Hi In common with many I have had to have the transaxle on my MkI Prius (2001) replaced (at 118K miles). With the help of the Toyota service staff, I purchases a reconditioned transaxle (2 year part warrant). Right after I got the vehicle back I noticed a slight vibration on the steering wheel. It is most noticeable on the highway at higher speeds when one throttles back, taking one's foot of the accelerator. The front tires have been rebalanced. Vibration is perhaps a misnomer for what I experience; it is more like a kind of pulsing with a definite period. It seems unlikely that this pulsing sensation is pure coincidence. Should I worry that this newly installed transaxle is somehow misaligned? Is it indicative of a failure? No warning lights on. Thx Rob Stevens
This vibration sounds like a defective mg2 ... When u release ur foot from the throttle the mg2 starts regenerating power using the movement of ur car ... doing the function of regen. breaking.... If the stator of the mg2 have a defect in one of the phases u r gonna feel this puls ...also when accelerating on slow speed will feel that puls too The mg2 is inside the transaxle assembly so am willing to bet that u ended up going back to that dealer for ur warranty Hope this answer can be useful
