I have a nissan murano 3.5. And I dont know whats wrong with it because everytime when im driving and I pass the 60 miles the car starts to shake and then when I hit the break the car shakes more. And I dont know what whan be the problem. Thank you for you time and I will be waiting for your answer
I would have the tire balance checked and complete front end part inspection for the high speed vibration, the vibration you feel when braking is probaly warped brake rotors, usaully fixed by replacing or turning rotors.
