GMC Terrain's first generation could get recalled for headlights

According to Car Sales Base, GMC sold 745,454 Terrain crossovers from the end of 2009 to the end of 2017, all but a few of them representing the first-generation model years of 2010 to 2017. According to the National Highway Traffic Safety Administration, the carmaker will need to recall almost all, due to a problem with excessively bright headlight reflections. NHTSA takes issue with the fact that federal motor vehicle regulations stipulate how bright headlight reflections are allowed to be within a certain arc of the headlight beam axis. In a certain area of the arc, the Terrain throws two small spots of light that are about 450 to 470 candela strong where the legal maximum at that point is 125 candela — one candela being equivalent to the light from one candle. The NHTSA wants the headlights replaced for being close to four times over this reflective limit, alleging this can cause "glare to other motorists driving in proximity." GM discovered the noncompliance in 2019, then filed a notice of noncompliance that requested an exemption from having to recall the crossover. GM's counterpoint to NHTSA was that the two areas of illegality were 80 degrees outboard of the headlight and 45 degrees up. You'd have to be Slenderman or a giraffe standing on the side of the road — our words, not GM's — to be blinded by the light. The automaker hadn't heard of any incidents nor complaints over the issue. The only customer feedback GM received was a Terrain driver saying the "left headlamp seems to have a portion of the light that shines up in the trees at near a 45-degree angle." Note, that's the left headlight, so the tree in question would likely be on the other side of the road. GM said oncoming traffic wasn't impaired by the excessive brightness. Due to these these mitigating factors, GM asked for an exemption from recalling the Terrains.    This week, NHTSA denied GM's petition.

2024 GMC Sierra HD unveiled with new design and more powerful turbodiesel V8

The 2024 Chevrolet Silverado HD made its debut in September 2022, so it was only a matter of time before the GMC Sierra HD received a similar round of updates. Unveiled online, the truck gains a new-look design and a more powerful turbodiesel V8, among other changes. GMC developed the Sierra HD primarily for towing and hauling so the most significant changes are found under the hood. The available 6.6-liter turbodiesel Duramax V8 engine now develops 470 horsepower at 2,800 rpm and 975 pound-feet of torque at 1,600 rpm, figures that represent increases of 25 and 65, respectively, over the 2023 model and that match the 2024 Silverado HD's. GMC notes it increased low-end torque by about 25% by fitting a new turbocharger. The V8 spins the rear or the four wheels via a 10-speed automatic transmission.  On the gasoline side of the spectrum, the 6.6-liter V8's output stays flat at 401 horsepower and 464 pound-feet of torque. It's now bolted to a 10-speed automatic transmission, and replacing the 2023 truck's six-speed lets the engine run closer to its peak power for longer periods. Here again, rear-wheel-drive comes standard and a part-time four-wheel-drive system is available across the entire line-up. Properly equipped, the 2024 Sierra 2500 HD Crew Cab can tow up to 21,900 pounds. The standard 2500 HD's towing capacity checks in at 22,500 pounds (a 4,000-pound improvement), and the 3500 HD is capable of towing up to 36,000 pounds — that's nearly 13 Subaru BRZs. Buyers have a dizzying selection of trim levels and body styles to choose from. The range includes Regular, Extended, and Crew cabs as well as seven trim levels called Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate, respectively. The AT4X variant will not be available at launch, and the Denali Ultimate is new for the 2024 model year. Additionally, 3500 HD models can be ordered with dual rear wheels. What the truck looks like depends on the trim level. Broadly speaking, designers drew a more angular front end with a new-look grille, sharper-looking lights, and a redesigned bumper. New wheels are part of the update as well; the 3500 HD dually gets 18-inch polished aluminum wheels, and 22-inch units are optional on single-rear-wheel trucks. Finally, the color palette grows with six optional shades called Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic, and Downpour Metallic, respectively.
