Cadillac Lyriq Owners File Class Action Lawsuit Over Battery Issues

Cadillac Lyriq Owners File Class Action Lawsuit Over Battery Issues...

A proposed class action lawsuit filed this week alleges Cadillac Lyriq electric SUVs suffer from defective battery systems that unexpectedly lose power. The complaint, filed in U.S. District Court in Michigan, claims General Motors failed to properly disclose the issues affecting the luxury EV's 102 kWh Ultium battery pack.

The lawsuit comes as Lyriq sales surged 350% last quarter, making it one of GM's fastest-growing EV models. Owners report sudden power loss incidents occurring at highway speeds, with some vehicles requiring complete battery replacements. GM has issued three technical service bulletins related to Lyriq battery management since 2024.

Plaintiffs allege the battery defects create safety hazards and significantly reduce vehicle range. The case cites 127 complaints filed with NHTSA, including 18 reports of complete propulsion loss. GM spokesperson Maria Rayner told Automotive News the company is reviewing the complaint but stands behind its battery technology.

The lawsuit seeks compensation for repairs, diminished value, and a recall if defects are confirmed. Legal experts note this marks the first major challenge to GM's next-generation Ultium platform, which underpins multiple electric models. Court documents show the case could cover all Lyriq vehicles sold in the U.S. since 2023.

Consumer Reports recently removed its recommended rating for the Lyriq due to reliability concerns. The lawsuit's filing coincides with increased scrutiny of EV battery performance following similar cases against Ford and Hyundai. GM shares dipped 1.4% in early trading following news of the legal action.
