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:

More than half of Mazdas sold in 2018 are CX-5s, and other interesting sales facts

Last year was a seriously good year for carmakers. Overall, more vehicles were sold than in 2017, and the total number wasn't far off of the all-time record in 2016. Digging deeper into the numbers, you'll find some pretty usual stuff including the Ford F-Series still being the bestselling pickup truck in America, and a continued trend toward crossovers. But there are also some oddball factoids tucked in these sales reports, some that defy the trends, and some that are extremes of the public's buying preferences. We've compiled several interesting tidbits from last year's sales right here for your enjoyment. More than half of Mazda's sales were of CX-5s Yes, over half of all Mazda sales were of this one model. The company sold 300,325 cars in America last year, and 150,622 of them were CX-5 crossovers, or 50.1 percent. Just for emphasis, that means the other 49.8 percent of Mazda's sales were split among five other models, the Miata, 3, 6, CX-3 and CX-9. Breaking that down further, the second-best seller was the Mazda3 at 64,638, which isn't even half of the CX-5's sales. People are crazy for Mazda's middle crossover. Volkswagen actually sold more cars than crossovers It's clear that the crossover is the future king of car sales. For most mainstream brands, it already is. Chevy, Ford, Honda, Toyota, Subaru, Mazda and Nissan all sold more crossovers and SUVs than they did conventional sedans and hatchbacks. There are holdouts, though, and one of them is Volkswagen. At the end of 2018, the company sold 189,343 cars and 164,721 crossovers in the U.S. So that's one win for the classic car set, and it's justification for VW to maintain its car line for the foreseeable future. It's a bit of a hollow victory, though. Look closer and you'll see that car sales were down 28 percent from 2017, when VW sold 262,029 cars. Crossovers, on the other hand, jumped 112 percent from 2017 when 77,647 crossovers moved through U.S. dealers. So expect the tables to turn very soon. Mustang is still the muscle-car sales king, but Challenger is the only one to improve Once again, the Ford Mustang topped the muscle-car sales charts, beating out the Dodge Challenger and Chevy Camaro. Ford moved 75,842 of the ponies in 2018, while Dodge sold 66,716 Challengers for second place, and Chevy sold 50,963 Camaros to bring up the rear.

Recharge Wrap-up: Range-extended EV taxis in London, 2016 Chevy Volt interior two years old

The first Metrocab range-extended EV taxis are operating on the streets of London. The cabs use a 12.2-kWh battery and two 50-kW motors, as well as a 1.0-liter gasoline range extender. Fuel economy is 98 MPGe on the ECE101 cycle, and total driving range is over 348 miles before needing to charge or refuel. Cabbies can expect to save GBP20 to GBP40 (about $30 to $60) per day on average. "The cash savings on fuel are significant, the ride and comfort outstanding, and my first customers are thrilled with the new cab," says the first operator of the new EV taxi, Preston Morris. "With its air suspension providing unrivaled comfort, panoramic glass roof for views of the city and silent powertrain, what's not to like?" Read more in the press release below. Chevrolet has had the interior design of the 2016 Volt finished for two years already, according to GM interior designer John McDougall. Beginning around 2010, GM received sketches from designers worldwide before narrowing it down to a handful of designs. Then the top three choices were molded from clay. The chosen theme was then refined for up to 18 months. "Every little thing you can imagine goes into that," says McDougall. "The glare angle from the windows, the placement of the controls, the placement of the seat. You have to create something that's beautiful and functional."

Vattenfall has announced a research project in partnership with BMW and Bosch to use retired EV batteries for stationary, grid-connected energy storage in Hamburg, Germany. Over 100 lithium-ion batteries from BMW i3 and ActiveE vehicles will make up a two-mWh storage unit for grid balancing, enough to power 30 four-person households for a week. The system is "compact enough to fit in a small building," says Bosch. Such storage systems are especially fit for storing and moving alternative forms of energy, which often fluctuate in supply more than electricity from a traditional power plant. Vattenhall will operate the storage unit for 10 years, with Bosch managing the batteries, during which time the three partners hope to learn more about battery applications and their performance over time.
