    I have a Auris 2016 with Prius gen lll enigne (22.000 km). When the engine is warm there is a rough vibrating deep sound (hard to descripe) at around 60 km/h (37-40 mph) with the HSI-needle pointing just above "eco"-text and the ICE almost just idling. When adding gas or letting go of the gaspedal so that just MG is pulling, it runs smoothly. The problem has been there for last three month.

    When getting service they can't see any problems from the readouts.

    Any explanations and solutions???

    Two strange sounds, any ideas? Clunk hybrid to engine, vice versa. Strange subtle knocking
