A loud clanking, slapping sound suddenly began coming from under the hood while driving. The car was driving fine before and during. I did not feel safe driving, so I pulled over and had the car towed. The service center was able to diagnose the problem as the main drive belt and tensioner. The belt was in bad shape. It cost $300 to replace.

My car started up fine no noise, no clicking, nothing. I put it in reverse and it just stopped, I kept trying to start it wouldn't turn over and it hasn't started since. I was told its the timing belt. It hasn't been fixed yet I'm sending it to a shop next week.
