Lexus IS power steering failure

My 2017 Lexus IS with a gasoline engine has a power steering issue at 164041 km. The steering wheel vibrates, handling is spongy, and there's an error code. Steering also requires more effort, suggesting power steering failure. The error points to a defective cable or plug connection, could this be the problem? Has anyone else had similar electric steering issues?

Vibrating wheel and spongy feel? That's not good. Did you check the power steering fluid level? Has the wheel alignment been checked recently? A bad alignment can cause steering issues.

Thanks! I forgot to mention this IS has electric power steering, so there's no fluid reservoir. The wheel alignment hasn't been checked recently, but could a misaligned wheel cause an intermittent failure and a stored error code?

Ah, electric steering, right. The stored error code is key. Sounds like a failing sensor or a bad connection. Get it scanned at a workshop. Could be a cheap fix, could be worse. Don't ignore it.

I had the vehicle scanned. It was a defective plug connection in the power steering system. The repair, including diagnostics and parts, cost 95€. Thanks for the help!
