GM announces six new recalls, covering 3.5 million vehicles

General Motors has just initiated another crushingly large recall, this time affecting some 3.36 million vehicles built between 2000 and 2014 and sold in the US, Canada and Mexico. Once again, the issue surrounds the cars' ignition switches, which can be kicked out of the run position if they're carrying extra weight or if they experience a "jarring" event. In this particular case, though, GM will modify the keys, rather than the ignition itself.
A four-by-six-millimeter hole will be drilled into the key, which will more safely accommodate the weight of the key ring. As is usually the case, the work will be done free of charge. The recalled vehicles include the 2000 to 2005 Cadillac Deville, 2004 to 2005 Buick Regal LS and GS, 2004 to 2011 Cadillac DTS, 2005 to 2009 Buick Lacrosse, 2006 to 2008 Chevrolet Monte Carlo, 2006 to 2011 Buick Lucerne and 2006 to 2014 Chevrolet Impala. Only the Impala is still in production, and even then, it's only sold to fleet companies.
According to an official statement from GM, there have been eight crashes and six injuries due to this latest issue. As if this isn't a dire enough blow for GM, the company has announced five smaller recalls, covering 165,000 vehicles.

Why GM will import the Cadillac CT6 PHEV from China

There's a clear-cut reason that General Motors is going to build its upcoming plug-in hybrid CT6 sedan in China. Sure, the car will be sold in China and the US, but the real reason for the "Made In China" stamp is environmental. If an automaker wants to build a new model in China, adding a green powertrain is an easy way to do that. The CT6 will have both a PHEV option as well as standard gas engine versions. David Leone, Cadillac's executive chief engineer, told AutoblogGreen recently that, "[China is] far more receptive to approving localized production of vehicle programs that have new energy vehicle powertrain applications." To put it succinctly, since the CT6 has a PHEV option, it is easier for GM to build all CT6 models in China. Some of them will then be imported to the US. "Most new global Cadillacs will also be produced in China as well. It's our second-largest market in the world." "To bring any new car into China, to produce it, you need government approval," Leone said. "The government isn't interested in bringing many new cars to market that don't have new energy credits. [The CT6] also provides new energy credits that enables it to be an attractive, well-received product in China." Leone said that there are two main markets for the various CT6 models: China and the US. The car will arrive in the 2017 model year, so some time after the end of June 2016. There are other practical reasons to build the PHEV in China, like the cells in the battery pack. Those are provided by LG Chem, which makes some cells in Michigan but more in South Korea. And GM already builds cars in China through its joint venture with SAIC, Shanghai General Motors, or SGM. "In February 2013 we started making the XTS, in summer of 2014 we started making the ATS-L," Leone said. "We will be producing [the CT6] within a number of months. Most new global Cadillacs will also be produced in China as well. It's our second-largest market in the world." The Chinese and US versions of the CT6 will be identical, Leone said. While some Cadillacs sold in China are slightly different than the US versions – the Chinese ATS is 77 millimeters longer, for example – the CTS6 PHEV will be exactly the same in both places, other than slight tweaks to the trim levels. Still, "more of our cars going forward will be the exact same car," he said. That doesn't mean that sales will be the same everywhere.

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
