What Is the GM Cadillac Lyriq Lawsuit About? Cochran, et al. v. General Motors LLC

The lawsuit was filed in the U.S. District Court for the Western District of Washington and centers on claims that the Lyriq’s complex electronic architecture is prone to failure. The complaint argues that faults within the vehicle’s software, battery management systems, and vehicle control networks can trigger a cascade of communication breakdowns. Because the Lyriq runs entirely on electrical systems, plaintiffs argue these failures are not minor glitches — they render the vehicle completely useless.

The lawsuit asserts violations of the Magnuson-Moss Warranty Act (a federal law requiring manufacturers to honor written warranties), the Washington Consumer Protection Act, the Washington Product Liability Act, and the Florida Deceptive and Unfair Trade Practices Act. Plaintiffs seek a nationwide class covering all Cadillac Lyriq owners and lessees whose vehicles suffered these defects.

The lawsuit further alleges that GM knew about these defects before selling the vehicles — based on internal testing, warranty data, dealership repair records, and consumer complaints — yet continued marketing the Lyriq as a reliable luxury EV. GM has declined to comment on the case.

Who Is Eligible for the GM Cadillac Lyriq Lawsuit?

You may qualify as a class member if:

• You purchased or leased a Cadillac Lyriq in the United States (model years 2023, 2024, or 2025 are referenced in complaints)
• Your vehicle experienced electrical system failures, inability to start or charge, software crashes, battery management failures, or control module communication breakdowns
• Your vehicle required towing to a dealership due to an electrical or software-related failure
• Repairs took weeks or months without a permanent resolution
• You received no adequate compensation from GM despite reported defects

U.S. sales of the Cadillac Lyriq totaled 9,154 in 2023, 28,402 in 2024, and 20,971 in 2025, meaning tens of thousands of potential class members may exist nationwide. Consumers who experienced similar electrical failures in other GM Ultium platform vehicles should also track related litigation,

Potential Recovery & Legal Theory

Plaintiffs are seeking compensatory damages, diminished vehicle value, out-of-pocket repair costs, loss of vehicle use, and restitution for overpayment on a defective product. Plaintiff Charlene Riddle specifically alleges damages including loss of vehicle use, diminished value, out-of-pocket costs, and overpayment for a defective vehicle.

Under the Magnuson-Moss Warranty Act, consumers can sue when a manufacturer fails to honor a written warranty on a consumer product costing more than $25. The Cadillac Lyriq — priced between approximately $58,000 and $73,000 — easily clears that threshold. If the court certifies a nationwide class, recovery could extend to all U.S. Lyriq owners who experienced qualifying defects.

The lawsuit further contends that although GM has claimed to offer a “buy back” program for affected vehicles, it has intentionally delayed the program’s rollout to avoid payouts. Plaintiffs are requesting a jury trial.

How to Join the Lawsuit

This is a proposed opt-out class action. If the court certifies the class, you will be automatically included as a class member without taking any action — as long as you meet the eligibility criteria above.

You do not need to contact a law firm to preserve your potential rights at this stage. However, if you want to:

1. Document your vehicle’s failures — photograph error codes, save repair orders, and record all dealer communications
2. File a complaint with NHTSA — visit nhtsa.gov and submit a vehicle safety complaint to create an official record
3. Contact lead counsel — reach Pfau Cochran Vertetis Amala PLLC at their official website if you wish to share your experience with the plaintiffs’ legal team
4. Monitor the case docket — track filings at PACER under Cochran, et al. v. General Motors LLC, U.S. District Court for the Western District of Washington
5. Preserve all records — keep all purchase or lease documents, repair receipts, and correspondence with GM or dealers

If you want to opt out and pursue an individual claim, watch for the court’s class certification notice, which will specify the opt-out deadline. Missing that deadline forfeits your right to sue separately.

Frequently Asked Questions

Do I need a lawyer to join this lawsuit?

 No. If the court certifies Cochran, et al. v. General Motors LLC as a class action in the Western District of Washington, Cadillac Lyriq owners who qualify will be automatically included. You only need a lawyer if you intend to pursue an individual lawsuit separate from this case.

Is this lawsuit legitimate?

 Yes. The case was filed April 2, 2026, in the U.S. District Court for the Western District of Washington and covered by Law360 on the date of filing. The plaintiff law firm, Pfau Cochran Vertetis Amala PLLC, is a Seattle-based litigation firm with verified federal court filings.

When will a settlement be reached? 

TBD — this case is in early litigation. Class certification has not yet been granted. A settlement, if any, could take one to three years depending on how GM responds and whether the court certifies the class.

What if I already accepted a GM buyback offer?

 Accepting a buyback or repair offer from GM may affect your ability to participate in this class action. Consult a consumer protection attorney before signing any release of claims with GM.

Will any settlement payment affect my taxes?

 Potentially yes. Payments classified as compensation for economic loss (repair costs, diminished value) may differ in tax treatment from punitive or emotional distress damages. Consult a tax professional once any settlement is reached.

What specific defects does the lawsuit cover?

 The complaint covers failures involving control module communication, battery management systems, and charging systems — specifically defects that cause the Lyriq to become completely inoperable (“bricked”) without warning.

My Lyriq was repaired but broke down again — do I still qualify? 

Potentially yes. The lawsuit specifically alleges that repair technicians have struggled to permanently fix the underlying defect, and that repeated failed repairs are part of the harm. Document every repair attempt with written dealer records.

What is the Magnuson-Moss Warranty Act? 

The Magnuson-Moss Warranty Act is a federal law that allows consumers to sue manufacturers in federal court when a written warranty is not honored. It is one of the key statutes cited in this case because GM’s written warranty promised a reliable vehicle that plaintiffs say it failed to deliver.
