I had a similar issue, replaced the front and rear central mounts, didn't solve it. Turned out it was the transmission support mount, its a two piece unit. Main section bolts onto the left inner fenderwell, other section bolts to the top of the transaxle. The two pieces are helkd togehter by a bolt from the bottom thru the rubber isolators. On mine the bolt FELL OUT. I had already special ordered the new mount from the dealer at around $180.00 and they wouldn't accept a return, so I now have an extra mount short of one metric bolt.
Check that mount. A sure sign of the bolt fallout is a clunk when backing up and or hard accel and torque steer. (car pulls one way or another when accel and goes the other way on decel)
Install procedure says you should have the dealer re-align the motor to prevent torque steer and unnecessary wear on CV joints/suspension.
