This case involves claims arising from Plaintiffs’ purchases or leases of certain Honda or Acura vehicles with the Auto Idle Stop feature. Plaintiffs allege that the Auto Idle Stop feature in the Class Vehicles is defective because the engine may not automatically restart when a driver releases the brake pedal, which can leave the vehicle temporarily undrivable (“AIS No Restart”). Plaintiffs further allege that American Honda Motor Co., Inc. (“Honda”) was aware of the alleged defect. Plaintiffs seek to recover economic damages they claim arises from the purchase or lease of the vehicles. Honda denies any wrongdoing or liability for the alleged claims. Honda also denies that the Auto Idle Stop feature is defective and contends that a software update and a warranty extension it has made available for the Class Vehicles addresses any potential Auto Idle Stop issue. Plaintiffs and Honda (the “Parties”) have agreed to the Settlement to avoid the time, expense and uncertainties of litigation.
