Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis

2021 GMC Sierra 1500 Review | More towing, same truck

The 2021 GMC Sierra 1500 and the Chevrolet Silverado 1500 are close siblings, and they’re getting closer every year. One of the SierraÂ’s previous standout features, the Multi-Pro tailgate, can now be found on the Silverado for 2021, providing even fewer reasons to choose the GMC instead of the Chevy. Really, if youÂ’re looking at the more modest SLE and SLT models, the choice between the two largely depends on styling preference. The Sierra Denali is a slightly different story, as its available adaptive suspension is exclusive to GMC and notably improves both the ride and handling.  Of course, it still can't match the Ram 1500 in either regard, plus the Denali cabin continues to be a rather half-hearted attempt at luxury. Especially considering the genuinely high-lux offerings of Ram and Ford. The gap isn't so huge between the Sierra's lower trim levels and its non-Chevy competitors, but the cabin's design, quality and functionality still leave something to be desired. True, that often isn't a priority for truck buyers, but the Sierra isn't superior in enough other ways to balance it out. It's a capable truck with a compelling variety of powertrains, but it generally just doesn't go that extra mile beyond the competition as well as its Silverado sibling. What's new for 2021? Changes for 2021 are mostly equipment-related, but there were some vital towing and pricing changes made for the new year, too. All 2021 Sierra 1500s come with a suite of new towing tech detailed here. New technologies include a trailer length indicator, jack-knife alert, trailer backup guidelines, and camera enhancements that include a rear side view and cargo bed view. GMC expanded availability of the Multi-Pro tailgate, now allowing folks who opt for the lower SLE and Elevation trims to option it. The AT4 adds new Goodyear Wrangler Territory all-terrain tires and an off-road high-clearance step. Diesel buyers will be delighted to hear that GMC has lowered the price by $1,500 to $995, and raised the trailering capacity by 1,900 pounds to a more competitive 9,300. Maximum towing for the 2.7-liter turbo-four-cylinder is also up by 2,300 pounds to 9,200 pounds. GMC says the increase for the diesel is due to “better-than-expected rear axle durability,” and the four-cylinder is up because GM found the engine possesses “better-than-expected cooling performance.” What's the interior and in-car technology like?

GM natural gas-powered vans recalled due to possible leak

General Motors is recalling almost 3,200 of its compressed-natural-gas powered utility vans because of possible leaks. GM and the National Highway Traffic Safety Administration (NHTSA) released a notice last week saying that 3,196 Chevrolet Express and GMC Savana CNG vans are on recall, though no accidents have been reported due to the possible issue. The recall is specifically for vans for model years ranging from 2011 to 2014. The recall stems from a potential leak from the compressed natural gas high-pressure regulator, and such a leak could cause a fire or explosion. GM will replace the vehicles' high-pressure regulator in order to fix the problem, will do it free of charge and is instructing owners to contact Chevrolet or GMC customer service to arrange for the parts replacement. Utility vehicle makers like General Motors have pushed for fleet sales of CNG-powered vans and trucks for the past few years and have touted them for their cheaper refueling costs relative to standard gasoline, not to mention the fact that natural gas can be readily sourced from throughout North America (thanks, fracking). According to CNGPrices.com, compressed natural gas sells for about $2.22 a gallon, on average, while the AAA is pegging the average price of gas at $3.34 a gallon. NHTSA has posted information on the recall here. Featured Gallery News Source: NHTSA via Reuters Green Chevrolet GM GMC Natural Gas Vehicles CNG gmc savana
