Don't remember a recall on these. Are you sure it's a timing chain and tensioner? The cost of repair could be steep. I don't remember if these were a free wheeling engine or not. If the chain skips or breaks, there could be valve and/or piston damage. that gets expensive. It would be best to ask a dealer to see if there are any recalls or TSBs on this vehicle. I don't think that particular issue was addressed. I've heard of a few with those troubles, but can't say for sure if there was any factory involvement outside of standard warranties.
