Costco Auto Program adds the Chevy Silverado and GMC Sierra through July

Costco members lean to the Bowtie when it comes to pickups. The big box store wrote that the Chevrolet Silverado "is currently the most requested Chevrolet and pickup truck through Costco Auto Program and has been for the past 11 years. In the 14 years Costco has partnered with Chevrolet for member-only incentives, the Silverado (when included), has been the top selling vehicle every time." Members can rejoice, because just for the months of June and July, the Costco Auto Program has added the Silverado and the GMC Sierra to its Costco Auto Savings Event. Until July 31, 2024, card-carrying shoppers can get an additional $1,000 discount on top of any manufacturer incentives they qualify for when leasing or purchasing new examples of either. The Auto Savings event includes other vehicles as well, the $1,000 incentive applicable to certain other models from Chevy and GMC, as as well Volvo and Cadillac. Tire kickers considering the Polestar 2 can get $2,000 off.  You can check out our write-up on the Costco Auto Program for all the details and the frequently asked questions. The summary is that the store works with "selected" dealers to refer customers to, about 3,000 storefronts across most automotive brands. The program comes with no-haggle pricing for any straight-up purchase. Costco offers customers a research tool to check out vehicles by type and compare specs and features. After a customer zeroes in on a car, it's time to visit the dealership for a chat with an "Authorized Dealer Contact" to examine the vehicle and go over the fine print. Haggling would only arise if the customer has a trade-in; that valuation is between the customer and the dealer. The customer can check out the Costco Member-Only Price Sheet, which "displays your prearranged pricing. The savings can be displayed in one of two ways: One version lists pricing for all models available at the participating dealership; the other will show a VIN-specific price based on the vehicle you select, including any applicable manufacturer incentives or rebates." And for those looking on the battery-powered shelves, the program offers the same $1,000 off the Chevy Blazer EV and Equinox EV.

2016 Chevy Volt will have more EV range, bigger battery

Meet the new Volt, not the same as the old Volt. That appears to be the story when General Motors introduces the 2016 Chevy Volt at the Detroit Auto Show in January. Today we're getting some more details on the guts of the new plug-in hybrid, and it turns out they're going to be much improved from the current Volt, which first went on sale at the end of 2010. Sure, the first-gen Volt did get some improvements along the way (a slightly larger battery pack, lane departure warnings) but the new Volt – which will go on sale in the second half of 2015 – marks the first time GM has been able to return to the drawing board and really make the improvements that its customers want. That's how Larry Nitz, GM's executive director of vehicle electrification explained it to AutoblogGreen today when explaining the all-new Voltec extended range electric vehicle (EREV) powertrain. "In the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability." – Larry Nitz Nitz said that the new Volt will be better in almost every sense: a bigger battery, longer EV-only range, 20 percent better acceleration in the low speed range and higher overall efficiency. This is due, in part, to the Volt's two motors being able to both act as generators and power the car. As we noted this morning, the 2016 Volt will use a larger, 1.5-liter four-cylinder engine, a version of which is already used in the Chinese-market Cruze. Nitz said that this has a number of benefits, including more power and quieter operation. "Some people would say, why did you make [the first-gen engine] so big. I would say, why did you make it so small?" he said. "It works good, our customers love it, but the reality is that if you go a little bit off and use the car a little harder, you can get the engine to need to operate at a higher speed. In an EV, that's quite noticeable. So, what we did in the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability and what it has marginally enabled is not only is it more efficient but it's also quieter." Nitz wouldn't talk about how the new powertrain might affect the two other products that use the Volt's underpinnings – the Cadillac ELR and the Opel Ampera – but if you've got a quieter option, we assume that's something ELR drivers would enjoy. But that's a story for another day.

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.
