Does the vibration change with vehicle speed?

Does it feel like the shake is in the steering wheel or in the seat?

Customer: replied 6 days ago.
It's in the seat and it's the worst at 10 3 km/h
Expert:  Jared D replied 6 days ago.

If the vibration is the the seat then there are two likely causes:

The first would be a tire issue in one of the rear tires. This can be pinpointed by rotating the back tires to the front. If the shake moves to the front then the tire/wheel is definitely the problem.

The other option is a bent or unbalanced driveshaft. The dealer should be able to pinpoint that using a run out gauge.

Is it worse when lightly accelerating?

No

I would definitely suspect a tire issue in that case. Have a shop swap them from front to back and see if the vibration moves to the steering wheel.
