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:

Coronavirus shakes up America's truck market: GM outselling Ford and Ram

FCA, Ford and General Motors joined the rest of the U.S. auto industry in taking heavy volume hits due to coronavirus-related shortages of both cars and customers. The saying goes that a rising tide lifts all boats; it stands to reason, then, that a falling one would have the opposite effect.  However, as we learned Thursday, the automotive market can behave in unpredictable ways. While the F-Series remained the best-selling nameplate in Q1, GM's full-size trucks are now outselling Ford's again for the first time in years, and with this upward thrust from the General, FCA's Ram was unceremoniously booted out of a hard-earned second place.  While late-March sales declines hit just about every major automaker in one way or another, the model-by-model results weren't nearly so uniform. And because the market tends to be a zero-sum game, for every winner, there generally has to be a loser.  In this case, that winner was GM, and its rise had to come at the expense of another automaker, in this case, Ford. F-Series sales dropped 13.1 percent in the first quarter of 2020, while sales of GM's full-sized Silverado and Sierra surged nearly 28% in the same period. FCA's Ram lineup managed a steady-as-she-goes 7% increase. All-in, GM finished the quarter with 197,743 full-size trucks sold to Ford's 186,562. Here's the full breakdown: Ford F-Series: 186,562  Chevrolet Silverado*: 144,734 Ram P/U: 128,805 GMC Sierra: 53,009 *includes 1,036 Medium Duty sales Things are a but murkier in the midsize segment, where the Chevy Colorado slipped 36% to just 21,430 units sold — just a few hundred better than the slow-selling Ford Ranger's Q1 numbers. The GMC Canyon experienced an almost identical slide, finishing the quarter with just 4,483 units sold. For perspective, Jeep sold more than 15,000 Gladiators and Toyota's midsize Tacoma slipped less than 8%, finishing the quarter with nearly 54,000 sales.  We suspect this discrepancy in full- and mid-size truck sales comes from shifting incentives. Ford, GM and FCA would like to keep selling bigger trucks because there's far more profit margin built into their list prices. Even with tens of thousands of dollars in manufacturer money on the hood, big trucks still make money.  Since these automakers report quarterly, we won't get another good look at these numbers until July, but if you thought that 2019 represented the new normal for U.S. auto sales, well, think again.

GM 8-speed transmission lawsuit granted class action certification

A story on Autoblog about potentially faulty 8-speed automatic transmissions from General Motors in 2019 has, as of the day this was published, 166 comments, mostly from owners of cars and trucks who say they are experiencing "a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." At the time, lawyers were seeking statewide classes in at least six states. As of today, the Detroit Free Press reports that a judge has granted class action status to a lawsuit brought by 39 plaintiffs across 26 states covering the transmission issue. The lawsuit specifically applies to vehicles that are equipped with GM's 8L90 or 8L45 8-speed automatic transmissions made between 2015 and March 1, 2019. Both of these transmissions are similar units, the 8L45 being slightly lighter version used in fewer vehicles than the beefier 8L90, and are designed for front-engine, rear- or all-wheel drive applications. The lawsuit alleges that the erratic transmission behavior makes some vehicles unsafe to drive. Ted Leopold, partner at Cohen Milstein and the court-appointed lead counsel for the case, said in a statement, "General Motors knowingly sold over 800,000 eight-speed transmission vehicles, which they knew to be defective for years, and yet made the business decision not to tell its customers before purchase." He added, "Dealers were directed to tell the customers that harsh shifts were ‘normal' or ‘characteristic.Â’ Such decision making is both highly irresponsible and emblematic of what GM believes it can get away with." The vehicles included in the court order with potentially faulty transmissions includes: 2015-2019 Chevrolet Silverado 2017-2019 Chevrolet Colorado 2015-2019 Chevrolet Corvette 2016-2019 Chevrolet Camaro 2015-2019 Cadillac Escalade and Escalade ESV 2016-2019 Cadillac ATS, ATS-V, CTS, CT6, and CTS-V 2015-2019 GMC Sierra, Yukon, Yukon XL, and Yukon Denali XL 2017-2019 GMC Canyon Some additional details of the lawsuit can be found at the Cohen Milstein site, including claims that "since 2015, GM has issued thirteen versions of a “technical service bulletin,” or “TSB,” related to this shifting issue alone." The statement from Cohen Milstein says that a "second action regarding GM vehicles with 8L transmissions is also underway in Battle v. General Motors, LLC, 2:22-cv-108783.
