Assalamualaikum everyone!
I've Daihatsu Mira 2012. I feel vibration when driving at a speed of 30-45 kmh. When i accelerate the car and increase the speed, the vibration removes.
Also, it happens only in D gear, not in S.
Also, i would like to mention, what kind of vibration it is. Its like when we put a manual car in high gear and keep the speed slow, and car feels low power. It is like that and can be felt on Steering and through the echo inside the cabin.
