2022 GMC Hummer EV voluntarily recalled for battery connector issue

When vehicles from certain automakers need to return to dealers for fixes but the National Highway Traffic Safety Administration isn't involved, these situations might be called "Customer Satisfaction Programs." It is, effectively, a voluntary recall. GM Authority notes that GM has issued one such program for the GMC Hummer EV and the Brightdrop Zevo 600 van (formerly the EV 600) to deal with a battery issue. In roughly 424 total units across both populations, the high-voltage connector might prematurely corrode. If this happens, water can leak through the connector into the pack. A warning light in the gauge cluster will alert owners to the condition. GM doesn't outline the possible results of water getting into the pack, but the outcome wouldn't be ideal.    The fix is a trip to the service bay to have a technician apply sealant to the high-voltage connector.   GM says it will get in touch with Hummer EV and Brightdrop owners about making appoints with dealers. Meanwhile, owners can contact GM Customer Service at 800-462-8782 and refer to Satisfaction Program No. N222362090. Owners can also visit the GM Recall Center page and insert their VINs to find out if their vehicles are affected. Since this isn't a recall overseen by the NHTSA, the issue isn't covered on the NHTSA's site. However, there are Manufacturer Communications between GM and the NHTSA related to other H2 issues such as a calibration issue with the Hummer EV's Extract Mode and the HVAC, so owners might want to visit SaferCar.gov for the whole picture.

2024 GMC Sierra EV revealed with 754 horsepower, 400 miles of range

This is the 2024 GMC Sierra EV in all its Denali Edition 1 glory. You probably knew this was coming. After all, when Chevrolet debuts a new pickup, the GMC version of said truck is typically quick to follow. That’s exactly the case here yet again as the Sierra EV follows the somewhat recent debut of the 2024 Chevy Silverado EV. Per usual, the Chevy and GMC versions of the electric truck share a lot of similarities. TheyÂ’re also different in many of the same ways weÂ’re accustomed to within the GM pickup family. The biggest differentiator is design. If the Silverado EV wasnÂ’t your cup of tea, perhaps the Sierra EV is! Just like the Silverado EV, the Sierra rides on GMÂ’s Ultium platform. ItÂ’s being offered exclusively in Crew Cab form at launch. GMC designers emphasized its upright stance and proportions as typical truck styling. However, close examination will show a lot of curved edges and a focus on aerodynamics to achieve a lower coefficient of drag. The front grille is devoid of any flashy patterns, as GMC has opted to go for the shield aesthetic. Light is heavily used to bring a flash of design to the face — the whole grille features a light-up surround. A three-bar charging status indicator can be seen on the front end, and engineers intentionally mounted the headlights lower in the front fascia than usual. For the Denali Edition 1 (the only version of the Sierra EV available at market launch), all of the exterior trim is done in glossy black, except for the areas you might step on, which are finished in a flat black. The rear features GMCÂ’s MultiPro tailgate, and just like the Silverado EV, the Sierra EV comes with the fancy MidGate. GMC calls it the “MultiPro MidGate,” but itÂ’s the same tech used here as youÂ’ll see in the Silverado EV. With the MidGate down, you get nine feet of storage between the cab and the tailgate. Storage can extend out to 11 feet if you use the MultiPro tailgateÂ’s stopper feature with the tailgate down. Also, the MidGate can be folded with a 60/40 split, so you can get that extra length and still retain some backseat passenger room. All of the powertrain and battery tech is similar to the Silverado EV. That means you get a pair of electric motors for all-wheel drive capability with a combined output of 754 horsepower and 785 pound-feet of torque. YouÂ’ll need to be in “Max Power Mode” (we know, much less exciting than WTF mode in the Hummer EV) to realize all that power.

GM planning to put its fullsize pickups on a big diet, too

General Motors is just coming off a complete redesign of the Chevrolet Silverado and GMC Sierra for 2014, but in the US fullsize truck market, there is no rest for the weary. According to Reuters, plans are already unfurling for both trucks to drop pounds from their curb weight over the next few years, but this will unlikely be able to keep pace with the 700-pound diet targeted for the next-generation Ford F-150, a truck expected to debut late next year.
The biggest weight reduction for these trucks might not be available until the next full redesign, which will likely happen around 2019, but the article says that smaller updates could shave pounds in the meantime. Two examples given include an "aluminum-intensive" version of the Silverado that could shed 250 pounds and debut around the same time as the lighter-weight, aluminum-bodied 2015 Ford, and there is also talk of reducing weight for driveline components such as axles and driveshafts. These changes are all part of an attempt to meet strict new fuel economy standards coming in 2017, targets which will get even tougher in 2025.
