2009 Toyota Corolla - cam gear

I own a 2009 Corolla LE and I’ve never heard of that particular problem until now. I bought the car 9 years ago with 58k on the odometer and it has 120k now. I guess it’s possible the work was done under warranty before I bought it. In any event, your Corolla originally carried a 5yr.60k powertrain warranty so no, it’s not covered. Go ahead and have the camshaft timing gear replaced and the timing chain too while the shop is at it. It won’t be cheap, mainly because of labor, but it’s better than replacing the whole car.
