On August 20, 2026, federal regulators opened another investigation into Chevy 6.2 engine issues. This time, they’re looking at whether GM’s recall repair got the job done. Hundreds of owners said their engines failed after getting the fix. Some even got new engines and still had trouble.
Did you get a recall notice? Go through the fix, only for warning lights to come back? Lose your engine on the road? You’re not imagining it. Here’s a steady look at the defect, recall, federal investigation, class action, and your options under California lemon law. Each story is different. You may have rights to a buyback, replacement, or cash. That’s apart from any class action.
Is Your Truck or SUV Affected by the Chevy 6.2 Engine Problem?
The GM 6.2L L87 V8 sits under the hood of some 2021–2026 Chevrolet, GMC, and Cadillac trucks and SUVs. Think Silverado, Tahoe, Suburban, Sierra, Yukon, Escalade. The first recall focused on 2021–2024. The 2026 investigation covers 2021–2026.
Wonder about your vehicle? Check your VIN. Look at any recall letters. Review your dealer’s paperwork. Not sure? Ask your dealer or use NHTSA’s site to check your VIN. It’s worth knowing for sure.
Which Models Get Hit?
- Chevrolet Silverado 1500
- Chevrolet Tahoe
- Chevrolet Suburban
- GMC Sierra 1500
- GMC Yukon and Yukon XL
- Cadillac Escalade and Escalade ESV
Does Model Year Matter?
Yes. The rules change by year.
- Original recall (25V-274): 2021–2024
- 2026 Engineering Analysis: 2021–2026
If you have a 2025 or 2026, you may still need answers. If your truck has the L87 and engine troubles, you’re not outside the circle.
What Engine Problems Are Owners Reporting?
Most stories come down to broken parts deep inside: connecting rods and crankshafts. The parts wear out, damage bearings, and sometimes leave you stranded. GM and NHTSA point to damage from contamination and out-of-spec parts.
What if this happens while driving fast or towing? It’s a safety question.
How Connecting Rod Damage Happens
Contamination gets in. Bearings get damaged. Wear builds. Knocking or ticking may start. Then the engine fails.
You can’t see this inside. No obvious signs until things get worse. Does that sound familiar?
Crankshaft Problems and Engine Seizure
Some crankshafts are out of spec. That wears parts down over time. Let it go too far, and the engine may seize. That means your truck won’t move on its own.
What’s the Main Risk for Owners?
When an engine cuts out, it’s a risk. On the freeway. While towing. You lose trust in a truck you count on.
What are the signs?
- Engine knocks or ticks
- Check-engine or oil-pressure warnings
- Metal in your oil
- Rough running or stalling
- Sudden engine failure
What Does the GM Recall Actually Do?
GM recall 25V-274 covers about 597,630 vehicles from 2021–2024 with the 6.2L L87 V8. It’s about damaged connecting rods and crankshafts that might fail. NHTSA issued the recall in April 2025, covering parts made from March 1, 2021 through May 31, 2024.
Official records are in NHTSA’s recall database. If you’ve had repairs and need lemon law answers, our General Motors lemon law page is set up for California owners.
How Dealers Go About the Repair
- First, your engine’s inspected.
- If it fails inspection, you get a new engine.
- If it passes, no new engine—just a tweak.
What’s With the 0W-40 Oil?
If your engine passes, the fix is simple. Dealers put in thicker 0W-40 oil, swap the filter and cap. Many owners ask, will that work?
Ten Years or 150,000 Miles—What’s That Mean For You?
GM extends your warranty. Ten years or 150,000 miles if you got the lighter fix. Only about 3% of trucks got a new engine. The rest just got the oil switch.
But a longer warranty doesn’t fix lost time, worry, or trust issues when your truck keeps acting up. You know what matters most is reliability.
Why Are Regulators Watching the Recall?
NHTSA took notice because so many engines kept failing after the recall. Simple as that. Some trucks got the 0W-40 oil. Others even got a full new engine. Failures happened again.
What Happens in an Engineering Analysis?
It’s a closer look. Not every truck is bad. But it pulls the spotlight on GM. EA26005 opened August 20, 2026, now covers almost a million vehicles built from 2021–2026 with the 6.2L L87.
What Are the Complaint Numbers?
- 499 reports of engine failure after the recall repair
- 473 had the 0W-40 oil done
- 26 received a full engine replacement
- 191 came from L87 engines built outside the recall range
- That’s 690 new cases to check
Is the Fix Enough?
Many drivers, along with their lawyers, doubt that thicker oil solves a core defect. Failures sometimes show up right after leaving the shop.
These are questions, not proven facts. That’s the point of the investigation. We’ll know more as things go on.
Is There a GM L87 Class Action? Does It Change Your Rights?
Yes. The GM L87 class action is in Michigan federal court. If you’re in California, you may still owe it to yourself to check different options. Multiple lawsuits were joined; now before Judge Kumar.
The big filing happened February 26, 2026, with a major law firm leading the charge (Houchin et al. v. General Motors LLC, No. 2:25-cv-11462). In June, GM argued it had already addressed the issue through the recall and warranty.
What’s the Lawsuit About?
It’s about the defect, how soon GM knew, and whether the recall or warranty is enough, since engines kept failing. The group’s looking for relief for owners or people who leased. No result is guaranteed.
Is a Class Action Your Best Bet?
They run for years. Recovery can be small, often not tailored for your actual experience.
California lemon law is more direct. It’s built around your story, your fix attempts, your damages.
Can California Lemon Law Help With Chevy 6.2 Engine Issues?
Yes, it can. If your Chevy 6.2 had engine problems under warranty and GM or its dealers couldn’t fix it after a reasonable number of tries, you’ve got options. The Song-Beverly Consumer Warranty Act is there so you don’t have to stick with a broken vehicle.
What counts as “reasonable” depends on your story. Many repairs, recurring symptoms, and long waits at the shop all matter. Our page on lemon law requirements keeps it simple.
What Patterns Qualify?
- Several repairs for the same engine problem
- Recall repair, then symptoms return
- Engine replacement, then fresh trouble
- Long waits for parts or dealer approvals
What Do Owners Actually Get?
- Buyback: Turn in your truck, recoup payments and price, less any mileage use. Use our buyback calculator to get a sense of value.
- Replacement: Sometimes, a similar model is offered.
- Cash: Keep your truck, get a cash settlement for the trouble.
Everyone’s outcome depends on facts. No two claims are alike.
Are Penalties Available?
Yes, sometimes. If a manufacturer willfully doesn’t follow the rules, California can allow extra damages up to twice your actual loss. It’s rare and fact-specific. Not automatic.
How Much Does Legal Help Cost?
We charge you nothing up front. If you win, GM pays the legal bill. That means you don’t risk your own money to make your voice heard. That’s our policy.
What Should You Do If Your Engine Keeps Failing?
Keep records of every repair. Think about safety. Save paperwork. Talk to a California lemon law attorney before you decide the recall fix is your only path. Good records help your claim. That’s three basics.
What Should You Keep?
- Repair orders
- Recall notices
- Inspection records
- Warranty info
- Purchase or lease paperwork
- Tow or rental receipts
What Symptoms Matter?
Don’t brush off any of these:
- Knocking or ticking noises
- Check-engine light
- Oil-pressure warnings
- Metal in oil
- Stalling
- Sudden loss of propulsion
- Engine seizure
Return to a GM dealer while your warranty is live. Get repair orders in writing, not just words at the counter. Our guide on how to file a lemon law claim walks through it.
When Should You Get Legal Help?
- After a first serious engine issue
- After repeat dealer trips
- If the recall repair failed
- After engine replacement or seizure
- If you’re just not sure where you stand

Answers to Common Questions
Does California lemon law help with leased Chevy, GMC, or Cadillac vehicles?
Yes. If you leased your vehicle in California and warranty repairs didn’t fix the defect, your lease and repair facts affect your options.
Do I have to wait for another repair to call a lawyer?
No. You can reach out after the first serious engine concern. It helps to see what steps to take and what to save early on.
What’s my Chevy 6.2L truck or SUV worth as a lemon?
It depends. Purchase or lease terms, payments, miles, repair record, and penalties all shape value. A quick review gives you a realistic sense.
Will GM pay my lemon law legal fees?
If your claim is successful, GM pays your lemon law attorney fees. That’s why it’s free for you.
My 2025 or 2026 truck wasn’t in the first recall. Does that matter?
It could. The 2026 federal investigation looks at 2021–2026 models with the 6.2L L87—even those built after the original recall range.
