GM recalling Silverado and Sierra HD diesel pickups over fuel gauge follies

General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.
The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank - it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.
GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.

2016 GMC Sierra All Terrain X is cool but no Raptor threat

If you want a brutish off-roader from Ford or Fiat Chrysler Automobiles, you're spoiled for choice. There's the F-150 SVT Raptor, the Jeep Wrangler, and the Ram Rebel and Power Wagon. But since General Motors killed the Hummer brand, it's been without any real competitor to those trucks. The new, special edition GMC Sierra All Terrain X is not going to be that vehicle, but it's close enough to be worth a look. The oft-overlooked Sierra All Terrain's off-road suspension and Eaton locking rear differential give it some real trail credentials. The All Terrain X builds on both with cosmetic and performance upgrades. For most owners, the big draw will be the brawnier 5.3-liter V8. Fitted with a performance exhaust, it should deliver a meatier tone, and according to GMC it bumps output up from 355 to 365 horsepower. The other big performance upgrade comes from the tires, knobby Goodyear Wrangler DuraTrac MT mud-terrain-rated things. The tires and their accompanying 18-inch black aluminum wheels are nice touches. Cool as the All Terrain X might be, it strikes us as an odd strategy for the GMC brand. For one, the trail-ready tires and performance exhaust of the All Terrain X don't seem to fit into the more premium market position that GMC occupies. Moreover, Chevy already has an off-road-oriented pickup in the new Colorado Z71 Trail Boss. Visual upgrades like the black bed-mounted sport bar, LED off-road lights, blacked-out accents, and the 18-inch wheels, the look of the All Terrain X is more in line with the Colorado Trail Boss theme. It's just our two cents, but it seems like attaching the All Terrain X's aesthetic to the Silverado would have been a stronger strategy, and would give Colorado buyers a larger off-road-focused truck to aspire to. You can look for the special edition All Terrain X in GMC dealers this spring, with prices to be announced closer to the on-sale date. Read on for the official press release from GMC.

2015 GMC Canyon Nightfall Edition rumbles in under the radar

Buyers enticed by the new 2015 GMC Canyon will want to take a look at the new Nightfall Edition. Unveiled here on the floor of the 2015 Detroit Auto Show, the Nightfall is based on the mid-level SLE trim level in four-door crew cab bodystyle, but upgrades with a stealthy appearance and bundled extras. It's decked out in Onyx Black paint, for starters, but also has a blacked-out grille and side steps, a spray-in bedliner and 18-inch wheels with darkened inserts, as well as a polished exhaust tip, remote start and automatic climate control fitted as standard. The only choice left up to the buyer of this murdered-out mid-size pickup is whether to get it in 2WD or 4WD. Either way, motivation is provided by the Canyon's 3.6-liter V6 with its 305 horsepower and 269 pound-feet of torque. Pricing has yet to be announced, but considering that the SLE on which it's based starts at $30,980 and that the SLT comes in at $34,345, we'd expect the Nightfall to be positioned in the low 30s, with another few grand for four-wheel drive.
