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.

How two-state Chevy Spark EV outsold 50-state Volt last month

Is it really just about price? Last month, the Chevy Spark EV got a sizable price drop of $1,500 alongside a lowered lease price of $139 a month (down from $199). Those numbers, particularly that cheap lease, had a tremendous impact on how many all-electric Sparks GM sold last month. There were 920 Spark EVs sold in April, and the Spark EV is available in only two states: California and Oregon. Sales will start in Maryland in the third quarter of 2015, but there are no pre-orders taking place there, so all 920 were West Coast sales. To be more precise, there were about 864 Spark EV leases signed last month, since 94 percent of those 920 sales were retail leases. As Annalisa Bluhm from Chevrolet communications told AutoblogGreen, that level was, "simply insane." "In those states which offer Spark EV, you can get a 1LT Spark EV for less than a 1LT Spark, with more features" Bluhm said. "Factor in that you will save approximately $82 per month by abstaining from gas, and it's easy to see why people went crazy for the Spark." Let's put 920 into perspective. For one thing, it's crazy up from the 151 Spark EVs sold in March 2015 and the 97 sold in April 2014. It's also almost as many as GM sold all last year, and way more than two years ago. The General sold 653 Spark EVs in 2013 and 1,146 in 2014. To throw in a comparison with GM's longstanding plug-in champion, the aging Volt, the Spark EV came out ahead in the monthly tally for the first time ever. In April, the Volt sold 905 units. The plug-in hybrid's best-ever sales month was August 2013, when it sold 3,351 units. Counting all models and powertrains, Chevy sold 3,743 Sparks in April. So, does this success mean that Chevy is looking to bring the Spark EV to more markets? Bluhm said that GM is considering other states and is always looking at the business case, but has "nothing to announce yet."

2016 Chevy Volt sneak peek at CES

Here it is, folks – your first real glimpse at the 2016 Chevrolet Volt. The gasoline-electric sedan will officially debut at the Detroit Auto Show next week, but Chevy gave us a sneak peek of its redesigned Volt at a media event in Las Vegas late Sunday, as part of its CES festivities. There isn't a ton to see here, and sorry about the low quality video (and for us not standing front and center during the reveal). But we can clearly see the car's redesigned front fascia – something recently previewed at a fan event in Los Angeles. For another view, check out a high-res photo of the new Volt from our friends at The Verge, here. Chevy even tweeted a photo of the Volt's new nose on its official Volt Twitter account, which you can see below. The automaker didn't divulge any details about its new Volt, but we already know quite a bit. For starters, the Volt will use a new, 1.5-liter gasoline engine and won't require premium fuel. It'll have more EV range and a bigger battery, too. We'll have a whole mess of information when the 2016 Volt is fully revealed in Detroit in about one week's time. In the meantime, here are some more looks at the Volt, courtesy of the Twitterverse. We're so excited about #NextGenVolt we brought it out early at #CES2015!
