They don't have any more problems with the timing belts than any other vehicle. That is covered under the new car warranty, which is normally 3 years or 36,000 miles, (which ever comes first)
They recommend replacing the timing belt, (for the 4 cylinder's) at 105,000 miles or 105 month intervals.
The single overhead camshaft engine's are non-interference, which means that there would not be any further damage to the engine if the belt were to break while driving.
Overall, it is not a very extensive job anyway.
The 6 cylinder engines use a timing chain rather than a belt.
