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.

GMC Safari GT, a rad-era hauler with custom-van swagger

The GMC Safari van, along with its Chevy Astro sibling, performed yeoman service ferrying passengers and hauling cargo for two decades starting in 1985. But one special variant, the Safari GT — and, at Chevrolet, the Astro RS — added an unexpected dollop of swagger. Those vans had a custom look that was straight out of the '70s "sin bin" era. One of those Safari GTs is up for grabs right now, fittingly, on the RADforsale auction site. The option package at both GMC and Chevrolet was coded BYP, the GT Sport Package, and it appears to have been offered from 1990 to 1994. Its defining element was the two-tone paint treatment shown here, with black on the lower body and the greenhouse, and your choice of white, silver, blue, gold, or red as the main body color. Blanked out rear quarter windows and "simulated air exhaust louvers" behind the middle side windows added a further bit of style (long-wheelbase XT versions skipped that flourish). Also included were a front air dam, blacked-out grille, aluminum rally wheels, and a sport suspension. This 1991 Safari GT appears to have been further sportified with a lower-body aero kit, a rooftop spoiler, and aftermarket wheels. This rear-wheel-drive, standard-wheelbase model is powered by a 4.3-liter V6 hooked to a four-speed automatic transmission. It has traveled a relatively low 126,000 miles and looks to be in exceptionally good shape — particularly given that most of these vans lived a hard life. At this writing, bidding stands at $5,100 with bidding to end May 21. That suggests this Astro GT will bring a strong price — but if you want one, you may be hard-pressed to find another.

2019 GMC Sierra 1500 pickup teased on Twitter

GM's half-ton pickup line will be fully rounded up later this week when the new GMC Sierra 1500 is revealed. Though the unveiling is on March 1, GMC has provided a teaser of the new truck ahead of time on Twitter. It shows only the front fascia, but considering the Sierra's history of simply being a badge-engineered Silverado, it's arguably the most important angle of the truck. The teaser confirms a few things we were expecting based on past spy shots. The headlights look much more conventional than the Silverado's rather small units. The Sierra's grille, unlike the Silverado's, will also rise above the tops of the headlights, providing more of a big-rig appearance. We also finally get to see the GMC badge on the front of the Sierra, and it looks like it's an enormous rendition. As for the rest of the truck, previous spy shots have shown the Sierra will have other subtle styling changes from the Silverado. The wheel wells are shaped differently, and the taillights will be unique to the GMC. The interior of the new Sierra will look almost identical to that of the Silverado, with the exception of a few minor trim details. We also expect the Sierra to use the same engine lineup as the Chevy's, which at this point we know will consist of a 3.0-liter turbocharged diesel inline-six, and naturally aspirated 5.3- and 6.2-liter V8s.
