The National Highway Traffic Safety Administration (NHTSA) has launched a federal investigation into potential engine failures in Chevrolet trucks and SUVs built between 2019 and 2024. The issue, which affects vehicles equipped with the 6.2-liter L87 V8 engine, may be linked to connecting rod bearing failures, which can cause severe engine damage.
With over 877,000 vehicles potentially at risk, this investigation could lead to a massive recall affecting popular models like the Chevy Silverado, GMC Sierra, Chevy Tahoe, GMC Yukon, and Cadillac Escalade. While no injuries or accidents have been reported so far, dozens of complaints have been filed with the NHTSA regarding abrupt engine failure, some involving broken connecting rods puncturing the engine block.
If your Chevrolet or GMC truck or SUV has experienced engine problems, loss of power, or sudden breakdowns, it is critical to understand your legal options. At The Barry Law Firm, we specialize in helping consumers who have been sold defective vehicles. If your vehicle has suffered repeated repairs for engine-related issues, you may be entitled to a refund, replacement vehicle, or financial compensation under California’s Lemon Law.
What’s Wrong with Chevrolet’s 6.2-Liter L87 Engine? 
The 6.2-liter L87 V8 engine, a powerful and widely used engine across Chevrolet, GMC, and Cadillac models, has become the subject of an NHTSA investigation due to numerous reports of catastrophic engine failure. Owners have complained of abrupt loss of power, loud knocking noises, and complete engine failure, sometimes while driving at highway speeds.
The primary issue appears to stem from defective connecting rod bearings, which are crucial for engine function. These bearings are designed to reduce friction between moving parts, allowing the engine’s pistons to operate smoothly. However, in the affected vehicles, these components are failing prematurely, leading to severe mechanical damage.
Why Are the Connecting Rod Bearings Failing?
The exact cause of the failure is still under investigation, but preliminary reports suggest that the bearings may have been improperly manufactured or installed, leading to insufficient lubrication, excessive friction, and rapid wear. When these bearings fail, they can cause:
- Excessive heat buildup – Lack of lubrication can lead to overheating, increasing the risk of failure.
- Rod separation – A failed bearing can cause the connecting rod to break loose, resulting in catastrophic engine damage.
- Block puncture – In severe cases, the connecting rod can break through the engine block, rendering the engine irreparable.
Warning Signs That Your Engine May Be Failing
If you own a Chevrolet, GMC, or Cadillac with the 6.2-liter L87 V8 engine, it is important to watch for these warning signs:
- Loud knocking or ticking noises from the engine
- Sudden and complete loss of power
- Excessive oil consumption
- Metallic debris in the engine oil
- Check engine light illuminated
- Smoke or burning smell from the engine
Some drivers have reported experiencing engine failure without warning, leaving them stranded and in need of a full engine replacement. If you notice any of these symptoms, do not ignore them—seek immediate service from a General Motors dealership.
However, if your vehicle continues to experience engine failure despite a reasonable number of repair attempts, you may be entitled to compensation under California’s Lemon Law.
Which Vehicles Are Affected?
The NHTSA’s investigation covers Chevrolet, GMC, and Cadillac vehicles manufactured between 2019 and 2024 that are equipped with the 6.2-liter L87 V8 engine.
Potentially Affected Models:
- Chevrolet Silverado
- GMC Sierra
- Chevrolet Tahoe
- GMC Yukon
- Chevrolet Suburban
- GMC Yukon XL
- Cadillac Escalade
While 877,000 vehicles are under investigation, this number could increase if further defects are discovered.
Even if your vehicle has not yet experienced engine failure, it may still be at risk. If you drive one of these models, you should monitor your vehicle for any signs of performance issues and seek immediate repairs if necessary
What Is General Motors Doing About the Issue?
At this time, General Motors has not issued a recall for the affected vehicles. Instead, the company is cooperating with the NHTSA investigation while gathering data on how widespread the problem is.
GM’s Response So Far:
- GM has acknowledged the issue and is monitoring customer complaints.
- The company has not committed to offering extended warranties or automatic repairs for affected owners.
- GM is encouraging drivers to report problems to the NHTSA and visit dealerships for service if they notice engine performance issues.
Why Hasn’t GM Issued a Recall?
Automakers often delay recalls until they are legally required to take action. By waiting for the NHTSA’s findings, GM is likely trying to avoid the financial and reputational consequences of a major recall. However, if the investigation determines that engine failure poses a significant safety risk, a recall may be unavoidable.
If GM does not take action soon, affected vehicle owners may have to pursue legal options to receive compensation for engine repairs, replacements, or buybacks.
If your vehicle has experienced engine failure or repeated repairs, don’t wait for GM to act—know your rights under California’s Lemon Law.
What If Engine Issues Persist After Repairs?
If your Chevrolet or GMC truck or SUV has already undergone multiple repairs for engine-related issues but continues to experience problems, you may have a Lemon Law claim under California’s consumer protection laws.
Common Problems That May Continue After Repairs
Even after multiple dealership visits, some Chevrolet, GMC, and Cadillac owners continue to experience persistent engine issues, raising concerns about the effectiveness of the repairs performed under warranty or recall programs. While dealerships may attempt to replace damaged components or perform software updates, these repairs do not always address the root cause of the problem. Many vehicle owners report that their trucks or SUVs begin experiencing the same symptoms again within weeks or months of a repair, leaving them frustrated, without reliable transportation, and stuck in a cycle of endless service appointments.
One of the most frequently reported issues is recurring engine knocking or ticking noises, which may indicate ongoing internal engine damage. This sound, which often originates from the bottom end of the engine, could be a sign that the connecting rod bearings are still experiencing excessive wear and friction, even after an attempted fix. In many cases, these noises are an early warning sign of imminent engine failure, meaning that a vehicle that has already been “repaired” could still be on the verge of another breakdown. Some drivers also report that the engine runs rough or vibrates excessively, making the vehicle difficult to drive smoothly.
Another major concern is the check engine light repeatedly illuminating, sometimes just days after a repair. While technicians may clear the error codes and claim the issue has been resolved, a persistent check engine light often signals that the engine is still not functioning properly. These warnings may indicate ongoing problems with fuel delivery, emissions systems, misfires, or internal mechanical damage. In some cases, owners have been told by dealership service departments that the check engine light is “normal” or that there is nothing more they can do until a complete failure occurs. This approach is not only frustrating for consumers but also potentially dangerous, as continuing to drive a vehicle with unresolved engine defects can lead to catastrophic breakdowns.
Many affected vehicle owners have also reported sudden loss of power or failure to accelerate, especially at highway speeds or when attempting to merge into traffic. This issue is particularly concerning because it can create serious safety hazards, increasing the risk of collisions. Some vehicles experience hesitation and jerking movements before stalling, while others may completely shut off without warning, leaving drivers stranded. In some cases, the dealership may attribute the problem to software issues or minor sensor malfunctions, but if the underlying engine defect has not been fully addressed, these symptoms will continue to occur.
Another persistent problem that often remains even after multiple repairs is oil leaks or excessive oil consumption. A properly functioning engine should maintain a consistent oil level between service intervals, but some Chevrolet, GMC, and Cadillac owners have reported losing quarts of oil between changes, sometimes as frequently as every 1,000 miles. This excessive oil consumption is not only costly but also an indicator of serious internal wear, potentially leading to low oil pressure, overheating, and premature engine failure. Some engines also develop oil leaks at gaskets, seals, or the oil pan, which can worsen over time and lead to further mechanical complications.
Perhaps the most severe issue that continues to affect some owners despite previous repair attempts is total engine failure requiring full replacement. Many consumers have repeatedly brought their trucks and SUVs into dealerships for service, only to experience complete engine shutdowns again and again. Some vehicles suffer catastrophic damage, with broken connecting rods puncturing the engine block, making repairs impossible. When this happens, a full engine replacement is the only option, a costly and time-consuming process that leaves many owners wondering whether their vehicle will ever be reliable.
If your Chevrolet, GMC, or Cadillac truck or SUV has been repaired multiple times for the same engine problems, yet the issues keep coming back, you may have a lemon.
