Hagens Berman: Law Firm Behind Many of the Largest Auto Class Actions Sues GM for Engine Failure Defect in Over 800,000 SUVs and Pickup Trucks
DETROIT--(BUSINESS WIRE)--A class-action lawsuit aimed at General Motors accuses the automaker of bungling one of the largest engine recalls in its history, according to Hagens Berman, and abandoning consumers who own or lease one of more than 877,000 vehicles affected by a defect that causes sudden, catastrophic engine failure.
'GM markets itself as an automaker that advocates for the safety of its customers and their families,' Berman added. 'Now would be a great time for GM to fulfill that promise.'
According to the lawsuit filed May 19, 2025, in the U.S. District Court for the Eastern District of Michigan, the defect occurs with no warning in vehicles equipped with L87 6.2L V8 engines with as little as a thousand miles of use, occurring more often at high speeds. According to the class action, GM has known about the defect for several years but failed to disclose it to affected owners prior to the purchase of their vehicles.
If you own a GM-branded vehicle equipped with L87 6.2L V8 engines contact Hagens Berman to find out more about this issue and your consumer rights against GM. Affected model years include 2019-2024 Chevrolet Silverado 1500, 2019-2024 GMC Sierra 1500, 2021-2024 Chevrolet Tahoe, 2021-2024 Chevrolet Suburban, 2021-2024 GMC Yukon, 2021-2024 GMC Yukon XL, 2021-2024 Cadillac Escalade and 2021-2024 Cadillac Escalade ESV.
'What started as a recall has ballooned into what appears to be the need for full engine replacement for at least 870,000 vehicles,' said Steve Berman, managing partner of Hagens Berman and attorney representing affected owners. 'This defect is serious because it involves sudden catastrophic engine failure with no warning and is more common at high speeds. This spells danger for anyone in or near the car.'
'GM markets itself as an automaker that advocates for the safety of its customers and their families,' Berman added. 'Now would be a great time for GM to fulfill that promise.'
According to the lawsuit, GM's L87 6.2L V8 engine connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and catastrophic engine failure. The National Highway Traffic Safety Administration (NHTSA) states in its summary of the defect, '…complainants report a bearing failure that may result in either engine seizure or breaching of the engine block by the connecting rod.'
GM dealerships have reportedly informed consumers that there is no guidance for them to fix the defect at the root of the recall, the lawsuit states.
The lawsuit seeks compensation for those who purchased the affected vehicles under California and Washington state consumer protection laws including false advertising law, unfair competition law and the California Consumer Legal Remedies Act, as well as the Song-Beverly Consumer Warranty Act.
Attorneys say the affected vehicles have significantly suffered in value: 'In addition to rendering the Class Vehicles unsafe to drive, the Bearing Defect significantly reduces the value of the Class Vehicles. And, if GM had disclosed the truth about the Bearing Defect, Plaintiffs would not have purchased their vehicles or would have paid less.'

Tested at Fort Bragg, new military troop vehicle in production in North Carolina
RALEIGH, N.C. (WNCN) — An evolved version of the iconic U.S. military's Jeep was tested in North Carolina at Fort Bragg and is now in production in North Carolina near Charlotte. The 82nd Airborne Division at Fort Bragg helped test and provide feedback as the vehicle was developed. The item has a name that's much longer than 'Jeep' — the Infantry Squad Vehicle, which has now been in the field for a couple of years. It's designed to quickly move up to nine soldiers and their gear over rough terrain — but not as a fighting vehicle because it has no armor, like a Jeep. The U.S. Army says the ISV, officially the M1301, is transported easily by helicopters or other aircraft during air assault and airborne assault missions. The first unit equipped with the ISV was the 1st Brigade Combat Team, 82nd Airborne Division at Fort Bragg. The ISV is made from the road-legal Chevrolet Colorado ZR2 midsize truck but has a doorless design, steel and aluminum body panels, and a rollover bar. Initially, the U.S. Army awarded $214 million for just under 650 vehicles to GM Defense/Ricardo Defense in June 2020. One key aspect of the vehicle is that 90 percent of the parts are commercial off-the-shelf items, which experts say cuts down on costs, stocking spare parts and time needed to fabricate parts. The overall Amy requirement is for 2,593 ISVs, which are built in Mooresville by Hendrick Motorsports and then delivered to the military from a GM center about 20 miles away in Cabarrus County. The GM center, located in Concord, is a 75,000-square-foot facility that was built just for ISV production. Of the total contract, 649 are planned for delivery by this year to 11 infantry brigade combat teams. So far, foreign governments have shown an interest in the ISV, with Canada planning to buy 90 and possibly another 240, according to GM. While the ISV is not armored, troops said its 5,000-pound light weight, low profile and speed are assets. 'When expecting an ambush, we used speed to blow through and return fire,' Pfc. Caden Wilhelm told military officials about testing at Fort Bragg. The 82nd and 101st Airborne Divisions used the ISV to help Hurricane Helene victims in western North Carolina last year.

This Engine Powered More Cars Than Any Other
GM's 3800 still has a huge following to this day, as it was a workhorse for the brand. For more than 30 years, starting in 1975, this reliable V6 powerplant was shoehorned under the hood of more than 25 million vehicles. That includes products ranging from boring sedans up to a turbocharged 20th Anniversary Pontiac Trans Am. While that's impressive, another GM engine handily beats the 3.8-liter V6 as the most produced engine of all time. Yep, it's the small-block Chevrolet. Chevy originally released the small-block in a 265 cubic inch displacement called "Turbo Fire" to power 1955 model year Corvettes and Bel Airs. Although its 180 horsepower output in top tune is lackluster by modern standards, it was a full 30 horsepower more than the outgoing "Blue Flame" inline-six Corvette engine. The small-block Chevy was produced with many different combinations of bore and stroke over its six decade lifespan, all the way up to a 400 cubic inch displacement for trucks and vans. Ironically, a 400 cubic inch small-block is actually larger than some so-called big-blocks, such as Chrysler's 383 or Chevy's own 396. However, the most well known iteration of the small-block is the 350, or 5.7-liter in metric terms. If you've been in the car hobby for any reasonable amount of time, the chances are that you've interacted with a 350-powered vehicle on some level. In fact, some sources call it "America's favorite V8." Read more: These V6 Engines Put The LS1 V8 To Shame By 1997, the writing was on the wall for the venerable small-block Chevy. That's the year when the first LS-based V8 engine debuted in the brand-new fifth-generation Corvette C5, sarcastically reviewed here by Mr. Regular. There's a bit of friendly debate among enthusiasts as to whether LS motors are truly considered part of the small-block Chevy family or a separate entity. Besides obvious differences like the lack of a conventional distributor, the LS even has a different firing order than its predecessors. For the record, General Motors says that the LS is a continuation of the small-block lineup. However, the fact remains that the LS shares very little in common with the first- and second-generation small-block V8, which was fully phased out of production vehicles by the end of 2002. More than 100 million small-block Chevys engines have been produced so far, plus it continues to be offered to this day in "crate engine" form. Like its sibling, the 3.8-liter V6, the small-block Chevy powered a wide array of vehicles from GM's assembly line. That includes Corvettes, Camaros, pickup trucks, and grocery-getter sedans and wagons. What's more, many of those engines went on to live a second life after their original host vehicles went to the crusher. Small-block Chevys have been swapped into all manner of vehicles including Jeeps and Ford hot rods from the 1930s, heck, there's even a Chevy-powered 1970 Porsche 911. In part, that's because of the tremendous aftermarket support and the seemingly limitless supply of repair and upgrade parts available. With over 100 million examples floating around, we wouldn't expect any less. Want more like this? Join the Jalopnik newsletter to get the latest auto news sent straight to your inbox...

EV U.S. Sales Lag Will Reprieve ICE, Boost Hybrids
ICE versus EV getty Every other new car bought by Americans in 2030 was supposed to be electric, but as the Trump Administration clears away EV incentives and targets, the total is likely to be less than half that and offer a lifeline to gas powered vehicles and hybrids That represents an unexpected new lease of life for the likes of GM , Ford, and Stellantis brands like Chrysler, Dodge, Jeep and Ram and their combustion technology. They were highly dependent on internal combustion engines and were either slow or reluctant to embrace EVs. A combination of tax credit rollbacks, emissions standards delays and the removal of the Biden Administration and its call for a 50% share for EVs in the new car market in 2030 is a boost for ICE. Manufacturers will also be busily raising production of hybrids, plug-in hybrids, and extended range electric vehicles*. Consultants Roland Berger put it this way in a recent report. 'Delayed adoption of BEVs (EVs) will have cascading effects on the entire automotive value chain, prolonging profitability challenges for electrification-focused players and extending the window of opportunity for ICE-focused legacy players,' the report said. Analysts have been scrambling to slash their forecasts for U.S. EV sales in 2030. Investment bank UBS says EVs will only reach 24% of the new car market or 2.7 million vehicles. Four months ago UBS was predicting 32%. U.S. EV market share is currently around 10%. BloombergNEF now predicts 27%, down from almost 48%. Investment researcher Jefferies is even lower at about 20% along with Roland Berger. Roland Berger was projecting around 40% under Biden's watch. 'Actions taken by the Trump administration to loosen light vehicle emissions standards have effectively halved our forecast for U.S. electric vehicle adoption by 2030 – We now only expect about 20% BEV sales by 2030,' said Brandon Boyle, Senior Partner and Americas Automotive lead at Roland Berger. This compares starkly with Europe's ambitions. The European Union has decreed EV sales shall reach about 80% of new vehicle sales by 2030 on the way to 100% by 2035. Given current market share is barely 20% in Europe, some major humble-pie eating is on the cards. The Mazda MX-30 R-EV is an extended range electric vehicle equiped with a small rotary gasoline ... More engine (Photo by Sjoerd van) Getty Images / Sjoerd van der Wal 'The U.S. market has different dynamics (than Europe): more rural driving, less dense urban cores, and a political environment that could shift depending on the 2028 (Presidential) election,' said Curt Hopkins, CEO of MCQ Markets . MCQ Market says it is a FinTech firm making high-value assets accessible and investable. 'I wouldn't call it a comeback for ICE, but it's not going away overnight either. Hybrids and plug-in hybrids are still very much part of the transition-especially for consumers who aren't quite ready for a full battery-electric experience. Expect those to play a meaningful but gradually shrinking role through the decade,' Hopkins said. Bernstein Research analyst Daniel Roeska said at some point EV demand will accelerate again. Maybe after the 2028 election or after 2030. 'It (the expectation) won't be 50% for a long while,' Roeska said in an interview. '(General Motors, Ford and Stellantis) agreed that U.S. electrification will take a lot longer. Even if the target picture of high EV share in the U.S. has not changed, (manufacturers) are waking up to the fact that they must improve EV profitability without significant volume growth and maintain investments into legacy products for longer,' Roeska said in a recent report. Hard to bet against Tesla Tesla is the current EV market leader and despite a huge increase in competition and lower expectations for the overall market, is expected to retain its ascendancy, said MCQ's Hopkins. 'It's hard to bet against Tesla. They're vertically integrated, have a dominant brand, and continue to lead on software and over-the-air updates. As long as they maintain that pace of innovation, they'll likely still be the U.S. leader in 2030,' said Hopkins. According to Kelley Blue Book , the Tesla Model Y led the U.S. EV market in 2024 with sales of 373,000 and a market share of 28.6%, the Tesla Model 3 was next with 190,000 (14.6%). Then came the Ford Mustang Mach-E with 52,000 or 4.0%. 'That said, keep an eye on some dark horses. Chinese automakers like BYD and NIO are getting serious about international expansion, and if trade policy allows, they could become a factor in the U.S. by the end of the decade.' The All-Electric Ford Mustang Mach-E (Photo by) Getty Images 'Among the legacy automakers, Ford, GM, and Volkswagen have all shown real progress. Their ability to scale EV production and leverage existing dealer networks could help them close the gap, especially as more affordable models hit the market,' according to Hopkins. Twice the power, half the weight, half the cost He doesn't expect any game-changing battery technology before 2030, just incremental improvements in battery design. The long- promised solid-state battery revolution – twice the power, half the weight, half the cost - isn't close as researchers stumble over mass production techniques. And the trouble is that as consumers hear about this huge, imminent improvement, they are likely to be wary of buying an EV, and risk having its residual value torpedoed by game-changing technology. That could put the skids on EV demand as 2030 approaches. More bad news for EV makers came this week, courtesy of a survey of 15,000 drivers around the world by oil-giant Shell. The survey showed drivers in America are becoming more reluctant to switch to EVs from ICE vehicles. Those considering switching fell three percentage points to 31% compared with a year ago. In Europe, the reluctance was more ominous given the massive EV targets set for 2030. According to the survey, 41% said they would consider switching to an EV, down from 48% last year. Shell operates 75,000 charging points around the world including the U.S., Europe and China. *(Hybrids use computer power to combine for maximum efficiency with gasoline engines, and have relatively small batteries. They provide maybe 1 mile of electric-only driving. PHEVs have bigger batteries which can be charged independently and can provide up to 75 miles of electric-only transport. EREVs, like the Mazda MX30 R-EV, use small combustion engines to charge the battery. The MX30 R-EV is always powered by electricity.)
