is it still under warranty?

 

[Bass_Waves]

Powertrain yes. 3k miles from dealer yes. Took it to dealer and they need car to look into ut during week and if I do that im careless to go to work

bet the balance is off, could have lost a weight, remember tire guys are usally the lowest on the shops totem pole. the rims could be not true... loose lugs, bad hub, faulty tire i.e. manufactuer defect or snapped belt or internal sidewall tear. slightest chance it's a horribly warped rotor.

Well tires are balanced. Alignment is str8. Rotors a maybe just cause driverside looks like crap. I may be getting better mounts eventually but I got a warranty and don't know if it interfere with it

if it were the rotor you would also feel pulsation under braking hence i said slight chance.

Yeah I know. No pulsations there though. I am starting to believe my 1st gear pull is torque steer and the 60-70mph shake is from aftermarket rims. Dunno though. It sorta don't do it much now.
