The Chevy Silverado HD and the Sierra HD are both GMC products and these trucks are pretty similar in many ways. The HD means these trucks in the heavy-duty class and designed to be big haulers, allowing you to pull some of the heaviest trailers available.

Consumer Reports tested the two 2020 trucks to see how well they stacked up to each other and to their competitors. For the most part, they liked each one, but there’s still one plaguing problem they both have, that most big pickups like these deal with. But, first, the list of what they liked.

What did Consumer Reports like about the 2020 Silverado HD and the 2020 Sierra HD?

Consumer Reports found four main areas that benefited these two trucks. They liked the power train option with the 6.6-liter turbo diesel V8 engine matched to a 10-speed automatic transmission. The standard engine, though, is a 6.6-liter V8 with a 6-speed automatic. The trailer towing technology pleased them as well, with more than enough features to make hauling even easier.

Interior space was another area that got good marks with them. The trucks came with plenty of room to drive and ride comfortably, and the power driver’s seat was a nice bonus. The controls on the dash weren’t too complicated to use, and the convenient buttons on the back of the steering wheel turned out to be pretty handy when driving. They found these trucks to have ample storage space. There are more than enough available places to store almost any item you can think of.

What problem plagues these two trucks and can it be remedied?

Both the 2020 Silverado HD and the 2020 Sierra HD have great handling, but unfortunately, you can’t say the same of the ride. Many drivers complain that the ride is very stiff and because they’re heavy-duty trucks, it’s expected, to some extent.

They’re huge machines and it’s difficult to fine-tune the suspension to offer a better ride. The front end of the Silverado and Sierra have an independent suspension, which helps to balance out the front wheels when one hits a bump. For the back, the rear suspension comprises the solid axle with leaf springs.

Unfortunately, the cause of the rough ride is a mystery. Some owners, on the GM Truck forums, believe replacing the shocks with compatible aftermarket ones would help. Others believe the leaf springs are the cause and that you should give it time because they tend to break in after a few thousand miles and will run smoother.

Still, some drivers feel you can remedy the roughness by taking a bit of air pressure out of the tires. Instead of 40 lbs a tire, you could try decreasing it to 35 lbs of pressure, which seemed to help some truck owners.

What other issues did the 2020 Silverado HD and the 2020 Sierra HD have?

Besides the rough ride, there were a few other problems they didn’t particularly care for. They felt that the tall hood on these trucks made it difficult to see over the front end to park. You can’t tell where the actual front grille is to know exactly where you can stop in a parking spot without risking a bump to the vehicle in front of you. Practice and planning would benefit this though.

Also, getting in and out of the truck will require some climbing. They’re taller than the lighter-duty pickups, so you can’t just step into one of these. You must get used to making the climb up and the trek down if you go with a heavy-duty truck like these two. The last thing they didn’t like was the price of some of the added features you could get. The turbo diesel engine, for example, costs almost $10,000 more to add to your truck.

The 2020 Silverado HD and the 2020 Sierra HD are great pickups if you need something to haul some heavy loads. Don’t expect to experience a smooth ride with these, though, at least not yet. The future may bring newer technology that could change that. But, for now, because of their size, and the fact that they handle higher towing capacity, a strong suspension is needed to handle it.
