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

2023 GM full-size SUVs get Super Cruise expansion pack first

In August, GM announced it had doubled the size of the network of roads available to its Super Cruise hands-free driving feature. Joining the options list in 2017, Super Cruise had been limited to divided interstate highways in the U.S. and Canada. The expansion opened 200,000 miles of additional divided interstate highway as well as major, undivided highways. Both coasts benefit, but there will be a lot more relaxing motoring on the East Coast especially. North of the border, six of the 10 Canadian provinces add enabled roads. Problem is, no GM vehicles have been able to take advantage of the boon. That changes this month, the automaker saying four of its full-size SUVs in specific trims are first in line to make use of the expansion. The SUVs are: 2023 Chevrolet Tahoe Premier and High Country 2023 Chevrolet Suburban Premier and High Country 2023 Cadillac Escalade, Escalade ESV, and Escalade-V 2023 GMC Yukon Denali Ultimate  The vehicles need to have been built on or after October 3, 2022, a production timeline GM says should put the first examples in customer hands this month. The least expensive way to get into Super Cruise is with the two-wheel drive, $77,625 Chevrolet Tahoe Premier with the 3.0-liter inline-six Duramax diesel and the Advanced Technology Package. Vehicles that use the GM's Vehicle Intelligence Platform electrical architecture and already have Super Cruise will receive an over-the-air update "in the coming months" to access the new roads, at no cost to owners. Since other products like the Cadillac CT4 and CT5, Chevrolet Silverado, and GMC Sierra work with the VIP platform as well, they probably aren't far away from the extra capability and they'll bring a lower financial bar to entry.  Related video:

2019 GMC Sierra 1500 All Terrain spied with raised suspension, off-road tires

The 2019 GMC Sierra is here, though we've only seen the two top-tier trims, SLT and Denali. As past spy shots show, the Chevy Silverado's corporate sibling has more on the way. We now have a new batch of images showing what looks like the new All Terrain package, sort of a GMC equivalent to the Silverado's Trail Boss guise. The current All Terrain package is available in three different tiers on the Sierra SLT: All Terrain, All Terrain SLT Premium and All Terrain X. In addition to equipment from the Z71 package (skid plates, suspension upgrades), the All Terrain package adds Rancho shocks, an Eaton locking rear differential and more aggressive tires. There are some additional features and appearance changes, too. The more aggressive All Terrain X adds things like a cat-back exhaust and Goodyear Wrangler DuraTrac tires. The truck in these spy shots is definitely wearing different wheels and tires than the Sierras we've previously seen. It also looks like it's sitting a little higher, just like the Silverado Trail Boss. This also looks to be an SLT model as it doesn't have the MultiPro tailgate. Expect the 5.3-liter and 6.2-liter V8s to return, but don't rule out a diesel-powered Sierra All Terrain sometime down the line. Related Video: This content is hosted by a third party.
