GM tells NHTSA pickup truck electronic glitch is 'inconsequential'

General Motors has been enduring some serious problems with recalls recently, and it is hoping to avoid launching another major safety campaign. 200,921 2014 Chevrolet Silverado and GMC Sierra pickups are under the microscope due to a rare problem with their instruments, an issue GM calls calls "inconsequential to motor vehicle safety." The Detroit-based automaker believes that the glitch is so minor that it has filed a petition with the National Highway Traffic Safety Administration asking the government safety watchdog for permission to pass on recalling the vehicles.
The fault at issue can occasionally cause the instrument cluster to reset when drivers use the steering wheel controls to browse songs from an external media device connected to the truck's USB ports. If a song's title information exceeds 2,000 bytes, according to The Detroit News, then the instrument panel can reset, which in turn causes the gauges, shift position indicator and cruise control telltale to turn off briefly. When rebooting, other instrument panel lights may briefly illuminate without their functions actually being activated. GM claims that if this does happen, the instrument display lights go out for about 1.5 seconds and the bulb check lasts a further five seconds. However, this snafu has no actual affect on the truck's operation. The glitch is present in trucks built between January 29, 2013, and October 28, 2013.

Trademark application points to evolution of new Hummer EV logo

A trademark application has revealed yet another evolution of the logo expected to adorn GMC's new Hummer EV pickup truck, bringing back the big "H" badge utilized on the H2 and H3 model lines of the expanded SUV lineup's heyday.  The image included with the filing depicts a logo that should be familiar to Hummer fans (or really any American who left their house between 2003 and 2010), with "EV" supplanting the old numerical model indicator. The "Hummer" and "EV" typeface appears to be a direct lift from a filing that surfaced back in April.  This should provide some comfort to folks who are fans of the idea of a future-proofed, all-electric pickup, but want something that embodies the charisma and road presence of the models sold in Hummer's now-deceased, not-so-environmentally-spectacular incarnation. While we don't yet know really any details of the new all-electric SUV, we do know it will be sold via GMC dealers, meaning the revived nameplate will not bring the rest of the Hummer brand along with it.  We haven't really seen much of the new truck, save for teasers and hints here and there. Even the "reveal" back in June only gave us a vague, big-picture look at the truck's silhouette, and various companion images and videos have hinted at features such as a removable roof assembly.  The truck’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. 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.

GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.
