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.

GM SUV window switch recall urges owners to park vehicles outside

It's not unusual for there to be a lag between an automaker announcing a recall and the official documentation showing up on the National Highway Traffic Safety Administration website. So it's no surprise that a recent GM campaign took about a month to appear in its official capacity. However, there appears to be some big differences between the two reports with potential safety implications.
In late June, GM announced that it needed to recall 181,984 examples of the Chevrolet Trailblazer, Buick Rainier, GMC Envoy, Isuzu Ascender and Saab 9-7x from the 2005-2007 model years, plus the 2006 Chevy Trailblazer EXT and 2006 GMC Envoy XL. The new documents paint a slightly different picture with 184,611 needing repaired and different model years listed.
The reason for the fix is still the same, though. It's possible for fluid to contact the master power window switch module in the driver's door, which can corrode the part. Eventually this could cause a short circuit, leaving the buttons inoperable and potentially leading to a fire. But the new NHTSA documents add an important note: "A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made."
