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:

2020 Cadillac XT4 Review and Buying Guide | Competence and curb appeal

The 2020 Cadillac XT4 is a handsome little crossover distinctively sized between two segments. This allows it to boast backseat space on par with larger SUVs like the Audi Q5, while being a bit more park-able and fuel efficient like the BMW X1. There should definitely be a Goldilocks "just right" thing going on for many shoppers. Cadillac's baby SUV also impresses on the technology front, boasting loads of standard, advanced features along with a user-friendly touchscreen interface that shouldn't be too hard to figure out. There are dynamic missteps, though. The steering, throttle and brake pedals lack the driver-oriented response and feedback we've come to expect from Cadillac's sharply tuned sport sedans, while also not exactly possessing the nice-and-easy isolation of Caddy's past. In either scenario, we're not sure it "drives like a Cadillac" despite some otherwise impressive engineering going on underneath that handsome skin. The XT4 is also pretty expensive given its features, size and interior quality. Competitors both larger (Acura RDX) and smaller (Volvo XC40) provide better value. Still, as we noted in our XT4 first drive, there's enough novel tech to provide bragging rights, it's obviously a Cadillac in design (and definitely not just a rebadged Chevrolet in execution), and it's a pleasing enough place to sit while scooting around in traffic. It has competence and curb appeal, which count for a lot. What's new for 2020? After being an all-new model last year, the XT4 heads into 2020 with some noteworthy features updates: Forward collision warning and automatic emergency braking are now standard, while the Premium Luxury trim level gets the hands-free power liftgate as standard equipment.   What's the XT4's interior and in-car technology like? The XT4's interior design isn't as memorable as that of its exterior, nor its stylish Volvo XC40 and Lincoln Corsair competitors. It's a bit generic, which just doesn't seem right for a Cadillac. Materials quality is acceptable when closer to its base price, but begins feeling less so as options are added and the price tag rises. We've also driven multiple XT4's with an annoying rattle in the B pillar. Standard infotainment technology is abundant. Apple CarPlay and Android Auto are included with the standard 8-inch touchscreen and benefit from a pair of USB ports: one standard USB-A and the other a newer USB-C.

Despite strong profits, GM still fighting flat market share

Looking at the progress General Motors has made since it entered bankruptcy, it's easy to forget that the company still has a long way to go before it's the juggernaut it once was. A recent report from Reuters points out that, while GM is making money, it isn't making any gains in terms of US market share. Quite the opposite, really. Consider this factoid: In 1963, nearly half of the cars sold in the United States were from Chevrolet, Cadillac, Buick, GMC or Pontiac. Now, the company's US market share is stagnant at 17.9 percent. That same number is half of just Chevy's 1963 market share. This is all despite GM going on a binge replacing or updating its models. "Market share increases are not instantaneous," Mark Reuss told Reuters at the 2014 Detroit Auto Show. "We've got a lot of baggage. Don't underestimate what people though of us, or these brands, through these hardships and 30 years." The reasons for the stagnant market share are numerous. Reuters points out that retooling of factories and a focus on limiting incentives are both good things for profit, but not necessarily for market share. There's also the troubling turnover of the brand's marketing department. These issues don't change the fact that Chevrolet has lost 1.4 percent of its market share in two years, and that Cadillac - arguably GM's most improved brand overall - has lost 1.2 percent in the same period. Part of that can be blamed on GM's avoidance of fleet sales in favor of more profitable customer sales. "Our focus has really been on retail and that's where we've got the growth," said Alan Batey, GM's interim global marketing boss. "We want to grow GM and that means growing market share and profits, but it's not at all costs," Reuss said.
