GM recalls select Tahoes, Yukons, Escalades for rear driveshaft issue

GM is recalling a number of its full-size SUVs due to an issue with the rear driveshaft assembly that could ultimately result in driveshaft failure. The actual number of total vehicles involved in the recall is small at just 1,789, but it’s spread out across the entire 2021 model year full-size GM vehicle lineup. That means a small number of every model is being recalled, including the Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL and the Cadillac Escalade and Escalade ESV. GM traced the issue back to certain driveshaft assemblies with ball bearings that were not properly heat treated. If theyÂ’re not properly heat treated, GM says that the balls may deform over time, causing noise and vibration. Continue to drive in this condition, and GM says the affected joint in the driveshaft assembly could seize, causing loss of drive power. However, the problem wonÂ’t present itself all at once, as GM says there will be a gradual increase of noises and vibrations before total failure. For those few owners with affected vehicles, GM says that it will replace the left and right rear driveshaft assemblies with properly-built units. Per usual with recalls, this will be done at your local dealership at no cost to the owner. If you have one of the recalled SUVs, expect to be notified mid-March. Related video:

2016 Chevy Volt powertrain video teasers

If there's one thing we've learned about plug-in vehicle fans, you have a thing for seeing your cars get made. The series of videos showing BMW i3 production was strangely popular, as were the shots from inside the VW e-Golf plant. Well, with General Motors pulling the veil off of the 2016 Chevy Volt this week, it's time to take a peek at the production process for that vehicle as well. You're welcome. Up first we've got a clip from CNN Money showing a little bit about how the new Volt's new battery pack and other powertrain components are made. Those of you who are trying to read the lithium tea leaves and see if the new shape reveals that the 2016 Volt will have five seats might want to check it out. Then we've got two clips from GM itself, one showing an animation about the updated Voltec powertrain and another with some B Roll of the old Volt. Since GM doesn't want us to see the new car quite yet, we'll have to enjoy this for now. Watch below. This content is hosted by a third party. To view it, please update your privacy preferences.

GM to sink over $900M into 4 plants, mostly for a new V8

FLINT, Mich. — General Motors says it will spend more than $900 million to update four factories, with the bulk going to an engine plant in Flint, Michigan, to build the next-generation V8 for big pickup trucks and SUVs. Factories in Rochester, New York; Defiance, Ohio; and Bay City, Michigan, also will see investments, some to make V8 engine components as well as parts for future electric vehicles, the company said Friday. The investments won't create any new jobs, but they will preserve about 2,400 hourly and salaried positions positions at the four sites, the company said. The investments “provide job security at these plants for years to come,” Gerald Johnson, GM's manufacturing chief, said in a statement. Much of the money, $579 million, will go to Flint Engine Operations for equipment to build the sixth-generation small-block V8 that will go into the next round of big pickup trucks and SUVs. The plant now employs about 700 people who also will keep making their current product, a diesel engine used in light trucks. GM, like other automakers, is facing stricter government fuel economy standards and pollution limits starting in the 2024 model year. New vehicles sold in the U.S. will have to average at least 40 miles per gallon of gasoline in 2026, up from about 28 mpg, under new Biden administration rules that undo a rollback of standards enacted under former President Donald Trump. That means the new V8 will have to get better mileage and pollute less than the current versions. Although GM wouldn't release details on the new engine, Johnson said during a news conference at the Flint plant that it would be more efficient than the current version. GM has a goal of selling only electric passenger vehicles by 2035, but Johnson said that's a dozen years out, a period when many customers will still want gas engines. “We know that has a horizon,” he said. “Between here and there, there are a lot of internal combustion customers that we don't want to lose,” he said. In addition to Flint, GM's engine components plant in Bay City, Michigan, will get $216 million to build camshafts and connecting rods, and to machine engine blocks and heads for the new V8 being built in Flint. The plant now employs about 425. The Defiance, Ohio, foundry will get $55 million to build a variety of block castings for the new V8. Included is $8 million for castings to support future electric vehicles, the company said. The plant has about 530 employees.
