General Motors is facing a proposed class action lawsuit in the United States over alleged software and electrical defects in its Cadillac Lyriq electric sport utility vehicle.
The complaint, filed on April 2 in Washington on behalf of two drivers, alleges that defects in the Lyriq’s software and electrical systems can render the vehicle inoperable, preventing it from starting, charging or operating.
According to the filing, affected vehicles may require towing and extended service periods, with some repairs reportedly taking weeks or months.
The plaintiffs allege that General Motors was aware of the issues through internal testing, engineering reports, warranty claims and consumer complaints before the lawsuit was filed.
The complaint further claims the automaker failed to disclose the alleged defects while marketing the Lyriq as a premium electric vehicle.
The plaintiffs are seeking remedies including disclosure of the alleged defects, repairs, consumer notification and restitution.
General Motors declined to comment on the lawsuit.
The Cadillac Lyriq has been on the market since 2022. Industry data cited in the filing shows annual sales of 28,402 units in 2024 and 20,971 units in 2025.
