GM recalls 8,500 Chevrolet Malibu models for rear suspension glitch

According to a letter from General Motors to the National Highway Traffic Safety Administration, flaws in the build process of the 2013 Chevrolet Malibu have led to the recall of 8,519 cars. Units built between December 6, 2011 and January 15, 2013 may have been assembled with rear suspension cradles that had insufficient torque applied to certain bolts. That out-of-spec assembly could lead to issues ranging from slight noises to a loss of vehicle control.
The problem was first noticed in December of last year by a GM test fleet driver and eventually tracked back to the improperly torqued bolts on the suspension cradle assembled through July 2012 by a supplier located not too far from the Malibu's Detroit/Hamtramck Assembly Plant. Since an official NHTSA recall notice has not been issued yet, it isn't clear whether or not Detroit-built Malibus were the only ones affected (the 2013 Malibu is also built at GM's Fairfax Assembly Plant in Kansas City, Kansas). Dealers will fix the problem by inspecting vehicles for proper torque specs, retightening if not within specs and, in some cases, perform a rear-wheel alignment.

Nissan Leaf, Chevy Volt sales both down in June

The best news you can slice out of today's sales reports for June 2015 is that things have to get better at some point. Most likely, sales of the Nissan Leaf and the Chevy Volt will see a big increase once the second-generation models of both vehicles arrive (the Volt later this year and the Leaf, well, at some point after that). For now, though, the best-selling EVs in the US are both suffering compared to where the numbers were at last year. The numbers are also suffering compared to last month, which was the best of the year so far for both vehicles. Looking just at June, though, Leaf sales totaled 2,074 units, down 11.6 percent from a year ago (the EV sold 2,347 units in June 2014). The world's best-selling EV is now down 22.9 percent for the year so far (12,736 in 2014 vs. 9,816 in 2015). Things are a bit worse over at Chevy, where news about the pretty-much-better-in-all-ways second-gen Volt is coming out with great frequency. Nonetheless, people are still buying the outgoing Volt, snapping up 1,225 units in June. That's down 31.1 percent from the 1,777 sold in June 2014. So far in 2015, the Chevy has sold 5,622 Volts, a drop of 34.7 percent from the 8,615 Volts sold in the first six months of 2014. As always, we're working on our full tally of green car sales for June and will bring that to you shortly. For now, discuss the sales of these two plug-in pioneers in our Comments, below.

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.
