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

Best car infotainment systems: From UConnect to MBUX, these are our favorites

Declaring one infotainment system the best over any other is an inherently subjective matter. You can look at quantitative testing for things like input response time and various screen load times, but ask a room full of people that have tried all car infotainment systems what their favorite is, and you’re likely to get a lot of different responses. For the most part, the various infotainment systems available all share a similar purpose. They aim to help the driver get where they're going with navigation, play their favorite tunes via all sorts of media playback options and allow folks to stay connected with others via phone connectivity. Of course, most go way beyond the basics these days and offer features like streaming services, in-car performance data and much more. Unique features are aplenty when you start diving through menus, but how they go about their most important tasks vary widely. Some of our editors prefer systems that are exclusively touch-based and chock full of boundary-pushing features. Others may prefer a back-to-basics non-touch system that is navigable via a scroll wheel. You can compare it to the phone operating system wars. Just like some prefer Android phones over iPhones, we all have our own opinions for what makes up the best infotainment interface. All that said, our combined experience tells us that a number of infotainment systems are at least better than the rest. WeÂ’ve narrowed it down to five total systems in their own subcategories that stand out to us. Read on below to see our picks, and feel free to make your own arguments in the comments. Best infotainment overall: UConnect 5, various Stellantis products Ram 1500 Uconnect Infotainment System Review If thereÂ’s one infotainment system that all of us agree is excellent, itÂ’s UConnect. It has numerous qualities that make it great, but above all else, UConnect is simple and straightforward to use. Ease of operation is one of the most (if not the single most) vital parts of any infotainment system interface. If youÂ’re expected to be able to tap away on a touchscreen while driving and still pay attention to the road, a complex infotainment system is going to remove your attention from the number one task at hand: driving. UConnect uses a simple interface that puts all of your key functions in a clearly-represented row on the bottom of the screen. Tap any of them, and it instantly pulls up that menu.

NHTSA approves hybrid rearview mirror display in Cadillac CT6, Bolt EV

The Chevy Bolt EV prototype doesn't just have a fancy new all-electric powertrain. Just outside the driver's line of sight is a newfangled rearview mirror, one that can turn into a screen that shows a moving image from the rear-facing camera. Speaking to NPR's Robert Siegel yesterday, Department of Transportation secretary Anthony Foxx said that NHTSA has now approved this type of mirror/screen for use in vehicles. According to a letter from NHTSA to General Motors, GM will likely use this Full Display Mirror first in the 2016 Cadillac CT6 before coming to the Bolt. In its letter to GM, NHTSA said that the Full Display Mirror will only qualify as a standard rearview mirror as long as there are normal side mirrors in place. In other words, don't expect to see cameras and screens replacing all the mirrors in a motor vehicle just yet. @AutoblogGreen @NPR - #NHTSA has OK'd GM rear-view system that can switch between mirror & camera views. pic.twitter.com/6CBeIit10v — Anthony Foxx (@SecretaryFoxx) February 22, 2016 The Full Display Mirror was developed by Gentex, which has long worked with GM. The FDM debuted in 2014 and some people hoped it would also make its way into the Tesla Model X. Gentex, which also makes auto-dimming mirrors, says that it has "set out to develop the technologies and core competencies necessary to manage this evolution of the rearview mirror." The Chevy Bolt EV will start at $37,500, before incentives. The 200-mile EV will go into production late this year for likely sale in early 2017. Related Video:
