GM might lose 90-year U.S. sales crown over chip shortage

Automotive News editor Nick Bunkley tweeted on October 1 that according to AutoNews data, General Motors "has been the largest seller of vehicles in the U.S. every year since passing Ford in 1931." With automakers having turned in light car and truck sales data for the first three quarters of 2021, GM's 90-year-run might not reach 91. According to AN figures, Toyota was 80,401 vehicles ahead when the October workday started. Worse, GM is so far behind its historic pace that it might only sell enough light vehicles in the U.S. to match its numbers from 1958.  Meanwhile, the New York Times put a few more salient numbers to the pain GM and Toyota are enduring alongside the the rest of the industry. GM sold 33% fewer cars in Q3 2021 than it did in Q3 2019 during the dark days of the pandemic, 446,997 units this year as opposed to 665,192 last year. GM's Q3 2020 was only down 13% on Q3 2019. Over at Toyota, the bottom line showed a 1% gain in Q3 2021 compared to 2020, with 566,005 units moved off dealer lots. The finer numbers show two steps forward and one step back, though; Toyota's September sales were down 22% compared to last year.  GM remains optimistic about what's ahead, GM's president of North American operations telling the NYT, "We look forward to a more stable operating environment through the fall." We'd like to see that happen, but we don't know how it happens. The chip shortage said to have been the inciting incident for the current woes isn't over, and not only can no one agree when it will be over, the automakers, chip producers, and U.S. government still can't get on the same page about who needs what and when. Looking away from that for a second shows articles about "No End In Sight" for supply chain disruptions in early September, before China had to start working through power supply constraints, global supply chain workers started warning of a "system collapse," and roughly 500,000 containers sat waiting to be unloaded at Southern California ports — a record number seemingly broken every week. And back to chips, we're told just a few days ago the chip shortage is "worse than we thought."   For now, the NYT wrote that GM dealer inventory is down 40% from June to roughly 129,000 vehicles, and down 84% from the days when dealers would cumulatively keep about 800,000 light vehicles in stock. However, GM just announced it would have almost all of its U.S. facilities back online next week, although some would run at partial capacity.

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.

Where the 2023 GMC Sierra AT4X fits into the hierarchy of off-road trucks

The world of off-road pickups sure seems like it's getting crowded, but the reality is that half-ton trucks were always pretty capable, even with what seemed like fairly basic 4x4 packages. It wasn't until recently that manufacturers really started to carve out different off-road niches for their mainstream pickup offerings. With the introduction of the 2022 GMC Sierra 1500 AT4X (alongside its mechanical twin, the Chevy Silverado ZR2), the crowd has grown even thicker. Even we have trouble keeping up with the increased segmentation of off-road pickup trucks, so we threw together this handy guide to help you understand just where these various packages fit into the broader pickup hierarchy. Let's dive in.  Your basics If we say "Z71" or "FX4" to you, both will probably ring a bell. That's because they've been around a few days short of forever and their respective customers have grown so used to these package codes that OEMs got into the habit of just plastering them on the side of so-equipped truck beds. Anybody who sells a pickup truck offers some sort of basic off-road prep package like this one. Z71 is found on GM vehicles; FX4 is Ford's. Ram just calls it "Off Road Group," but no matter what you call them, they're all pretty similar.  Typical upgrades for this category include some additional ground clearance, a basic all-terrain tire, heavy-duty suspension upgrades and likely either a limited-slip or locking rear differential. These are pretty handy for anything beyond a rutted dirt road. On newer trucks — especially on higher trim levels — you'll probably also get some dedicated off-road drive modes.  Mid-range This is where things start to get interesting. To qualify for this category, a locking rear differential is a must. Most of the names in this segment are well-established too, though some (Nissan Titan Pro-4X, anyone?) may not necessarily be on your radar. The Toyota Tundra TRD Pro checks in here, as does the Ram Rebel, Chevy Silverado Trail Boss and GMC Sierra AT4 (no X!).  Realistically, if there's somewhere you need to go and one of these trucks won't do it, you might want to consider a helicopter. But it's 2021, and our thirst for capability is strong, so of course, there's a way to spend more of your money on this type of thing. Onward! Entry-hardcore Here we are, the home of the new 2022 GMC Sierra AT4X and Chevrolet Silverado ZR2. This is a tiny niche, otherwise occupied only by the Ford F-150 Tremor.
