Steering may not behave as designed
The engine current sensors have not been calibrated correctly which could lead to an increased recuperation torque during vehicle deceleration. An increased recuperation torque during deceleration could lead to a vehicle oversteer condition in the i3 and vehicle understeer condition in the i8. This could lead to skidding on slippery roads during driving.
Fix: Recall the vehicles that are likely to be affected and calibrate sensors for measuring the engine current.

This could over time result in the fuel tank leaking. The driver will become aware of the leak either by the smell or dripping fuel after refuelling.
Fix: Recall all affected vehicles and inspect the fuel tank. If necessary replace the fuel tank.
