We had many sudden ghost stops when Leaf sensors misinterpreted an obstacle while in moving traffic . Another thing was Collision warning ⚠ light coming on while in the settings showing as ON . Lastly , our first long drive after lockdown we turned on the pro pilot in the 50 mile an hour stretch of the motorway and car lost power , was rolling and slowing down and warning ⚠ came on about sensor not activated . Shouted at hubby to turn pro pilot off and then power came back Luckily, roads were mostly empty ... Finally today car is at Nissan garage and they just phoned to say no abnormalities detected during software tests and will take it to the motorway to see if fault appears . Could anyone care to help me out here as what’s likely to be happening?
