2023 Chevrolet Silverado HD reportedly getting mammoth torque

Chevrolet just gave the light-duty Silverado a significant round of updates. It hasn't detailed the changes it has in store for the heavy-duty model yet, but a recent report claims the truck will arrive with significant engine upgrades. Without citing sources, website TFL Truck reported that the current pickup's 6.6-liter Duramax turbodiesel V8 will return in the updated model. Its displacement won't increase, but its output will reportedly grow to 505 horsepower and a mammoth 1,085 pound-feet of torque. To put those figures into perspective, the 6.6-liter makes 445 horsepower and 910 pound-feet of twist in the 2022 Silverado HD; GMC's Sierra HD is available with it as well. Bumping the Duramax's output is a way to keep up with the competition. Arch nemesis Ford offers buyers who have extremely heavy things to tow 475 horsepower and 1,050 pound-feet of torque from a 6.7-liter turbodiesel V8. Over at Ram, the most powerful engine available in a heavy-duty truck posts numbers of 420 and 1,075, respectively. If the report is accurate, Chevrolet will enviably take the horsepower and the torque crowns in the segment. What remains to be seen is what effect the increases will have on the Silverado's towing capacity. As of writing, it's capable of towing up to 36,000 pounds (approximately 15 times the weight of a 2021 Mazda MX-5 Miata). Moving out of the engine bay, the 2023 Silverado HD will receive an updated exterior design that will again help differentiate it from the smaller, light-duty model. We're expecting the next round of updates will also bring new tech features, and it's reasonable to assume that the trim structure will evolve; Chevrolet might notably shift the HD in a more outdoorsy direction to satisfy a growing demand for off-road-focused trucks in the United States. None of this is official; Chevrolet is keeping its lips sealed about the updated Silverado HD. Full details will likely emerge in the coming months, and sales are tentatively scheduled to start in time for the 2023 model year.

GM recalling 54k Cadillac SRX, HD pickup models

There are more recalls to report General Motors, but these latest actions pertain to newer examples of the Cadillac SRX, Chevrolet Silverado HD and GMC Sierra HD. With so much scrutiny on the company's recall strategy, GM is under increasing pressure to call in defective models more quickly, and it appears to be doing so here.
Here in the US, the automaker is recalling 50,571 Cadillac SRX crossovers from the 2013 model year fitted with the 3.6-liter V6 because the transmission control module programming can cause a three- or four-second lag in acceleration at low speeds. The explanation filed with the National Highway Traffic Safety Administration states, "if the following sequence occurs within two seconds: during an upshift from first to second gear (8-10 mph), the driver then brakes the vehicle to less than 5 mph, and then accelerates again," the delay can occur. According to Automotive News, the recall effects 56,400 vehicles worldwide, and the company is not aware of any crashes caused by the problem. The fix consists of a transmission control module (TCM) reflash.
In a separate recall, GM is repairing 51 Chevrolet Silverado HD and GMC Sierra HD pickups from the 2015 model year in the US. In vehicles with diesel engines and dual fuel tanks, the nuts that connect the fuel pipe to each side of the transfer pump between the tanks may be improperly torqued, which could cause a fuel leak. Obviously, this could be a fire hazard. The remedy is simply tightening the hardware. According to GM spokesperson Alan Adler, there have been no fires actually caused by the potential leak. "Only 21 of the trucks are in customer possession and they can be fixed anytime because there are no parts involved. The others are being fixed at dealerships," Adler said in an email to Autoblog.

Leveling kit now available for Chevy Colorado, but not yet for GMC Canyon

In various bits of news this year concerning the Chevrolet Colorado and GMC Canyon pickups, we kept hearing about a front leveling kit. GM Authority found a few details in early order guides in January. In February, the kit came up in relation to the Canyon's AT4 Off-Road Performance Package, and again with AEV's upgraded Colorado Bison. After three months of waiting, GMA has more info. The kit eliminates the trucks' raked stance by raising the front by one inch, using an electro-coated upper spacer and a polyurethane lower spacer in order to maintain the proper suspension geometry. Installation is a bolt-on job with low-profile nuts, but the task will require a spring compressor. Fitted properly, the kit doesn't void GM's new vehicle warranty on the Colorado. Why do we only mention the Colorado? Because for some reason, the kit isn't available for the Canyon yet as a standalone component; the GMC stays raked without one of the aforementioned option packages. For Chevy, the leveling kit is compatible with any trim in four-wheel drive except the ZR2. It cannot be installed on two-wheel-drive trucks, nor any truck wearing wheels that are 20 inches or above. The kit is available now, ordered through any Chevy dealer for $150. There is a treat in store for GMC buyers, though, but it requires spending a lot more money. GM Authority discovered that the 2021 Yukon will offer the brand's first illuminated emblem. Priced at $475 as a dealer-installed option, a backlit glow will show off the GMC logo in the grille. The brand makes the logo in red and black, it's thought the red logo will get the nod, at least at first. Only the front logo earns the spotlight, not the one on the tailgate. GMA says the tchotchke will be available on all four trims when the new full-size crossover goes on sale in a few months.
