GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.

Despite strong profits, GM still fighting flat market share

Looking at the progress General Motors has made since it entered bankruptcy, it's easy to forget that the company still has a long way to go before it's the juggernaut it once was. A recent report from Reuters points out that, while GM is making money, it isn't making any gains in terms of US market share. Quite the opposite, really. Consider this factoid: In 1963, nearly half of the cars sold in the United States were from Chevrolet, Cadillac, Buick, GMC or Pontiac. Now, the company's US market share is stagnant at 17.9 percent. That same number is half of just Chevy's 1963 market share. This is all despite GM going on a binge replacing or updating its models. "Market share increases are not instantaneous," Mark Reuss told Reuters at the 2014 Detroit Auto Show. "We've got a lot of baggage. Don't underestimate what people though of us, or these brands, through these hardships and 30 years." The reasons for the stagnant market share are numerous. Reuters points out that retooling of factories and a focus on limiting incentives are both good things for profit, but not necessarily for market share. There's also the troubling turnover of the brand's marketing department. These issues don't change the fact that Chevrolet has lost 1.4 percent of its market share in two years, and that Cadillac - arguably GM's most improved brand overall - has lost 1.2 percent in the same period. Part of that can be blamed on GM's avoidance of fleet sales in favor of more profitable customer sales. "Our focus has really been on retail and that's where we've got the growth," said Alan Batey, GM's interim global marketing boss. "We want to grow GM and that means growing market share and profits, but it's not at all costs," Reuss said.
