If you own or have owned a General Motors vehicle, there’s a real chance you’re owed money from a gm class action settlement and don’t even know it. GM has been hit with multiple class action lawsuits over defective engines, faulty batteries, broken shifters, and failing fuel pumps. Some of these settlements are already paying out, while others are still in progress. This guide breaks down every active and recent gm class action settlement, who qualifies, how much you could receive, and what you need to do.
There are multiple GM class action settlements in 2026. The biggest is a $175 million engine defect settlement for 2011-2014 Chevy and GMC truck/SUV owners (payments already being distributed, averaging $3,300+). Other active settlements cover Bolt EV batteries ($150M), diesel fuel pumps ($35M), and shifter defects. A new L87 V8 engine class action was filed in February 2026.

The $175 Million LC9 Engine Defect Settlement (The Big One)
The largest gm class action settlement currently paying out is the Siqueiros v. General Motors case, centered on a defective piston assembly in the LC9 5.3-liter V8 Vortec engine. This settlement alone covers more than 40,000 vehicle owners across three states and is delivering average payments exceeding $3,300 per vehicle.
What happened
GM installed Generation IV LC9 engines in several of its most popular trucks and SUVs from 2011 to 2014. These engines contained an inherently defective piston ring assembly that caused excessive oil consumption. Over time, this led to spark plug fouling, rough idling, check engine lights, engine shutdown commands, and in some cases, permanent engine damage. Many owners reported having to add oil between changes at alarming rates.
Who qualifies
You are part of this gm class action settlement if you own or owned any of the following vehicles with an LC9 engine manufactured on or after February 10, 2011:
- 2011-2014 Chevrolet Avalanche
- 2011-2014 Chevrolet Silverado
- 2011-2014 Chevrolet Suburban
- 2011-2014 Chevrolet Tahoe
- 2011-2014 GMC Sierra
- 2011-2014 GMC Yukon
- 2011-2014 GMC Yukon XL
Important: The main settlement (Siqueiros) covers California, Idaho, and North Carolina. Oklahoma has a separate $24.8 million settlement (Hampton v. General Motors) covering the same vehicles for Oklahoma residents.
How much you could receive
Each eligible class member receives no less than $2,149, with average payouts exceeding $3,300 per vehicle. The exact amount depends on the pro rata distribution of the $175 million fund among qualified claimants. For the Oklahoma settlement, payouts range from $700 to over $2,000 depending on documented losses and repair history.

Check My EligibilityThe $150 Million Chevrolet Bolt EV Battery Settlement
The second major gm class action settlement involves the Chevrolet Bolt EV and Bolt EUV battery defect that created a serious fire risk, leading to one of the largest automotive recalls in recent history.
What happened
LG Energy Solution manufactured battery packs for the Chevrolet Bolt that contained defective cells capable of overheating and catching fire during charging, especially when charged to full capacity. GM issued multiple recalls starting in 2020, eventually recalling every Bolt EV and Bolt EUV ever produced. The defect posed a genuine safety risk, with the NHTSA confirming at least 13 reported fires linked to the battery issue.
Who qualifies
The settlement class includes all persons and entities in the United States who purchased or leased a model year 2017, 2018, 2019, 2020, 2021, or 2022 Chevrolet Bolt EV or Bolt EUV that was built and shipped to a dealer on or before August 19, 2021, and who did not receive a buyback of their vehicle. That covers more than 102,000 vehicles.
Current status
Judge Berg issued the Final Approval Order on December 22, 2025. The main claim deadline was July 31, 2025. If you previously submitted an opt-out request but changed your mind, you had until March 23, 2026 to submit a claim. Eligible claimants can expect payouts between $700 and $1,400 per vehicle from the $150 million fund.
The $35 Million Diesel Fuel Pump Settlement
This gm class action settlement addresses a defective Bosch CP4 high-pressure fuel pump used in diesel versions of the Chevrolet Silverado and GMC Sierra. The CP4 pump was designed for European diesel fuel standards and was incompatible with American diesel, leading to premature wear, metal contamination throughout the fuel system, and complete engine failure.
Who qualifies
Owners of 2017-2020 Chevrolet Silverado and GMC Sierra diesel trucks equipped with the CP4 fuel pump. The settlement was finalized in May 2025.
Payout details
- Owners who paid for CP4 repairs: $6,356 to $12,712 depending on the number of valid claims
- Owners who did not pay for repairs or no longer own the vehicle: $400 to $800
The stark difference in payouts reflects the significant cost of CP4 fuel pump repairs, which can run $8,000 to $12,000 out of pocket.
The Shift to Park (Shifter Defect) Settlement
The Jefferson & Riley v. General Motors case addressed a defective electronic shifter that prevented certain GM vehicles from recognizing when they were placed in park. Affected vehicles displayed a persistent “Shift to Park” warning message, prevented the ignition from turning off, and drained the battery.
Who qualifies
Initial purchasers and lessees of these vehicles in Ohio (or 2017-2018 Acadia in Tennessee):
- 2017-2019 GMC Acadia
- 2019 Chevrolet Blazer
- 2016-2019 Chevrolet Malibu
- 2018-2019 Chevrolet Traverse
- 2016-2019 Chevrolet Volt
Final approval was granted October 9, 2025. Qualifying class members receive a $500 cash payment plus up to $375 in reimbursement for out-of-pocket repair expenses. The claim deadline was August 19, 2025.
Pending GM Lawsuits to Watch
Beyond the settled cases, there are two significant gm class action lawsuits in early stages that could result in future settlements.
A consolidated class action complaint filed on February 26, 2026 alleges a dangerous bearing defect in GM’s L87 6.2-liter V8 engine that can cause total engine failure without any warning signs. Owners report sudden and catastrophic engine failure while driving. Hagens Berman has been named interim co-lead counsel. This case is in its early stages, and no settlement has been reached.
A class action filed in Pennsylvania federal court alleges GM sold 2025 Chevrolet Traverse, GMC Acadia, Buick Enclave, Chevrolet Colorado, and GMC Canyon vehicles with defective master brake cylinder assemblies. This case is also in its early stages.
If you own a vehicle affected by either of these pending lawsuits, document any issues (engine failures, brake problems) and keep repair receipts. These records could be critical if settlements are reached. If you want to understand how to join a class action lawsuit, that guide walks through the process.
How to Make Sure You Don’t Miss Any GM Settlement Money
The manual approach
- Bookmark the official settlement websites (gmenginelitigation.com, boltevbatterysettlement.com, gmfuelpumplitigation.com)
- Set calendar reminders for key hearing dates
- Check your mail for official settlement notices (including forwarded mail if you’ve moved)
- Search settlement databases regularly for new filings involving GM
The automated approach
MoneyPilot scans for class action settlements you qualify for, tracks deadlines automatically, and alerts you when action is needed. Instead of monitoring five different settlement websites, you get one dashboard that handles everything. If you qualify for any of the gm class action settlement cases above (or others you don’t know about), MoneyPilot surfaces them for you.
This is especially useful because GM lawsuits aren’t the only ones out there. There are dozens of major settlements open right now across automotive, consumer products, data breaches, and financial services. Most people qualify for several and never find out.
What to Watch For: Scams Targeting GM Settlement Claimants
High-profile automotive settlements attract scammers. Protect yourself:
- No legitimate settlement administrator will ask for payment to process your claim. GM settlement claims are free to file.
- Official communications come from verified settlement websites with court-authorized domain names (e.g., gmenginelitigation.com, boltevbatterysettlement.com).
- Never share your full Social Security number unless you’re submitting a W-9 through the official settlement portal.
- If someone calls claiming to be from a “GM settlement office,” hang up and contact the settlement administrator directly through the official website.
If you’re not sure what you qualify for beyond GM, the MoneyPilot settlement tracker has a running list of every verified, court-approved case with deadlines and estimated payouts.
