GM's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.

2020 GMC Sierra HD caught in double-cab, low-trim gas-engine guise

Naturally when the 2020 GMC Sierra HD was revealed, GMC picked the flashiest, most-impressive Denali model with the big crew cab configuration and diesel engine. But obviously not all will be equipped that way, so it's exciting to see a lower trim model like the truck above. This 2020 GMC Sierra HD is a more modest SLT trim model equipped with the gas V8 and lacking the MultiPro tailgate. Styling doesn't take a hit with the shorter shape, and arguably, it looks more athletic without so much metal between the wheels. The length is the only real difference, with the rest of the sheetmetal just as chisled on the bigger version. Interestingly, this gas-powered Sierra HD still has a big hood scoop from its diesel sibling. On the current GM heavy duty trucks, only the diesel models get a scoop, and it's specifically for getting more cool air to the intake. The Silverado HD may continue this differentiation, but GMC is clearly keeping it for all models. When the Sierra HD goes on sale this summer, it will be available with either a 6.2-liter gasoline V8 like in this truck, or a 6.6-liter turbodiesel V8 making 445 horsepower and 910 pound-feet of torque, the same as the current model. All models get bedside steps, and the MultiPro tailgate is available either as standard or an option with all trims. Related Video: This content is hosted by a third party.

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."
