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

Cadillac plans upgrades to its Super Cruise hands-free system

Not content to let Tesla hog the spotlight with lofty claims about its autonomous driving capabilities, Cadillac plans major upgrades to its Super Cruise automated driving system starting next year, when the technology starts rolling out in more models. "The system that we have today, we continue to upgrade," Brandon Vivian, Cadillac's executive chief engineer, told The Verge. 'We have over-the-air re-flash capability, and you'll continue to see us add features and capabilities to Super Cruise going forward." A fellow top Cadillac engineer told the outlet they would not share specifics but said "We want to innovate" as competitors also make advances in self-driving technology. The news comes as Elon Musk says Tesla will launch a driverless robotaxi service in some U.S. cities next year, with "over a million cars with full self-driving, software, everything." The audacious claim hinges on a new Samsung microchip for self-driving vehicles. Last year, Tesla rolled out Navigate on Autopilot, which allows vehicles to change lanes, take exit ramps and choose the correct highway interchange and exit. At the New York International Auto Show, Cadillac announced that it will equip the forthcoming 2020 CT5 sedan with Super Cruise, though not initially. The brand plans to roll out a new model equipped with Super Cruise every six months starting in 2020 and going through the end of 2021, meaning four new models with the technology in two years. Super Cruise previously has been offered only on the CT6 Platinum, and as an option on other CT6 trim levels, along with a three-year OnStar package. It uses cameras, lidar mapping and radar, plus an infrared camera mounted atop the steering column to make sure the driver isn't nodding off, looking away for too long or climbing into the back seat. There's also an LED light bar on the steering wheel and Super Cruise icon on the instrument panel to let drivers know when the system is ready, not ready and ready to deactivate. But the system can't switch lanes and only works on around 130,000 miles of divided highways that GM has mapped with lidar-equipped vehicles. Vivian said the Super Cruise setup in the CT5 will be largely the same as in the CT6 and likened it to "a half step in between" a full next generation of the technology. GM also plans to eventually roll out Super Cruise to its entire U.S. lineup following its introduction in all Cadillac models. Autoblog named Super Cruise the 2019 Technology of the Year winner.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.
