GM planning to put its fullsize pickups on a big diet, too

General Motors is just coming off a complete redesign of the Chevrolet Silverado and GMC Sierra for 2014, but in the US fullsize truck market, there is no rest for the weary. According to Reuters, plans are already unfurling for both trucks to drop pounds from their curb weight over the next few years, but this will unlikely be able to keep pace with the 700-pound diet targeted for the next-generation Ford F-150, a truck expected to debut late next year.
The biggest weight reduction for these trucks might not be available until the next full redesign, which will likely happen around 2019, but the article says that smaller updates could shave pounds in the meantime. Two examples given include an "aluminum-intensive" version of the Silverado that could shed 250 pounds and debut around the same time as the lighter-weight, aluminum-bodied 2015 Ford, and there is also talk of reducing weight for driveline components such as axles and driveshafts. These changes are all part of an attempt to meet strict new fuel economy standards coming in 2017, targets which will get even tougher in 2025.

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."

2015 GMC Canyon

As discussed earlier today, the 2015 Chevrolet Colorado is a new standout in terms of midsize trucks. But the Colorado wasn't the only pickup the General Motors team brought to San Diego for us to sample. Also along for the ride was a pack of GMC Canyons, the slightly more expensive and polished platform-mate to the Chevy.
There's no question that the Canyon and the Colorado are a lot alike under the skin - almost entirely, in fact - so GMC has worked to first create some daylight between the two trucks by way of sheetmetal. This is most obvious from the front view, where the blocky and blingy GMC grille replaces the more subdued tone and shape seen on the Chevy's nose. Projector headlights with LED running lights come as standard, and, again, with the squared-off look that is typical of the brand. 16-inch aluminum wheels come stock on the GMC, too, with the 17-inchers seen on my photo truck offered as standard equipment on the top-trim SLT.
GMC considers the Canyon to be the only premium truck in the segment (which is clearly true), and the team has spent a ton of time and effort to get the interior correct to prove out that point. "Any trim that looks like metal, is metal," I was told at the product briefing, a certain indication that the company is serious about bringing a new class of buyer to a truck segment that it hopes to redefine.
