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.

Buick Velite Plug-In Hybrid Concept debuts to little fanfare

Buick pulled the covers off its latest Velite Concept at the Auto Guangzhou 2016 show in China. We say latest because this is actually the second time Buick has used the Velite name for a concept, the previous having been shown at the 2004 New York Auto Show. The first Velite concept was a two-door convertible; the second Velite is a four-door crossover. Enough about the name, what about the concept? Well, it's very highly stylized, and we don't really mean that in a good way. There's nothing about the Velite that screams Buick, except for its badges, of course. At the front is a compressed version of Buick's traditional waterfall-like fascia. It's flanked by slit-like LED lighting elements. The rest of the face looks to our eyes like it draws inspiration from the latest Toyota Prius. There isn't a single flat element to the Velite Concept's bodysides, in a way that resembles recent concepts from Infiniti. The last bit of styling flourish are deep recesses just ahead of the rear wheels, a look that is reminiscent of BMW's i-series of vehicles. There aren't any images showing the Velite's hind quarters, but from what we can see, that also has a QX-ish look about it. There are no shots yet of the Velite's interior, but Buick says it's "elegant" and "includes recycled materials." We wish we could see what it looks like, because the automaker says it "[points] to design trends for upcoming new energy vehicles." So, the Buick Velite Concept is a nondescript mashup of design elements that we've already seen. Under the skin, however, things are more interesting. It's a plug-in hybrid with a modular lithium ion battery. That doesn't tell us much – it could be a variant of the Chevy Volt, or it could be a different system altogether. We look forward to finding out. In the meantime, have a look at the high-res image gallery up above. Oh, and if you're wondering, the word velite traces its roots back to a lightly armored military division in ancient Rome. Related Video:

GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:
