Didn't seem to have any vibration but after a month or so I started getting a vibration on throttle around 45mph that gets horrible around 50mph then smooths back out 70+ JUST as you state pretty much.

If you let off at 50mph the vibration promptly stops. The issue persists on the old wheels/tires and with the ECU flashed back to stock. It's a really boomy sound in the cabin at 50mph that drives me nuts and only happens when on throttle no matter if 5% or 100% throttle it does it. 0% throttle, instantly gone.
I am at 49k miles now and out of factory warranty (past 4 years). I do have CPO though and probably will take it in. Should I try and lead them to it being a drive shaft issue? Did you get yours replaced and issue resolved? I've had very poor luck with both my local dealerships in the past and dread going to the dealer. I usually do all my own maintenance. |
The exact same thing on my car (but the shaking/vibrations started around 50 mph and went to 65 mph or so) was completely fixed by balancing the tires.
