Vibrations when going 85-100 Km/h
 

Hello,
I own a Suzuki Grand Vitara, long, model 2014, 2.4 Engine. The car has driven 60,000 Km.
When going between 85Km/h to 100Km/h, there is a vibration in the car, mostly felt on the steering wheel and on the seat.
Even when I let got of the gas pedal, or even put the gear in Neutral, the vibration continues, so long as the car is in that speed range.
I had the wheel rebalanced and the front adjusted but the problem persists.

I recently had new stabilizer bars installed in the front.

Did anyone encounter such issue? how did you solve it?
