GM finds steering flaw, decides it doesn't warrant a recall

Guess what? General Motors is back in the spotlight for not recalling something. This time, though, not only does the company have an argument against a recall campaign, but its position is supported by the National Highway Traffic Safety Administration. According to The New York Times, over 50 owners of GM vehicles have reported instances of stuck or seized steering after driving long distances without moving the wheel. One owner complained to NHTSA that the "locked" steering of their 2013 Buick Verano caused a collision with a concrete barrier in a construction zone. Along with the 2013 to 2014 model year Verano sedans, Chevrolet Cruze and Malibu sedans are also affected. Considering the popularity of those models, GM needs to have a reason for not issuing a recall, right? "Based on a very low rate of occurrence – ranging from less than one half to less than two incidents per thousand vehicles – and the fact that the condition is remedied when the wheel is turned, GM determined this was not a safety issue," spokesman Alan Adler told The Times. The company has, however, issued a technical service bulletin for owners that complain of the problem. The fix is nothing more than a software update that is covered for 10 years or 150,000 miles from new. NHTSA cited GM's actions, along with descriptions of the problems from customers, in its decision not to issue a recall, with spokeswoman Catherine Howden saying, "the symptoms described would be a brief, perceptible change in steering feel that has little to no effect on the driver's ability to safely steer the vehicle." "When terms like 'notchy,' 'stick,' 'slip' or 'feel' are used, it does not indicate a meaningful increase in steering effort," Howden told The Times via email. What do you think? Is GM in the wrong here? Should there be a recall, or is the issue so limited as to not warrant one? Have your say in Comments.

2015 Chevy Colorado gets its GearOn before Chicago

Complementing the Chevrolet Silverado Midnight Edition at the 2015 Chicago Auto Show is this, the 2015 Colorado GearOn Edition, which as the name might suggest, takes full advantage of the company's truck accessory catalog. Available on the volume LT trim and in both crew and extended cab varieties and with both the short and long-bed options, the GearOn Edition adds plenty of nifty extras designed to increase the truck's versatility and help accommodate bikes, kayaks and other outdoorsy items. The GearOn bars package, divider package and tie-down rings are supplemented an "EZ" lift and lower tailgate, side steps, gloss black 18-inch wheels, a body color grille, and blacked-out Chevy badges. And although it's not specifically called out in the attached press release, the paint on this special edition looks different than anything else in the truck's catalog. We dig it, especially with the black accents. Prices, meanwhile, start at $31,250, which is not even $1,200 more than a Colorado Extended Cab LT 4x4. We'll have more on the Colorado GearOn when it makes its debut later this week at the 2015 Chicago Auto Show, including live images to add to the pair of stocks distributed by Chevy. Until then, scroll down for the press release on the limited-edition truck. Chevy Colorado GearOn™ Edition Brings More Adventure Versatile accessories package maximizes cargo capability; enables more fun DETROIT – Chevrolet today introduced the 2015 Colorado GearOn™ Special Edition, which blends the capability of the all-new midsize pickup truck with the versatility of the GearOn accessory system – and additional popular features. It makes its public debut Feb. 13-22 at the Chicago Auto Show. The Colorado GearOn Special Edition goes on sale this spring with a starting price of $31,250. It's offered on LT models in extended or crew cab configurations, with the long or short cargo bed and available 4WD. "Chevrolet Colorado answers the call for customers who have passions of all types and the GearOn accessory system enables them to bring more adventure wherever they go," said Tony Johnson, Colorado marketing manager. "And with Colorado offering segment-leading efficiency and capabilities, it's a combination that maximizes adventure without compromise." The GearOn accessory system is designed for easy configuration with a multitude of mounting accessories for everything from bikes, kayaks, skis and stand-up paddle boards to a bed-mounted tent.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
