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.

Can A Fleet Queen Become a Fullsize King?
On paper, the Chevrolet Impala is a pretty strong seller, posting annual sales that have hovered right around 170,000 units for the last two years, but it only takes one trip to practically any rental car agency to discover where the majority of those sales have come from. In fact, General Motors told Autoblog that a full 70 percent of Impala sales last year went to fleet companies for things like rental cars and government vehicles. Logic tells us that this is neither good for resale values nor name equity, so Chevrolet is getting ready to roll out an all-new Impala with improved comfort, styling and technology, hoping to turn the tables on its retail-to-fleet ratio.
Chevrolet's sedans have come on quite strong in the last few months with the introduction of the Cruze diesel and the SS sedan, but while these will likely be low-volume sellers, there's more pressure for the new Impala to perform well as GM looks to slash fleet sales and compete with the wide variety of full-size sub-luxury sedans. Riding on a platform shared with the Buick LaCrosse and Cadillac XTS, the 2014 Impala will compete against the Hyundai Azera, Ford Taurus and Toyota Avalon on the more traditional side, while also looking to take a bite out of somewhat sportier models like the Chrysler 300/Dodge Charger twins and the Nissan Maxima. We headed to sunny San Diego to see if this totally new Impala can stand on its own without the assistance of fleet companies and rental agencies. [w/video

What we know, and think we know, about the 2016 Chevy Volt

With the next-gen Chevy Volt due to make an appearance at the Detroit Auto Show early next year, bits and pieces about the new car are making their way into the press. Perhaps most importantly, the new Volt is going to have better "fuel economy and efficiency," according to GM executive vice president Mark Reuss. The current Volt gets 98 MPGe and 37 miles per gallon on premium fuel. It also has a 38-mile electric-only range. We don't know how GM will improve the efficiency or to what degree, but the logical options include making the car lighter, giving it better aerodynamics and/or improving the powertrain. To that end, one of the big things we don't know for sure includes information on the new gas-powered engine. Forbes says it will be a downsized 1.0-liter, three-cylinder mill instead of the 1.4-liter, four-cylinder used in the current model, which could certainly help the car be more efficient. The new Volt is also going to have more technology, which shouldn't surprise anyone. GM is now openly talking about how it will change the way it markets the Volt, shifting away from the mass-market mentality to focus on the regions where the car is already popular. "There's a Northeast and West Coast market for Volt, and there's nothing wrong with that," Chevy chief marketing officer Tim Mahoney told Forbes. There are rumors that the new Volt will have seating for five by adding a seat in the back. This is something a lot of current Volt owners would love, but we've heard nothing official hinting that this would be the case. We expect the battery to be the new 17.1-kWh version, or maybe even have a capacity increase, so GM would have to seriously repackage the pack to eliminate the ridge that runs from between the front seats and then back to the rear two seats. If you've heard anything official, do let us know.
