GM recalls 638,000 U.S. SUVs, trucks for unintended braking

WASHINGTON — General Motors is recalling 638,000 U.S. sport utility vehicles and pickup trucks because a wheel-speed sensor could fail and cause unintended braking, it said Thursday. The recall covers 2015-2020 Chevrolet Suburban, Tahoe, and Yukon and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. The sensor failure could result in unintended activation of the driveline protection system, and cause unintended braking of the wheel on the opposite side of the failed sensor. That could cause the vehicle to pull to one side unexpectedly, increasing the risk of a crash, the Detroit automaker said. GM said it was not aware of any crashes relating to the issue but found 150 field claims alleging the condition caused unintended braking or lateral vehicle motion. A GM dealer in May submitted a warranty report relating to the issue in a 2018 GMC Yukon, and two days later, a GM brand quality manager submitted the report to GMÂ’s Speak Up For Safety program that tracks potential safety issues, which prompted a GM investigation and testing.

Farley reacts as UAW expands strike against Ford, GM

Members of the United Auto Worker union walk out of the Chicago Ford Assembly Plant as Lance Williams from Lansing, Ill., waves the UAW flag Friday. (AP)   As the United Auto Workers walk off the job at an additional Ford and General Motors plant, Ford CEO Jim Farley addressed investors and members of the media Friday, pleading the case for the company's latest overture to the union and addressing both public and investor concerns regarding the core issues facing American manufacturing.  Farley made a public case for Ford's efforts to resolve the dispute, expressing frustration with the ongoing stalemate and noting both the concessions Ford offered before the strike began and the signing of a contract with Canada's Unifor. Farley also acknowledged UAW President Shawn Fain's success in getting the union's message out, quipping: "Shawn has been on TV more than Jake from State Farm at this point." The first-ever simultaneous strike against the Detroit Three automakers enters its third week with threats of continued expansion, but little in the way of obvious concrete progress.  "If the UAW’s goal is a record contract, they have already achieved this," Farley said. "It is grossly irresponsible to escalate these strikes and hurt thousands of families." Farley also lamented the fact that EVs have become the subject of partisan conflict, with the company's recently announced battery production facilities taking heat from both pundits and investors as Ford was forced to press pause on the venture while negotiations continue. Former President Donald Trump dropped in to Michigan this week to declare EVs the enemy of blue-collar jobs. "They've become a political football, and that's a shame," he said. Friday saw an expansion of the UAW strike to Ford's Chicago assembly plant and GM's Lansing, Delta Township, Michigan, assembly plant, covering about 7,000 workers, Fain said in an announcement, bringing the total number of workers on the picket lines to 25,000. The strike will not include any additional members at Stellantis, where talks have reportedly been more productive. The Ford and GM plants went on strike at noon Eastern today (Friday). Ford builds the Explorer and Lincoln Aviator in Chicago. GM's Delta Township plant builds Chevy Traverse and Buick Enclave. "Despite our willingness to bargain, Ford and GM have refused to make meaningful progress," Fain said in a video address Friday morning.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.
