I'm having a slight vibration in the car/steering wheel and seat when I'm driving at around 65KM. Dealer has installed new tires, wheel alignment and still getting this vibration with only 9,000KM on the car. When I picked up the car the vibration wasn't so noticeable, while at the dealer I also drove a 2019 with 10,000KM XJL with the same vibration. I was told by the dealer that the vehicle need to be driven more, as the vibration was due to the car sitting on the lot. I find this hard to believe, being car guy. A vibration is a vibration, no matter how you put it.
This is my first Jag. I purchased this care with CPO warranty, but the vibration is taking the fun out of driving!

Any help or suggestions would be appreciated.

Here are some pictures of the car.

 

Ah ... this subforum is for the XJ from 2003 to '09, ie the X350/358; you need to post in the X351 subforum.

 

I had a similar issue a while back. It was the drive shaft bearing. The rubber around it had rotted away and there was play in the shaft.
