Timing belts get replaced as a maintenance item in the manual, but timing chains are supposed to last the life of the engine. The 2010 Corolla gasoline engine indeed has a timing chain. Timing chains are not a standard serviceable item. Timing chains, like any item, can break. A broken timing chain in a noninterference engine will not cause engine damage, but the vehicle will still immediately shut off and not run. A timing chain break in an interference engine will cause the vehicle to shut off and also damage the pistons and valves, leading to expensive engine repairs. It is likely that the 2010 Corolla is an interference engine, but their timing chains are reliable. They tend to get replaced only if broken or possibly in a major engine overhaul.
