GM ending stop-sale order on heavy-duty trucks

General Motors responded to an inquiry from Autoblog regarding a stop-sale order on its full-size heavy-duty pickup trucks. Here's GM's official statement. GM is committed to building the highest quality products possible. We paused delivery on a small number of HD pickups with the 6.6 liter Duramax engine last week to finalize an investigation into a potential quality issue. The investigation has been completed and the stop sale will be lifted for the small number of vehicles at dealerships.Customers can be assured GM’s heavy duty pickups are covered by a 5 year/100,000 mile powertrain warranty. The original article continues below. General Motors has reportedly sent its Chevrolet and GMC dealers a stop-sale order that applies to some examples of the 2022 Silverado HD, the 2022 Silverado MD, and the 2022 Sierra HD. The units affected by the stop-sale order may develop an engine-related problem. Citing anonymous sources, website GM Authority wrote that the Duramax 6.6-liter turbodiesel V8 in the affected trucks can hydrolock, which means liquid could enter the cylinders and cause a substantial amount of damage. The report does not specify where the liquid would come from; hydrolocking can happen by driving through a deep puddle of water, for example, but a large amount of coolant can cause it as well. The publication adds that the stop-sale order was assigned internal reference number N222362910. It also notes that the trucks included in it can't be sold, delivered to buyers, traded with another dealer, sent to auction, or even used for demonstration purposes until further notice. Earlier in April 2022, GM Authority reported that General Motors planned to buy back an unspecified number of Silverado HD and Sierra HD trucks due to quality-related issues with the 6.6-liter V8. Details about the problems experienced by customers haven't been released; all we know is that each truck will be replaced, though the replacement may not have the same equipment due to the ongoing chip shortage.

Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.

Chevy Bolt meets 2016 Nissan Leaf at LA NEDW event [UPDATE]

The 2015 National Drive Electric Week kicked off this past weekend with events happening all around the world. Our friends from Plug In America (PIA) send us some notes and pictures from one of the larger events in Los Angeles, CA. This event was special because it saw the debut of the 2016 Nissan Leaf and the west coast debut of the Chevy Bolt concept. The two electric vehicles were in the same place at the same time for the first time ever. Besides that little bit of electric vehicle history, the organizers helped facilitate 800 test drives, PIA co-founder Zan Dubin Scott told AutoblogGreen. The city of Los Angeles also gave proclamations to movie director Chris Paine (Who Killed The Electric Car? and Revenge Of The Electric Car) and the three national organizers of Drive Electric Week: PIA, the Sierra Club and the Electric Auto Association. Speakers at the event included names that should be familiar to AutoblogGreen readers: California state senator Kevin de Leon, race car driver Leilani Munter, and Dave Barthmuss of General Motors, among others. Joel Levin, the executive director of Plug In America, said during his speech that, "Electric cars are changing the world. Every time one of these vehicles gets sold, our air gets a little cleaner. We will take a big bite out of climate change. Our economy will not be subject to wild swings in gas prices. And we will not be involved in foreign wars over oil." Tell us about your own NEDW events (that happened already or are about to happen) in the Comments below. UPDATE: We received the text of Andrew Speaker's comments at the event. Speaker is Nissan's director of Electric Vehicle (EV) Sales & Marketing. We've included them below. Thank you, and good afternoon! On behalf of Nissan, we are proud to sponsor National Drive Electric Week, and we're excited to be able to celebrate it here in Los Angeles with all of you. This is actually my first National Drive Electric Week event, and I am inspired by the level of enthusiasm here today, and seeing everyone's passion for electric vehicles first hand. Nissan has had some big news in the last few days with the introduction of the 2016 Nissan LEAF, which is the world's first affordable electric car to get more than 100 miles of range on a single charge. The 2016 LEAF offers a new 30 kWh battery with an EPA-rated 107 miles of range... and its making its global debut here in Los Angeles.
