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:

Hotter Cadillac CT4-V prototype spied testing at GM's Proving Grounds

Cadillac already teased us once with the hotter CT4-V and CT5-V at the Belle Isle Grand Prix, but these photos are still the best look yet at what's next for the Cadillac V-Series. The car we're looking at in heavy camouflage here is a high-performance CT4, but we don't really have a name to call it at this point. Cadillac hasn't said, so it could be anything. We'll just refer to it as the faster V, as it's certainly looking a bit more racy than the warmed-over CT4-V already revealed. While the styling isn't drastically different from the CT4-V already out there, the front intake and openings look deeper and more aggressive. The middle, raised section of the hood is a little taller and the whole front-end design looks a lot like the one teased in Belle Isle. This vehicle even appears to have the same mirror design as the faster V. The side sills, quad exhaust tips and wide rear tires lend this prototype an aggressive look, but we did note that it doesn't have the big ducktail spoiler we saw teased previously. Maybe Cadillac is trying to keep a low profile while testing. A keen eye will notice a wild apparatus attached to the front, which would serve as a great jousting pole if you were into that kind of thing. We don't know exactly when Cadillac plans to introduce the faster V machines, but we wouldn't doubt if it happened before the year was out. The ATS-V and CTS-V didn't look wholly different than the pedestrian versions of those cars, and this prototype indicates Caddy may follow a similar pattern this time around. All will be explained from GM soon, but for now, we wait.

Cadillac CT4 and CT5 get meaningful updates for 2021

It's common for vehicles to get an update here or there in between full redesigns every five or six years, but the changes being made for the 2021 Cadillac CT4 and CT5, each just introduced last year, represent more than just a little nip and tuck. For starters, Cadillac's excellent Super Cruise will show up on the options sheets for the two sedans early next year in Enhanced form with with Lane Change on Demand functionality. Super Cruise will be offered on Premium Luxury and V-Series trims only. As we already knew thanks to early order guides, a new 12-inch digital instrument cluster that features driver-selectable themes is also on the menu for 2021. A traditional Tour theme is probably what most drivers will default to, while a Sport theme will likely include red accents and performance-monitoring readouts and a Stealth theme will offer minimal information and what we'd guess are non-distracting colors. CT4-V and CT5-V models will get an exclusive Track theme. New for the CT5 Sport trim level is a V Performance package that adds upgraded suspension bits, Magnetic Ride Control and a mechanical limited-slip differential. V Performance front brake calipers from Brembo are also optional on Sport models. Additionally, a new Diamond Sky special edition package will be offered on Premium Luxury CT4 and CT5 models, adding interior and exterior styling upgrades along with all-season run-flat tires on unique wheels. The package also gets the aforementioned V Performance brakes. Additional updates include wireless Apple CarPlay and Android Auto, SiriusXM with 360L with more than 200 live SiriusXM channels and on-demand programming choices, and a console-mounted rotary infotainment knob that enables left and right clicks to more easily navigate the CUE infotainment system. Buckle to Drive will come enabled from the factory (it can be disabled after purchase) and won't allow the driver to shift into drive unless the seatbelt is buckled. A Teen Driver mode will encourage safe driving from — you guessed it — teens. Forward collision alert, front pedestrian braking, automatic emergency braking and the patented haptic Safety Alert Seat are now standard equipment across the board for both sedans. Check out the image gallery above to see many of the updates, including Super Cruise, the digital instrument cluster and the Diamond Sky edition. Related Video:
