GM recalls 200k Hummer H3s for fire risk

An issue with fires erupting in some Hummers has prompted General Motors and the National Highway Traffic Safety Administration to issue a recall for nearly 200,000 vehicles around the world. The bulk of them are in the United States. According to the first statement (below) obtained by Autoblog from GM, the issue stems from the HVAC system in Hummer H3 models. The connector module for the blower motor has, in certain cases, overheated, melted the surrounding plastic, and started a fire. 42 such cases have been reported, including three instances of occupants citing minor burns. GM confirms that two of those three cases lead to the vehicle being destroyed in the fire, but states that no crashes or fatalities have resulted. The issue affects 196,379 examples of the 2006-10 H3 wagon and the 2009-10 H3T pickup, with 164,993 estimated to be in the United States. In order to fix the issue, dealers are being instructed to replace the relevant parts of the connector and harness. In a second, unrelated campaign, GM is also calling in 50,731 Chevy Spark and Sonic small cars – 45,785 of them in the US – due to a software glitch. In those affected vehicles fitted with the base radio and OnStar system, the audio system may not be able to switch out of turn-by-turn direction mode, causing the display to go blank and all sound to mute – including key safety warnings. In addition, the system may not switch off, draining the battery. GM states that no crashes, injuries, or fatalities have resulted from this issue, and all that dealers will need to do in this case is reflash the software.

The heat could melt the plastic surrounding the connector module, increasing the risk of a fire. Dealers will replace the affected portion of the connector and harness. GM is aware of three reported minor burns and 42 fires but no crashes or fatalities related to this condition. Including Canada, Mexico and exports, the total recall population is 196,379. ### General Motors is recalling 45,785 2014-2015 model year Chevrolet Sparks, and 2015 model year Chevrolet Sonics in the U.S.

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.

2022 GMC Hummer EV Edition 1 Prototype Drive Review | Let the supertruck wars begin

MILFORD, Mich. — Hummer is high on the list of vehicles we never thought would return. The gas-guzzling brutes met their demise more than a decade ago as the industry pivoted briefly to smaller cars and General Motors shed brands during its historic restructuring. Fast-forward to 2022, and HummerÂ’s revival is at hand thanks to yet another industry shift, this time to electric propulsion. ItÂ’s expensive, itÂ’s still huge and the numbers are eye-popping to the tune of 1,000 horsepower. America loves a comeback — but it loves trucks more. We briefly tested the 2022 GMC Hummer EV Edition 1 truck at the GM Proving Grounds 40 miles northwest of Detroit. Weeks from now, Hummers will start rolling off the line at GMÂ’s EV site, dubbed Factory Zero, in the Motor City. While the Hummer SUV will undoubtedly prove its worth, GM is leading with the pickup, ambitiously calling it a supertruck and eagerly touting its metrics and mojo-generating features, like CrabWalk, against the Rivian R1T, Ford F-150 Lightning, Tesla Cybertruck, as well as gas-powered off-roaders like the Ford F-150 Raptor and Ram 1500 TRX, plus various Jeep and Land Rover SUVs. (Here's our latest supertruck spec comparo). All of them have impressed us (save the Cybertruck, which only Jay Leno and a few others have driven), but the Hummer is formidable in its own right. For one thing, itÂ’s a Hummer. The negative connotations of the old Hummers melt away when thereÂ’s a 24-module Ultium battery pack powering three motors for a range of 350-plus miles on a single charge. The old model was divisive, but a lot of people paid a lot of money for them simply because they looked very cool. HummerÂ’s familiar grille makes it bold return on our tester that looms high on its 35-inch Goodyear Wrangler Territory MT tires. It certainly looks the part of a supertruck. The cabin is roomy and airy, with the removable sky panels letting in the bright fall morning. Hummer EV chief engineer Al Oppenheiser is our co-pilot for our test, and after a quick walk-through, weÂ’re off.  The first order of business is simply mashing the throttle. The Edition 1 serves up about 1,200 pound-feet of torque, and you can make use of all of that and the four-figure horsepower to hit 60 mph in about 3 seconds. We accelerate hard, blasting over some soft ground before things get a little squirrelly and can confirm the claimed time feels legit.
