GM recalls nearly 340,000 large SUVs to fix daytime running lights

General Motors has initiated a recall campaign for more than 338,000 of its large SUVs to address a potential defect in the onboard computer software that controls the daytime running lights. In some cases, the DRLs may remain on even when the headlights are enabled, which creates additional glare for oncoming drivers at night and fails to comply with federal regulations for headlight performance.  "GM determined that the body control module (BCM) software in these vehicles, under a combination of certain pre-conditions, may fail to deactivate the DRLs when the headlamps are on," GM's recall report said. "A regulatory assessment was conducted to evaluate whether the condition presented a potential noncompliance with the DRL activation requirements in S7.10.5, Table I-a. of FMVSS 108. On October 27, 2022, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a recall for potential noncompliance with this standard." GM says the recall covers the 2021 model year GMC Yukon and Yukon XL, 2021 Chevrolet Tahoe and Suburban, and 2021 Cadillac Escalade and Escalade ESV. The company says all models produced within that operating window include the improperly programmed body control module, meaning all vehicles within the recall population may exhibit the problem. The issue was discovered by a GM engineer during validation testing in August, prompting a deeper investigation and eventually leading to the recall itself.   The module's software can be updated by GM dealers, so it should be a quick fix for customers. Notifications will be mailed to owners in December.  Related video: Recalls Cadillac Chevrolet GMC Ownership Safety SUV Luxury

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.

Chevy Colorado, GMC Canyon get updated tachometers due to graphical error

After James Bearing bought a Chevrolet Colorado, he noticed a discrepancy between the truck's spec sheet and the truck's tachometer: Chevrolet said 3.6-liter V6 in the little pickup produces 305 horsepower at 6,800 rpm, but the the tachometer indicates a redline at 6,500 rpm. So either he wasn't making as much power as he was promised, or the tachometer display was incorrect. Bearing said he asked Chevy about it but got no response. Until now. A General Motors spokesman said the rev limiter is indeed set for 6,800 rpm, but the tach graphics "are slightly off" in the Colorado and the GMC Canyon, and submitted an SAE horsepower certification to back him up. If you're wondering how such a thing got past quality control... well, let's just say you're not alone. GM is going to fix "the graphics on future trucks," which makes it sound like Bearing will just have to learn to live with the indicated redline he's got. He could always pretend he's driving a sleeper, with four more ponies waiting to be unlocked in the danger zone for those who dare.
