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.

2014 Chevy Cruze Diesel destined for Chicago debut

It's been a little over a year and a half since General Motors first confirmed plans to offer a diesel-powered Chevrolet Cruze here in the United States, and we've now learned that the oil-burning compact will debut under the lights of the Chicago Auto Show in February. According to GM Authority, the Cruze Eco-D will be introduced as part of the entire 2014 model year Cruze range, set to go on sale in the second quarter of this year.
Earlier reports have indicated that the diesel Cruze will be able to achieve fuel economy numbers in the range of 50 miles per gallon. For comparison, the similarly sized Volkswagen Jetta TDI is rated at 30/42 mpg city/highway, but as we found out in our long-term test of the 2011 model, hitting 50 mpg was a piece of cake.
Official specifications will be released at the time of the 2014 Cruze's unveiling, though reports have stated that the sedan will be powered by a reworked version of the 2.0-liter turbo-diesel inline-four found in the Holden Cruze CDX overseas. In that application, the four-pot oil-burner produces 160 horsepower and 265 pound-feet of torque - increases of 20 hp and 29 lb-ft over the 2.0-liter engine used in VW's Jetta TDI.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.
