Are there problems with Subaru timing belts?

Hello and welcome to Just, Super mechanic here. Please DON’T hit accept until you are completely satisfied with the answer. About your vehicle.

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.


DOHC Interference
SOHC Free-Wheeling

Overall, it is not a very extensive job anyway.

The 6 cylinder engines use a timing chain rather than a belt.

Yes, they mentioned the chain rather than the belt. In the case discussed the timing chain broke, damaged other parts, and had to replace the engine. This is an older model and bought used. I was just wondering if it was universally a problem, something that Subaru was working on, or that it had been fixed? thanks
Not a very common problem for the chains to break but it does happen, now and then. With the 6 cylinders, the engine will bend valves when the chain lets go and sometimes break a head, or valve, which can damage the cylinder wall.

It seems that if the engine is not maintained correctly, that the timing chain guides wear out, (from not enough lubrication) and inavertently cause the chain to wear out and/or break.
