My windshield wipers stopped working. after a visit to the shop, i learned that my micro computer was not working and needed to be replaced. this repair cost $729. after some research i found that this is a very common problem with mazda 3s made around 2008. my car is only 5 years old with fairly low mileage, i believe that a defective part caused the problem and this issue should be evaluated for recall and reimbursement. thank you. *tr
