GM recalls 3,300 pickups and SUVs for new ignition-switch issue [UPDATE]

UPDATE: A statement from GM about the recall has been added below. The exact total of vehicles affected is 3,296, including 3,073 of them in the US. General Motors isn't letting an ignition-switch problem grow into a massive scandal again. The automaker is recalling about 3,300 North American trucks and SUVs. They are: the 2014 Chevrolet Silverado and GMC Sierra and the 2015 Chevy Suburban and Chevy Tahoe, as well as 2015 model heavy-duty pickups, the Detroit News reports, citing an Associated Press story. The issue appears to have been caught fairly quickly. In this case, the keys can get stuck in the "start" position and then slip to "accessory" if bumped. This is because the ignition lock gears have an outer diameter that's larger than the specifications allow. When that happens the engine shuts off, and the driver loses assistance to the steering and brakes. The airbags might also be affected. The vehicles get a new ignition-lock housing to fix the problem. According to the Detroit News, an employee who experienced the problem with the switch discovered the issue, and this person then let officials at the automaker know as part of the Speak Up for Safety program. A total of five reports of the fault were discovered. However, there are no cases of injuries or crashes. The claims to the automaker's resolution program eventually tallied that GM's previous ignition switch problem included 124 deaths and 275 injuries. The company also had to recall millions of vehicles and pay significant fines to the US government. GM Statement General Motors is recalling 3,073 full-size trucks from the 2014 and 2015 model years in the U.S. Some of these vehicles may have an ignition lock actuator gear with an outer diameter that exceeds specifications, which may make turning the ignition key difficult. The ignition key could get stuck in the "start" position. This may be more likely at higher interior ambient temperatures. If the vehicle is driven with the key stuck in the "start" position, and the vehicle experiences a significant jarring event or the vehicle's interior temperature cools, the ignition lock cylinder could move out of the "start" position, rotate past the "run" position, and move into the "accessory" position, leading to loss of power steering assist, power brakes and potentially air bag deployment in certain crashes. Dealers will replace the ignition lock housing.

2021 Jeep Grand Cherokee L vs Big Three-Row Crossovers | Spec comparison

The three-row 2021 Jeep Grand Cherokee L is here, entering an ever-growing segment of big crossovers that Jeep has ignored since the Commander of the late 2000s. Of course, the Dodge Durango has basically been a three-row version of the current Grand Cherokee with Dodge styling and a different interior, so it's not like The Corporate Entity Formerly Known as Chrysler has been without a contender in the segment. Jeep is a stronger brand than Dodge, however, and the three-row midsize segment is stronger than those with two rows (there's a vast sales difference between the Chevrolet Traverse and Blazer, as well as the Honda Pilot and Passport). In other words, the Grand Cherokee L could be a very big deal. It is also, quite literally, a very big deal. As you're about to see, it is now the largest three-row crossover, besting the length, wheelbase and height of even the gargantuan Traverse. There's more to the story than that, however, so we put together the below comparison chart to show you how the new Grand Cherokee L lines up on paper versus the biggest three-row crossovers. That includes the 2021 Ford Explorer, 2021 Kia Telluride, 2021 Hyundai Palisade and 2022 Chevrolet Traverse. This group also represents some of the strongest entries in the segment as well as those we feel are most likely to be considered alongside the big Jeep. To that end, we also included the 2021 Lincoln Aviator in the chart since its base price is actually less than what we anticipate the luxurious, range-topping Grand Cherokee L Overland and Summit trim levels to start.  Engines and drivetrains Note the differences in curb weight here. The Grand Cherokee L has the highest base curb weight of the group apart from the high-lux Aviator, yet its 3.6-liter V6 has the least amount of power and torque. Therefore, it'll be surprising if it's not the slowest in the group. There's of course the Hemi V8 available on the top Overland and Summit trim levels, but again, a hefty curb weight works against it. At 5,330 pounds, the lightest V8-powered JGCL weighs 600 pounds more than V6-power Explorer Platinum and ST models. On the other hand, nothing can touch the Hemi Jeep's towing capacity, and only the 400-hp Aviator betters the Jeep's base V6. Its 6,200-pound towing capacity greatly outdoes the 5,000-pound limits of not only the Telluride, Palisade and Traverse, but most others in the segment as well.

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.
