There are 2 owner-reported driver assist & adas complaints for the 2018 Nissan Leafin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The malfunction warning light came on to indicate that the automatic braking system was not working. I brought the car to the dealership, which quoted me $1900 for a new sensor. I have read about accidents and near collisions due to the malfunctioning of this system and am now worried that there might be sudden braking that others have experienced. I would like to get this system fixed, but do not believe consumes should need to pay $2000 to repair a defective system.
AEB system malfunction around 25000 miles. Dealer diagnose as the front radar failed and cause the cruise control not available.
