2020 GMC Sierra HD offers loads of tech

The 2020 GMC Sierra HD has finally been revealed, and it's a heck of a lot more subtle than the Silverado HD. Whereas the Chevy went with a wildly exaggerated version of the split grille and headlights the truck is known for, the Sierra simply builds on the 1500 model's design with an expanded grille that doesn't appear to be as tall or wide as the Chevy's. That's not to say it looks unimpressive, though. It's still got a massive fascia, it's just not as extreme as the one with a bowtie on it. With the Sierra's unveiling, we get more details about the powertrains available on the heavy duty GM trucks. The 6.6-liter turbocharged Duramax V8 makes 445 horsepower and 910 pound-feet of torque. That's the exact same output as the engine in the old models. But this time, the engine will be mated to an Allison-branded heavy duty version of the GM 10-speed transmission. A gas engine will also be available, but GMC hasn't revealed details on it yet. The new Sierra boasts a range of new features, some that are unique to it, and some shared with the Silverado. A shared feature is the new steps in the bed sides that are standard on all Sierra HD models. Unique to the brand is the MultiPro tailgate with fancy drop-out step. This tailgate will be available on all trims, and it's standard starting with the mid-level SLT. There are some useful visibility features being shown on the new Sierra, too, such as an available trailer camera system with 15 possible viewpoints, and it can virtually show the rear view on the screen as if there wasn't a trailer in the way. GM's rear-view mirror screen also makes an appearance. An AT4 off-road trim will be available on the new Sierra HD. It has slightly different styling with dark grilles and trim. Off-road upgrades include reworked springs and shocks, skid plates, standard all-terrain tires and a locking rear differential. Pricing has not yet been announced, but the truck goes on sale this summer. Details on prices as well as further specifications will likely be announced near the on-sale date.

GM recalls 55,000 trucks, SUVs for separating axles, fuel pump failures

General Motors issued four separate recalls covering eight of its truck and SUV models for issues related to fuel pump and half-shaft failure. In total, the four campaigns include more than 55,000 vehicles spread out over three brands and six model years, but they've sorted themselves neatly into two categories. Let's dive in.  Axle separation Four models are being recalled for potential axle separation: The 2023 Cadillac XT5, 2023 GMC Acadia, 2023 Chevy Blazer and 2023 Chevy Traverse. The number of units affected is incredibly small (10 units each times two recalls, for a total potential population of just 20 cars). In each case, a small number left the factory with half-shaft assemblies that may have been missing the retention rings that keep them in place, possibly allowing the axles to separate or eject from the transmission. In the case of the XT5 and Acadia, it's the right-side axle assembly; Chevy dealers, however, will have to check the left side.  Fuel pump failure Again, we have multiple vehicles being recalled for similar issues, but in this case they're a bit more distinct. The first of these recalls covers the 2021-2022 Chevy Equinox and 2022 GMC Terrain. GM says a supplier-initiated change may have led to fuel pumps shipping with inadequate clearances to allow for the prescribed flow of fuel, meaning the pump could starve the engine. Customers experiencing the issue may see a check engine light and experience engine hesitation. In some cases, the cars may not start at all. Chevy and GMC will replace the units in question with correctly specified pumps.  The second recall covers a fairly specific cross-section of GM's HD truck lines. 2017-2019 Silverado and Sierra HD trucks sold with the diesel engine and a dual-tank configuration may have shipped with a rear fuel pump that is susceptible to fouling by debris, preventing fuel from properly transferring to the front tank, or, in extreme cases, resulting in a collapse of the rear tank. This issue can lead to inaccurate/erratic fuel tank readings, engine hesitation, a check-engine light or failure to start.  In both cases, GM will inspect and replace faulty units free of charge for customers. Expect notifications to be delivered by March.  Related video: Recalls Cadillac Chevrolet GMC Ownership Safety Truck SUV

eBay Find of the Day: 1976 GMC Motorhome is a jolly green giant

If you have a need to relive the 1970s, then here is the vehicle for you. This groovy blast from the past is a 1976 GMC Motorhome currently for auction in Florida on eBay Motors, and it is one green machine - just not in the modern sense.
The seller claims that this beast has had just two owners and has covered a mere 61,308 miles in its decades on the road. It's reportedly never been restored or repainted and comes with all of the necessary books and manuals. A 7.5-liter (455-cubic-inch) Oldsmobile V8 with a three-speed Turbo-Hydramatic automatic transmission powering the front wheels propels this far-out RV, and the double set of rear wheels out back use a self-leveling air suspension to provide a cushy ride.
The purported low miles and good condition really make this GMC a stand out, though. The exterior combination of lime stripes and beige with just a touch of green is like nothing else on the road today. Plus, the polished bumpers and wheels make it all pop. Inside, it's even better with monochromatic green upholstery and shag carpet. It features everything you'd ever need on a long trip, including a bathroom, kitchenette and lots of seating. The only hint of modernization is an HD TV next to the stove, but its size is a perfect fit for the hole there.
