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.

GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.

2018 GMC Sierra Denali can help you tow without breaking a sweat

Towing a trailer once meant that only those who possessed certain knowledge would be able to go fishing, tow a race car or pull a camper safely. For me, it took four long years of practice working a job behind the wheel of a jacked-up Ford F-250, hauling tons upon tons of mowing equipment for my local parks department, to become proficient. Just how far things have come since then became evident after a recent trip to Utah with GMC, in which we used the half-ton Sierra Denali to tow a set of Polaris side-by-sides through the state. Modern safety technology and a suite of electronic aids make towing simple enough that anyone with a driver's license and something to haul can do it. This revelation came behind the leather-wrapped and heated steering wheel of GMC's outgoing 2018 Sierra Denali. Sitting in the plush, heated and cooled captain's chair, I could barely feel the 6,000 pounds I was towing behind me. Even GMC's smallest full-size truck engine, a 5.3-liter V8 generating 355 horsepower and 383 lb-ft of torque, felt like overkill for what used to amount to a heavy load. With Utah's pristine landscape, the plush confines of the cabin and the uneventful nature of modern towing, mile after mile just streamed by at highway speeds without incident (or excitement). When we finally reached our destination a few hours later, one of GMC's representatives who had chosen to sit in the rear of the cab asked me what I thought about the drive. I pondered for a few minutes and answered with this: "Modern pickup trucks have removed nearly every skill-based variable once associated with towing. I could drive this truck and trailer confidently with just one finger." Consider the near overabundance of towing-assistance systems in the GMC Sierra Denali that I piloted through Utah. Let's start with the most basic of towing skills — something that's now been relegated to the annals of history: reversing a pickup to meet the trailer's hitch. Once upon a time, this required knowing a truck's dimensions and understanding proximity, as well as having a keen eye, a steady foot for both the gas and the brake and the patience to get it right. Now, though, pickups such as the Sierra Denali offer customers a trailer reverse camera system that helps the driver align truck to hitch with pinpoint accuracy.
