GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.

Cadillac to add small sedan, crossover as part of major product blitz

Cadillac will add a small sedan and a compact crossover to its lineup in the next several years as part of an ambitious product blitz that will remake its lineup. The sedan will slot below the ATS, which is currently Cadillac's smallest four-door car. It's scheduled to arrive in 2017, Cadillac president Johan de Nysschen told Autoblog at the Detroit Auto Show. The sedan will be followed late that year or in early 2018 by a compact crossover, which will be positioned below the SRX. The crucial redesign of the SRX – Cadillac's top seller – arrives in 2016. It will switch to the brand's new naming system and change to an "XT" prefix followed by a number. The naming scheme debuts on the CT6, which launches in late 2015 and will be positioned above the CTS and XTS sedans. Cadillac also wants to add another crossover that sits between the SRX and its flagship SUV, the Escalade, at some point. Further out, Cadillac's long-awaited Mercedes-Benz S-Class fighter could arrive around 2020, and it would serve as the flagship or "showcase of the brand," de Nysschen said. Cadillac is also looking to expand its powertrain portfolio and is contemplating a wide range of options, including hybrids, plug-in electric vehicles and diesel engines. The new cars and crossovers are part of a $12-billion investment in Cadillac, which de Nysschen described as "an unheard level of capital" from General Motors. In total, the brand will receive eight new products through 2020. "Our product offensive will provide the substance for our ambitions," he said. De Nysschen has set high goals – and made major changes – at Cadillac since he took over the 113-year-old luxury brand in September. The brand moves to a separate headquarters in New York this year, away from GM's base in Detroit, and it has switched advertising agencies in a bid to elevate its image. Cadillac's sales declined 6.5 percent in the United States in 2014 to 170,750 units, and it has the smallest volume of GM's four brands. "Here in the US we continue to make progress, but we also face challenges," de Nysschen said. He added the brand's lineup "clearly limits our growth opportunities in the US market." Still, de Nysschen is taking the long view for Cadillac, noting it took years to turn around Audi, where he was president of its US operations for eight years. Cadillac's global sales have inched up five percent globally this year, spurred by a 47-percent surge in China.

Reuss says Cadillac CT6-based Buick could happen

Could the upcoming Cadillac CT6 and its Omega platform spawn a Buick variant? According to General Motors' product chief Mark Reuss, it could potentially be in the cards, but "not yet." "We're working on that," Reuss told Automotive News at the 2015 New York Auto Show. While there hasn't been a large, rear-drive Buick on dealerships since the Roadmaster in 1996, the company gave a big hint that it could head in that direction with the Avenir Concept, shown earlier this year at the Detroit Auto Show. As Automotive News explains, a rear-drive Omega-platform Buick could be a real hit in China, where consumers buy 13 Buicks for every one Cadillac. That move would be a big help to GM's bottom line, too, as it'd significantly increase the Omega platform's economy of scale. If a large Buick based on the CT6 were to head to China, though, it likely wouldn't be a simple case of badge engineering (thank God). Reuss hinted to Automotive News that while the mixed-material construction of the CT6 platform "is very flexible," doing an "identical version of that platform or not is a different conversation." What are your thoughts? Should Buick adopt the Omega platform for an Avenir-based sedan? Should that vehicle be sold here in the US, or should it be a China-only offering? Have your say in Comments.
