570GT - Shaking Steering Wheel

[John-Dem]

Picked up a 2017 GT three weeks ago. Within 10 minutes of driving it out of the dealership, at over 80mph, the steering wheel was shaking more than Shakin Stevens suffering from Parkinsons on ten litres of coffee.

Took the car back two days after collecting it. It was re-balanced/re-tuned as one of the wheels was out of sync. They couldn't/wouldn't test the car at 70+mph, but assume it's fixed.

Take the car out the next day, and the problem still very much exists. Have taken videos of my hands on the steering wheel clearly showing the vibration, and will send to dealer tomorrow.

Anyone experienced this, and any other issues that this could be a symptom of ?

Thanks for the feedback and suggestions.

Sent the dealer a couple of videos, and they agree with a couple of posters here, that it could be the noise-cancelling foam inside the tyres coming loose. They said they don't automatically check for that issue as the re-balance/re-tune should pick that up, and they did notice a discrepancy with one of the tyres which they rectified.

It goes back to the dealer next week.

In the meantime, a buzzing sound is coming from a rear B&W speaker, so will get that checked too.
