I have an 05 G6, last week I took my car in because I had a faulty hood latch which was preventing my remote starter from working, they fixed it, and since they fixed it, I heard this strange knocking under the hood. Just a knock, ABSOLUTELY NO OTHER PROBLEMS. So, I took it back to the same place, and they looked at it and say its my flywheel. HOW? Its an 05 with 70K miles on it, HIGHWAY miles ONLY, and I dont drive like a maniac, and I dont push or pull anything with my car, its basically to get back and forth from my house to school 45 minutes away. I'm really frustrated. How can it be a flywheel?
