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.

Recharge Wrap-up: Lyft partners with Didi Kuaidi, Cadillac uses ultracapacitors

Lyft and Chinese on-demand transportation venture Didi Kuaidi have announced a partnership. Additionally, Didi Kuaidi is investing $100 million in Lyft. The two ridesharing companies will share technology and provide interoperability between platforms. For users, this means it will be easier to get around when traveling between the US and China. "In today's rideshare environment, where every region presents a unique set of challenges and opportunities, partnering with the homegrown leader is the winning approach to Chinese expansion," says Lyft President and co-founder John Zimmer. Learn more in the video above, and in the press release below. Car2go has announced service in Miami Beach, FL. Beginning October 1, the one-way carsharing service will expand its boundaries beyond its current Miami service area to include neighboring Miami Beach. "We're thrilled to see car2go expand to Miami Beach," says Miami Beach Mayor Philip Levine. "Miami Beach residents and visitors are increasingly seeking new, environmentally conscious options to move around North, Middle, and South Beach, and carsharing is an important part of realizing that vision."

It allows for faster charging without the customer having to upgrade their electrical service panel. Delivering about 20 miles of range per hour of charging, the HCS-30 EVSE can charge most EVs in about four hours. Pricing begins at $565. Read more from ClipperCreek. Cadillac will use ultracapacitors in its stop-start systems for 2016. Rather than relying on battery power to run electrical systems while the engine is not running, the utracapacitors can provide a stable flow of energy without losing lifespan to repeated cycling. Supplied by Maxwell Technologies, the ultracapacitors are also lighter than batteries and, according to Cadillac, provide smoother restarts. The 2016 models to use the updated stop-start technology as standard will be the ATS and CTS, with the exception of the V performance variants. Read more at Green Car Reports.

GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.
