General Motors to face trial over defective Cadillac Lyriq crossovers

The lawsuit says the SUVs may stop starting, charging and driving at any time, Carscoops reports.

A class-action lawsuit against General Motors has been filed in federal court in Washington state, alleging that the Cadillac Lyriq electric crossover suffers from widespread defects in the electronics, software and battery management system that could suddenly render the vehicle completely inoperable.

According to the lawsuit, two Lyriq owners—Wendy Cochran of Washington and Charlene Riddle of Florida—saw their vehicles become completely unusable. Riddle said GM told her a software update was needed, but new firmware was not available at the time.

Cochran, in turn, not only lost time and incurred unplanned expenses, but also received a car that now costs significantly less than the amount paid for it. The lawsuit specifically notes that problems arise in the electrical system, battery control modules, and software, and the failure of one system can trigger a chain reaction and render the car completely immobile.

The key point of the lawsuit is that GM knew about the problem before sales began – based on pre-production testing, engineering reports, warranty claims, dealer records and customer complaints – but continued to market the Lyriq as a reliable premium electric vehicle.
