GM recalls 638,000 U.S. SUVs, trucks for unintended braking

WASHINGTON — General Motors is recalling 638,000 U.S. sport utility vehicles and pickup trucks because a wheel-speed sensor could fail and cause unintended braking, it said Thursday. The recall covers 2015-2020 Chevrolet Suburban, Tahoe, and Yukon and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. The sensor failure could result in unintended activation of the driveline protection system, and cause unintended braking of the wheel on the opposite side of the failed sensor. That could cause the vehicle to pull to one side unexpectedly, increasing the risk of a crash, the Detroit automaker said. GM said it was not aware of any crashes relating to the issue but found 150 field claims alleging the condition caused unintended braking or lateral vehicle motion. A GM dealer in May submitted a warranty report relating to the issue in a 2018 GMC Yukon, and two days later, a GM brand quality manager submitted the report to GMÂ’s Speak Up For Safety program that tracks potential safety issues, which prompted a GM investigation and testing.

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.

GM Design shows another early Hummer EV sketch

Like a new mother who's still so excited about her one-year-old baby that she can't stop showing ultrasound photos, General Motors is so excited about its biggest new baby, the battery-electric GMC Hummer, that it can't stop showing off development design sketches. The off-road monster with the 200-kWh Ultium battery pack debuted online on October 21 last year. The next day, the GM Design Instagram page posted some of the Hummer's early "theme sketches" leading to the production version. These had a conceptual flair to them, but were rather restrained. A month later, GM uncovered a series of development renderings showing off a much wilder truck bursting with more angles than a geometry text book. The archives have opened up again with a new "ideation sketch," this one between the first believable sketches and the second truck that Master Chief and Doomguy share on their days off.  All three sets of drawings show similar three-box proportions, it's the details that got a ton of love. On this newest sketch, the fenders flare a touch more than on the production truck, but the wheel wells are cut with the kind of clearance found on a Baja 1000 Trophy Truck. Out back, save for the tow hooks, the rear end is totally different than production. The sketch puts illuminated Hummer script across a narrow tailgate flanked by small square, taillights housing six individual elements. Beneath that, a bumper-less rear end puts nothing more than a sloped bash pate between the truck and the rocks it's just scrambled over. To our eyes, this is the best blend of production-ready comfort from the first sketches and zoot suit angles from the second that we've seen so far.  First deliveries of the GMC Hummer EV Edition 1 are expected before the year is out. When we get a chance to absorb the truck in its native habitats, we'll know whether there's cause for disappointment at what could have been. If so, with all this hunger among the monied for something different, we feel like restomodders have been given the perfect head starts on custom rebodied Hummers that would make things right.
