GM tells 2021 Chevy Express and GMC Savana owners to park vans outside due to fire risk

GM is telling owners of certain 2021 Chevrolet Express and 2021 GMC Savana work vans to park them outside and away from other vehicles and structures due to a fire risk. Additionally, the company is recalling 10,154 of the vans it believes to be at risk of catching fire. The breakout is 7,891 for Chevy and 2,223 for GMC.  Only vehicles equipped with the 6.6-liter V8 (the new-for-2021 engine option) are included in the recall, and it’s limited to vans produced on or prior to December 7, 2020. The problem stems from some anti-rotation tabs on the positive battery terminal that are too close to a fuse block assembly attachment post. This lack of clearance could cause the tabs to come into contact with the fuse block, causing a short circuit. GM points out that a short-circuit of this nature could cause battery drain or lead to a fire under the hood. Your warning for the time being will come in the form of a low battery voltage warning, or you might just wake up with an unexpected dead battery. GM says that it first opened an investigation into this problem on January 26 this year after it was notified of an underhood battery fire on a 2021 Express. The investigation found three other underhood fires and concluded that these fires were originating from the positive battery cable attachment near the fuse. This recall was officially posted on March 11 this year, and the National Highway Traffic Safety Administration just sent a notification out to the media yesterday. The fix is a relatively simple one. Dealers are going to remove a portion of the anti-rotation tab on both positive battery cable terminals near the fuse block assembly attachments. This increases the clearance and eliminates the risk of fire, GM says. The job will be done under warranty, and GM says it will begin contacting owners for recall work on May 3 this year.

2020 GMC Sierra 2500 HD and 3500 HD spied on public roads

We saw spy shots of the Chevrolet Silverado HD a short time ago, and now it looks like GM has got the 2020 GMC Sierra Heavy Duty trucks running around in public too. The one we're looking at here appears to be a 2500 Denali Crew Cab, distinguished easily by the same Denali grille on the 2019 Sierra 1500. Aesthetic differences between the front fascias on the 1500 and 2500 HD are small, but the 2500 is a bit more muscular in the hood and lower trim treatment. GMC doesn't look like it's hiding a whole lot with this camouflage, since the sheets over the grille and headlights are mostly transparent. The black tarp over what appears to be a hood scoop leads us to believe it will have the same type of hood design as the 2018 HD. Other interesting bits revealed here are around the rear of the pickup. We can see the same interface for the MultiPro six-way tailgate on this truck as the 1500, so at least the Denalis will have the trick tailgate (we'd expect every trim to have it, though). Just like we saw on the Silverado, the Sierra HD gets the stepside feature just ahead of the rear wheels. LED taillights are clearly visible through the thin veiling, and GM's rear steps remain as well. in addition to this 2500 HD, our spy photographers also caught a 3500 HD model. This one isn't a Denali, as the grille shows its hand again. The grille is different than any of GM's designs on the new trucks we've seen thus far, actually. GMC showed us a teaser of what a new Silverado HD grille would look like months ago, but this differs even further than that. It looks rather minimalistic under the sheet for now, with strong horizontal slats. The actual shape and design of the truck is revealed for the most part, since it's just wearing a thin body wrap. Its mirror design appears to be different from last year's, as the arm is completely solid. A sidestep right in front of the rear wheels carries over from the 2500 HD too. We imagine both this truck and the Silverado HD will debut early next year during auto show season. Related video: This content is hosted by a third party.

What the electric Hummer's size and weight means for its efficiency

The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider If you think driving a pint-sized Nissan Leaf is as good for the planet as driving a huge electric Hummer, think again.  The GMC Hummer EV uses significantly more electricity than other EVs, meaning it produces more pollution upstream.  The electric Hummer weighs 9,000 pounds and its battery weighs as much as a Honda Civic. The new electric Hummer rolls through town without a deafening engine rumble or a cloud of toxic fumes, but it doesn't exactly tread lightly.  The colossal truck weighs an astonishing 9,000 pounds. (Think two Toyota Tacomas, three Honda Civics, or 24 Shaquille O'Neals.) Moreover, the GMC Hummer EV is in many ways a supersized gas guzzler for a new era. It repackages many of the same flaws of hulking SUVs and trucks of years past — and proves not all zero-emission cars are created equal. EVs can be energy guzzlers too On the whole, electric cars use less energy than gas-powered ones. But they aren't all equally efficient.  No surprise here: The Hummer needs more electricity than any other EV on the market to move its elephantine frame. The Environmental Protection Agency rates the pickup at 47 MPGe (miles per gallon of gasoline-equivalent). For comparison, the Tesla Model 3 sedan is nearly three times as efficient, earning a rating of 132 MPGe. The Ford F-150 Lightning, another electric truck, gets 70 MPGe.  This has real consequences: Since the US gets 61% of its energy from oil, coal, and natural gas, the more electricity a car needs, the more pollution it creates upstream.  As the Union of Concerned Scientists put it: "Both EV cars and trucks are much cleaner than their gasoline counterparts, but electric trucks are responsible for more global warming emissions than electric cars simply because trucks are larger and heavier."  The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider The Hummer EV is also resource-intensive to manufacture, requiring a ginormous (and weighty) battery to give people the 300-plus miles of range they desire. You could produce three Chevrolet Bolts with the same battery cells consumed by one Hummer.
