GMC Sierra Denali CarbonPro bed is finally, almost here

GMC revealed the Sierra 1500 with the optional CarbonPro bed on March 1, 2018. The bed wasn't available at launch, though. You can't buy it now, either, but it will hit dealerships with limited availability after production starts in early June, exclusively for the Denali 1500 and AT4 1500 trims. The carbon floor and sides replace the steel panels in a normal bed, providing "strength, durability, and scratch resistance" and a potential 59-pound weight saving, depending on the truck's configuration. To make sure the bed had a chance, development engineers replicated "extreme use scenarios" like dropping 1,800-pound gravel loads, 450-pound steel drums, and cinder blocks from various heights. They put a 250-pound man on a snowmobile with studded tracks, had him drive into the bed and then go wide-open throttle. We're told the result was "minimal scratching." On top of the extreme weather testing any vehicle goes through, the team also put a generator in the bed and aim the exhaust into a corner to ensure vibration and direct heat wouldn't deform the carbon fiber. Because of the finer shaping area-specific strength possible with carbon fiber, the bed provides one cubic foot of additional payload space by having its sidewalls pushed further out. The CarbonPro bed doesn't need a bedliner, and is grained at the top for better traction but smooth on the bottom for easier hosing down and dirt removal. Tie-downs at the front of the bed work with molded indentations to hold motorcycle tires, and slots in the sidewalls hold two-by-sixes. The truck maker says the carbon-lined payload area confers "best-in-class dent, scratch and corrosion resistance," but we suppose the nation's pickup truck army will prove that or not. The trucks likely won't have the hardest life at the start, since the Sierra Denali costs $56,790 before even a basic option like four-wheel drive. The real test probably won't come until around 2029, when third owners begin treating their aerospace-inspired thoroughbreds like dray horses.

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
