channel is changed in the clear. DEF usage about 1 gallon/1000 miles. The 3.0 Duramax starts quickly and idles at 300 rpm and is almost unnoticeable at stop lights. Definitely suggest getting a start/stop eliminator since otherwise it resets every time the engine starts. Lane keeping is weaker than the 2016-2018 models, and severely lags other manufacturer's capabilities to self-drive for extended periods. Adaptive cruse control uses camera and shuts off when driving into the sun, but the standard cruise can still be used - a radar unit would eliminate this problem. Interior has a lot of plastic on the doors and dash that scratches easily. Sunroof is still only a small single pane instead of dual pane. It is a nice vehicle but would be fantastic with technology upgrades, higher interior quality availability, and some luxury options, e.g. dual pane sunroof, rear window shades, 20 way seats. Note that Model selected was for the 5.3L, not 3.0 Duramax as Edmunds doesn't list it, but this review is for the 3.0 Duramax.
