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 will likely build PHEV batteries in China soon

It's a big week for batteries. Friday, Tesla will hold a big event at its Gigafactory in Reno, NV. But even in Michigan, there are things happening on the electrified automotive front. This was proven when GM invited journalists to its Brownstown Battery Assembly Plant today, highlighting the six different battery packs it makes for nine vehicles around the world (plus a tenth, coming to Asia, that has not yet been announced). During our tour, we learned a few interesting tidbits that we thought readers would like to hear: The Cadillac CT6 plug-in hybrid launches in China this fall before coming to the US next year. GM builds the battery packs in Michigan and ships them to China for final assembly in the PHEV. For now, this is all fine for GM to qualify for China's incentives for building green cars in the country. But, as Bill Wallace, GM's director of global battery systems, told AutoblogGreen, this could change thanks to the country's 'Made in China 2025' plan. The situation is "evolving," he said, and it's a safe assumption that GM will need to build packs in China some day. For the CT6 PHEVs that will be sold in the US, the batteries will make a round trip, since GM will only build the plug-in version in China. As for the range of the CT6 PHEV, that hasn't been announced, but since China offers incentives for vehicles that get at least 50 kilometers (31 miles), that's a likely target (the US range (UPDATE: GM did announce an expected range for the CT6 PHEV in the US at the LA Auto Show last fall, saying it would "travel approximately 30 miles on a full electric charge"). The battery pack in the CT6 is also a clunky box-type thing, totally unlike the near-elegant T-shape used in the Volt. This despite the fact that the guts of the two packs are similar. Both have 192 li-ion cells and weigh almost the same, but GM tuned the CT6 pack for acceleration instead of range, the way it did with the Volt's pack. Still, the main reason the packs are different is because the CT6 is a rear-wheel drive vehicle, and the tunnel that the Volt's pack uses is occupied by the driveshaft. Despite the highly touted second-gen Chevy Volt going on sale last year, GM still has the capacity to build battery packs for the old, first-gen model. This is because the company is legally required to be able to provide replacement packs for warrantied vehicles (for up to 10 years), and the second-gen packs don't fit into the first-gen vehicles.

Recharge Wrap-up: Free chargers for Canadian ELR buyers, Renovo gets funding for EV supercar

Chevrolet offers versions of its Express passenger van with B20 biodiesel and E85 capability. Customers can buy the van with the Duramax turbodiesel V8, which is compatible with the 20-percent biodiesel blend. There is also a FlexFuel V8, which can use the 85-percent ethanol gasoline blend. It's a great option for shuttling the whole soccer team to practice using renewable fuels. Read more at Domestic Fuels. Early buyers of the Cadillac ELR in Canada will get a 240-volt charger installed at their home for free. It should help convince some buyers to adopt the range extended luxury EV. Cadillac's Chief Marketing Officer Uwe Ellinghaus says, "Professional installation of the fastest home-charging unit is a natural way to mark the introduction of ELR to the luxury market."

The impressive EV, with its 500 horsepower and 1,000 pound-feet of torque, is an inspiring vehicle built by a promising company, according to its financial backers. Toni Schneider of True Ventures says that Renovo has "created incredibly advanced technology and a beautiful machine that is well positioned to disrupt the automotive market."

Chief Executive Carlos Ghosn announced the plan at a test drive event in France on Monday. Renault has a partnership with Dongfeng Motors to build and sell its cars in China. Read more at Reuters. Germany has lifted its ban on Uber. While the German court believes the ride-hailing service is operating illegally without proper licensing for drivers, it says Taxi Deutschland waited too long to file the case against Uber. The taxi association plans to appeal the decision soon. See more in the video below, and read more at The New York Times. A new report from UC Davis claims that a global expansion of public transit could save 1,700 megatons of carbon dioxide yearly and over $100 trillion by 2050. A "high-shift scenario" would be necessary, wherein governments invest in rail and clean buses, expand biking and walking infrastructure and shift focus away from projects that encourage car use. This shift to public transit would especially be important in the US, China and India. Read more in the press release below.
