The GM L87 engine lawsuit is one of the biggest auto defect cases heading into 2026. Thousands of GM truck and SUV owners say their 6.2L V8 engines failed prematurely because of defective lifters and a flawed cylinder deactivation system.
If your Silverado, Sierra, Tahoe, or Escalade started ticking, knocking, or lost power out of nowhere, you're not alone. Some owners have faced repair bills topping $5,000 before the vehicle even hit 50,000 miles.
This article covers every detail of the lawsuit as it stands in 2026. You'll find affected vehicles, eligibility rules, estimated payouts, settlement status, and exactly how to file a claim.
The case has gained serious traction in federal court. GM has fought hard to dismiss it. But the claims keep stacking up, and the pressure on GM to settle is growing by the month.
GM L87 Engine Lawsuit
The GM L87 engine lawsuit is a legal action against General Motors claiming the 6.2L V8 engine sold in many trucks and SUVs contains factory defects. Plaintiffs argue GM knew about lifter failures and valve train problems but sold the vehicles anyway.
The core allegation is straightforward. GM designed the L87 engine with Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems that deactivate cylinders to save fuel. Those systems put extreme stress on the hydraulic roller lifters, causing premature collapse.
| Detail | Info |
|---|---|
| Engine | 6.2L V8 (RPO Code L87) |
| Primary Defect | Hydraulic lifter collapse |
| Systems Involved | AFM and DFM cylinder deactivation |
| Legal Theories | Product liability, breach of warranty, consumer fraud |
| Jurisdiction | U.S. District Court, federal class action |
When a lifter collapses, the damage spreads fast. Bent pushrods, damaged camshafts, and scored cylinder walls follow quickly. Many owners report the engine going into "reduced power mode" without warning.
GM has acknowledged lifter issues through multiple Technical Service Bulletins (TSBs). But the company has consistently refused to extend warranty coverage or issue a recall for the root cause.
The lawsuit argues that GM's own internal testing showed these lifters were prone to failure. Selling the vehicles without disclosing this amounted to consumer fraud, according to the plaintiffs.
GM 6.2L L87 Engine Lawsuit Explained
The GM 6.2L L87 engine lawsuit centers on allegations that General Motors sold a defective powertrain in some of its most popular and expensive vehicles. The 6.2L V8 is the premium engine option, meaning buyers paid thousands extra for it.
Plaintiffs in the case come from multiple states. They claim GM violated state consumer protection laws, breached express and implied warranties, and committed fraud by concealment.
The lawsuit points to a specific mechanical chain of failure:
- Step 1: DFM or AFM system activates cylinder deactivation during normal driving
- Step 2: Hydraulic roller lifters cycle thousands of times beyond design limits
- Step 3: Lifter collapses or fragments internally
- Step 4: Metal debris circulates through the oil system
- Step 5: Camshaft, pushrods, and valve seats sustain secondary damage
The total cost of these cascading failures can reach $4,000 to $8,000 at a dealership. Some owners with out-of-warranty vehicles paid even more at independent shops.
What makes this lawsuit particularly strong is the paper trail. GM issued TSB #18-NA-355 and several updates addressing lifter noise and failure. These bulletins prove GM was aware of the problem, which is a critical element in fraud claims.
The plaintiffs argue GM should have recalled the vehicles. Instead, GM quietly adjusted its repair procedures while still marketing the L87 as a best-in-class engine.
GM L87 Engine Lawsuit Update 2026
As of early 2026, the GM L87 engine lawsuit remains active in federal court. The case has survived GM's motions to dismiss, and class certification proceedings are underway.
Several key developments happened in late 2025 and early 2026:
- October 2025: The court denied GM's second motion to dismiss fraud claims in three key states
- January 2026: Plaintiffs filed an amended complaint adding new model years and states
- February 2026: Discovery phase expanded to include GM internal engineering documents
| Milestone | Date | Status |
|---|---|---|
| Initial Filing | 2020 | Complete |
| Motion to Dismiss (First) | 2021 | Denied in part |
| Amended Complaint | January 2026 | Filed |
| Class Certification Hearing | Expected mid-2026 | Pending |
| Settlement Talks | Late 2026 (projected) | Not yet started |
The discovery phase is where things get interesting. Plaintiffs' attorneys have requested GM's internal testing data on lifter durability, DFM calibration records, and warranty claim databases.
If those documents show GM knew about the defect before selling the vehicles, the case becomes much harder for GM to defend. Discovery documents have been the turning point in many auto defect cases.
Legal experts watching the case say settlement talks could begin in late 2026 or early 2027, depending on how class certification goes. GM has a financial incentive to settle before trial to avoid even larger damages.
Key Takeaway: The GM L87 engine lawsuit is progressing through federal court in 2026, with class certification and discovery representing the most important milestones this year.
GM Class Action Lawsuit Over Engine Defects
The GM class action lawsuit engine claims are not limited to the L87 alone. The broader legal action includes allegations against GM's 5.3L L84 engine, which shares the same AFM/DFM system and similar lifter design.
A class action lawsuit lets one group of plaintiffs represent thousands of other people with the same problem. Instead of each GM owner filing a separate case, the class action bundles everyone together for efficiency.
The proposed class includes anyone who purchased or leased a GM vehicle with the L87 or L84 engine from the 2019 to 2024 model years. Some filings seek to extend that range back to 2014, covering earlier AFM-equipped engines.
Key claims in the class action include:
- Breach of express warranty: GM promised reliable performance; the engines failed prematurely
- Breach of implied warranty: The vehicles were not fit for ordinary use
- Violation of the Magnuson-Moss Warranty Act: Federal warranty law protections were breached
- Unjust enrichment: GM profited from selling defective products
- Consumer fraud: GM concealed known defects from buyers
Class certification is the single biggest hurdle. If the court certifies the class, GM faces potential liability to hundreds of thousands of owners. That's when settlement pressure becomes enormous.
GM's defense strategy has focused on arguing that lifter issues are isolated, not widespread. But NHTSA complaint data and thousands of consumer reports contradict that position.
GM Engine Lawsuit: What You Need to Know
The GM engine lawsuit boils down to one question: did GM sell engines it knew were defective? Based on the evidence filed so far, plaintiffs say yes.
Here's what matters most if you own a GM vehicle with the 6.2L engine. Your vehicle might be part of this case even if it hasn't broken down yet. The lawsuit covers vehicles that have the defect, not just ones that have already failed.
Quick Facts:
- Engines covered: 6.2L L87 V8 and 5.3L L84 V8
- Model years: Primarily 2019 to 2024
- Number of NHTSA complaints: Over 3,000 related to lifter and valve train issues
- Average repair cost: $4,000 to $8,000
- Warranty coverage: Often denied after 60,000 miles or 5 years
You don't need to hire your own lawyer to participate. Class action lawsuits are handled by the lead attorneys, and class members typically pay nothing out of pocket. Legal fees come from any settlement or judgment.
The strongest evidence in your favor is documentation. Keep every repair receipt, dealership work order, and communication with GM. If your engine was replaced or repaired under warranty, those records still matter.
Think of it like this: every single repair receipt is a brick in the wall of evidence against GM.
GM L87 Engine Problems Behind the Lawsuit
GM L87 engine problems are the foundation of the entire lawsuit. The most common failure involves the hydraulic roller lifters that operate the intake and exhaust valves.
The L87 uses 16 lifters, and the DFM system actively deactivates up to 15 of the 16 cylinders in various combinations. Each deactivation cycle puts mechanical stress on the lifter's internal components.
Common symptoms owners report before a full lifter collapse:
- Ticking or tapping noise at startup that doesn't go away
- Rough idle or misfiring feeling
- Check engine light with codes P0300 through P0308 (misfire codes)
- Reduced engine power warning on the dashboard
- Metal shavings found in the oil during changes
- Sudden loss of power while driving at highway speed
| Problem | Frequency | Typical Mileage at Failure |
|---|---|---|
| Lifter collapse | Most common | 30,000 to 80,000 miles |
| Camshaft damage | Secondary | 40,000 to 90,000 miles |
| Pushrod failure | Secondary | 35,000 to 75,000 miles |
| Excessive oil consumption | Common | 20,000 to 60,000 miles |
| Valve seat damage | Less common | 50,000+ miles |
These aren't high-mileage failures on worn-out trucks. Owners are seeing catastrophic engine damage at 30,000 miles on a $60,000 vehicle. That's not normal wear and tear. That's a design flaw.
GM's own Technical Service Bulletins confirm the company was tracking these failures internally. TSB 18-NA-355, updated multiple times, addressed "engine tick noise" caused by lifter issues. The fix? Replace the failed lifters. But the replacement lifters often fail again because the root cause is the DFM system itself.
Key Takeaway: The L87 engine's core problem is a lifter design that can't handle the stress of GM's cylinder deactivation system, leading to failures at shockingly low mileage.
GM 6.2 Lifter Failure Lawsuit
The GM 6.2 lifter failure lawsuit specifically targets the component most responsible for engine damage: the hydraulic roller lifter. These small but critical parts are the weak link in the L87 engine.
A hydraulic roller lifter is about the size of your thumb. It sits between the camshaft and the pushrod, opening and closing the engine's valves. In a normal engine without cylinder deactivation, lifters live long, quiet lives.
But the DFM system changes everything. Each lifter has an internal locking mechanism that allows it to collapse on command, deactivating its cylinder. This mechanism cycles thousands of times during normal driving. Over time, the internal pin wears, the lifter loses oil pressure, and it collapses permanently.
When a lifter collapses, the engine doesn't just lose one cylinder. The collapsed lifter can break apart, sending metal fragments through the oil system. Those fragments score the camshaft, damage bearings, and contaminate the entire lubrication system.
Repair Scenario Breakdown:
| Repair Level | What's Needed | Estimated Cost |
|---|---|---|
| Minor (single lifter) | Lifter replacement only | $2,500 to $4,000 |
| Moderate | Lifters + camshaft replacement | $4,000 to $6,500 |
| Severe | Full engine rebuild or replacement | $7,000 to $12,000+ |
The lawsuit argues GM could have used a more durable lifter design or limited the frequency of DFM cycling. Instead, GM prioritized fuel economy ratings over long-term reliability.
Some aftermarket companies now sell "AFM/DFM delete kits" that disable the cylinder deactivation system entirely. The popularity of these kits speaks volumes about how widespread the trust issue has become.
GM AFM DFM Lawsuit and Cylinder Deactivation
The GM AFM DFM lawsuit targets GM's cylinder deactivation technology as the root cause of the L87 engine's problems. AFM (Active Fuel Management) is the older version. DFM (Dynamic Fuel Management) is the newer, more aggressive version.
AFM could deactivate four of eight cylinders. DFM can deactivate up to seven of eight cylinders in 17 different combinations. On paper, DFM sounds like brilliant engineering. In practice, it's putting enormous strain on engine internals.
| Feature | AFM | DFM |
|---|---|---|
| Cylinders Deactivated | 4 of 8 | Up to 7 of 8 |
| Patterns Available | 1 (V4 mode) | 17 different combinations |
| First Introduced | 2005 | 2019 |
| Engines Using It | L84 5.3L, older 6.2L | L87 6.2L, newer L84 5.3L |
| Lifter Cycling Frequency | Moderate | Very high |
The lawsuit alleges GM rushed DFM to market to meet Corporate Average Fuel Economy (CAFE) standards. Federal fuel economy rules pushed automakers to squeeze every fraction of an MPG from their engines.
GM chose cylinder deactivation over other solutions like turbocharging smaller engines or hybrid drivetrains. The result was an engine that tested well on EPA fuel economy cycles but destroyed its own components during real-world driving.
Plaintiffs also allege that the Valve Lifter Oil Manifold (VLOM), which controls oil flow to the lifters during deactivation, has its own design problems. Oil flow restrictions and solenoid failures compound the lifter wear issue.
The irony is that many owners report the fuel savings from DFM are minimal. Real-world testing shows maybe 1 to 2 MPG improvement. Owners are paying thousands in repairs to save a few hundred dollars in gas.
GM 6.2 Engine Valve Train Failure Claims
GM 6.2 engine valve train failure claims extend beyond lifters to the entire system of components that operates the engine's valves. The valve train includes lifters, pushrods, rocker arms, valve springs, and the camshaft.
When one lifter fails, it creates a domino effect through the valve train. A collapsed lifter means a bent pushrod, which means a damaged rocker arm, which can mean a dropped valve. A dropped valve hitting a piston is catastrophic. At that point, the engine is scrap.
The valve train failure claims in the lawsuit highlight three specific design issues:
- Lifter material quality: Plaintiffs allege GM sourced cheaper lifter components that don't meet durability standards
- Camshaft lobe profile: The camshaft's design creates excessive contact pressure on lifter faces during DFM operation
- Oil delivery system: The VLOM doesn't provide consistent oil pressure to lifters during rapid DFM cycling
Owners who have experienced valve train failure describe a terrifying sequence. The engine starts ticking. Within days or weeks, the tick becomes a knock. Then the check engine light comes on. Then the truck goes into limp mode on the highway.
Quick Facts:
- Valve train repairs average $5,500 at a GM dealership
- Complete engine replacement runs $8,000 to $12,000+
- Many failures happen between 35,000 and 70,000 miles
- GM's powertrain warranty covers 60,000 miles or 5 years (whichever comes first)
That warranty cutoff is a major pain point. Thousands of owners experience failure just outside the warranty window. Some at 62,000 miles. Some at 65,000. GM almost always denies goodwill coverage for these near-miss cases.
Key Takeaway: Valve train failures in the GM 6.2L engine go far beyond a single lifter and often result in total engine replacement at the owner's expense.
GM L87 Affected Vehicles: Full List
GM L87 affected vehicles include some of the best-selling and most profitable vehicles in GM's lineup. The 6.2L L87 engine is the premium powertrain option, and buyers paid a significant upcharge for it.
Here is the full list of vehicles equipped with the L87 6.2L V8 engine that fall within the scope of the lawsuit:
| Vehicle | Model Years | Trim Levels with L87 |
|---|---|---|
| Chevrolet Silverado 1500 | 2019 to 2024 | LTZ, High Country |
| GMC Sierra 1500 | 2019 to 2024 | SLT, AT4, Denali |
| Chevrolet Tahoe | 2021 to 2024 | RST, Premier, High Country |
| Chevrolet Suburban | 2021 to 2024 | Premier, High Country |
| GMC Yukon | 2021 to 2024 | SLT, AT4, Denali |
| GMC Yukon XL | 2021 to 2024 | SLT, AT4, Denali |
| Cadillac Escalade | 2021 to 2024 | All trims (standard engine) |
| Cadillac Escalade ESV | 2021 to 2024 | All trims (standard engine) |
| Chevrolet Camaro SS | 2019 to 2024 | SS (LT1 variant, similar issues) |
The Cadillac Escalade is particularly notable. Every single Escalade comes standard with the 6.2L V8. Escalade buyers paying $80,000 to $110,000+ are experiencing the same lifter failures as Silverado owners.
To check if your vehicle has the L87 engine, look at the eighth digit of your VIN. The code "J" typically indicates the 6.2L L87 engine. Your window sticker or build sheet from the dealership will also confirm the engine type.
Some earlier vehicles with the L86 version of the 6.2L (2014 to 2018) may also qualify under the broader class action. Those engines used the older AFM system, which had similar but less frequent lifter failures.
GM Engine Lawsuit Eligibility Requirements
GM engine lawsuit eligibility depends on a few specific factors. You generally qualify if you own or lease a GM vehicle with the L87 6.2L or L84 5.3L engine from the affected model years.
Here are the key eligibility criteria based on the current class action filings:
You likely qualify if:
- You purchased or leased a qualifying vehicle (see full list above) from the 2019 to 2024 model years
- Your vehicle has the L87 6.2L V8 or L84 5.3L V8 engine
- You experienced lifter failure, valve train damage, or related engine problems
- You paid out of pocket for repairs, even if the repair was partially covered by warranty
- You still own a vehicle with the defect, even if it hasn't failed yet
You may still qualify if:
- You sold the vehicle after experiencing problems
- Your vehicle was repaired under warranty (you may have suffered diminished value)
- You live in a state not yet included in the named class (the class may expand)
You likely do NOT qualify if:
- Your vehicle has a different engine (such as the 2.7L turbo four-cylinder or 3.0L Duramax diesel)
- Your engine problems are unrelated to lifters or the DFM/AFM system
- You purchased the vehicle with knowledge of the defect at a heavily discounted price
Keep in mind that class action eligibility can change as the case progresses. The court may narrow or expand the class during certification.
How to Join the GM Engine Lawsuit
Joining the GM engine lawsuit is straightforward. In most class actions, you don't need to actively "join" at this stage. If the court certifies the class, you are automatically included if you meet the eligibility criteria.
However, there are steps you can take right now to strengthen your position:
Step 1: Document everything. Gather all repair records, receipts, warranty claims, and service invoices. Photograph any visible engine damage.
Step 2: File an NHTSA complaint. Go to the NHTSA's vehicle complaint database and submit a formal complaint about your engine problem. This creates a federal record that strengthens the overall case.
Step 3: Contact a participating law firm. Several firms handling this case offer free case evaluations. Hagens Berman and Chimicles Schwartz Kriner & Donaldson-Smith are among the lead firms.
Step 4: Keep your vehicle records organized. Store everything in one folder: purchase agreement, loan documents, warranty booklet, every oil change receipt, and every repair order.
Step 5: Don't destroy evidence. If your engine was replaced, ask the dealership to keep the old engine or at least the failed lifters. Physical evidence can be powerful in litigation.
| Action | When to Do It | Why It Matters |
|---|---|---|
| Save all repair receipts | Now | Proves out-of-pocket costs |
| File NHTSA complaint | Now | Creates federal record |
| Contact lead law firm | Now | Ensures you're tracked as a class member |
| Photograph damage | Before repairs | Visual evidence of defect |
| Request failed parts | During repair | Physical evidence |
You won't pay anything to participate. Class action attorneys work on contingency. They only get paid if the case results in a settlement or judgment.
Key Takeaway: You don't need to file your own lawsuit to participate, but documenting your engine problems and contacting a lead law firm now will put you in the strongest position.
GM L87 Engine Settlement Prospects
The GM L87 engine settlement has not yet been finalized as of early 2026. The case is still in the pre-trial phase, and no formal settlement offer has been made public.
However, looking at similar auto defect class actions, we can project what a settlement might look like. GM has a track record of settling engine defect cases rather than going to trial.
Comparable GM Settlements:
| Case | Defect | Settlement | Year |
|---|---|---|---|
| GM AFM Lifter (earlier 5.3L) | Lifter failure, oil consumption | $102.6 million (proposed) | 2023 |
| GM Generation IV V8 Oil Consumption | Excessive oil use | $45 million | 2022 |
| FCA EcoDiesel Emissions | Emissions defeat device | $307 million (consumer portion) | 2022 |
| Ford PowerShift Transmission | Defective dual-clutch | $58 million | 2020 |
Based on these precedents and the scope of the L87 case, legal analysts estimate a potential settlement in the range of $75 million to $200 million, depending on how many model years and vehicles are included.
Several factors will influence whether GM settles and for how much:
- Class certification outcome: A certified class puts massive pressure on GM to settle
- Discovery documents: If internal GM documents show cover-up, settlement value rises sharply
- NHTSA involvement: Any investigation or recall demand from NHTSA changes the calculus
- Number of claimants: More documented claims mean higher total exposure for GM
Settlement talks are most likely to begin after class certification, which is expected in mid to late 2026. If talks start on schedule, a preliminary settlement agreement could emerge by early 2027.
GM L87 Lawsuit Payout: How Much Could You Get
The GM L87 lawsuit payout will depend on your specific circumstances, including your out-of-pocket costs, the severity of your engine failure, and the total settlement fund size.
Based on comparable auto defect class actions, individual payouts typically fall into tiered categories:
| Tier | Criteria | Estimated Payout |
|---|---|---|
| Tier 1: Full engine replacement | Paid for engine replacement out of pocket | $3,000 to $8,000 |
| Tier 2: Major repair | Paid for lifter and camshaft replacement | $1,500 to $4,000 |
| Tier 3: Minor repair | Paid for single lifter or pushrod repair | $500 to $1,500 |
| Tier 4: Warranty repair only | Engine repaired under warranty, no out-of-pocket cost | $100 to $500 |
| Tier 5: No failure yet | Own affected vehicle, no failure experienced | $50 to $200 |
These are estimates based on how similar settlements have been structured. The actual amounts won't be known until a settlement is reached and the payment formula is set.
Owners who spent $7,000 or more on out-of-pocket engine replacements will likely receive the highest individual payouts. Those who had warranty repairs may receive smaller amounts reflecting diminished vehicle value.
Think of it like insurance claims: the more you can document your losses, the larger your recovery. Receipts, invoices, and bank statements showing payments to repair shops are the most important evidence.
One thing to keep in mind: class action payouts rarely cover 100% of your actual losses. They typically cover 30% to 70% of out-of-pocket expenses. That's the tradeoff for not having to litigate an individual case.
GM Engine Class Action Settlement 2026
The GM engine class action settlement 2026 status is pre-settlement. No deal has been announced, but the legal process is on track for settlement discussions to begin this year.
Here's a realistic timeline of what to expect:
| Event | Projected Date |
|---|---|
| Class certification hearing | Mid-2026 |
| Class certification ruling | Late summer 2026 |
| Settlement negotiations begin | Fall 2026 |
| Preliminary settlement agreement | Late 2026 to early 2027 |
| Court preliminary approval | Early 2027 |
| Notice to class members | Spring 2027 |
| Claims filing period | Spring to fall 2027 |
| Final approval hearing | Late 2027 |
| Payouts begin | Late 2027 to early 2028 |
This timeline assumes the case does not go to trial. If GM refuses to settle or if the parties can't agree on terms, the case could proceed to trial in 2028. A trial verdict would likely mean larger potential damages but a longer wait for any money.
The claims filing process will require you to submit proof of your ownership and any repair costs. Typical documentation requirements include:
- Proof of vehicle ownership (title, registration, or purchase agreement)
- Repair invoices showing lifter, valve train, or engine work
- Payment receipts proving out-of-pocket expenses
- NHTSA complaint filing (helpful but usually not required)
- Vehicle mileage records at time of failure
Start gathering these documents now. Waiting until the claims period opens often leads to missing paperwork and smaller payouts.
Key Takeaway: No settlement has been finalized in 2026, but the legal timeline suggests preliminary agreement could come by late 2026, with actual payouts potentially starting in late 2027.
GM 6.2 Engine Recall Status
GM has not issued a formal recall for the 6.2L L87 engine as of early 2026. Despite thousands of NHTSA complaints and multiple Technical Service Bulletins, the company has avoided a recall.
The difference between a TSB and a recall is significant:
| Action | What It Means | Who Pays |
|---|---|---|
| Technical Service Bulletin (TSB) | GM tells dealers how to fix a known issue | Owner pays (unless under warranty) |
| Safety Recall | GM acknowledges a safety defect and must fix it for free | GM pays for all repairs |
GM has issued several TSBs for lifter-related noise and failure. The most notable is TSB 18-NA-355 and its updates. These bulletins instruct dealers to replace failed lifters and, in some cases, the camshaft.
But a TSB doesn't require GM to pay for repairs on out-of-warranty vehicles. Only a recall would mandate free repairs regardless of mileage or warranty status.
NHTSA has received over 3,000 complaints related to lifter and valve train issues in L87-equipped vehicles. The agency has opened preliminary investigations but has not yet ordered a recall.
For a recall to happen, NHTSA must determine that the defect poses a safety risk. Plaintiffs in the lawsuit argue that sudden engine power loss on a highway is absolutely a safety hazard. An engine that drops to reduced power mode at 70 MPH creates a dangerous situation.
If NHTSA orders a recall during the lawsuit, it would dramatically strengthen the plaintiffs' position. It would also mean free repairs for all affected owners, regardless of the class action outcome.
Owners should file NHTSA complaints to add to the formal record. Volume matters. The more complaints NHTSA receives, the more likely an investigation escalates to a recall order.
GM L87 Engine Repair Cost Breakdown
GM L87 engine repair costs are one of the main reasons this lawsuit exists. Owners are paying thousands of dollars to fix a defect they didn't cause.
Here's a detailed breakdown of what these repairs actually cost at a GM dealership versus an independent shop:
| Repair Type | Dealership Cost | Independent Shop Cost |
|---|---|---|
| Single lifter replacement | $2,800 to $4,500 | $1,800 to $3,000 |
| All 16 lifters + camshaft | $4,500 to $7,000 | $3,000 to $5,000 |
| Full valve train rebuild | $5,500 to $8,500 | $4,000 to $6,500 |
| Complete engine replacement (new) | $9,000 to $14,000 | $7,000 to $10,000 |
| Complete engine replacement (reman) | $6,500 to $9,000 | $5,000 to $7,500 |
| AFM/DFM delete kit installation | $2,000 to $3,500 | $1,200 to $2,500 |
These costs don't include rental car expenses, lost wages from missed work, or the hassle of being without your vehicle for days or weeks. Dealership repair timelines for lifter replacement average 5 to 10 business days. Engine replacement can take 2 to 4 weeks.
The AFM/DFM delete is worth noting. Many owners who've had lifter failures choose to install a delete kit during the repair. This disables the cylinder deactivation system entirely and replaces the DFM lifters with standard lifters. The tradeoff is slightly lower fuel economy but dramatically improved reliability.
Some owners have spent money on repairs multiple times. First repair at 40,000 miles. Second failure at 70,000 miles. At that point, cumulative repair costs can exceed $10,000 on a vehicle that's only a few years old.
These repair costs are the backbone of the damages claimed in the lawsuit. Every dollar you've spent on lifter and valve train repairs is a dollar you could potentially recover.
Key Takeaway: Repair costs for GM L87 engine defects range from $2,800 for a single lifter fix to over $14,000 for a full engine replacement, making this one of the most expensive consumer auto defect issues in recent years.
