2023 GMC Sierra 1500 consumer reviews

I own a 2023 GMC Sierra Denali with the 6.2 liter v8. The truck just turned 20k miles and my engine locked up. First GM had Active fuel Management, that was a problem causing engines to fail. Instead of doing away with the faulty system that deactivates cylinders while the truck is cruising, supposedly to get better gas mileage, they doubled down and came of with Dynamic Fuel Management, which deactivates even more cylinders at cruising speeds, causing even more V8 engines to blow at extremely low mileage. My truck has been at Al Piemonte Buick / GMC for almost two months now, waiting for an engine replacement, but guess what, this is happening to Chevy Silverados, Cadillac Escalades and of course GMC Sierras, so the engines are not so readily available! Making payments on a truck that I can’t even drive is very frustrating! My Sierra Denali is under factory warranty, so they say it will be covered, but when is my truck going to be repaired and returned to me! GM knows there is a major problem with both the 6.2 & the 5.3 liter V8’s cause of this DFM system, but they refuse to to do the right by their loyal customers and fix this flawed system. I have been buying GM vehicles since the 1980’s, this might be my last GM truck! Hope GM is listening to the multitude of complaints concerning these motors, the worst being 2019-2024 models. Very disappointing state of affairs!

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

I bought my 2023 gmc sierra truck a couple months brand new/used. I started having problems with the brakes. Took it to the dealership and they said there was nothing wrong with my brakes. I’m still dealing with that annoying noise on my brakes. A month ago my front dash screen went blank. Now today a new truck I can t drive my truck out of my driveway! I had no oil and it sounds like my truck motor is going to blow up. I had a couple months took my truck in the dealership to get my oil changed!!!! Then no oil !

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

I have bought ny first GM product ever. Bought my first truck in 1983. My truck is a 2023 Crew Cab 4x4 with the Duramax 3.0 engine, SLT with the X31 package. Comfortable seats with a commanding view of the road. Rear seat room is impressive. I get nearly 30 MPG on my commute to work, 25-26 overall. Minor gripes Google integration could be better. Wish CarPlay was full screen. More customization of the navigation screen would be better. Wish I could add more apps to the Google integration. Sirius, Fuelly, and Gas Buddy would be great.
