GM recalls 638,000 U.S. SUVs, trucks for unintended braking

WASHINGTON — General Motors is recalling 638,000 U.S. sport utility vehicles and pickup trucks because a wheel-speed sensor could fail and cause unintended braking, it said Thursday. The recall covers 2015-2020 Chevrolet Suburban, Tahoe, and Yukon and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. The sensor failure could result in unintended activation of the driveline protection system, and cause unintended braking of the wheel on the opposite side of the failed sensor. That could cause the vehicle to pull to one side unexpectedly, increasing the risk of a crash, the Detroit automaker said. GM said it was not aware of any crashes relating to the issue but found 150 field claims alleging the condition caused unintended braking or lateral vehicle motion. A GM dealer in May submitted a warranty report relating to the issue in a 2018 GMC Yukon, and two days later, a GM brand quality manager submitted the report to GMÂ’s Speak Up For Safety program that tracks potential safety issues, which prompted a GM investigation and testing.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

GM’s Charlie Wilson was right: Stronger regulations can help U.S. automakers

Charlie Wilson had been the president and CEO of General Motors before being nominated to become secretary of defense by Dwight Eisenhower. During his Senate confirmation hearings, he controversially said, "For years I thought what was good for our country was good for General Motors, and vice versa." And he was right. While car companies aren't necessarily the most progressive when it comes to things that might have the slightest possibility of political blowback, General Motors should be credited for doing something absolutely forthright in this regard with its announcement that it wants the federal U.S. government not to squash the California Air Resources Board's emissions requirements but to actually create a 50-state "National Zero Emissions Vehicle" program that, in the words of Mark Reuss, executive vice president and president, Global Product Group and Cadillac, "will drive the scale and infrastructure investments needed to allow the U.S. to lead the way to a zero emission future." Filing comments to the Safer Affordable Fuel-Efficient Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks is one thing. But a graphic the company developed for this announcement — shown above — is something else entirely, something that is absolutely credible, creative and clever. There is a photo of a Chevrolet Bolt EV driving along a highway, which seems to be in Marin County (based on the blurred San Francisco skyline in the background). Text on the photo states: "It's Time for American Leadership in Zero Emissions Vehicles." It seems to say, in effect, "If we want to make America great again, then we're going to do it by leading in technology, not by retreating behind weakened regulations." General Motors understands that the auto market is globally competitive, and if U.S.-based companies are going to be in the game, then they'd better be able to out-innovate the companies based elsewhere, where emissions and economy standards are not being weakened.
