GM cars and SUVs recalled for leaking transmission fluid

General Motors is recalling more than 194,000 vehicles from 2018 to 2020 due to transmission fluid leaks. The leaks stem from an auto stop-start component that may have been installed with loose or missing bolts. The leaking fluid can affect the transmission's performance, and if it leaks onto a hot exhaust component, could potentially cause a fire. GM says that to date, it knows of no accidents or injuries related to the defect. The issue affects models from all four GM divisions. From Chevrolet, the affected vehicles are: 2018 Malibu, 2018–2019 Cruze, 2018–2020 Equinox, 2018–2020 Traverse, 2019–2020 Blazer At Buick, the following models are included: 2018–2019 LaCrosse, 2019–2020 Encore, 2019–2020 Enclave, At GMC, the recall includes: 2018–2020 Terrain, 2019–2020 Acadia Cadillac has two affected vehicles: 2019–2020 XT4 and 2020 XT6 The recall is scheduled to begin in mid-December. Owners of the affected vehicles will be contacted. Dealers will inspect the transmission accumulator, and replace those with loose or missing bolts.

2022 GMC Hummer Edition 1 weighs 9,063 pounds

From the beginning, the Hummer line of vehicles has been synonymous with the phrase, "absolute unit." The M998 Humvee turned to civilian use as the Hummer H1 came with a curb weight of 7,560 pounds depending on configuration. The much more urbane Hummer H2 didn't sacrifice much of those gains, putting about 6,615 on the scales. Let us not forget that the behemoth gravitational pull and square-jawed mass were what every Hummer buyer wanted. So, starting with the brand values and customer demand, and adding the fact that electric vehicles are substantially heavier than their ICE counterparts, no one should be surprised that the 2022 GMC Hummer Edition 1 weighs 9,063 pounds. That's just one of the substantial figures GMC included in a self-certification filing submitted to the U.S. Environmental Protection Agency, the document rooted out by Car and Driver. Last year GMC told us the Hummer would weigh 9,046 pounds, which proves again the Freshman 15 (or 16) is unavoidable.  Loaded up with humans and their accessories, the truck's gross vehicle weight rating (GVWR) comes in at 10,550 pounds. It takes a few other big numbers to keep that kind of tonnage on the go. The Ultium battery weighs 2,923 pounds. With a 617-amp-hour capacity at 400 volts, total capacity comes in at 246.8 kWh, specific energy at 158 Wh/kg. Usable capacity is about 85% less, at 212.7 kWh. For the time being, these numbers put every other pack in a production vehicle in the shade. That gargantuan chemical plant in the Hummer's floor powers a 329-mile range the same way a giant fuel tanks feed a truck that gets 8 miles to the gallon. The miles per gallon equivalent figures GMC submitted to the EPA are 51 MPGe city, 43 MPGe highway, 47 MPGe combined. Motor Trend questioned whether GM applied the correction factor used for window sticker numbers; if not, the standard 0.7 correction drops the MPGe specs to 36 city, 30 highway, and 33 combined. However, trucks with a GVWR beyond 8,500 pounds don't need to display fuel economy figures on their window stickers, so don't expect to see any such details on dealer lots. For comparison, the Rivian R1T Launch Edition weighs about 7,000 pounds, and fits a 128.9 kWh battery good for an estimated 314 miles estimated at 70 MPGe.

Could the GMC Jimmy come back as a Wrangler fighter?

Every three or four years, two cars go into heavy media rotation in stories about supposed new competitors. The headlines go something like, "X automaker working on a vehicle to fight the iconic Y." The Y cars are the Porsche 911 and the Jeep Wrangler. For this story, the X automaker is GM. And since GM already has its 911-fighter poised for debut next month, we speak here of the Wrangler. Car and Driver writes that GMC might take another shot at a Jeep challenger, this time by rebirthing a body-on-frame Jimmy SUV. For any who don't know, GMC sold an S-15 Jimmy from 1982 to 2005, a twin of the Chevrolet S-10 Blazer. Those SUVs started their lives as the Chevrolet S-10 and GMC S-15/Sonoma pickups. The Blazer name has returned to the light, albeit without its old-school rugged manners. There's still an opening on the GMC side, though, so C/D says the idea would be to work that old magic on the GMC Canyon pickup. The report is more chaff than grist for the rumormill, with liberal application of phrases like "looking to come up with," "could be," "could take," and "could arrive." Having said that, a potential Jimmy model could come in a few years, could use the same six-cylinder gas and four-cylinder diesel engines as the Canyon, and could start around $30,000. The Jimmy could wear GMC's new mud-and-guts AT4 trim name, or become a mud-and-guts trim for the Canyon just as the ZR2 is for the Colorado. It's not an entirely crazy idea, however, when a body-on-frame Trailblazer SUV based on the Colorado sells in Latin America, Asia, and Australia and does pretty well in the mud and muck. GM's been on the edge of going to war with the Wrangler for at least 12 years, when a Hummer exec said the HX concept would debut at the 2008 Detroit Auto Show and go on sale in 2010 as the H4. In 2015, The Wall Street Journal said GM was canvassing GMC dealers about something to get in the ring with the Wrangler. And all that was before every other automaker had to watch Jeep open a money-counting operation to handle its Wrangler profits, and dealers started charging $20,000 markups on Gladiators. In May, spy shooters caught a sensor-laden Jeep running at GM's Milford Proving Grounds in Michigan. Earlier this month, Bloomberg reported GM is considering a Hummer revival as an all-electric hardcore SUV. So we will not be surprised if GM rolls out a Wrangler fighter in the near-ish future. But we won't be surprised if GM doesn't, either.
