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 faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.

GM earnings rise 1% as buyers pay more for popular pickups

DETROIT — General Motors said Thursday that higher prices for popular pickup trucks and SUVs helped overcome slowing global sales and profit rose by 1% in the second quarter. The Detroit automaker said it made $2.42 billion, or $1.66 per share, from April through June. Adjusting for restructuring costs, GM made $1.64 per share, blowing by analyst estimates of $1.44. Quarterly revenue fell 2% to $36.06 billion, but still beat estimates. Analysts polled by FactSet expected $35.97 billion. Global sales fell 6% to 1.94 million vehicles led by declines in North America and Asia Pacific, Middle East and Africa. The company says sales in China were weak, and it expects that to continue through the year. In the United States, customers paid an average of $41,461 for a GM vehicle during the quarter, an increase of 2.2%, as buyers went for loaded-out pickups and SUVs, according to the Edmunds.com auto pricing site. The U.S. is GM's most profitable market. Chief Financial Officer Dhivya Suryadevara said she expects the strong pricing to continue, especially as GM rolls out a diesel pickup and new heavy-duty trucks in the second half of the year. "We think the fundamentals do remain strong, especially in the truck market," she said, adding that strength in the overall economy and aging trucks now on the road should help keep the trend going. Light trucks accounted for 83.1% of GM's sales in the quarter, and pickup truck sales rose 8.5% as GM transitioned to new models of the Chevrolet Silverado and GMC Sierra, according to Edmunds, which provides content to The Associated Press. As usual, GM made most of its money in North America, reporting $3 billion in pretax earnings. International operations including China broke even, while the company spent $300 million on its GM Cruise automated vehicle unit. Its financial arm made $500 million in pretax income. Suryadevara said GM saw $700 million in savings during the quarter from restructuring actions announced late last year that included cutting about 8,000 white-collar workers through layoffs, buyouts and early retirements. The company also announced plans to close five North American factories, shedding another 6,000 jobs. About 3,000 factory workers in the U.S. whose jobs were eliminated at four plants will be placed at other factories, but they could have to relocate. GM expects the restructuring to generate $2 billion to $2.5 billion in annual cost savings by the end of this year.
