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.

2015 GMC Yukon and Yukon XL hit the floor at LA

The middle child of General Motors' trio of truck-based SUVs, the GMC Yukon and long-wheelbase Yukon XL, received their auto show debut at today's 2013 Los Angeles Auto Show. Showing off a bigger, bolder look, particularly on its Denali trim, the Yukon sports prominent chrome grille instantly identifies GMC's new top-end SUV.
The Yukon is will come to market with a pair of engines. The base 5.3-liter V8 pumps out 355 horsepower and 383 pound-feet of torque, while the higher-end models benefit from the same direct-injected, 6.2-liter V8 as the Escalade. That engine makes 420 horsepower and 450 pound-feet of torque, with fuel economy seeing a likely boost thanks to an active fuel management system. Like the Tahoe, Suburban and Escalade, the Yukon takes advantage of a six-speed, column-mounted automatic transmission.
The cabin has seen significant upgrades in terms of materials and technology, with an eight-inch touchscreen display and IntelliLink standard in both Yukon and Yukon Denali. Fold-flat second and third-row seats come standard, while a power option is available, as well. Other techy features include active noise cancellation and standard Bose stereos.

GMC Syclone spools up a storm on Jay Leno's Garage

A storm was brewing on American roads in the early 1990s. That's when Detroit's automakers were producing some of the hottest performance trucks ever devised – models like the Ford Lightning, GMC Typhoon, and its flyweight pickup sibling, the GMC Syclone. Jay Leno just happens to have one of the latter in his garage, and took it out to showcase in this latest video segment. The Syclone was an exercise in absurdity, and could not only trounce any other pickup on the road, it could outrun anything else GM made and just about anything else on the road – beating Ferraris and Porsches off the line. In a pickup, for crying out loud. The kicker is that its engine wasn't such a monster, either: under the hood sat a 4.3-liter turbocharged V6 pumping out what would seem by today's standards to be an adequate 280 horsepower and 350 pound-feet of torque. Even the smaller of the EcoBoost V6s available in today's Ford F-150 produces more than that. But in a lightweight, compact pickup, those figures were enough to propel the Syclone to 60 in 4.3 seconds and run the quarter-mile in 13.6 seconds. Long before the dune-jumping Ford F-150 SVT Raptor or even the Viper-powered Dodge Ram SRT-10, GM made fewer than 3,000 Syclones based on the compact Sonoma (sister to the Chevy S-10) and another 4,700 of the Typhoon, which was mechanically similar but more practical (albeit heavier) wagon bodywork from the Jimmy. But as Jay aptly points out, the Syclone was the one you wanted. Scope it out in the ten-minute video clip above.
