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 announces four new recalls, 507k vehicles affected

428,211 of these vehicles are located in the United States, 57,706 are in Canada, and 20,956 are in other markets. In its seemingly never-ending string of recalls, General Motors today announced four new campaigns covering some 506,873 vehicles. 428,211 of these vehicles are located in the United States, 57,706 are in Canada, and 20,956 are in other markets. First up is the 2013-14 Chevrolet Cruze, which is being recalled because "the inflator in the driver's front airbag may rupture and/or the airbag may not inflate during airbag deployment," according to GM. This could shoot metal pieces of the inflator into the cabin, injuring occupants during a crash. What's more, GM says that if the airbag does not inflate, this could, obviously, increase the risk of injury to the driver. A total of 29,019 Cruzes are affected in the United States, with an additional 4,066 units being recalled in Canada. The largest of the four recall campaigns involves four-wheel-drive versions of the 2014-15 Chevrolet Silverado and GMC Sierra, as well as the 2015 Chevy Tahoe, Suburban, GMC Yukon and Yukon XL. A grand total of 392,459 vehicles are affected in the US, with 53,607 more found in Canada, and an additional 20,874 in other markets. Here, the transfer case "may electronically switch to neutral without input from the driver," GM states. The automaker adds that if this occurs while the vehicle is moving, power will not be sent to the wheels. On top of that, if the vehicle is parked, it may roll away unexpectedly if the parking brake has not been set. In smaller recall news, 4,794 2013-14 Chevy Caprice police cars and SS sedans are being recalled in the US. According to GM, "If the motor gear teeth become stripped, the wipers may not operate" in these models. Lastly, 1,939 2014 Chevy Corvettes fitted with the FE1 or FE3 suspension are being recalled in the US "to repair a possible insufficient weld in the rear shocks that could lead to a fracture and/or reduce the shocks' service life." In Canada, 33 additional vehicles are affected, as are 82 more 'Vettes that were exported to other markets. General Motors is aware of one injury regarding the Cruze recall, and is not aware of any crashes or injuries in the other three recalls. Scroll down for the automaker's official release.

2020 GMC Acadia refresh brings a new engine, AT4 trim level

It's mid-cycle refresh time for the GMC Acadia, and the updated 2020 model kicks off its changes with a new face. It has a square-jawed grille seemingly pulled straight off the Sierra full-size pickup, and the size is amplified by the slender new LED headlights on either side. At the rear, the LED taillights are taller and more chiseled. A new AT4 trim level adds more visual distinction with black trim and wheels, plus all-terrain tires to make it a little more capable off road. The AT4 also boasts standard all-wheel drive. Under the revised skin, the Acadia hides one of two carryover engines, or a new turbocharged 2.0-liter inline-4. This new engine makes 230 horsepower and 258 pound-feet of torque with the help of a twin-scroll turbocharger. To make it more frugal, it's able to deactivate two of its four cylinders. The turbo engine is standard issue on the SLT and Denali trim levels. The carryover engines include a naturally aspirated 2.5-liter 4-cylinder making 193 horsepower and 188 pound-feet of torque, and a naturally aspirated 3.6-liter V6 making 310 horsepower and 271 pound-feet of torque. The V6 is standard equipment on the AT4 trim. No matter the engine, all 2020 Acadias get a 9-speed automatic transmission. The new transmission also ditches the current Acadia's mechanical shift lever in favor of an electronic shifter with the Terrain's mix of buttons and triggers. It does free up space between the seats, but the button arrangement is still as strange as it was when we first saw it in the smaller crossover. There are a handful of other little upgrades to mention. The suspension has been revised for greater comfort; the infotainment has been revised with a bigger screen, USB-C inputs and customizable profiles; and wireless phone charging is now an option. The updated Acadia goes on sale this fall, and pricing will probably be announced close to launch.
