Car started rattleing when first starting. shortly after my check engine light came on and it was running rough all the time then. brought it to a mechanic and found out it's the timing chain. super expensive to replace and per. forums looks like tons of people with the 2006 srx had this problem as well. nothing but constant repair bills with this crossover. i feel it is a safety issue as it could break at any time from being loose. i feel this should be recalled and replaced.
