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 pushing back on proposed pickup and SUV brake recall [w/poll]

Through the first six months of 2014, General Motors has recalled 29 million cars and trucks in 54 different actions. If your author's notoriously sketchy math is correct, that'd work out to one recall every 3.5 days (as of this writing). GM is actively fighting to make sure there isn't a 55th recall, though.
Safety critics, including perennial nemesis Clarence Ditlow of the Center for Auto Safety, are calling on GM to recall a further six million pickup trucks and SUVs in northerly climes due to corroding brake lines caused by the use of road salt. There is a catch, here, though ­- the vehicles in question are over 10 years old, and include the 1999 to 2003 Chevrolet Silverado, Suburban and GMC Sierra, as well as the 2000 to 2003 Tahoe and Yukon (shown above).
GM issued the following statement on the matter, obtained by CNN Money:

GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:
