GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

Recharge Wrap-up: Chevy Volt class action suit proposed, Tesla stock could outperform in 2015

A class action suit has been proposed against General Motors for a steering problem in the Chevrolet Volt. The plaintiffs claim that a defect can cause the steering to freeze intermittently, and that General Motors either knows or should have known about the problem. The case, filed in New Jersey, also claims that defective parts are replaced with the same or similar parts, which are also defective. The plaintiffs say that claims for the 100-plus-member class exceed $5 million. Read more at Law360 or at BigClassAction. Tesla Motors stock (TSLA) has risen after weeks of losses. It gained 5.4 percent during the week ending December 19, when it closed at $219.29 per share. Since then, it rose slightly more, closing at $222.26 on December 24. Morgan Stanley lowered its target price on Tesla stock from $320 to $290, predicting lower sales on the upcoming Model III than expected before, but still called Tesla a good long-term investment. Analysts at CNBC predicted Tesla to be the best performing stock of 2015. Read more at ETF Daily News. Oslo- and New York-based architecture firm Snohetta has designed a zero-emissions house that also charges an electric car. The ZEB Pilot House, built in Larvik, Norway, uses a solar panel on the roof to power the house, which also provides enough excess energy to charge an EV. To make the most of energy most efficiently, the house uses smart technology to use as much energy as it can once it's harvested. This means one can turn on appliances like the washing machine remotely while the sun is at the optimum angle in the sky - perhaps during mid-day when the residents are at work. The house also uses organic materials and is designed to save as much energy as possible. Read more at Wired.
