GMC reveals updated 2016 Sierra

It was just the other day that Chevy revealed the face of the new 2016 Silverado. And as might have been expected, sister brand GMC has followed up by unveiling its version in the facelifted 2016 Sierra pickup – just two and a half years since the current all-new model was rolled out. Though details released thus far remain few and far between, GMC has revealed more images of the new Sierra – in SLT, Denali and All Terrain trim levels – than Chevy did of the updated Silverado. It's got new headlights, fog lamps, and C-shaped daytime running lights and taillights, all using LED elements. It's arguably a more muscular look than the Chevy version, and with more chrome than the toned-down Silverado. That is, at least, in SLT and Denali trims. The All Terrain version looks more in line with the similarly off-road-focused Silverado Z71 and its color-keyed treatment. The changes ought to help GMC keep up the momentum that has seen its sales rise year-over-year every month over the past twelve. The interior shots indicate that the new Sierra will incorporate Apple CarPlay like GM is installing in so many models across its various brand ranges. But we'll have to wait a little while longer for all the details.

The new Sierra will be available in the fourth quarter of this year, with additional details and information on the new model released in the coming months.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.

Will GMC enter the subcompact crossover segment after all?

GMC last year categorically ruled out launching a subcompact crossover positioned below the Terrain, but the decade-old rumor refuses to die. The on-again, off-again model is back on track for production, according to a recent report. Citing anonymous sources, enthusiast website GM Authority claims the soft-roader is closer than ever to receiving the proverbial green light for production. It hasn't been approved yet, so development work hasn't started. What it will look like if it receives a thumbs-up from executives is up in the air, but GMC can take several paths into this lucrative (and increasingly popular) segment of America's new-car market. Chevrolet has two fighters in the ring: the Trailblazer and the Trax. GMC could feasibly choose one, put it in a brand-specific wrapper, and call it a day. It could also design its entry from scratch, though this option would take longer and cost significantly more. Either way, the model will allegedly be called Granite or Graphyte, and it will be positioned below the Terrain in terms of size and price, meaning it would likely start above $20,000. In 2019, GMC explained it ruled out expanding its range towards the bottom to position itself as a premium brand. It wanted to focus on high-profit models, like the Sierra and the Canyon, but the crossover's ever-increasing popularity may have proven too alluring to resist. Besides, small and premium aren't mutually exclusive, and downsizing would help the brand increase its annual sales. If you're experiencing deja vu, it's likely because we've heard murmurs about a city-friendly GMC since the Granite concept (pictured) made its debut during the 2010 edition of the Detroit Auto Show. It was approved for production that year, approved again in 2011 (tentatively on a Cruze platform), and abruptly canceled in 2012. GMC hasn't commented on the report, so we'll need to be patient to find out if it's accurate — and how it would differentiate its entry-level crossover from Buick's. In the meantime, the company is putting the final touches on the electric Hummer, which will be offered as a pickup and as an SUV, and it's about to unveil the 2022 Sierra.
