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

2015 Sierra All Terrain HD looks ready to hit heavy-duty trails

GMC is getting its heavy-duty trucks ready for the mud this summer with its All Terrain package for the Sierra 2500HD and 3500HD. Meant to blend style, tech and ruggedness, the pack includes a lot of extra chrome outside and an off-road package underneath.
The 2015 Sierra All Terrain HD trucks naturally come standard with four-wheel drive with an electronically controlled transfer case to handle things in the dirt. The Z71 off-road package is also standard, which includes Rancho twin-tube shocks, hill descent control and a skid plate. To add some style when off the beaten path, the pack includes chrome trim on the mirror caps, lower bumper and grille surround, plus LEDs around the headlights and 18-inch wheels (20-inchers are optional on the 2500HD). The 3500HD also gets chrome, adjustable outside camper mirrors. The interior receives a technology upgrade thanks to the standard rearview camera and IntelliLink infotainment that can act as a Wi-Fi hotspot through OnStar 4G LTE, read text messages and includes Siri Eyes Free for iPhone users.
The All Terrain package goes on sale on both trucks this summer and is offered on either the SLE or SLT trim levels in double cab and crew cab models. The standard engine is the 6.0-liter V8 with 360 horsepower and 380 pound-feet of torque, but the Duramax 6.6-liter, diesel V8 with 397 hp and 765 lb-ft is also available. The gas engine is mated to a Hydra-matic six-speed automatic, and the diesel uses an Allison six-speed automatic. Scroll down to read the full announcement about these heavy-duty off-roaders.

2020 GMC Sierra 1500 Interior Driveway Test | Still lagging behind

GM has caught nothing but grief for the interiors of its full-size pickups since they were redesigned. Some of it is about perspective. Ram blew everybody away with the new 1500’s interior, but it's not like the Ford F-150 is embarrassed by it. Chevy and GMC are. Even a top-shelf Sierra Denali doesnÂ’t live up to the luxurious environment its price tag would promise.  The trim of Sierra we're testing is an AT4, though. ThatÂ’s the light off-roading version of the Sierra thatÂ’s mechanically the same as the Silverado Trail Boss we recently reviewed. Looking at the interior from a pure functionality standpoint, the Sierra is perfectly fine at performing its truck duties. The seats are wide, flat and comfortable. It has huge armrests on both sides so you can stretch out as much as your truck stretches the boundaries of the road (seriously, this thing is huge). All the buttons in the center stack are well-labeled, easily found and big enough to stab away at without hitting the wrong one. It even has a volume and tuning knob. Yeehaw!  But look at the design. And the styling, or lack thereof. ItÂ’s plain and lacking in imagination. The whole center stack is just one big slab of black plastic, and the only splashes of color or style to distinguish it visually are bits of silver surrounding knobs and bits of gray surrounding air vents. That's certainly not enough to make it attractive. There are token pieces of "wood" inserted on Denali models, but they're almost hidden away along the center console and doors.  The screen looks as if itÂ’s scrunched into the top of the stack due to the vents curving in on both sides, making it look smaller than its perfectly acceptable 8-inch size. That just makes it more obvious that GM doesn't offer something to challenge the gigantic 12-inch optional screen on the Ram 1500. Not good, because size does matter when it comes to trucks, even if it's measured in a touchscreen's inches rather than engine displacement. LetÂ’s not discount how good all of the tech is in the Sierra 1500, though. GMÂ’s infotainment software that runs on the screen is glitch-free and runs like lightning through screens and menus. The performance is impressive, and of course both Apple CarPlay and Android Auto are on board.
