2019 GMC Sierra Denali and its nifty tailgate roll into dealers

We've got more details about the 2019 GMC Sierra Denali now that it's rolling into dealerships, starting with its floor price of $56,195, including destination fee, for the rear-wheel-drive models. That's a jump of $1,900 over the previous generation of its premium full-size pickup. Four-wheel-drive models start at $60,295. The crew-cab truck has grown in every dimension as well, adding about 4 inches to the wheelbase, nearly 2 inches in length and 1.2 inches in width. There's also nearly 3 inches more rear legroom. Bed options are 5-foot-8 or 6-foot-6. There are three engine options. Two are carryovers from 2018: a 5.3-liter V8 that sends 355 horsepower and 383 pound-feet of torque through an eight-speed automatic transmission, and an available 6.2-liter V8 that makes 420 hp and 460 lb-ft of torque and mated to a 10-speed automatic. Both come with GM's dynamic fuel management cylinder-deactivation technology to optimize power and fuel efficiency. A new 3.0-liter turbodiesel paired with a 10-speed automatic is expected in early 2019. The EPA hasn't yet released official fuel economy ratings, but GM estimates them at 17 miles per gallon in the city and 23 mpg on the highway for the two-wheel-drive versions, and 15/21 in four-wheel drive. The truck gets adaptive ride control which can adjust the dampers every 2 milliseconds based on real-time monitoring of the road and driver inputs for improved ride and handling. A new traction select system adjusts the transmission shift points, throttle mapping and StabiliTrak to tailor performance to different terrain or weather conditions. Inside the crew cab, there's new Forge leather-appointed seats, open-pore wood trim and dark finished aluminum decor, plus an 8-inch-diagonal HD color touchscreen with embedded navigation and Apple CarPlay and Android Auto compatibility. Most of the other new stuff we've covered before, including new C-shaped LED headlights and LED tail and fog lamps, optional 22-inch wheels, full-color head-up display, trailer-hitch assist apps and cameras, and rear-camera mirror. The truck also loses up to 360 pounds from the outgoing model via a scratch- and dent-resistant carbon-fiber bed box that replaces steel, and use of aluminum in the doors, hood and tailgate.

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.
