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:

Chevy working on production Impala Midnight Edition

To put together the Impala Blackout concept for SEMA, Chevrolet didn't need to go much further than its accessories catalog. The in-house connection is what could make it possible for Chevy to get a production version of the Blackout into dealers this model year, with its few bits of chrome trim and dark detailing on the 19-inch aluminum wheels set into an abyss of gloss black paint, black Bowtie, grille surround, rear spoiler and mirror caps. The interior is black leather, with stainless steel for the sill plates and pedals, and an 11-speaker Bose audio system, and it gets the optional 305-horsepower, 3.6-liter V6. The brand's marketing director for cars and crossovers, Steve Majoros, told Edmunds that it could come in late spring, and that it will be called "Midnight Edition." Majoros didn't give any indication of pricing or if the production car will be spec'd out like the concept. If you simply don't want to wait for late spring, you could work your DIY mojo by putting one together the same way Chevrolet did: give the accessories catalog a workout. Related Video:

2016 Chevy Volt will not need premium gas

Buried in the new technical details of the 2016 Chevy Volt released yesterday was a throwaway line about a small but important change that's due to the new 1.5-liter, four-cylinder engine. The first-gen Volt has always required premium gas but the new powerplant will be happy burning plain old regular. The Volt's chief engineer, Andrew Farah, told AutoblogGreen that the change was due to today's Volt owners explaining they were not happy paying for top-shelf petroleum. "The ability to use regular unleaded was based directly on customer feedback," he said. "Since the range extender is an all-new engine, it was optimized to use regular unleaded at the outset. Using regular fuel will not have effect on vehicle acceleration or other performance factors." As Larry Nitz, GM's executive director of vehicle electrification, told AutoblogGreen yesterday, the new engine is more powerful and quieter than the outgoing 1.4-liter engine that's used in the current Volt. Fuel economy and EV range specs for the next-gen Volt are not expected until the full car is revealed at the Detroit Auto Show in January.
