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

GM under fire from safety advocates over braking problem caused by recall fix

Safety experts are lambasting General Motors over what they say is the automaker’s slow notification of owners of certain 2019 sedans and trucks that a recall fix could cause power braking to fail and increase the risk of a crash, the Detroit Free Press reports.  GMÂ’s original recall in December targeted about 550,000 Cadillac CT6 sedans and Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, all from the 2019 model year, over potentially defective electronic stability control and antilock brakes. In that case, GM said the errors would not show up as a diagnostic warning on the instrument cluster. But after GM had done recall work on 162,000 vehicles, about 1,700 owner have complained that their power brakes didnÂ’t work after they had the recall done and then used the OnStar app to start their vehicle. GM then issued a supplemental fix for customers whoÂ’d already had their vehicles serviced. In this case, a diagnostic warning should illuminate saying either “Service Brake Assist” or “Service ECS,” which GM says is a signal that a customer should not drive the vehicle and instead call their dealer, which will tow the vehicle and have it repaired. Safety advocates say the automaker hasnÂ’t gone far enough to protect customers. “The fact that you could potentially start a vehicle and not have brakes is a pretty risky proposition,” Sean Kane, president of the Safety Research and Strategies, which works on auto issues for plaintiffs and governmental organizations, told the Freep. “The fact that they wouldnÂ’t notify owners (sooner) is pretty stunning.” GM told the Freep it was required to notify the National Highway Traffic Safety Administration and file paperwork before it notified customers about the original recall, which was made Dec. 12. It then had to investigate and resolve the problem created by its original recall fix before alerting customers. GMÂ’s call center and dealers are contacting the remaining 900 customers who havenÂ’t yet had the update made to the original recall repair. GM also hired a vendor to send recall letters to the 550,000 customers affected by the original recall notifying them about the update. There are no known injuries or deaths related to the problem.

2021 GMC Yukon Denali adds another extra-luxe accessories bundle

For the 2018 GMC Yukon Denali, GMC added a Denali Ultimate Package that combined every option already available with some 22-inch Midnight Silver rims. In 2020, GMC expanded build options for the Terrain with a Denali Premium Package, lumping together a couple of a la carte packages as an exclusive mix of features. The 2020 Yukon Denali configurator includes a lightweight Denali Premium Package, too, but for 2021 GM Authority reports the top-tier choices will expand to include an entry-level Denali Deluxe Package along with the Denali Premium and Ultimate options. The Deluxe Package checks the boxes for the Advanced Technology Package, Advanced Security Package, and the Rear Seat Media System. The long list of tech roped in with that trio includes adaptive cruise control, enhanced automatic emergency braking, rear camera mirror and washer, interior movement sensors, glass break sensors, dual 12.6-inch rear seat-mounted screens, two HDMI ports, and wireless projection capability. The exterior showpiece is a quartet of 22-inch bright machined aluminum wheels with premium paint, affixed with wheel locks. Go with those rims and the Denali Deluxe Package costs $5,750, opting for a different set of wheels can drop the price to $3,775. On top of that, choosing the right combination of options to go with the Deluxe Package can lower the price another $500. The Denali Premium Package includes almost everything above, only omitting the Rear Seat Media Package. In place of the screens for back-seaters, the bundle installs a powered panoramic sunroof and power-retractable assist steps with perimeter lighting. Purchased with the 22-inch wheels, this assortment runs $7,000, or $5,025 with a different set of wheels. Here again, the right combination of additional packages can save $500. The Denali Ultimate Package combines everything in the bundles above, plus the Max Trailering Package that gets GMC's ProGrade Trailering System and high-capacity engine cooling. The price is $10,460 on a rear-wheel drive Yukon Denali, $11,255 on the four-wheel drive models. Choosing a different wheel only saves $1,000 in this case, and there's no extra discount available. The 2021 Yukon is expected to enter production next month at GM's Arlington Plant in Texas, Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.
