Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

GM recalls half-million full-size SUVs to address seatbelt issue

GM is recalling its redesigned full-size SUV models to address improperly riveted mounts securing the third-row seatbelts that may fail in the event of an accident. The population includes the 2021-2022 Cadillac Escalade and Escalade ESV, 2021-2022 Chevrolet Suburban and Tahoe, and 2021-2022 model year GMC Yukon and Yukon XL, for a total of 484,155 vehicles. "Operators at the supplier’s manufacturing plant may have not properly followed manufacturing processes and inadvertently missed the rivet forming operation," GM said in its defect report to NHTSA. "In certain of these vehicles, the rivet that retains the buckle to the mounting bracket in the left or right side third-row seatbelt buckle assembly may not have been properly formed during the manufacturing process. If the third-row seatbelt assembly is not properly riveted, it may not properly restrain occupants in a crash, increasing the risk of injury." Fortunately, the fix is relatively simple. GM service technicians will inspect the rivets on the rear seatbelt buckle assemblies and replace the entire unit if the rivets are not to spec. Dealer notifications have already been distributed; owners should receive notice start in September. Related video: Cadillac Chevrolet GM GMC Ownership Safety SUV

UAW Chief Shawn Fain disrupts Detroit's labor tradition

He's known to quote the Bible and Nation of Islam civil rights leader Malcolm X. He's a social media fanatic who keeps the pay stubs of his union member grandfather in his wallet. And now, Shawn Fain is representing nearly 150,000 auto workers in one of the biggest labor strikes in decades. In taking action against all three Detroit carmakers, Fain, the head of the United Auto Workers, has remade the strategy of the union he leads, choosing a bolder, much riskier path than his predecessors after he won office by a narrow margin in a first-ever direct election earlier this year. The strike started as the clock hit midnight on Friday, and followed Fain's decision to open negotiations with Ford Motor, General Motors and Stellantis simultaneously and eschew public niceties involving choreographed handshakes that famously kicked off previous negotiating efforts. The strategy is not without risk. A weeks-long strike would hit workers who live paycheck to paycheck, while the Detroit Three automakers have billions in cash to withstand the walkout. Fain, 54, has made creative use of social media, appearances on network and cable news programs and alliances with high-profile progressive politicians such as U.S. Senator Bernie Sanders, to reframe the UAW's contract bargaining as a battle to re-set the balance of power between workers and global corporations. He has rebutted automakers' concerns about labor costs by pointing out that they have poured billions into share buybacks to benefit investors. "If they’ve got money for Wall Street they sure as hell have money for the workers making the product," he said. “We fight for the good of the entire working class and the poor." In lengthy social media talks to UAW members, Fain alternates quoting Bible verses with the use of charts and graphs to dissect wage and benefit offers from the automakers - details his predecessors kept behind closed doors during bargaining crunch time. Fain, in his unorthodox approach, ran what amounted to a public auction among the companies to push each one to top the other to avoid a costly walkout. Prior UAW presidents picked just one automaker to set a pattern for the other two. Over and over, Fain has told UAW members at the Detroit Three that they can reverse 20 years of wage and retiree benefit concessions, stop further plant closures and end a seniority-based, tiered compensation system that pays new hires as much as 44% less than veteran workers.
