Subaru has been struck with a lawsuit filed in the U.S. District Court for the District of New Jersey, and the plaintiffs allege that the EyeSight driver assistance systems, comprising automatic emergency braking, lane keep assist, and reverse automatic braking, are defective, and that the company sold its cars despite being aware of the problem.According to a report by Carcomplaints.com, the lawsuit reveals eight Subaru models have been affected by the issue:“All persons residing in the United States, including its territories, who purchased or leased, other than for resale, any of the following vehicles: 2023-2026 Subaru Legacy, Outback, and Ascent vehicles; 2024-2026 Subaru Impreza and Crosstrek vehicles; 2022-2026 Subaru Forester and WRX vehicles; and 2025-2026 BRZ vehicles.”AdvertisementAdvertisementMaine plaintiff Alexander Hall alleged that the automatic emergency braking activated on his 2024 Subaru Forester within one year of ownership, even when no objects were present on the road. He mentioned one incident in particular where his Forester stopped suddenly and was almost hit by another vehicle from behind.A brown suv drives down a blurred road.In addition, the lane keep assist also proved to be problematic, since it shifted him to another lane when nothing was blocking his way.Laurene Germano, the other plaintiff from Virginia, alleged that her 2024 Subaru Crosstrek had emergency braking problems. On one occasion, the vehicle braked suddenly to 15 mph, due to which she suffered minor injuries.The plaintiffs allege that faulty programming has caused the defects in the Subarus in question. The lawsuit reads:AdvertisementAdvertisement“The Defects in Class Vehicles are caused by the poor calibration of the systems, including their cameras and sensors, and faulty programming of the system control modules (particularly their ability to decide when to command other control modules including, for example, the antilock brake system control module and the TCM to apply the brakes and stop the vehicle in the middle of traffic).”The lawsuit further alleges that the lane keep assist function goes against the driver’s input due to “poor software calibration, impacting multiple control modules, including the Power Steering Control Module, such that the LKA feature resists driver input when the driver is attempting to change lanes or driving on a road with construction barriers, or malfunctions when the road has multiple lines due to construction.”Not only that, but the lane keep assist can also prevent the vehicle from changing lanes. Both plaintiffs reported that the feature can steer their Subarus into other vehicles.The owner’s manual explains the limitations of the systems allegedly deemed defective. The lawsuit does not mention if the plaintiffs read the owner’s manual or the sections related to EyeSight systems.
