2024 GMC Acadia gets bigger, goes entirely turbocharged

For an entire generation now, the GMC Acadia, the brand's largest unibody SUV, has sat in an unusual zone in between the typical midsize two-row and large three-row segments. But the completely redesigned 2024 Acadia is stepping confidently into the latter camp, growing to roughly match its cousin, the also fully redesigned 2024 Chevy Traverse. And adding to its greater size and performance, the Acadia brings unique exterior and interior design. The size increase is impressive. The wheelbase has grown 10.6 inches, overall length by 8.4, and overall height by 3.2. GMC claims this has increased cargo space by 80% and second-row seat room by 27%. These changes all make it about the same size as the Chevy, too, instead of a smaller option.  This content is hosted by a third party. To view it, please update your privacy preferences.

The flanks really depart from the aggressive shape of the Traverse. It also skips the fat C-pillar. GMC designers noted they specifically worked to reduce the size of that pillar, in part to improve visibility for third-row passengers. Conversely, the D-pillar is relatively large and is finished in body color to reveal it. But to keep it from looking overly large, there's a black plastic panel that helps give the rear window a bit of a wraparound effect. The taillights also have a gloss black panel to blend them into the rear window area and reduce the visual mass of the hatchback. The interior is the biggest differentiator between the Traverse and Acadia, though. The entire dashboard is unique to the Acadia. The 11-inch instrument display sits under a cowl that extends horizontally to meet the unique vertical 15-inch infotainment screen. That screen overlaps a squared-off, horizontal dash design, and it's flanked by vertical air vents. The Acadia picks up a column-mounted shifter, too, freeing up space for storage in the center console. There are practically no parts directly pulled from other GM products. And unlike GM's upcoming EVs, the Acadia will have Apple CarPlay and Android Auto functionality. Individual Acadia models even have unique features. The luxury Denali trim and off-road focused AT4 trim both return. The AT4 stands out the most with an extra inch of ground clearance in part from the all-terrain tires on 18-inch wheels.

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.

NHTSA closes 4-year GM investigation, issues common sense advisory [w/video]

Since January 2011, the National Highway Traffic Safety Administration has been investigating a possible problem with corroding brake lines in General Motors' GMT800-platform models, like the Chevrolet Silverado and Suburban and GMC Sierra, in states with salt on their roads in the winter. However, as opposed to launching a full recall of millions of vehicles, the government is issuing a common-sense safety advisory to all drivers in snowy states to keep their vehicle's undercarriage clean. It even has a video explaining things. "Older-model vehicles, often driven in harsh conditions, are subject to corrosion over long periods of time, and we need owners to be vigilant about ensuring they, their passengers, and others on the roads are safe," said NHTSA Administrator Mark Rosekind in the announcement of the end of the investigation. The agency was clear in its report that "brake line corrosion seen in the GM vehicles was not unique," and the government "has not identified a defect that would initiate a recall order." Instead NHTSA is advising drivers, especially those of vehicles from before 2007, to wash their vehicle's undercarriage in the winter and spring to remove salt or other de-icing chemicals. It also recommends regular checks by a mechanic to make sure everything is in proper order. According to the investigation documents, for just the GMT800 platform models, NHTSA found 3,645 complaints of brake line corrosion, which included allegations of 107 crashes and 40 injuries. The issue was found to be more common in vehicles over 10 years old. GM has released a statement (embedded below) that the company "supports the consumer advisory from NHTSA urging regular maintenance and care of brake lines on older vehicles." NHTSA Closes Investigation into Brake-Line Failures NHTSA 13-15 Thursday, April 9, 2015 Agency issues safety advisory on preventing undercarriage corrosion WASHINGTON – The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today issued a Safety Advisory and consumer video encouraging owners of model year 2007 and older trucks, SUVs and passenger cars to inspect brake lines and thoroughly wash the underside of their vehicles to remove corrosive salt after the long winter in order to prevent brake-line failures that increase the risk of a crash.
