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:

GMC Canyon, Chevy Colorado diesels finally heading to dealers

Customers who have been waiting to receive their diesel-powered Chevrolet Colorados and GMC Canyons should be relived to hear that GM will finally start to ship them out of the Wentzville Assembly Plant. "The highly anticipated 2016 GMC Canyon diesel has begun shipping to dealers," a company spokesperson confirmed to The Detroit News. The trucks originally had a fall launch date, but a final review forced a delay in deliveries. The 2.8-liter four-cylinder diesel in the midsize trucks produces 181 horsepower and 369 pound-feet of torque, and the company touts the engine's low emissions. The Environmental Protection Agency and California Air Resources Board even put the mill through extra scrutiny with a real world test in the wake of VW's diesel scandal, and the Duramax passed with no problems. At that time, a Chevy spokesperson told Autoblog that the models' launch was on track. The Duramax engine adds $3,730 to the price of a comparable V6 model, but they're the most fuel-efficient pickups on the market. The EPA estimates the twins at 31 miles per gallon highway, 22 mpg city, and 25 mpg combined in two-wheel drive form and 29/20/23 with four-wheel drive. Buyers likely can't wait to finally experience these pickups after reading a heap of positive reviews. The Colorado diesel recently earned Motor Trend's Truck of the Year award. We also came away impressed with it during our First Drive and liked the Canyon during our Quick Spin. Related Video:

Three automotive tech trends to watch in 2018 and beyond

Every year, technology plays a bigger and bigger role in the auto industry. To put things in perspective, 10 years ago iPod integration and Bluetooth were cutting-edge in-car innovations, and smartphones and apps weren't yet a thing since the first iPhone was only about six months old. And I can't recall anyone talking about autonomous cars. Compare that to today, with mainstream coverage of the auto industry dominated by autonomous technology, along with electrification and almost every move made by Tesla. These three topics were the most significant trends of car tech in 2017 and I believe they will continue to shape the auto industry in 2018 and beyond. Let's examine them. Full Autonomy Gets Closer to Reality While there were many developments this year that indicate we're inching closer to fully autonomous vehicles, I was behind the wheel for hours to witness one of them. In October I had the chance to test Cadillac Super Cruise on a 700-mile, 11-hour drive from Dallas to Santa Fe – and had my hands on the wheel for maybe 45 minutes max throughout the entire trip. Super Cruise is far from making the Cadillac CT6 or any GM vehicle fully autonomous, and has limitations such as functioning only on pre-mapped main highways. While it simply adds a layer of lane centering to adaptive cruise control, the technology will go a long way in making mainstream drivers more comfortable with letting machines take over. On a separate front, GM is pushing ahead with fully autonomous vehicles and announced last month that it plans to launch of fleets of self-driving robo-taxis in several urban areas in 2019. While most automakers are also in the race to make autonomous cars a reality, GM's turbocharging of its efforts appeared to be in response to Waymo, which announced just weeks earlier that its Early Rider Program in the Phoenix area would go completely driverless. The Early Rider Program launched last April, offering the public a chance to ride in Waymo's autonomous Chrysler Pacifica minivans. In this new phase of testing, Waymo is using its own employees as guinea pigs instead of the public while the vehicles operate without a human behind the wheel, and takes another giant step forward for fully autonomous driving.
