I just purchased my 07 SR about 8 weeks ago and I have always been suspect that there was something going on with the AWD system. Are you supposed to be able to spin the front tires at all? It feels as though I can get them to spin, one or two full rotations, then the rears kick in. Is this normal? Dealer told me they updated the software but it continues to happen. I am used to 4wd on trucks and have not had any experiance with AWD. Any help would be great.
