wipers come on when car started, sometimes in garage but most times after sitting outside in heat. sometimes come on while driving down road. vandergriff Toyota says to put wipers in manual and turn on when rain starts. this now makes it non automatic. they claim the can not duplicate this problem. guess they are calling me a liar. in 17 days (21 june to 8 july) this problem has happened on 7 days and sometimes more than once per day. talked to Toyota service and they don't seem very concerned about this problem. after many Toyota's and 2 being avalons I guess the next won't be a Toyota.
