Mirai Electric Steering Vibration

My 2015 Toyota Mirai (electric) has 44724 km and the power steering is acting up. The steering wheel vibrates and feels spongy. The error memory logged a fault. It's harder to steer, like the power steering is failing. I suspect a bad cable or plug. Anyone else seen this with their Mirai's electric steering?

A 2015 Toyota Mirai owner experienced issues with the electric power steering, including vibration and spongy handling, and suspected a bad cable or plug. The problem was confirmed to be a faulty connection in the power steering system. A professional technician identified and repaired the loose connection, resolving the issue.

I own a Mirai and had similar symptoms last year: vibrating steering wheel, spongy handling. Any specific error codes? Did you check the steering pump fluid level?

I noted the error codes, something about the electric power steering module. I thought the Mirai uses electric power steering, so no hydraulic pump or reservoir. What was your experience?

Right, the Mirai uses electric steering. It was a faulty connection, like you thought. Get it checked by a professional, steering is dangerous. I recommend a workshop.

Thanks for confirming my suspicion about the connection. I took it to a technician, who found a loose connection in the power steering. The repair was 95€ and fixed it. Thanks for the help.
