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:

Best car infotainment systems: From UConnect to MBUX, these are our favorites

Declaring one infotainment system the best over any other is an inherently subjective matter. You can look at quantitative testing for things like input response time and various screen load times, but ask a room full of people that have tried all car infotainment systems what their favorite is, and you’re likely to get a lot of different responses. For the most part, the various infotainment systems available all share a similar purpose. They aim to help the driver get where they're going with navigation, play their favorite tunes via all sorts of media playback options and allow folks to stay connected with others via phone connectivity. Of course, most go way beyond the basics these days and offer features like streaming services, in-car performance data and much more. Unique features are aplenty when you start diving through menus, but how they go about their most important tasks vary widely. Some of our editors prefer systems that are exclusively touch-based and chock full of boundary-pushing features. Others may prefer a back-to-basics non-touch system that is navigable via a scroll wheel. You can compare it to the phone operating system wars. Just like some prefer Android phones over iPhones, we all have our own opinions for what makes up the best infotainment interface. All that said, our combined experience tells us that a number of infotainment systems are at least better than the rest. WeÂ’ve narrowed it down to five total systems in their own subcategories that stand out to us. Read on below to see our picks, and feel free to make your own arguments in the comments. Best infotainment overall: UConnect 5, various Stellantis products Ram 1500 Uconnect Infotainment System Review If thereÂ’s one infotainment system that all of us agree is excellent, itÂ’s UConnect. It has numerous qualities that make it great, but above all else, UConnect is simple and straightforward to use. Ease of operation is one of the most (if not the single most) vital parts of any infotainment system interface. If youÂ’re expected to be able to tap away on a touchscreen while driving and still pay attention to the road, a complex infotainment system is going to remove your attention from the number one task at hand: driving. UConnect uses a simple interface that puts all of your key functions in a clearly-represented row on the bottom of the screen. Tap any of them, and it instantly pulls up that menu.

2022 Cadillac CT5-V Blackwing First Drive Review | Peak oil

We may have embraced the coming of electrification. We may love a good, high-performance hybrid or EV. We could quite frankly not care less how a car makes power, so long as the end result is satisfactory. But man, nothing suits a big, square-shouldered American sedan quite like a V8. Question our commitment to Mother Gaia if you must, but the blat of a small block is the bass line in the song of American speed. And now onstage for the V8's farewell tour is the 2022 Cadillac CT5-V Blackwing, a midsize, manual-transmission luxury sedan that comes out swinging with a hand-built, supercharged 6.2-liter V8 making 668 horsepower and 659 pound-feet of torque. The CT4-V Blackwing may be great in its own right, but it's still down a pair of cylinders. The old Cadillac CTS-V (S not 5) was never the slimmest, sharpest or most luxurious sport sedan money could buy, but it always offered excellent performance for its price. It was also one of the few midsize manual transmission holdouts, at least until the third-generation V model debuted in 2016; for its brief run, it was offered only with the eight-speed automatic. Its spirit lives on in the CT5-V Blackwing, but Cadillac refined the formula significantly for its transition to the updated Alpha platform. The manual is back, it gained 28 horsepower and 29 pound-feet of torque, and the aerodynamics and braking were completely overhauled for this, the final iteration of the V8-powered Cadillac sport sedan. Apart from the larger footprint and all that comes with it, most of the Blackwing formula carries over almost unchanged to the CT5-V from its smaller CT4-V sibling. A six-speed manual gearbox is standard with a 10-speed auto available as an upgrade (which it truly is, in some ways). The electronically controlled mechanical limited slip differential, fourth-generation Magnetic Ride Control and various other tweaks made their way here too, but there are a few noteworthy deviations. Let’s start where the CT5-V stops: the brakes. Since the larger, heavier CT5 needs more braking capacity, its wheels grew an inch in diameter to accommodate a bigger set of stoppers. The wheels are wider too, the better to fit its Michelin Pilot Sport 4S tires in 275/35ZR19 (front) and 305/30ZR19 (rear) – 20 mm wider up front and 30 mm wider out back than the 18-inch tires on the smaller CT4-V Blackwing. Exclusive to the CT5 is a carbon-ceramic brake package that reduces unsprung mass by 53 pounds and rotating mass by 62 pounds.
