GMC SIerra Denali is ready to live the high life

Between the information for the 2014 Chevrolet Silverado High Country and the accidently leaked picture on GMC's consumer site, it didn't take much imagination to envision what the 2014 GMC Sierra Denali would be like. But here it is. Going on sale this fall, the 2014 Sierra Denali will continue to be the most luxurious pickup truck in the General Motors portfolio, while getting more power and technology than ever before.
Like previous models, the 2014 Sierra Denali stands out from lower Sierra models with a big cheese-grater chrome grille, 20-inch chrome wheels and body-color bumpers. Inside, the Denali gets plenty of leather with contrasting stitching, but this is where GMC really steps up from the Silverado High Country with real aluminum trim and a new customizable eight-inch driver display in the gauge cluster. Standard features will include heated and cooled front bucket seats, the Intellilink infotainment system with Bose audio, while the options list offers a Driver Alert Package (with forward collision alert and lane departure warning), a rear-seat entertainment system and a Z71 Off-Road Package.
As for power, the standard engine will be the 5.3-liter EcoTec3 V8 with its 355 horsepower, and the optional engine will be the new 6.2-liter V8. Although official power figures for the bigger engine aren't in yet, GM is finally putting some estimates on paper expecting around 420 horsepower and 450 pound-feet of torque to go with a 12,000-pound towing capacity. The new Sierra Denali will be available in either two- or four-wheel drive. Scroll down for more details listed in the official press release.

2020 GMC Sierra Heavy Duty teased, and you better believe there's a huge grille

Chevrolet has shown us a few photos of its redesigned Silverado Heavy Duty, and today we score our first teaser of the GMC Sierra version of this truck. The most controversial feature of the Silverado HD has to be its massive grille, and the Sierra appears to be no different. Just from this photo of the face, we can already tell it's going to be as bold, some might say gaudy, as the Chevy. We'll have to wait awhile to see it all, though, as GM says the Sierra HD will be making its debut in the second half of 2019. It's no Supra teaser campaign, but this one is already starting out pretty early for a work pickup truck. As far as features and technical details go, mum is the word for now. However, we can assume the Sierra will be nearly identical with the Silverado HD powertrain-wise. We know two engines will be offered on that truck, one being a gasoline V8 and the other a Duramax turbodiesel V8 — the former will be mated to a six-speed automatic, while the latter gets the 10-speed auto. Even though it isn't out yet, the torque figure is already less than the Ram and Ford heavy duty trucks at 910 pound-feet from the diesel. The Ram Heavy Duty just revealed at the Detroit Auto Show scores a whopping 1,000 pound-feet of twist in the torque department. We'll know more about the Sierra HD when the Silverado HD presumably gets revealed with full details at the 2019 Chicago Auto Show at the beginning of February. One thing's for sure: If you want chrome and lots of it, you're gonna get it with the 2020 GMC Sierra HD. 2020 Chevy Silverado HD View 5 Photos Related video: This content is hosted by a third party.

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.
