2020 GMC Sierra makes diesel and 10-speed more available

The 2020 GMC Sierra full-size pickup truck doesn't look much different than the previous model, but it brings along a number of new feature updates. Specifically, certain options are now more widely available, including some powertrain options. The model year also brings about the truck's latest towing camera and some towing app updates. We'll start with the 3.0-liter diesel inline-six and 10-speed automatic, as both are more broadly available for 2020. The diesel adds the second-lowest Elevation trim level, meaning it's available in every trim except the base Sierra. The diesel is also now an option for the CarbonPro Edition AT4 and Denali, so you aren't limited to the 6.2-liter V8 for those trims. The 10-speed automatic is finally available on the 5.3-liter V8, but it's restricted to four-wheel-drive versions of the SLT, AT4 and Denali trims – lower trims retain the eight-speed automatic. The 10-speed transmission continues to be standard with the 6.2-liter V8 and 3.0-liter diesel. GMC also added new towing-related features for 2020. It has a newly-optional rear-view camera system that can show what's behind the truck's trailer, and it can project that where the trailer is on the main display, effectively making the trailer disappear. This feature was introduced in the Sierra HD. GMC also added a feature to its trailer app that lets you store and share details on your trailer setup so that it's easier for someone else to hook it up. You can even monitor and activate functions on compatible trailers with the app. There are a number of other more minor updates. Sierras can now be optioned with adaptive cruise control. The Elevation trim is available with the Crew Cab configuration. The AT4 CarbonPro Edition gets a few extra black accents compared with the 2019 version. Pricing and availability of the 2020 Sierra haven't been announced yet, though.

GMC and EarthCruiser to collaborate on Hummer EV Pickup overlander project

GMC just announced a collaboration with overlanding vehicle builder EarthCruiser, and the end result is going to provide us with a co-developed Hummer EV Pickup. The photo you’re looking at above is the first teaser for whatÂ’s to come of the partnership. The Hummer team will be working with EarthCruiserÂ’s research and design division to develop an overland upfit solution for EVs that it says will initially be integrated into the Hummer EV Pickup. In case you werenÂ’t familiar with EarthCruiser, theyÂ’re the people that have made utterly wild overlanding vehicles like the Terranova, FX and EXP. Needless to say, EarthCruiser makes some pretty rad stuff, and none of it is cheap. GMC says this collaboration will look to use EarthCruiserÂ’s expertise gained from developing its vehicles to create an overlanding solution for the Hummer. We should expect to see EarthCruiserÂ’s engineering technologies integrated into the vehicle, which will allow the Hummer to go even further off-road and provide the ability for owners to live with their trucks in the wilderness.  The one snag with overlanding in EVs is the typically long journeys away from civilization. As an example, the EarthCruiser XP and EXP feature 60-gallon fuel tanks to ensure you can get to where you need to go and power the living situation for a long time once youÂ’re there. WeÂ’ll be interested to hear what GMC and EarthCruiser have to say about the challenges presented by overlanding in an EV. Already visible in the teaser image is what looks like a solar panel-filled roof and rear side pods for supplies. The concept truck will be presented in late summer 2023, and while no date for a production vehicle was provided, itÂ’s likely that the final truck will come soon after. Related video:

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.
