The auto giant filed a motion Tuesday with a federal court in Santa Ana, saying attorneys for Toyota drivers had failed to identify any defects in the vehicles.
Hundreds of lawsuits were filed against Toyota after the automaker began recalling millions of vehicles because of acceleration problems in several models and brake glitches with the Prius hybrid.
All of the federal cases were consolidated and assigned to a federal judge in Santa Ana.
Some plaintiffs claimed Toyota's electronic throttle control system has a defect.
On Tuesday, lawyers for Toyota said there was no evidence of a flaw.
