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.

GM intends to offer semi-autonomous vehicles by 2020

Prepare for a few years of technological saber-rattling, as the world's automakers begin pushing to bring self-driving cars to market. Earlier this week, Nissan announced that it aims to offer autonomous vehicles by 2020, while Google, BMW and several other marks are working on similar efforts.
General Motors is doing things differently, though. Rather than push for a fully autonomous car, it's continuing to refine its semi-autonomous Super Cruise, a product that we tested in April 2012 and that will eventually see use on some Cadillacs before trickling down to the rest of the General Motors family. Super Cruise, which is undergoing testing in the Cadillac SRX, doesn't take complete control out of the driver's hands. Rather, under a very specific set of circumstances on the freeway, it will marry the capabilities of things like lane departure warning and adaptive cruise control to allow the driver to take their hands off the wheel. All of which sounds a lot like the system Mercedes-Benz is launching on the 2014 S-Class.
The system is still in development, according to John Capp, GM's director of electrical controls and active safety technology. Now that that the biggest hurdle, steering control, has been cleared, GM's engineers can focus on things like teaching the system to adapt to differing road conditions and visibility levels. As we reported in 2012, Super Cruise is still befuddled in low-visibility situations or when road markings aren't particularly clear.

GM will expand Super Cruise to entire U.S. lineup after 2020

General Motors plans to bring its Super Cruise semi- autonomous highway driving technology to its entire U.S. lineup after it rolls it out to all Cadillac vehicles in 2020. Mark Reuss, GM's executive vice president for global product development, made the announcement at the Intelligent Transportation Society of America conference in Detroit. Automotive News reports he also announced plans to offer vehicle-to-everything (V2X) communication in a high-volume Cadillac crossover by 2023 — technology that will also eventually spread across the luxury brand's portfolio. Super Cruise is GM's semi-autonomous, lane-centering driving system that uses lidar mapping, GPS, cameras and sensors. The system offers hands-free driving on the highway, with an infrared camera and lights that track the driver's head position to make sure the driver is paying attention, ready to take over when needed, and not nodding off. If it senses the driver is unresponsive, it can bring the vehicle to a stop on the shoulder and activate OnStar. Super Cruise is already an option on the 2018 CT6 and standard on the Platinum trim model. You can read our First Drive review of the technology here. Meanwhile, Cadillac launched vehicle-to-vehicle technology in the 2017 CTS sedan, allowing equipped Cadillacs to share information regarding speed, direction and location at distances of up to 980 feet to help avoid collisions. By going one step further with V2X, Cadillac can tip off drivers to hazardous road conditions, the status of traffic lights, work zones and threats of crashes. It's the first major announcement from the luxury brand since the departure of former CEO Johan de Nysschen and his replacement by Steve Carlisle in April.
