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.

Sinkhole Opens Up In National Corvette Museum, Swallows Eight Cars

More cars are being moved inside the National Corvette Museum in Bowling Green, Ky. to avoid falling down the same sinkhole that swallowed eight classic sports cars early this morning, Autoblog reported. Museum officials said the hole was discovered when motion sensors activated around 5:45 a.m. The rescue mission can be viewed on the museum's live feed cameras, which weren't working after the sinkhole emerged. A 1993 ZR-1 Spyder and a 2009 ZR1 "Blue Devil," both on loan from General Motors, were among the cars that fell into the sinkhole. The museum owned the other affected Corvettes, which included a 1963 Corvette, a 1984 PPG Pace Car and the 1 millionth Corvette ever produced. The state of the cars at the bottom of the hole isn't known, but trial lawyer and sinkhole expert Ted Corless said the cars may be a total loss for the museum and GM. "Most states, including Kentucky, exclude damage caused by sinkhole activity," he said. "There will be, in all likelihood, a claim made, but a lot of policies would specifically exclude these kinds of damages." Corless has 15 years experience dealing with sinkholes. He said that typically neither the building, nor the cars themselves are protected under their insurance policies. "I would have to say, more likely then not, they're going to have an uninsured loss measured in the hundreds of thousands of dollars." The museum is closed Wednesday while a structural engineer assesses the damage.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.
