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.

GM recalls nearly 1 million vehicles for airbag defect

WASHINGTON — General Motors said on Friday it will recall nearly 1 million sport utility vehicles in the United States because the driver's airbag inflator may explode during deployment. The recall covers 994,763 Buick Enclave, Chevrolet Traverse, and GMC Acadia vehicles from the 2014 through 2017 model years with modules produced by ARC Automotive Inc. Dealers will replace the driver's airbag module. The National Highway Traffic Safety Administration said a driver in Michigan of a 2017 Chevrolet Traverse was in a crash in which the front-driver airbag inflator ruptured during deployment causing facial injuries. An April 25 inspection confirmed that the front driver airbag inflator ruptured in the vehicle. The National Highway Traffic Safety Administration (NHTSA) demanded the recall of 67 million air bag inflators because it believes there is a safety defect, but auto supplier ARC Automotive Inc rejected the U.S. regulator's request, documents released on Friday show. The auto safety agency said the inflators pose an unreasonable risk of death or injury. Even as ruptures mount, "ARC has not made a defect determination that would require a recall of this population," NHTSA said in its demand letter to the Tennessee-based company. "Air bag inflators that project metal fragments into vehicle occupants, rather than properly inflating the attached air bag, create an unreasonable risk of death and injury." GM said it was still investigating the issue with the assistance of a third-party engineering firm. "GM is taking this expanded field action out of an abundance of caution and with the safety of our customers as our highest priority," the Detroit automaker said. GM said it was aware of two prior ruptures of ARC-manufactured airbag inflators in 2015 Chevrolet Traverse vehicles, and GM conducted two earlier small recalls of about 3,000 ARC inflators. All three rupture events in Chevrolet Traverse vehicles involved the same inflator variant. ARC noted in a letter made public Friday that no root cause for those ruptures has been identified by ARC or GM. ARC said it was assessing the scope of GMÂ’s recall.  Government/Legal Recalls Buick Chevrolet GMC Safety Crossover SUV

Next-gen GMC Terrain teased looking chiseled in AT4 trim

The next-generation GMC Terrain is coming soon, as GMC just dropped its first teaser of the redesigned compact crossover. It makes sense that GMC is re-doing the Terrain now, as its Bowtie-badged equivalent, the Chevrolet Equinox, was just completely redesigned, too. GMC teased the new Terrain in its most rugged AT4 trim, and the look sure is a bold one from this partial front-end view. From the headlights to the upright grille and chiseled hood, this Terrain is looking more Yukon- and truck-like than ever before. Expect the AT4 version seen here to mirror the Equinox Activ trim from an equipment perspective by adding all-terrain tires wrapping smaller-diameter wheels for a legit boost off-road. It may also feature a unique front bumper for improved approach angle. As for the interior, spy photos have shown that it will differ significantly from its Chevy cousin. Those photos show a tall, vertically-oriented screen that takes its cues from the GMC Acadia. There isn’t much in the way of details provided by GMC, but the company does let on that the new Terrain – this will be its third generation – will have a “bolder, more assertive design” throughout the vehicle. Based on the Equinox, we're expecting it to get the same turbocharged 1.5-liter four-cylinder with 175 horsepower and an eight-speed automatic transmission. All-wheel and front-wheel drivetrains will likely be offered as well. A full reveal isnÂ’t planned until “later this year,” leading us to believe this Terrain will be a 2025 model year vehicle just like the Equinox is. ItÂ’s also scheduled to launch after the refreshed Yukon, which GMC says is coming along later this year, too. Related video:
