2009 Toyota RAV4 SUV Sport 4dr SUV (3.5L 6cyl 5A)
Trans axle noise 35 mph to 55 mph
 Vehicle did not make  transaxle noise when purchased! After 1500 miles it started a howling noise at light throttle, 35-55 mph it is getting worse, Toyota Tech is supposed to be checking on the reason for it, it has been 21 days and I have heard nothing, I am very dissatisfied with this car! I was told there was a production change, I think I got one of the bad ones.  The service dept. replaced an axle at about 5 thousand miles and the axle bearing, but this did not correct the noise I am hearing.
