purchased an m5 in september of 2010. Upon starting and driving for first time there was excessive shaking of vehicle and upon backing up noise that was groaning and creaking as if the vehicle was not attached securely to it frame. Vehicle never stops vibrating excessively. Very exhausting to drive. I'm being told that that is just the way this vehicle is. Tire was replaced on front left side but problems persist.

not sure if your problem has been dealt with but here is my experience with excessive vibration only under acceleration. after reading many posts i thought it would be the engine mount so i replaced main front mount but no improvement. next i changed the passenger side cv axle and the problem went away. i was guilty of driving with torn cv boot which allowed it to lose lubricant and eventually warp the shaft. cost was about $125(local parts supply not mazda)for the shaft and $15 for spindle socket. many posts on youtube to show you the procedure.

Have a tire shop visually inspect/check and rebalance all the other tires. That will be the least expensive venture. If all is well with tires/wheels, drive shafts/cv joints will be the next thing to look at that would cause persistant vibration at road speeds. Creaking/groaning from suspension components can be a simple lack of proper chassis lubrication, or it could be worn parts or metal-on-metal contact (where it shouldn't be) causing the noise.

Thank you for suggestions. Week before tire was replaced was told nothing was wrong with any tire. Felt as though a knot was on a tire. After taking vehicle back in and vibration was confirmed, tire was replaced. Dealer said front tire was a little high. The groaning in back area was supposedly fixed by them cleaning/sanding pads withBG stop squeal and coating pad backing plate with CRC disc brake quiet. according to them the noise was gone from front but could hear groaning from rear pads. They did the same to rear pads and said noise was gone, This did quiet the noise somewhat for a while but it gradually came back and vibration has never stopped. Can feel vibration under accelerator (almost like a tapping going on under my foot) and steering wheel pulls in jerks to right. About to take legal action because I feel I was sold a defective vehicle.
