The Ram 1500 excels in ride comfort and interior quality. The Tundra is known for its reliability but lacks modern features. The Sierra 1500 distinguishes itself with its MultiPro tailgate and available carbon-fiber bed.
In terms of performance, the Sierra's engine options are competitive, though the F-150 offers more variety. Feature-wise, the Ram 1500 often surpasses the Sierra in interior luxury. Reliability is a mixed bag, with the Tundra generally considered more reliable and the Sierra facing potential transmission and oil consumption issues. Price-wise, the Sierra is typically comparable to the F-150 and Ram 1500.
Alternatives include the Ford F-150 for its wide range of engines and the Ram 1500 for its comfortable ride and luxurious interior. If reliability is a top priority, the Toyota Tundra should also be considered despite its outdated design.

Final Verdict: Is the 2020 GMC Sierra 1500 a Good Truck?
The 2020 GMC Sierra 1500 is ideal for buyers who value a blend of capability and style, and appreciate innovative features like the MultiPro tailgate. It's worth buying if you prioritize design and certain available technologies. Consider buying used to save money, but thoroughly inspect the vehicle for potential transmission or oil consumption issues. The SLT or AT4 trims offer a good balance of features and value. The Denali is suitable for those seeking a more luxurious experience. Carefully weigh the pros and cons against competitors before making a decision.

Great truck!I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Short turn radiusI purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great TruckI did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Currently in Litigation with GMCThis truck has been a nightmare! Its a beautiful truck but everything that could go wrong with the truck has. It has been in and out of the dealership 6 times now. First for the recall issues - excess glue problem on battery and seat belt positioner. Next, came the check engine lights at 7k miles which had to do with braking system. Then, at 30K more CELs which they attributed to needing system updates for emission systems. Truck also had oil pan leak, transmission cooler line leaks, and rear pinon seal leaks fixed at the same time. The CELs came back on shortly after repair. Finally, they found damage on 4 locations to the main engine wiring harness due to rubbing. They fixed that but damaged the steering column so it made a grinding noise on the wheel and was loose. Had them fix that which only worked temporarily. CELs came back on the vehicle. Truck finally died and left me stranded this past weekend due to a failing Diesel Pump and Transmission Cooling Regulator Valve. Finally, The rear window leaks from the factory but due to the amount of miles I have GMC refuses to fix it and wants 4.5K to fix the window and electronics it damaged. I have left multiple messages to my GMC case specialist only to be ignored but when I call GMC customer care they just transfer me back to them. Horrible customer service and an even worst truck.

Best truck I’ve boughtThe features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

I absolutely LOVE my truck!We bought this truck in July of 2020 and it is my “Mama-mobileâ€! Yes it’s a woman’s truck 😉 I have a 7 1/2 year old son and almost 5 year old son, both who are extremely tall for their ages and there is PLENTY of room in the back with room to spare!!! I have put 15k miles on it already and it’s still drives so smooth and I have not had a lick of trouble out of it!! No regrets on this purchase at all, and I’m usually very critical of vehicles!

Pretty Bummed OutHopefully all will get resolved...coming out of a Tahoe with 110,000 miles and excited to get into my 2020 Sierra Denali 1500 Carbon Pro with the Duramax Diesel. At this point, I have had the car 2 weeks and it has been back at the deal twice, this time going on 4 days. First issue was a coolant sensor that set off an engine warning and the second problem is car wouldn’t start due to dead battery. Apparently 4 open recalls on the 2020 and I guess my dealer didn’t take care of them? They still can’t figure out what is draining the battery. Truck has about 900 miles on it. Now have the feeling of “what’s going to be messed up?†Every time I press the start button. Certainly takes the enjoyment out of owning this physically beautiful truck. When it works it is an absolute joy to drive and it is the best looking truck on the road....all that said....I want it gone.
