A Cadillac Lyriq EV defect lawsuit was filed against General Motors on April 02, 2026 over allegations of serious electrical, software, battery management and charging-related defects that caused the electric SUVs to become nonfunctional.
The lawsuit, filed in the U.S. District Court for the Western District of Washington, alleges that General Motors was aware of these significant defects while marketing the luxury electric vehicle, which entered production in 2022.
The lawsuit alleges that Cadillac Lyriq defects can trigger system failures that leave these EVs unable to start, charge, or operate at all – defeating the purpose of purchasing a vehicle in the first place.
What is the Cadillac Lyriq defect lawsuit about?
Two plaintiffs, Wendy J. Cochran of Washington and Charlene Riddle of Florida, are alleging in a class action lawsuit that General Motors knew of significant defects in several systems essential to the Cadillac Lyriq EV’s functionality and released the vehicle to the public anyway.
GM’s marketing materials had touted the Cadillac Lyriq as an innovative electric luxury vehicle with brand new technology.
“LYRIQ was conceived to make every journey exhilarating and leverages more than a century of innovation to drive the brand into a new era, while rewarding passengers with a more personal, connected and immersive experience,” Jamie Brewer, Cadillac LYRIQ chief engineer said in a release. “To do this we developed an architecture specifically for EVs. It is not only an exceptional EV, but first and foremost a Cadillac.”
Cadillac Lyriq sales grew quickly after launch, with reported U.S. sales of 9,154 in 2023, 28,402 in 2024 and 20,971 in 2025.
However, the lawsuit alleges a sharp discrepancy between General Motors’ marketing materials and its pre-release knowledge of significant issues with the vehicle’s actual functionality.
“GM has long known of these defects through pre-release testing, internal engineering reports, warranty claims, dealership repair reports, [National Highway Traffic Safety Administration] complaints, and/or consumer reports,” the lawsuit alleges.
“Despite this knowledge, GM continued to market the Cadillac Lyriq as a reliable luxury electric vehicle, listing the vehicle at a premium price. GM failed to disclose the defects to consumers. As a result, Plaintiffs and class members purchased vehicles that are defective, unreliable, unsafe, and worth substantially less than represented.”
What defects are alleged in the Cadillac Lyriq lawsuit?
The lawsuit alleges that the Cadillac Lyriq electric SUV suffers from “defects in its electrical architecture, software systems, battery management modules, and vehicle control networks that can cause the vehicle to become nonfunctional or ‘bricked,’ rendering it incapable of starting, charging, or operating.”
Put simply, the numerous alleged defects in the Cadillac Lyriq EV defeat the entire purpose of purchasing a vehicle at all, and vehicle “bricking” can allow drivers and passengers to get stranded while driving.
What problems are Cadillac Lyriq owners reporting?
Cadillac Lyriq EV owners included in the lawsuit report:
- Vehicle will not start
- Vehicle will not charge
- Vehicle becomes inoperable
- Vehicle experiences system failures or “bricking”
Lyriq owners also report dealerships being unable to repair their vehicles promptly, which leaves the vehicles inoperable for weeks or even months.
How has General Motors responded to these Cadillac Lyriq defects?
According to the complaint, General Motors had offered to repurchase some defective Cadillac Lyriq EVs but had delayed completing those buybacks. It is suspected that General Motors has delayed buybacks to mitigate the financial impact.

How do class action lawsuits work?
A class action lawsuit is often brought by one or more named plaintiffs on behalf of a proposed class. In this case, two Cadillac Lyriq EV owners filed a lawsuit on behalf of Lyriq owners who allegedly experienced broadly similar vehicle issues that may stem from a common defect.
In general, the plaintiffs must ask the court to certify a proposed class. If the court certifies the class, class members are typically notified and may be given an opportunity to exclude themselves, also known as opting out. Notice and opt-out procedures can vary depending on the type of class action.
Class actions may result in settlements divided between individual class action members. Distributions are not always equal. The amount a class member receives can depend on settlement terms, type of claims involved, documented losses and other criteria approved by the court.
How does the Cadillac Lyriq defect lawsuit affect my lemon law rights?
If a class member misses the exclusion deadline and does not opt out of a certified class action, that person may be bound by the outcome of the case and may lose the ability to pursue separate claims that are covered by the class action.
In this case, potential members of the Cadillac Lyriq defect lawsuit may not be able to pursue individual claims under their state lemon laws for the same defects if they fail to opt out before the exclusion deadline.
Because class action participation can affect your ability to pursue an individual lemon law claim, it may be wise to speak with a lemon law lawyer before making any decisions about your legal options.
