GM Sued Over Cadillac Lyriq Defects: EVs Allegedly Become Inoperable Without Warning
What’s the Problem
A new class action lawsuit has been filed against General Motors over alleged defects in the Cadillac Lyriq, Cadillac’s flagship electric vehicle. According to the complaint, some vehicles can suddenly become completely inoperable—unable to start, charge, or function at all.
Plaintiffs describe situations where the vehicle essentially becomes “bricked,” leaving owners stranded and requiring towing to a dealership. This is not being framed as an isolated glitch, but rather a systemic issue tied to core vehicle systems.
Allegations
The lawsuit, filed as a proposed nationwide class action, alleges that the defects involve critical vehicle systems, including the battery, charging components, and control modules. Owners claim the failures occur without warning and that repeated repair attempts often fail to resolve the problem.
The complaint further alleges that GM knew about these defects before selling the vehicles. That alleged knowledge is said to come from internal testing, warranty data, dealership repair records, and consumer complaints. Despite this, GM allegedly continued marketing the Lyriq as a reliable luxury EV.
Recall / TSB Background
The allegations do not exist in a vacuum. The Cadillac Lyriq has already been subject to multiple recalls and reported issues, many of which relate to software integration, electrical systems, and braking performance.
There have been recalls tied to braking system defects that could reduce stopping performance, along with electrical system failures affecting displays and vehicle functionality. In addition, stop-sale actions have reportedly been issued in the past due to unresolved software and hardware integration issues. These prior problems provide context for the claims now being raised in litigation.
Symptoms
Owners experiencing issues with the Cadillac Lyriq have reported a consistent pattern of serious failures. Vehicles may refuse to start or power on, fail to charge, or display warning messages related to battery or system faults. In more severe cases, the vehicle becomes entirely nonfunctional.
Many owners report that these issues require towing and result in extended periods where the vehicle is out of service. Repeated dealership visits without a lasting repair are a common theme.
How to Proceed
If you are experiencing issues with a Cadillac Lyriq, early documentation and consistency are critical.
Keep detailed records of every repair visit and all communications with the dealership or manufacturer. Make sure your complaints are accurately written on every repair order when you drop the vehicle off.
If the same issue continues after multiple repair attempts, or if your vehicle has been out of service for an extended period of time, it may qualify as a lemon under California law.
Pay close attention to any warning signs, especially loss of power or charging failures. These are not minor inconveniences in an electric vehicle and should be addressed immediately.
If repairs are unsuccessful or the issues continue to return, you should contact Valero Law to evaluate your rights and potential remedies.
