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.

Diesel-powered 2020 Chevrolet Silverado, GMC Sierra get big price cuts

General Motors is reducing the price difference between its diesel-powered light-duty pickups and their gasoline-burning counterparts, according to a recent report. As of September 3, 2020, the Chevrolet Silverado 1500 and the GMC Sierra 1500 benefit from a $1,500 price cut when they're ordered with a turbodiesel under the hood. Enthusiast website GM Authority first reported the news after looking at internal documents sent to dealers across the nation. It wrote the discount applies to in-stock and in-transit units of the Silverado and the Sierra (pictured), and it added dealers will begin receiving amended window stickers on September 8. And, it's not just a quick, easy way for General Motors stores to clear out 2020 inventory. Incoming 2021 models will benefit from it, too. Chevrolet's cheapest diesel-slurping 2020 Silverado, a double-cab LT with two-wheel drive, now starts at $44,000 once a mandatory $1,595 destination charge enters the equation. For context, the same configuration costs $38,795 including destination when it's ordered with the 2.7-liter turbocharged four-cylinder, which is the smallest and cheapest engine on the roster. Selecting the more efficient engine option costs buyers $5,205. At the other end of the spectrum, the crew-cab High Country with a standard cargo box and four-wheel drive is now priced at $59,690. Walk a block to the GMC store, and you'll need to spend between $44,470 (double-cab SLE with two-wheel drive) and $61,685 (crew-cab Denali with a regular cargo box and four-wheel drive) for a diesel-powered Sierra. It doesn't sound like either company is making major mechanical changes to the trucks for 2021. Both are powered by a 3.0-liter straight-six Duramax engine, which makes 277 horsepower and 460 pound-feet of torque. Rear-wheel drive and a 10-speed automatic transmission come standard, and four-wheel drive is offered at an extra cost. In its most efficient configuration, the Silverado returns 23 mpg in the city, 33 mpg on the highway, and 27 mpg in a mixed cycle, impressive numbers for a body-on-frmae pickup that's as heavy as it is capable. Ram's diesel-powered 1500 posts EPA estimates of 22, 32, and 26, respectively. Ford pledged the recently-unveiled 14th-generation F-150 will offer a turbodiesel engine, too, but its fuel economy figures are not available yet.

2023 GMC Sierra prices up, start at $38,995 for Sierra Pro Regular Cab

It was only 90 days ago that GM Authority, typically a reliable source in these matters, reported on pricing for the 2023 GMC Sierra lineup before official numbers were released. Those early figures were apparently just placeholders. Now that GMC's uploaded the full 2023 configurator for the 2023 Sierra, not only are MSRPs higher except on the base trim, the destination charge has risen from $1,795 to $1,895. The sticker prices including destination and their changes from those late August sums are: Sierra Pro Regular Cab Standard Box 2WD Turbo 2.7L I4 L3B $38,995 ($1,025 less) SLE Double Cab Std Box 2WD Turbo 2.7L I4 L3B $52,095 ($1,100) Elevation Double Cab 2WD Turbo 2.7L I4 L3B $53,795 ($1,200) SLT Crew Cab Short Box 2WD 5.3L V8 L84 $57,795 ($1,300) AT4 Crew Cab Short Box 4WD Turbo-diesel 3.0L I6 LZ0 $68,595 ($1,495) AT4X Crew Cab Short Box 4WD 6.2L V8 L87 $83,595 ($3,395) Denali Crew Cab Short Box 2WD 5.3L V8 L84 $67,595 ($1,095) Denali Ultimate Crew Cab Short Box 4WD Turbo-diesel 3.0L I6 LZ0 $82,940 ($745) The Sierra's price bumps ranging from $745 to $3,395 come in tandem with the prices of the 2023 Chevrolet Silverado going up anywhere from $800 to $1,800. The $3,395 MSRP boost on the Sierra AT4X skews the price curve because of extra equipment. GMA reported in July that the standard AT4X would inherit parts from the Sierra ATVX AEV created in collaboration with American Expedition Vehicles. That's what's happened. A revised grille with gloss black and dark nickel trim, AEV front and rear bumpers with increased approach and departure angles, a hot-stamped hardened steel front skid plate inflate the cost and give the ATX4 a little more capability off-road. The equipment list also narrows the gap from the regular AT4X to the AT4X AEV, the latter going just a bit further with four more skid plates, AEV's Salta wheels, and a smattering of black trim around the body. We're still waiting for official pricing on the AT4X AEV. The image above shows shows how similar both trucks will look when the AEV arrives, with the standard AT4X on the left, the AT4X AEV on the right.
