GM recalling Silverado and Sierra HD diesel pickups over fuel gauge follies

General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.
The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank - it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.
GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.

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.

GM uses wind power to build SUVs, trucks

This week started with a chill, as the Intergovernmental Panel on Climate Change issued a dire report with scientists warning, "The world we know today is not the world we will see in 50 years," with temperatures rising at their current rates. In the meantime, the trend toward purchasing more SUVs and crossovers continues. Most automakers, though, have set goals toward more sustainable production. That includes General Motors, which, somewhat ironically, plans to use wind power to produce many of its vehicles, including pickups and full-size SUVs. As the Detroit Free Press reports, several wind farms are coming online to support cleaner production as part of a partnership between GM and energy producer CMS Enterprises. At the beginning of October, the 100-megawatt Northwest Ohio Wind Farm began producing energy, supplying GM operations in Ohio and Indiana, where manufactured vehicles include the Chevy Cruze, Chevy Silverado and GMC Sierra. Hilltopper Wind Farm in Illinois will begin producing another 100 megawatts for GM manufacturing in the region. In Texas, where GM builds the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, GMC Yukon XL and Cadillac Escalade, the automaker is getting 50 megawatts from Cactus Flats Wind Farm beginning October 9. Using wind power isn't just about being green, but also for the sake of price stability. As Rob Threlkeld, GM's global manager of renewable energy told the Free Press, "You don't get the price spikes this way, like you do with fuel, and it reduces the environment footprint of the vehicle you're driving." Threlkeld said that renewable energy has already meant "millions of dollars in savings" for GM. GM plans to power all of its global operations with renewable energy by 2050. This week, the automaker was ranked 76 on the EPA's "National Top 100 List" of green manufacturers. It was the only automotive company listed.
