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:

Cadillac ELR update delayed over autonomous drive systems issues

Rumors had been circulating that the 2016 Cadillac ELR would bow in Los Angeles recently, featuring, in Cadillac's own words, "engineering enhancements." The rumors and that quote are as far as it got – the updated ELR pulled a no-show in LA, and no one outside of the brand appears to know when it will appear. GM Inside News says its sources at Cadillac pinned the ELR's absence on some autonomous driving features not being ready to reveal. According to GMI, Cadillac insiders say the upgraded ELR will be a "highly autonomous vehicle," and the company needs more time to gets its systems polished. The site says "it's not unreasonable to assume that ELR will be [the] vehicle" that gets Cadillac's Super Cruise technology, but that seems a lot more involved than "engineering enhancements," and in September Cadillac said we'd see it sometime in the next two years. It's possible the wait for the 2016 ELR and its secrets might only be a couple of months: the next-generation Chevrolet Volt, which shares a platform with the ELR and whose engineering updates we know quite a bit about, is scheduled to appear at the 2015 Detroit Auto Show in January.

Cadillac's striking Escala concept is reportedly headed for production

Cadillac is reportedly planning a new flagship four-door, and it won't be based on its alphanumeric naming system a la the CT6. It'll be the Escala, the stunning concept fastback it revealed in 2016 in Pebble Beach. The news comes via Autoline, which cites AutoForecast Solutions. The Escala is said to be planned for production starting in December 2021 at GM's Detroit-Hamtramck plant, which currently builds the CT6, Buick LaCrosse and Chevrolet Volt and Impala. That suggests the Escala, which was branded as a four-door coupe, will likely keep that layout. It'll also be built on the CT6 platform. Cadillac has been talking about fitting a flagship sedan above the CT6 for years, and the Escala's design language has been influencing bits of other Cadillac models, from the refresh of the CT6 to the broad grille shape on the new XT4 crossover, which debuts at the New York Auto Show next week. The concept Escala featured a wide, muscular stance and a minimalist, white mid-century modern interior aesthetic, with tail lamps that evoke waterfowl in flight. Interestingly, it came equipped with a 4.2-liter twin-turbo V8 with cylinder deactivation, which Cadillac President Johan De Nysschen said at the time was "absolutely worthy of a car of this caliber." But with such a long horizon before production, there's obviously lots of time to develop a more pragmatic production model and cue ravenous speculation. Or, for that matter, to decide to rename it something like the CT8.
