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 recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

March Madness upsets good for auto advertisers

There are no Cinderella teams left in the NCAA men's basketball tournament - the fairytales ended with Georgia State's loss to Xavier over the weekend. And even though the Sweet 16 is composed of elite teams - at the time of writing the lowest-ranked squad is 11th-seeded UCLA, which has most championships of any school in the country - there are still underdogs and surprises, and they are good for NCAA business and advertisers. Last year the March Madness Live app, which allows users to watch games on the go, was downloaded 4.5 million times, a jump of more than 40 percent over 2013. Buick sponsors the iOS version of the app, but more than a million of those downloads were for the Android version, sponsored by Infiniti since 2011. Part of Buick's engagement is a "Boss Button" on the livestream sites that can quickly mask the page with something your boss won't question you over. It also sponsors a trick-shot competition for fans, has a display in Bracket Town during the Final Four, and its cars lead the team buses through the city. Infiniti said last year's tourney increased online searches for the brand by 25 percent in March, and things are going even better this year: it's round-by-round bracket game drew 477,859 total entries in 2014, this year's game has signed up 534,350 already and the tournament has another two weeks to go. The luxury brand is all over the event, promoting the QX60 through to the Final Four, then moving its efforts to the Q50. It sponsors the Coaches vs. Cancer charity and will have an Infiniti Lounge near the Final Four venue in downtown Indianapolis. So for the two automakers keeping their own scores... come on, Wichita State! Six brackets, six chances to win a trip to #FinalFour 2016.
