My daughter's timing belt recently broke in her 2003 Saturn Vue - whuch resulted in the pistons destroying the "head" of the engine. Estimates are $3,500 - $4,000 to replace the engine. Is this symptomatic of only a certain type of engine - and, do we need to be concerned that the same thing could happen with a 2004 Lexus RX330 Engine? Further, how often should the timing belt be replaced? How do you know when it is necessary? Thanks!

YES, your Lexus could bend the valves as well, that is why you should replaces your timing belt every 6 years or at the mileage suggestion, even if the factory manual does not say to do so. After 6 years the belt material gets fatigued and cracks or can snap.
