The Heartbreak of the 100k Mark: A Chevrolet Silverado Story
For many truck owners, reaching 100,000 miles is a rite of passage—a milestone that proves a vehicle’s durability. However, for one Chevrolet Silverado Trail Boss owner, the journey ended just short of the finish line. At 98,876 miles, his 6.2-liter V8 engine finally gave out, leaving him stranded and his truck on a flatbed.
While a sudden engine failure is a nightmare for any driver, this specific case highlights a much larger issue affecting thousands of GM vehicles. This isn’t just a case of “bad luck”; it’s a symptom of a widespread manufacturing defect that has led to a massive recall.
The L87 Engine Recall: What’s Actually Happening?
General Motors has issued a significant recall for certain 2021–2024 Chevrolet Silverado 1500s equipped with the 6.2-liter L87 V8 engine. This issue isn’t limited to the Silverado; it also affects the GMC Sierra 1500, Chevrolet Tahoe, Suburban, GMC Yukon, and Cadillac Escalade.
According to official documentation filed with the NHTSA (National Highway Traffic Safety Administration), the root cause lies in manufacturing defects involving the connecting rod and/or crankshaft. When these components fail, it can lead to catastrophic engine damage, loss of propulsion, and a significantly increased risk of accidents while driving.
The Silver Lining: A Generous (But Complex) Warranty
To mitigate the fallout, GM has established a special coverage bulletin. If your engine fails due to this specific crankshaft/connecting rod condition, it is covered for 10 years or 150,000 miles, whichever comes first.
However, there is a crucial detail owners must understand: This warranty is tied to the vehicle’s original in-service date. It is not an additional 150,000 miles starting from the day you get a replacement engine. For the owner who failed at 98k miles, he still had over 50,000 miles of coverage left—but that doesn’t make the wait any easier.
The Reality of the Repair Process
Getting a replacement isn’t as simple as driving into a dealership. GM’s current protocol involves:
- n
- Inspection: Dealers inspect affected vehicles to determine if a replacement is necessary.
- Preventative Maintenance: Vehicles that pass inspection are often given higher-viscosity 0W-40 oil and a new oil-fill cap.
- Engine Replacement: For those that fail, a new (or sometimes remanufactured) engine is ordered.

The biggest frustration for owners today? Backorders. Many drivers report that while GM has approved the replacement, the engines are not readily available, leaving high-value trucks sitting useless in dealership lots for weeks or even months.
Reliability Debate: New Tech vs. Old School Steel
This recall has sparked a heated debate among the truck community. While some newer 6.2L engines are failing prematurely, longtime GM loyalists point to the legendary 6.0L V8s of the past, with some reporting over 350,000 miles of heavy-duty towing without a single major failure.
This disparity is leading some owners to question if modern engineering has traded long-term durability for short-term performance. From reports of 5.3L engines seizing at 3,000 miles to the 6.2L recall, the perception of Chevrolet Silverado reliability is currently under heavy scrutiny.
What Should You Do If You Own a 6.2L Silverado?
- Check Your VIN: Visit the official Chevrolet owner center to see if your specific vehicle is part of the recall.
- Monitor Performance: Be alert for any unusual engine noises or loss of power.
- Document Everything: If you perform oil changes independently, keep detailed records and photos to ensure your warranty claims aren’t denied.
