General Motors is facing a proposed class action lawsuit alleging that several Chevrolet, GMC and Buick vehicles can develop coolant leaks because of defective radiator hose connectors. The complaint claims the problem can occur relatively early in a vehicle’s life and may lead to engine damage and unexpected repair costs.

What is the problem?

The lawsuit covers 2023-2026 Chevrolet Colorado and GMC Canyon trucks equipped with the L3B 2.7-liter turbocharged four-cylinder engine. It also includes 2024-2026 Chevrolet Traverse, 2024-2026 GMC Acadia, and 2025-2026 Buick Enclave models fitted with the LK0 2.5-liter turbocharged four-cylinder engine.

According to the complaint, the vehicles use sealed cooling systems designed to circulate coolant between the engine and radiator. However, the lawsuit alleges that the quick-connect fittings on the radiator hoses can fail prematurely, allowing coolant to escape, causing the engine to run without sufficient fluid to regulate its temperature. If the problem is not detected quickly, the lawsuit claims it can result in overheating and potentially serious engine damage.

The case was brought by a Georgia owner of a 2024 Chevrolet Colorado who says his check engine light came on at around 44,400 miles. A dealership reportedly diagnosed a coolant leak from the upper radiator hose connector and identified a P3075 trouble code. The owner says he was charged $489.36 for the repair.

The lawsuit also points to a GM service bulletin issued in March 2026 concerning upper radiator hose connector seal failures on Colorado and Canyon trucks. The plaintiff alleges that GM’s coverage did not extend to his vehicle because it was beyond the three-year/36,000-mile bumper-to-bumper warranty.

What owners should do

Owners of the affected models should watch for warning lights, low coolant levels, unusual engine noises or signs of overheating. Anyone experiencing these symptoms should arrange an inspection with a GM dealership.

Keep copies of repair invoices, diagnostic reports and communications with GM, especially if a coolant leak has already resulted in an expensive repair or the problem has returned.

How GM owners can take back control

A cooling-system problem can become much more expensive if a small leak develops into engine damage. Owners who have already paid for repairs or are facing recurring coolant problems may want to understand whether they have options beyond simply covering another repair bill.

General Motors is facing a proposed class action lawsuit over allegations that certain Buick and Chevrolet vehicles contain a defective engine that can fail without warning, potentially causing a sudden loss of power and increasing the risk of an engine fire. The claims have raised concerns among owners who say they were left stranded by unexpected breakdowns and costly repairs.

What is the problem?

The lawsuit involves certain 2024 and newer Chevrolet Trax and Trailblazer models, along with the Buick Encore GX and Buick Envista, equipped with a 1.2-liter turbocharged three-cylinder engine. According to the complaint, the engines may contain defects that can lead to catastrophic failure, fluid leaks, and in some cases, engine-compartment fires.

Plaintiffs claim the defect can cause vehicles to lose motive power unexpectedly, creating a particularly dangerous situation if it occurs at highway speeds or in heavy traffic. A sudden loss of acceleration or power can leave drivers with little time to react and may significantly increase the risk of a collision.

The lawsuit also alleges that GM was aware of the issue through consumer complaints and internal reports but failed to adequately disclose the alleged defect to buyers. According to the complaint, the manufacturer issued technical service bulletins to dealerships but has not provided a permanent solution for affected owners.

What owners should do

Drivers who experience warning lights, unusual engine noises, fluid leaks, or a sudden loss of power should arrange an inspection as soon as possible. Owners should also keep records of repair invoices, dealership visits, and any communications with GM in case problems persist.

Consumers may also wish to monitor developments in the proposed class action and stay informed about any future recalls, warranty extensions, or service campaigns related to the affected engines.

How GM owners can take back control

When serious defects continue despite repair attempts or manufacturers fail to provide satisfactory answers, understanding your rights can be an important step forward.

A new class action lawsuit investigation is focusing on General Motors over allegations that certain vehicles equipped with 6.2L V8 engines may suffer from serious engine defects that can lead to sudden failure.

What’s the Class Action About?

The investigation centers on GM’s 6.2L V8 (L87) engine, which is alleged to contain internal defects that can cause catastrophic engine failure without warning. Affected drivers report sudden stalling, loss of power, and in some cases, concerns over potential fire risks.

The claims suggest that key engine components—such as crankshafts and connecting rods—may be prone to failure, leading to unsafe driving conditions. Sudden power loss, particularly at speed, can significantly increase the risk of a crash.

Attorneys involved in the investigation also argue that GM may have been aware of these issues but failed to adequately disclose them or provide a lasting fix.

Which GM Models Are Affected?

The proposed class action includes drivers who owned or leased 2021–2025 GM vehicles equipped with the 6.2L V8 engine. Affected models may include:

• Cadillac Escalade
• Chevrolet Silverado 1500
• Chevrolet Suburban
• Chevrolet Tahoe
• GMC Sierra 1500
• GMC Yukon
• GMC Yukon XL

These vehicles are among GM’s most popular trucks and SUVs, making the potential scope of the issue significant.

What Compensation is Being Sought?

The lawsuit investigation is seeking compensation for affected owners and lessees, including reimbursement for repair costs, engine replacements, and losses related to diminished vehicle value.

Drivers may also be eligible for compensation related to repeated repair attempts, extended time without their vehicle, or safety risks associated with unexpected engine failure.

Why You Should Consider Opting Out

While class actions can provide some level of compensation, they often result in lower payouts per individual. Drivers who have experienced serious issues—such as repeated breakdowns, safety concerns, or significant repair costs—may benefit from pursuing an individual claim instead.

Opting out of a class action allows your specific situation to be evaluated independently, which can lead to a more favorable outcome.

How GM Owners Can Take Back Control

While this class action lawsuit has been initiated, thousands of GM owners are likely affected by the same engine defect, with many expressing dissatisfaction over GM’s inadequate solutions. These types of issues often lead to escalated legal action, highlighting the importance of protecting consumer rights.

History Behind the Lawsuit

A new class action lawsuit has been filed against General Motors (GM), alleging that several of its 2025 model-year vehicles contain defective master brake cylinder assemblies that can lead to a partial or total loss of braking ability.

The lawsuit, Barron, et al. v. General Motors LLC (Case No. 2:25-cv-05696), was filed on October 2, 2025, in the U.S. District Court for the Eastern District of Pennsylvania by plaintiffs Eric Barron and Chelsey Thompson. They claim GM violated state and federal consumer protection laws by selling vehicles that are unsafe to drive and failing to repair the defect under warranty.

According to the complaint, the alleged defect causes the brake pedal to become either stiff and difficult to press or sink to the floor, often accompanied by warning lights and a “Service Brake System” message on the dashboard. Owners say the issue occurs suddenly, sometimes shortly after purchase.

Claims Made by the Plaintiffs

The plaintiffs allege that GM knew about the defect before selling the affected vehicles, citing pre-sale testing data, customer complaints, and dealership reports. Despite this, the company allegedly failed to issue a recall or provide timely repairs.

Vehicles named in the lawsuit include the 2025 Chevrolet Traverse, GMC Acadia, Buick Enclave, Chevrolet Colorado, and GMC Canyon. The plaintiffs claim these vehicles share the same faulty master cylinder design, which can cause abrupt brake failure.

Drivers reportedly attempted temporary fixes such as restarting the vehicle or pumping the brake pedal, but these methods offer no permanent solution.

The lawsuit seeks class certification, monetary damages, reimbursement for repairs, and a jury trial, citing fraudulent concealment, breach of warranty, and violations of state lemon and consumer protection laws.

What GM Owners Should Do Next

Owners of 2025 GM vehicles listed in the lawsuit should document all brake-related issues, including warning lights, service messages, and dealer visits. Keeping repair invoices and communication records could support future claims or reimbursement if the lawsuit expands or leads to a recall.

How GM Owners Can Take Back Control

While this class action lawsuit has been filed, many owners nationwide may be affected by similar issues. These problems often escalate into large-scale legal actions, making it vital for consumers to stay informed and protected.

History Behind the Investigation

The National Highway Traffic Safety Administration (NHTSA) has opened a new engineering analysis into certain General Motors SUVs and trucks over reports of engine failures that may extend beyond GM’s previous recall.

The issue, described by regulators as “loss of motive power due to engine failure,” centers on vehicles equipped with 6.2-liter V8 gasoline engines. According to NHTSA’s Office of Defects Investigation (ODI), the failures may result from manufacturing defects in the connecting rod and crankshaft, which can cause sudden engine seizure and stalling while driving, posing a serious crash risk.

GM previously issued a recall in April 2025, covering approximately 721,000 vehicles from the 2021–2024 model years, including Cadillac Escalade, Chevrolet Silverado 1500, Suburban, Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL models.

However, NHTSA has since received more than 1,100 additional complaints of engine failures from owners whose vehicles were not included in GM’s recall, prompting this new round of scrutiny.

Vehicles Under Investigation

The current investigation covers roughly 286,000 vehicles that were part of the original inquiry but excluded from GM’s voluntary recall.

According to NHTSA’s October 23 report, the vehicles under investigation include:

• 2019–2024 Chevrolet Silverado 1500
• 2019–2024 GMC Sierra 1500
• 2021–2024 Chevrolet Suburban
• 2021–2024 Chevrolet Tahoe
• 2021–2024 GMC Yukon / Yukon XL
• 2021–2024 Cadillac Escalade / Escalade ESV

The ODI report notes that 173 of the 1,157 engine failure complaints involve vehicles outside GM’s original recall (identified internally as 25V-274). The agency said this trend represents a potential safety risk that “warrants further investigation.”

GM has acknowledged the issue stems from supplier quality problems and says it is cooperating fully with regulators. The automaker has also reported 12 minor injuries and 12 alleged crashes potentially linked to the defect, though most incidents were not crash-related.

What GM Owners Should Do Next

At this time, the investigation remains open and no new recalls have been announced. However, affected owners should take precautionary steps:

• Contact a GM dealer to verify if their vehicle is part of any recall or inspection campaign.
• Report symptoms such as knocking noises, loss of power, or sudden stalling to NHTSA at nhtsa.gov/vehicle-complaint .
• Check recall status using their Vehicle Identification Number (VIN) at nhtsa.gov/recalls .

During the prior recall, GM advised dealers to inspect engines and replace them if damage was found. Vehicles that passed inspection received higher viscosity engine oil, a new oil cap, and a replacement oil filter to help prevent failure.

How GM Owners Can Take Back Control

While this investigation has started, no official recalls have been announced yet. Many owners continue to be unhappy with the solutions provided by automakers. These problems have the potential to escalate into further action, underlining the importance of protecting consumer rights.

History Behind the Recall

General Motors has announced a safety recall for 1,191 vehicles from its 2026 Chevrolet Silverado EV and GMC Sierra EV lineups due to a problem with the electronic stability control (ESC) warning system.

Filed under NHTSA Campaign Number 25V594000, the recall notes that following an ESC system malfunction, the warning light may fail to illuminate during the next ignition cycle. This means drivers could be unaware of a stability control issue, increasing the risk of a crash.

The defect also causes affected models to violate Federal Motor Vehicle Safety Standard (FMVSS) No. 126, which governs ESC systems and their required warning functions.

Which Vehicles Are Affected?

• 2026 Chevrolet Silverado EV
• 2026 GMC Sierra EV

These two all-electric pickup trucks are among GM’s newest models, representing the brand’s move toward an electric future. Despite being technologically advanced, this early production defect shows that even EVs aren’t immune to traditional compliance issues.

What Owners Need to Do Next

GM will update the Electronic Brake Control Module (EBCM) software either over-the-air (OTA) or at dealerships free of charge. Owner notification letters are scheduled to be mailed on October 27, 2025.

Owners can contact:

• Chevrolet Customer Service: 1-800-222-1020
• GMC Customer Service: 1-800-462-8782 and reference recall number N252515340.

How GM Owners Can Take Back Control

While this recall has been communicated to owners, many continue to be unhappy with the solutions provided by automakers. These problems have the potential to escalate into further action, underlining the importance of protecting consumer rights.

History Behind the Recall

General Motors (GM) has issued a new safety recall affecting a small number of its full-size SUVs after identifying a potential fuel leak hazard. According to the National Highway Traffic Safety Administration (NHTSA), the issue involves replacement fuel tanks that may have been incorrectly installed, increasing the risk of a fuel leak during a rollover crash.

The recall, filed under NHTSA Campaign Number 25V619000, applies to only 12 vehicles, but because the defect could lead to a fire if fuel escapes near an ignition source, the recall has been classified as a safety-critical issue.

Which Vehicles Are Affected?

The affected vehicles include:

• 2021 Cadillac Escalade
• 2021, 2023–2024 Chevrolet Tahoe
• 2022 and 2024 GMC Yukon

All recalled models are equipped with GM’s 6-cylinder diesel engine, and in each case, an incorrect replacement fuel tank may have been installed during prior service work.

What Owners Need to Do Next

GM dealers will inspect the vehicles to verify the correct fuel tank and replace it if necessary, free of charge.

Owner notification letters are expected to be mailed on November 3, 2025, and the affected VINs became searchable on NHTSA.gov as of September 18, 2025.

For assistance, owners can contact:

• Cadillac: 1-800-333-4223
• Chevrolet: 1-800-222-1020
• GMC: 1-800-462-8782

A new class action lawsuit has been filed against General Motors (GM), alleging that several of its most popular 2023 and 2024 full-size SUVs suffer from a critical safety defect affecting windshield wipers. Reports of wipers suddenly stopping working, leaving drivers unable to see in inclement weather.

What’s the Class Action About?

The complaint claims that an electrical defect in GM’s wiper system causes the blades to freeze or lock in place without warning, often halting mid-swipe across the windshield. Affected owners report that restarting the vehicle doesn’t fix the issue, and that the wipers may spontaneously begin working again after an unknown period of time, with no consistent way to trigger or repair the system.

Even more troubling, the defect allegedly does not trigger any diagnostic trouble codes, leaving GM technicians unable to pinpoint or document the problem. The lawsuit says this has led to numerous “no fault found” service visits, up to eight times in one owner’s case, without resolution.

Which GM Models Are Affected?

The proposed class action includes U.S. customers who leased or purchased the following 2023–2024 GM vehicles:

• GMC Yukon
• GMC Yukon XL
• Cadillac Escalade
• Cadillac Escalade ESV
• Chevrolet Suburban
• Chevrolet Tahoe

What Compensation is Being Sought?

The lawsuit accuses GM of selling unreliable and unsafe vehicles while failing to disclose the defect or provide a fix. Plaintiffs are seeking compensation for loss of vehicle use, reduced resale value, and breach of warranty.

Why You Should Consider Opting Out

While the class action may provide some relief, individual cases often result in far greater compensation, especially for owners who’ve experienced safety risks, canceled trips, and vehicle downtime. Opting out preserves your right to file your own claim and have your specific experience heard in full.

How GM Owners Can Take Back Control

While this class action lawsuit has begun, thousands of GM owners are likely to be affected by the same windshield wiper failure defect, with many expressing dissatisfaction over delayed or inadequate repairs. These types of issues often lead to broader legal action like this one, underscoring the importance of protecting consumer rights.
