I have an 07 WRX with only an SPT intake and SPT exhaust, no other mods.

My car left me stranded because it wouldnt start.

Shop says that my timing belt "jumped" a tooth or two.

Why would this happen? Has this happened to anyone else?

I got stuck with a $400 bill to realign the same belt.

I hit a deer in May around 18k miles on my car and showed no signs of mechanical issues for 4 months until just last week when it wouldnt start.

The deer damaged the radiator, frame, and belt cover (the one on the drivers side.) The belt in that damaged belt cover (not timing belt) got sheared and that was replaced also.

The car now has 23k miles on it.

This problem is not covered under warranty.

I do not abuse/race my car and I rarely go past 6k RPMs.

Can anyone share their issues and help me figure this out?

I really dont want my car to do this again, thanks!
