2023 GMC Sierra AT4X could swipe a few parts from the AT4X AEV

GM recently expanded its collaboration with American Expedition Vehicles beyond the Bison herd with the 2023 GMC Sierra AT4X AEV. This Jimmy takes matters further than the standard AT4X by increasing ground clearance, approach and departure angle, and breakover angle, improvements made possible by new stamped steel bumpers and a set of 33-inch mud-terrain tires wrapping 18-inch AEV Salta wheels. GM Authority says the AT4X AEV won't be the only Sierra to get special parts, crediting sources for the news that the standard 2023 Sierra AT4X will get some of the equipment from the special trim. According to the report, at some point for the coming model year, the off-road-focused Sierra will bolt on the AEV's stamped steel front and rear bumpers, stamped steel front skid plate, and 33-inch Goodyear mud terrains. If this is true, it's an intriguing move; the equipment list is nearly everything found on the proper AEV model. Going by that list, the only bits left off would be four additional skid plates, wheels, gloss black door handles, gloss black tailgate accent, and AEV logos. Judging from the GMC retail website, the grille that debuted on the AT4X AEV will also be on the standard AT4X.  GMC hasn't announced pricing for the 2023 range yet. The pickup will be carryover, but we would expect various well-known issues to increase the $78,300 price of the regular AT4X over the 2022 model. GMA believes "it's reasonable to assume" that a standard 2023 Sierra AT4X with some AEV parts would go up even more, whenever it hits the market — and this is on top of the Sierra's $1,500 price increase from making OnStar standard equipment. And after that, of course, the proper AT4X AEV would be more again.

GM recalls 740,000 vehicles over daytime running light issue

General Motors is recalling over 740,000 vehicles due to a daytime running light issue that causes all of the affected cars to run afoul of Federal Motor Vehicle Safety Standards. Vehicles affected by this recall are spread across many of GM’s brands. Models include the 2020-2023 Cadillac CT4 and CT5, 2021-2023 Buick Envision, 2022-2023 Cadillac Escalade and Escalade ESV, 2022-2023 Chevrolet Silverado 1500, Suburban, Tahoe and 2022-2023 GMC Sierra 1500, Yukon, and Yukon XL. GM says that the daytime running lights may remain on in these cars when the headlights are activated. This is a problem, because FMVSS rules require that the daytime running lights deactivate once the headlights turn on. If the DRLs remain on, GM says that could result in additional glare, thereby increasing the risk of an accident. The cause of this failure to deactivate the DRLs comes from body control module software that “under a combination of certain pre-conditions, could fail to deactivate the DRLs,” according to GM. Other GM vehicles were tested, but due to a difference in software or hardware, they remain unaffected. If this is reminding you of another recent GM recall, youÂ’d be right, as GM recalled another 340,000 vehicles for the same issue last month. After that original issue was found within GM, the company began looking into its other cars to determine if the population was larger than originally thought. GM found the additional vehicles included in todayÂ’s recall have the problem. The fix will either be via an over-the-air update or it will require you to bring the vehicle into a dealer for a software update, depending on which vehicle you have. Owner notification letters letting folks know what is necessary are currently scheduled to go out on January 23, 2023. Related video: Cadillac Escalade Infotainment Review

GM ending stop-sale order on heavy-duty trucks

General Motors responded to an inquiry from Autoblog regarding a stop-sale order on its full-size heavy-duty pickup trucks. Here's GM's official statement. GM is committed to building the highest quality products possible. We paused delivery on a small number of HD pickups with the 6.6 liter Duramax engine last week to finalize an investigation into a potential quality issue. The investigation has been completed and the stop sale will be lifted for the small number of vehicles at dealerships.Customers can be assured GM’s heavy duty pickups are covered by a 5 year/100,000 mile powertrain warranty. The original article continues below. General Motors has reportedly sent its Chevrolet and GMC dealers a stop-sale order that applies to some examples of the 2022 Silverado HD, the 2022 Silverado MD, and the 2022 Sierra HD. The units affected by the stop-sale order may develop an engine-related problem. Citing anonymous sources, website GM Authority wrote that the Duramax 6.6-liter turbodiesel V8 in the affected trucks can hydrolock, which means liquid could enter the cylinders and cause a substantial amount of damage. The report does not specify where the liquid would come from; hydrolocking can happen by driving through a deep puddle of water, for example, but a large amount of coolant can cause it as well. The publication adds that the stop-sale order was assigned internal reference number N222362910. It also notes that the trucks included in it can't be sold, delivered to buyers, traded with another dealer, sent to auction, or even used for demonstration purposes until further notice. Earlier in April 2022, GM Authority reported that General Motors planned to buy back an unspecified number of Silverado HD and Sierra HD trucks due to quality-related issues with the 6.6-liter V8. Details about the problems experienced by customers haven't been released; all we know is that each truck will be replaced, though the replacement may not have the same equipment due to the ongoing chip shortage.
