GM recalls Chevy Express, GMC Savana over rollaway concern

The National Highway Traffic Safety Administration has issued a recall notice for a small number of General Motors fullsize vans due to possible rollaway concerns. On certain 2013 Chevrolet Express and 2013 GMC Savana models, it is possible to remove the key from the ignition without the shifter being in park.
Only 980 total units are being affected by this recall, and GM is fixing the issue by replacing the ignition cylinder and associated keys. Affected Chevy vans were built during most of November and December while its GMC counterpart was only built for a week in November. The recall goes into effect on January 23, and to find out if your vehicle applies to the recall, the GM and NHTSA contact numbers can be found on the official recall notice, which is posted below.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

GMC Hummer pickup and SUV previewed in video, set to be revealed in fall

GMC has just provided us with our first good look at the upcoming Hummer EV pickup and SUV. A video was posted online previewing the two models that also happens to feature LeBron James. From clay sculptures to prototypes in various levels of completeness, GM is allowing the world a sneak preview of what’s to come. A couple of the more revealing images come in silhouette photos of both the truck and SUV at the end of the video. The truck has a big four-door crew cab and an exceptionally small bed behind it. The angle from cab to bed is also notable. ItÂ’s not easy to see exactly whatÂ’s going on since itÂ’s shrouded in darkness, but when we saw the Hummer pickup, it was rocking sail panels that resemble the ones on the truck weÂ’re looking at. The truckÂ’s general shape is off-road oriented with squared-off, sharp lines tracing the entire silhouette. Its big, knobby tires and blocky wheels are clear indicators of what GM was aiming for with this electric pickup. As for the SUV, comparisons to the Ford Bronco four-door will be inevitable. If our eyes are picking up the scale of this photo correctly, though, the Hummer SUV appears to be a slightly larger vehicle than the four-door Bronco is. Although, the wheelbase for the SUV is shorter than that of the Hummer truck. ThatÂ’ll help it off-road. Those small bumpers and short overhangs along with the bumper cutouts should be hugely beneficial to approach and departure angles, as well. Hummer EV prototype View 6 Photos GMCÂ’s shots of the Hummer in the studio are equally as revealing. We can see what looks to be an intense front skid plate and two big tow hooks. In addition to the off-road gear, GMC has allowed a look at the frunk. The front “grille” is one piece with the hood of the truck, so the whole assembly pulls up. That makes for what appears to be a very easy-to-load front trunk compared to other EVs that force you to lift items up and over the front of the car. The whole removable roof assembly is exposed in this video, too. We can see the crossbars that the removable panels attach to and also what the truck looks like with the tops removed. The SUV appeared to have removable roof panels from our short glimpse of it in a studio awhile back. Other new details GM mentioned in the video include Adrenaline Mode, Crab Mode and Next-Gen Super Cruise. We donÂ’t know what Adrenaline Mode or Crab Mode do yet, but theyÂ’re certainly off-road modes that GM has designed specifically for this electric Hummer.
