I took my Toyota Sienna '06 to a mechanic to replace a timing belt. Not a family garage - a chain. It took them twice longer than usual to do the job and they returned the car saying everything was ok. I had to come back three more times due to squealing belts. On the fourth time another problem occurred and I demanded a refund. They agreed. However, the mechanic at Toyota dealer found a few damages, which potentially could lead to the timing belt damages and as a result the car stall or worse. I want to take them to the court for lying to me and putting my family's life in danger - can I go through small claims court given that the current damages were not significant, but potential damage could be disastrous?
