petrifiedrabit I wish i would have read your post sooner.
3 times now it's been back to the dealership in a month. I've talked to the General Manager and he agrees that if it happens again he will exchange the car for another.
I was told that this is the third Aveo in Canada that is having this problem...the dealership has been in touch with Chev who is apparently guiding them through.
They are now giving me $500 worth of gas cards because of the whole ordeal.
I believe the lemon law is 90 days here.
