GMC Hummer EV recalled over improperly sealed battery pack

Over 700 units of the GMC Hummer EV built during the 2022 and 2023 model years will be recalled due to an improperly sealed battery pack that lets water in. The firm issued a stop-delivery order at the same time as the recall, and it hasn't found how to fix the problem yet. Assigned recall number 22V-771 by the National Highway Traffic Safety Administration (NHTSA), the campaign includes 735 examples of the Hummer EV and 89 units of the BrightDrop Zevo 600 van. These two vehicles are pegged on opposite ends of the automotive spectrum, but they're affected by the same problem: "the high-voltage battery pack enclosure in some of these vehicles may not have been properly sealed," GMC notes, adding that "flanges on the battery pack enclosure may not have been properly primed or electrocoated." Water can wreak havoc in a high-voltage battery pack. GMC told NHTSA that it has found three EVs with this problem: an internal test vehicle that lost power while driving and two customer-owned vehicles that wouldn't start. As of writing, the firm is not aware of any accidents, injuries, or fires related to the issue, and GMC estimates that only about 1% of the recalled EVs are affected. GMC began notifying dealers of the recall in October 2022, and it plans to start reaching out to owners on November 28, 2022. However, a fix hasn't been found yet. In the meantime, the company issued a stop-delivery order and asked dealers not to attempt their own repairs. This isn't the Hummer EV's first run-in with water-related problems. In August 2022, General Motors voluntarily recalled 424 units of the Hummer EV and the Zevo 600 van due to a high-voltage connector that can prematurely corrode. The problem also let water leak into the battery pack, though it sounds like fixing it was reasonably straight-forward and involved applying sealant to the connector.

GM is training more first responders for EV emergencies in the U.S. and Canada

GM is training more first responders to be able to handle emergencies involving electric vehicles. The automaker is "significantly expanding" its EV First Responder Training program in the United States and Canada as electric vehicle sales continue to grow. Its initiative will primarily focus on training firefighters and equipping them with the necessary knowledge about full electric vehicle technologies. GM says it's hoping to dispel misconceptions when it comes to handling EVs in emergency situations. One of those misconceptions is that water is dangerous around EV batteries — turns out the recommended way to put out lithium-ion battery fires is by using copious amounts of water.  Andrew Klock, a senior manager of education and development at the National Fire Protection Association (NFPA), said: "The best way for the public and private vehicle fleet owners to rapidly adopt EVs is to train firefighters and emergency responders on how to handle incidents involving battery powered vehicles. The fire service has had more than 100 years to gain the knowledge needed to respond to internal combustion engine fires, and it is critical that they are now educated on EV safety." The NFPA held trainings of its own that had benefited 300,000 first responders, but it believes more than 800,000 members of the community still need further training.   GM previously piloted the program in southeast Michigan, but now it's conducting training events across Michigan and in Fort Worth, Texas, as well. Later this summer, it's bringing the program to metro New York City and Southern California. Participants will have to attend four-hour sessions, with up to two per day, held in various venues, such as fire houses and dealerships. Interested first and second responders can register through the program's dedicated website and earn a certificate from the Illinois Fire Service Institute if they score higher than 70 percent on the learning assessment by the end of their training.  The automaker already has a few EV models on the market, including the Chevy Bolts, the GMC Hummer EV and the Cadillac Lyriq. It has huge electrification plans for the future, though, and training responders could help make potential customers more receptive to the idea of switching to electric vehicles. GM aims to launch 30 EV models by 2025 and to exclusively sell EVs ten years after that. Related video: Green Cadillac Chevrolet GM GMC Safety Electric

Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.
