Vibration at 70-80

[MarkG]

I have a ‘15 Q70L w/58000 miles. I put new Continental tires on it and started to feel significant vibration at 70-80 mph. Had the tires rebalanced, then rotated to no avail. Aligned and replaced brakes and rotors, and road force balanced Still vibration. Took the tires back and replaced. Still. What else might get it be?

Has the car been in accident??

Did you check your car bearings for damage? Or a driveshaft coupler?

You must need a complete check of your car, by a good car mechanic.

Has the problem been solved yet? If so, what did it take? I just bought a new to me 2015 Q70 AWD w/24K miles from Carmax. It needs a few issues addressed, one of which is a slight high speed steering/whole car vibration beginning at 70mph which worsens at 75+mph. Thanks in advance for any reply.

I haven’t found this board very helpful. Wow, this board is (insert your own descriptor). In this thread and on many others pertaining to the Q70, it’s mostly people posting issues/questions seeking responses, but few are forthcoming. For what it’s worth, my vibration seems to have been resolved with brand new front brake rotors done at Infiniti (at Carmax’s expense). Things at least what the service mgr said. I have yet to pick it up and drive it to confirm.
