GM recalls 51k Enclave, Traverse, Acadia crossovers over fuel gauge inaccuracy

With all eyes fixed on General Motors in the wake of the ignition recall debacle, the auto giant has been carefully calling in a wide array of vehicles to fix anything and everything that could prove problematic. Just the other day it issued two separate recalls - one concerning the Cadillac SRX and another its heavy-duty pickups - and now it is issuing another.
This time the vehicles in question are the Buick Enclave, Chevy Traverse and GMC Acadia, three fullsize crossovers based on GM's Lambda platform. In an estimated 51,640 units manufactured between March 26 and August 15, 2013, the engine control module has been found to incorrectly display the level of fuel in the tank.
As a result, owners are being notified to bring their vehicles in to their local dealers to have the ECU reflashed to fix the problem. View the full details in the announcement below from the National Highway Traffic Safety Administration.

2018 GMC Acadia with 'Christmas Aero' modification gets in the wind tunnel

Tis the season of "Big" - big cheer, big parties, big bowls of eggnog, big decorations, and when it comes to your family hauler, big drag. Festive drivers who festoon their crossovers, minivans, and SUVs with wreaths, Rudolph noses, fuzzy antlers, and rooftop Christmas trees undo the years of work that car engineers devote to fractional gains in fuel economy. To put numbers to such fuel-guzzling madness, GMC started with a 2018 Acadia, optioned it with the Xmas Aero Package - both Standard and Plus versions - put it in Lockheed-Martin's wind tunnel. The resulting dip in fuel economy results probably won't surprise anyone who's used a roof rack - or, for that matter, their car's air conditioning. However, it might surprise you to find out which seemingly substantial decoration had no effect, and which seemingly innocuous decoration was about twice as bad as running the A/C on its Mr. Freeze setting. Check out the brief video above for the results. And consider placement of that bow carefully.

2014 Chevy Silverado, GMC Sierra first pickups to ace updated NHTSA tests [w/video]

General Motors has just become the first pickup truck manufacturer to receive five-star overall vehicle scores in the National Highway Traffic Safety Administration's New Car Assessment Program. The updated safety standards, which went into effect in 2011, are more strenuous than the previous NHTSA curriculum and involve collecting both more and more substantial data, reflecting the improved safety inherent in newer vehicles. This feat is made more impressive by the fact that both Ford and Ram have released brand-new trucks since the new testing went into effect - GM's victory is no technicality.
The rating only applies to the redesigned, light-duty Silverado, Sierra and their upmarket variants, High Country and Denali, respectively, while only Crew Cab variants were tested. Considering that the four-door body style will make up 60 percent of GM's light-duty truck sales, the exclusion of the other variants seems reasonable.
This news is sure to be yet another feather in GM's pickup-oriented cap. Be sure to scroll down for video of the crash testing, as well as the full press release from General Motors.
