Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.

GM faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.

2022 GMC Sierra Preview | GM's 'premium truck' is actually now premium

Pros: Quiet and torque-rich Duramax diesel; big touchscreen on most trims; great trailering tech; versatile MultiPro tailgate Cons: Worse ride than most rivals; AT4X priced like a Raptor but doesn't go like a Raptor The 2022 GMC Sierra 1500 is GM’s upmarket half-ton pickup, with a supposed emphasis placed on interior quality and materials rather than bare-bones durability. Supposedly, at least. In reality, the most recent generation hardly lived up to that promise as it showed few upgrades over its Chevy Silverado sibling, which itself possessed a ho-hum, not-really-trying interior clearly overshadowed by Ram and Ford that at least match it in most other respects. It was particularly noticeable when comparing top trim levels. GMC's supposedly premium entry, and especially the Denali, just didn't cut it. That changes in a huge way for 2022. First, thereÂ’s not just one new and massively improved interior, there are two. The SLE, Elevation and SLT once again share their interior design with the Silverado, but that includes a more visually appealing design, better materials, smarter storage and a significant technology upgrade thanks to the standard 13.4-inch touchscreen running the user-friendly Android Automotive OS. The AT4 and Denali trim levels, including the new AT4X and Denali Ultimate, step things up even further with a different dash design and upgraded interior materials. The Ultimate definitely lives up to its name with a characterful and, yes, premium vibe that stands tall against the best of Ford and Ram. Other welcome updates include the option of Super Cruise on top trim levels and a massively more powerful base turbo four-cylinder engine (it produces more torque than the 5.3-liter V8!). Effectively, the 2022 GMC Sierra is now the truck it shouldÂ’ve been since the beginning of this current generation and definitely worth a look – especially if youÂ’re in the market for a premium truck. Now, a bit of housekeeping. While the massively updated model shown here is officially the 2022 GMC Sierra, thereÂ’s a chance you could come across something called the "2022 Sierra Limited.” That was just last year's truck with the 2022 model year stapled to it. There are many reasons for this, but suffice it to say, if you see a Â’22 Sierra Denali with the ugly robot-face dashboard (below right), youÂ’re looking at a Limited. Also, the availability of Super Cruise and other features have been hampered by supply shortages.
