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.

2016 GMC Sierra Denali Ultimate wants to take even more off the top

What do you do when getting to the top of Denali isn't enough? You create a higher peak called Denali Ultimate. That's what GMC has done with the 2016 Sierra, the new Sierra Denali Ultimate adding even more content and showing off the truck's refreshed face and new Denali grille. The reasoning behind this truck is perfectly sane. GMC says that in 2013 it had zero percent of the premium light-duty truck market; since that time, the brand says the segment (with an average transaction price beyond $55,000) has grown by a factor of ten, and the Sierra Denali has given GMC a 15.5-percent share. When it goes on sale in in the first quarter of next year, it can be optioned on the four-wheel drive 1500 Crew Cab with either the five-foot-eight or six-foot-six-inch bed. Standard equipment includes a sunroof, Lane Keep Assist, automatic headlights, Tri-Mode Power Steps, chrome tow hooks, and 22-inch wheels. The press release below has more. GMC Sierra Denali Ultimate: The Pinnacle of Premium Unique 22-inch wheels, expanded package of standard content drives exclusivity DETROIT, Tuesday, Nov. 17, 2015 – GMC is taking the range-topping style, craftsmanship and capability of the Sierra Denali even higher with the 2016 Sierra Denali Ultimate. It builds on the Sierra Denali's already class-leading attributes with a package of precision-crafted features designed to elevate its comfort, design and capability in the growing premium niche of the full-size truck market. GMC introduces the Sierra Denali Ultimate today, ahead of its public debut at the Los Angeles Auto Show. It goes on sale late in the first quarter of 2016. "The Sierra Denali has helped drive the growth of premium portion of the light-duty crew cab segment," said Duncan Aldred, vice president of GMC Sales and Marketing. "This truck is the ultimate expression of the Sierra Denali with greater emphasis on the bold and refined presence and advanced features that make Denali models synonymous with precision and exclusivity." Thanks in large part to Sierra Denali, which was redesigned in 2014, GMC commands 15.5 percent of the premium full-size truck segment, where average transaction prices exceed $55,000. The segment has nearly doubled in 2015 and grown tenfold since 2013, when GMC had zero percent of the market. In fact, Sierra Denali has helped GMC earn a higher share of the premium portion of the light-duty crew cab segment than of the overall full-size pickup segment.

GM issues stop-delivery for 2015 Chevrolet Colorado and GMC Canyon

General Motors is issuing a stop-delivery order for its latest midsize pickups, the 2015 Chevrolet Colorado and GMC Canyon, because the driver's side airbag might not be wired correctly. The total number of vehicles affected is still being determined.
According to the statement from GM, the problem, "affects the vehicles' two-stage airbag system by reversing the deployment sequence and disrupting the deployment timing of the driver airbag stages." That means in an accident the bag may not work correctly.
Most of the affected trucks are still on the assembly line, in transit or unsold at dealers, says GM. Until a way to repair the problem is found, customer deliveries are stopped. However, "a small number" of them are in the possession of buyers. GM is contacting these people by phone and by FedEx letter to have the vehicles returned to dealers. In the meantime, they'll be given a loaner to drive.
