Questions about this case?
AI Legal Assistant · free · answers in seconds · general information, not legal advice
There is no single General Motors class action. As of October 2026, five matters drive the searches: a $150 million Chevrolet Bolt battery settlement whose payments are on hold during an appeal, a pending lawsuit over the 6.2L L87 V8, a federal privacy case over OnStar driving data, and two engine and fuel-pump settlements that have already paid out. None of them has an open claim form today.

What the GM Lawsuits Are About
Each General Motors lawsuit below is a separate case with its own court, class and status. All describe allegations; GM denies wrongdoing in each.
Chevrolet Bolt batteries. Owners of 2017–2022 Bolts alleged that the battery packs, supplied by LG, carried a fire risk. GM and LG settled.
6.2L L87 V8. The lawsuit alleges a “defective design that causes insufficient lubrication between the bearings and the crankshaft” in about 600,000 trucks and SUVs, which can lead to spun bearings and engine failure. GM recalled about 600,000 vehicles in April 2025 and says the recall fixes the problem.
OnStar driving data. The plaintiffs allege GM collected driving behavior through OnStar and Smart Driver and sold it to data brokers such as LexisNexis and Verisk, whose reports went to car insurers. For the full privacy story, see our GM data privacy lawsuit page.
Older engine and diesel cases. Owners alleged excessive oil consumption in LC9 5.3L V8 engines and failing Bosch CP4 fuel pumps in 2011–2016 Duramax diesel Silverado and Sierra trucks. Both settled. Details are on our GM engine settlement page.
Case Details
Bolt: In re Chevrolet Bolt EV Battery Litigation, No. 2:20-13256, U.S. District Court for the Eastern District of Michigan, Judge Terrence Berg. Final approval December 22, 2025.
L87 engine: Powell et al. v. General Motors, LLC, No. 4:25-cv-10479, Eastern District of Michigan. Eleven suits were consolidated into it.
OnStar data: In re: Consumer Vehicle Driving Data Tracking Litigation, MDL No. 3115, No. 1:24-md-03115, Northern District of Georgia, Judge Thomas Thrash.
CP4 fuel pump: Chapman v. General Motors LLC, No. 2:19-cv-12333, Eastern District of Michigan, Judge Terrence G. Berg.
LC9 engine: Siqueiros et al. v. General Motors LLC, No. 3:16-cv-07244, Northern District of California, Judge Edward M. Chen.
Status as of October 2026: Five Cases, No Open Claim Form
L87 engine — pending, no settlement. GM moved to dismiss in June 2026, arguing the recall and a 10-year/150,000-mile engine warranty already address the issue. We found no ruling as of October 2026.
OnStar data — active MDL, no settlement. On April 22, 2026 the court narrowed the claims but let more than 40 go forward, including Wiretap Act claims. Separately, the FTC finalized an order against GM and OnStar on January 14, 2026. That order pays consumers nothing.
CP4 fuel pump — paid out. Initial payments went out March 23, 2026 and additional and residual payments August 31, 2026, per the settlement website. The 50% repair reimbursement program ended May 6, 2026.
LC9 engine — paid out. Checks went out from December 23, 2025. Reissued checks had to be cashed by September 24, 2026.

There's no claim deadline yet. We'll email you if a settlement opens a claim period.
Are You Affected?
Bolt: owners and lessees of 2017–2022 Bolts shipped to a dealer on or before August 19, 2021 — over 102,000 vehicles. Only people who filed a claim before the deadline will be paid.
L87: the proposed class covers owners of GM trucks and SUVs with the 6.2L L87 V8, including the Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon and 2021–2024 Escalade. Nothing to sign up for.
OnStar: the proposed nationwide class is described as 16 million drivers whose OnStar data was allegedly shared. No class is certified.
CP4: buyers of 2011–2016 Duramax Silverado or Sierra diesel trucks from a GM dealer between March 1, 2010 and September 13, 2024 in seven states. Claims closed November 6, 2025.
Transmissions: The 8-speed transmission class action suit against General Motors covers 2015–2022 vehicles, but no class is currently certified and no settlement exists. If you drive a GMC, our GMC lawsuit page covers model-specific cases.
Is There a General Motors Settlement Paying Now?
CP4: a settlement valued at $50 million, already distributed.
LC9: a $150 million fund paying at least $2,149 per class vehicle, already distributed.
L87, OnStar, transmissions: no settlement, no fund, no claim form. Any General Motors settlement in those cases would be announced by a court-appointed administrator.

Three Things to Watch For
Several real GM settlements plus several unsettled lawsuits make it easy for imposters to sound legitimate:
“Release your Bolt payment” fees
Bolt payments are frozen by the appeal, not by paperwork. Nobody can speed them up for a fee, and the real administrator does not ask for bank logins or gift cards.
“Claim your L87 or OnStar settlement” sites
Neither case has settled, so there is no claim form. A page asking for your VIN, driver’s license or Social Security number to “register” is collecting data, not filing a claim.
Fake check-reissue emails
The CP4 and LC9 settlements have already paid out and the LC9 reissue cutoff passed on September 24, 2026. Real messages come only from GMFuelPumpLitigation.com or GMEngineLitigation.com addresses.
General Motors Class Action — Questions People Actually Ask
Is there a General Motors class action I can join right now?
Not by filling out a form. Whatever class action lawsuit General Motors owners have read about, as of October 2026 no General Motors class action has an open claim period. In the L87 and OnStar cases you are included automatically if a class is certified or a settlement is reached.
When will Chevy Bolt settlement payments arrive?
No date is set. Final approval came December 22, 2025, but class counsel says payments are on hold pending a Sixth Circuit appeal. As of the latest report we found, from July 7, 2026, that appeal was still pending.
How much will the Bolt settlement pay?
Up to $1,400 for 2020–2022 Bolts that received the software remedy, and at least $700 for vehicles that got a new battery or were sold or returned early, per the filed settlement terms. Only people who submitted a claim are paid.
Is there a GM L87 engine settlement?
No. Powell v. General Motors is pending in the Eastern District of Michigan, and GM has asked the court to dismiss it. Separately, the recall gives affected vehicles a 10-year/150,000-mile engine warranty.
Did GM pay drivers over OnStar data sharing?
No. The FTC order finalized January 14, 2026 restricts GM’s data practices but includes no payments. The private class action, MDL No. 3115, is still pending with no settlement.
I got a CP4 fuel pump check. Is it real?
Probably. The Chapman settlement, run by JND Legal Administration, issued initial payments March 23, 2026 and further payments August 31, 2026. Verify through GMFuelPumpLitigation.com or 1-866-848-0815, not a number in the letter.
What happened to the GM transmission class action?
In June 2025 the Sixth Circuit decertified all 26 state subclasses in the 2015–2019 case and sent it back to the trial court. A separate 2020–2022 case has not reached class certification. Neither has settled.
What should GM owners do right now?
Complete any open recall on your VIN, keep repair receipts and correspondence, and keep any settlement notice you received. If you filed a Bolt claim, watch for direct contact from the administrator.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
